Question

What is the iris of the eye? What are it's components?

Answer 1

- The colored part of the eye - Composed of two muscles: **dilator pupillae**, which opens the eye under sympathetic stimulation; **constrictor pupillae**, which closes the pupil under parasympathetic stimulation

Answer 2

- A dissociative disorder in which individuals feel detracted from their own mind and body (depersonalization), or from their surroundsings (derealization) - Example of depersonalization: an "out of body" experience - Example of derealization: giving the word a dreamlike or insubstantial quality

Answer 3

Internal migration is human migration within one geopolitical entity, usually a nation-state - Internal migration tends to be travel for education and for economic improvement or because of a natural disaster or civil disturbance

Answer 4

- the 'satiety center' - provides signals to stop eating - lesions in this part of the brain lead to obesity

Answer 5

**Stage 1:** preindustrial society; birth rate and death rate are both high **Stage 2**: improvements in healthcare, nutrition, sanitation and wages cause death rates to drop **Stage 3**: improvements in contraception, women's right and a shift from an agricultural to an industrial economy cause birth rates to drop; also, with an industrializing society, children tend to be in school longer and may be need to be supported by parents for a longer time, leading also to fewer children (lower birth rate) **Stage 4**: an industrialized society; birth and death rates are low Stage 5 (?): We haven't gotten here yet, so unsure of what will happen

Answer 6

- The tendency for a stimulus, similar to the conditioned stimulus, to elicit a response similar to the conditioned response - The more similar the new stimulus is to the conditioned stimulus, the greater the conditioned response will be Example: every time the door bell rings (neutral stimulus), its the neighbor coming over to give the dog a treat; after a while, the dog begins to get excited (conditioned response) when the door bell rings (conditioned stimulus); one day, the phone rings, and the dog also gets excited, since the door bell and phone sound similar; this is generalization

Answer 7

- Hippocampus and frontal cortex have the highest number of glucocorticoid receptors (cortisol) - See atrophy of these tissues after over-abundence of stress - Thus, if there is damage to the brain, it can affect behavior - **Depression**: one of the major emotional effects of stress - Includes anhedonia (not caring) - learned helplessness (learn, since the control is ripped out of your hands, that you don't have control) which leads to taking less and less control of your life; lose ability to identify coping mechanisms - **Anger** - A study looking at what type of people were at higher risk of heart disease, found there was one group, which they labeled "Type A", who were more competitive, easily angered, reactive etc., that were at higher risk; this was actually because these people have higher stress levels and thus the heart attack rates - **Anxiety** - With the fight-or-flight response, we have fear and fear causes anxiety (since the amygdala is repsonsible for all of these emotions) - **Addiction** **-** Poor coping mechanisms - Also frontal cortex is damaged; impairment reduces planning and judgement

Answer 8

- A depressant drug - Enhance the affinity of GABA to the GABA receptor in order to open up more chloride channels - Short-acting and intermediate-acting benzos are prescribed as sleep aids; long-acting are prescribed more for anxiety

Answer 9

Me: The part of us that is responding to the generalized other (society) I: Responds to the "me" and is the active aspect of ourselves Example: The "Me" might see that after high school, society expects us to go to college; the "I" might take that information and then decide if that's what is best for ourselves, or if I should travel first or take a year off to work

Answer 10

- includes intervations that rally around symptom reduction of psychological disorders; i.e. that any disorder has roots in biomedical disturbances and thus the solution should also be of a biomedical nature - Fails to take into accoutn many other sources of disorders, such a lifestyle and SES - Focuses on the physical abnormalities and how to use medicine to fix them

Answer 11

- Abnormalities of the mind that cause distress or disability - Can affect the higher functions of the brain, such as cognition, emotion and consciousness - Tend to come to the attention of other people by abnormalities of behavior

Answer 12

- The amygdala is responsible for feelings of fear and anxiety as well as anger and violence (this is what happens if you stimulate the amygdala) - If you destroy the amygdala, then you create a more "mellow" animal - Part of the limbic system

Answer 13

- When a group isolates themselves, voluntarily, from the main group, usually in order to maintain part of their identity - Religious or cultural factors that they identify with may be different than the main group Example: Amish - Note: This is different than social exclusion because there are fewer external factors making this decision, and the choice is voluntary

Answer 14

- Increases sensitivity to colors, sounds, tastes and smells (hallucinogen part of marijuana) - Also reduces inhibition and motor coordination and perceptual skills (so more like alcohol) - Can also effect memory formation and disrupt short term recall - THC stays in the body up to a week; thus, regular users need less of the drug, rather than more, to get the same high

Answer 15

Strengths - Does a good job of explaining how and why societies change Weaknesses - Does not explain how societies remain stable - Doesn't explain concepts of unity within a society

Answer 16

A child with the anxious-avoidant insecure attachment style will avoid or ignore the caregiver – showing little emotion when the caregiver departs or returns. The child will not explore very much regardless of who is there. - They did not exhibit distress on separation, and either ignored the caregiver on their return (A1 subtype) or showed some tendency to approach together with some tendency to ignore or turn away from the caregiver (A2 subtype). - Theorised that the apparently unruffled behaviour of the avoidant infants is in fact as a mask for distress, a hypothesis later evidenced through studies of the heart-rate of avoidant infants.

Answer 17

- While in REM sleep and dreaming, the prefrontal cortex activity is reduced - This is the part of the brain that is responsible for logic and critical thinking and if it's not working as much as normal, then we may not realize how weird our dreams are

Answer 18

- Somatosensory cortex: associated with feeling (touch, temperature, pain, pressure, etc.) - Spatial manipulations: helps us to understand where we are in space and where other things are relative to us - For example: The frontal cortex could help us in planning to reach out and get a cup of coffee and to move to get that cup of coffee, but the parietal lobe will allow us to figure out where that coffee cup is relative to us

Answer 19

Thought broadcasting: the belief that one's thoughts are broadcast directly from one's head to the external world Thought insertion: the belief that thoughts are being placed in one's head - A symptom of schizophrenia

Answer 20

- Thr right hemisphere - Somatosensation occurs contralaterally

Answer 21

- In making adaptive choices, middle-aged and older adults attempt to preserve and maintain existing internal and external structures; and they prefer to accomplish this objective by using strategies tied to their past experiences of themselves and their social world

Answer 22

- Involves working with the patient to find intrinsic motivation to change - Considered a very focused, very goal- directed type of therapy - Usually very few sessions and is a gateway to group sessions, CBT, etc.

Answer 23

- Not a specific disease - an overall term that describes a group of symptoms associated with a decline in memory or other thinking skills severe enough to reduce a person's ability to perform everyday activities - Alzheimer's disease patients account for 60-80% of dementia

Answer 24

- Respond to deep pressure and vibration

Answer 25

- States that people perform actions in order to maintain an optimum level of arousal: seeking to increase arousal when it falls below their optimal level, and to decrease arousal when it rises above their optimum level

Answer 26

- Items which are similar to one antother, tend to be grouped together by the brain

Answer 27

- This theory states that we go from possessing elementary mental functions to higher order mental functions by intereacting with a more knowledgable observer (MKO) - However, what we can learn from the MKO has to be within the Zone of Proximal Development, an area of learning that can be achieved with assistance; things outside of this zone cannot be learned, regardless of whether or not we have assistance

Answer 28

Subjective experiences that are accompanied by cognitive, physiological and behavioral changes and reactions Example: Suprise birthday party - Physiologically: might feel shocked, heart rate goes up, muscles tense - Cognitively: assess what is going on, expectations about the situation (might be fun); can also bring about emotions (might feel happy because you love the idea of parties) - Behavioral response: smile, open arms to hug friends and family, or clap hangs - Note: These responses vary culture to culture

Answer 29

- **Authoritarianism**: a form of government characterized by strong central power and limited political freedoms. Individual freedoms are subordinate to the state and there is no constitutional accountability under an authoritarian regime - **Dictatorship:** Where a single person holds that power, and usually includes mechanisms to quell threats over this power; occurs without the consent of the citizens

Answer 30

- An age group or generation, who have all lived through certain events in a certain time that affected their lives similarly Example: Baby boomers

Answer 31

- Our personality can be explained as the result of our genes - Genetics lead to traits which lead to our behaviors and personality - To study this theory, they look at identical twins who were raised apart from each other; even though twins were raised apart, they still had certain characeristics that were similar between the two _Similarities between twins raised apart:_ - **Social potency trait**: the degree to which a person assumes leadership and mastery roles in a social situation - **Traditionalism**: the tendency to follow authority

Answer 32

- Mimics Broadbent's Theory, except that they moved the selective filter until after things were assigned meaning - Thus, the selective filter processes what meaning things have and that is moved onto your conscious perception

Answer 33

- States that the retina contains two kinds of photoreceptors: those specialized for light-and-dark detection; those specalized for color detection

Answer 34

Tend and befriend response: a behavior exhibited by some animals, including humans, inresponse to threat. It refers to protection of offspring (tending) and seeking out the social group for mutual defense (befriending) - Related to release of oxytocin when in stress - The other option: we can engage in fight-or-flight, in which the sympathetic system leads ti increased HR and respiratory rate, etc. and endocrine system releases cortisol, epinephrine and norepineprhine

Answer 35

- A collection of neurons in the midbrain, right next to the ventral tegmental area - Part of the basal ganglia - Projects dopamine up to the striatum, another part of the basal ganglia - Parkinson's: the link between the substantia nigra and the striatum isn't working (there is not dopamine being released from the substania nigra into the striatum)

Answer 36

- A form of segregation in which there is clustering of various groups within a neighborhood

Answer 37

- Sexual drive is related to testosterone levels in both males and females - Sexual activity increases testosterone, which in turn increases sexual drive

Answer 38

- Respond to deep ressure and texture

Answer 39

- Immigration can benefit an economically successful country by increasing the number of available people able to join a work force, while taking the economic stress of the immigrants home country, which is usually under economic strain - However, this can also lead to the exploitation of immigrants

Answer 40

- Simplified principles used to make decisions; usually called "rules of thumb" Types: - Means-end analysis: analyze the main problem and break it down into smaller problems, then we attack the biggest sub-problem in order to reduce the most current state and our goal state - Working backwards: Start with the goal state and use it to suggest connects back to the current state; commonly used in mathematical proofs

Answer 41

- When our behaviors are only reinforced some of the time - Partial reinforcement schedules are important because they are generally more resistant to extinction than continuous reinforcement Four schedules of partial reinforcement: - Fixed- Ratio - Fixed-Interval - Variable-Ratio - Variable-Interval

Answer 42

- The hypothesis attempts to explain why people scapegoat - The theory says that frustration causes aggression, but when the source of the frustration cannot be challenged, the aggression gets displaced onto an innocent target. Example: if a man is disrespected and humiliated at his work, but cannot respond to this for fear of losing his job, he may go home and take his anger and frustration out on his family

Answer 43

- the tendency to believe that the world is just and that people get what they deserve. - Because people want to believe that the world is fair, they will look for ways to explain or rationalize away injustice, often blaming the person in a situation who is actually the victim - good things happen to good people; bad things happen to bad people

Answer 44

Rods: 120 million Cones: 6 million

Answer 45

- A score going from 0 (total segregation) to 100 (no segregation/perfect distribution), which is used to determine how segregated a community is

Answer 46

**Internal locus of control**: we can control our own fate or destiny - Example: After failing a test, we respond by saying that we shoud've studied harder **External locus of control**: there are outside forces, beyond our control, which determine our fate - Example: After failing a test, we believe that it was because the test was too hard and there was no studying we could've done that would've changed the result

Answer 47

Functionalism believes that mass media: - provides us with entertainment - acts as an agent of socialization and an enforcer of social norms - provides a collective experience for that society - important in community building - functions to show us what is right and wrong - promotes materialistic culture and consumerism

Answer 48

- Thought influences language - Only once we develop a certain way of thinking can we then develop language to describe those those - Example: only when children develop the ability of object permanence, do they learn words like "gone," "missing," and "find"

Answer 49

- Increases cerebrovasular health (remember stress can lead to coronary artery disease and hypertension, etc) - Increases neurogenesis

Answer 50

- The claim that in contrast to interpretations of their own behavior, people place undue emphasis on internal characteristics of the agent (character or intention), rather than external factors, in explaining other people's behavior - Example: if someone is late to a meeting, by engaging in this fundamental attribution error, we are likely to say that the person is irresponsible (blame the person), rather than the train was running late (blame the environment)

Answer 51

- His theory is based on the assumption that we all have three major dimensions, and that these three dimensions of personality encompass all traits that we all posses, but the degrees to which we individually express them are different Three major dimensions: - Extraversion: degree of sociability - Neuroticism: emotional stability - Psychoticism: the degree to which reality is distorted - He stated that we all have varying degrees of extraversion, neuroticism, but not necessarily psychoticism

Answer 52

- When the separation of groups occurs with one group in the center and the other group around this centered group

Answer 53

Neurochemical lesions are a type of experimental ablation - **Excitotoxins**: chemicals that bind to glutamate receptors and cause an influx of calcium into the neuron at such an extent that it kills the neuron - Example: Kainic Acid - Effective because it destroys the cell bodies of the neurons in the area, but not affect the axons of the neurons that are just passing by - **Oxidopamine (6-hydroxydopamine):** selectively destroys dopaminergic and noradrenergic neurons - Mechanism: oxidopamine is reuptaken by the pre-synpatic nerve since it looks like dopamine and kills these neurons - Allows us to be specific to the location of the neurons, but also to the type of neuron

Answer 54

- Control the lower motor neurons - Somas are found mainly in the cerebral cortex - Axons descend down to synpase onto lower motor neurons in the brain stem or the spinal cord

Answer 55

- Chorionic villi are formed: fingerlike projections that are derived from the trophoblast cells, which penetrate the endometrium - As this happens, the endometrium is proliferating and comes to cover the oocyte

Answer 56

- The difficulty in satisfying multiple requirements the requirements of the same role Note: different than role conflict, which is the difficulty in sastisfying expectations of multiple roles

Answer 57

The process of merely identifying a piece of information that was previously learned - Far easier than recall

Answer 58

- That social movements are motivated by a rlative deprivation, or a decrease in resources, representation or agency relative tto the past or to the whole of society - Require three things: that there is a feeling of relative deprivation, a feeling of deserving better, and a belief that conventional methods are not going to change things Example: From this viewpoint, the civil rights movement was a movement in response to the inequality and oppression faced by people of color in the U.S.

Answer 59

- When there is both Broca's aphasia and Wernicke's aphasia present

Answer 60

- A theory to try to explain how attitude influences behavior - An event triggers an attitude, and along with some outside knowledge we have of the subject, this will lead to a behavior Attitude: something that will influence our perception of an object Knowledge: that which regards appropriate behavior Example: Tommy's uncle has a heart attack, because he ate too many fattening foods; this event led Tommy to not eat fattening foods, beacuse his attitude toward them after this event, along with the knowledge that fattening foods can be bad for your heart, made him not eat fattening food anymore

Answer 61

Schema: describes a pattern of thought or behavior that organizes categories of information and the relationships among them. - How we make sense of the world around us - Use schemas as mental models by which we organize and interpret new information - Piaget's idea: cognitive development is all about building of schemas

Answer 62

- Define personality by looking at traits, i.e. defined as habitual _patterns of behavior_, thought, and emotion. According to this perspective, traits are aspects of personality that are relatively stable over time, differ across individuals (e.g. some people are outgoing whereas others are not), relatively consistent over situations, and influence behavior.

Answer 63

- The normal temperature of skin (between 86F and 97F) - This is how we judge temperature; by comparing it to physiological zero - Example: an object feels warm because it is higher than physiological zero

Answer 64

- When a baby's head is turned to the side, the arm on that side tends to straighten while the other one tends to curl - One of the primitive or neonatal reflexes - Lasts until 6 months of age

Answer 65

A certain behaviour is attributed to potential causes that appear at the same time. - Example: If our friend constantly cancels on us, then when they cancel again, we assume it's because that person is flaky and it has to do with their internal circumstances (self)/ disposition - We attribute the behavior to the person - Example: If our other friend is always nice, and smiling, and one day he's super angry when we order meatless pizza and there is bacon on it, we assume it's external or "situational" because usually he's very happy - We attribute the behavior to the situation Note: **consensus** can also affect this; for example, if many people are late to a meeting, vs. just one person, we attribute the lateness to the environment, since thats what can affect many people; thus, consensus makes us more likely to attribute something to the environment

Answer 66

- Include the reticular formation of the brain stem and parts of the thalamus that project axons into the cerebral cortex, diffusely - Release glutamate (excitatory neurotransmitter) into the cerebral cortex - This system is required for consciousness

Answer 67

- A psychological disorder in which individuals have at least one somatic symptom, which may or may not be linked to an underlying medical condition, and that is accompanied by disproprotionate concerns about its seriousness, devotion of an excessive amount of energy and time to it, or elevated levels of anxiety

Answer 68

- Patients learn to recognize negative thought patterns and develop more positive thought patterns to and coping behaviors - Learn to anticipate problematic situations, like going to a party where that drug will be available - Learn to self-monitor for cravings so they can apply coping strategies early - Research shows that the skills learned in CBT last longer than the therapy itself

Answer 69

- If we think that we will be met with public acceptance, we are happy not to conform to some norm - However, if we think this lack of conformity will be met with shunning, we are much more likely to go along with the group

Answer 70

Activist: focused on changing some aspect of society Reactionary: actively trying to resist change

Answer 71

- Adaptation: down regulation of the response; for example, if you put your hand on a table, initially you will feel pressure but that will go away - Amplification: a given signal is amplifed by a pathway, for example, a lay right may activate one cell, which subsequently activates many cells

Answer 72

- The motor cortex of the frontal lobe and the somatosensory cortex of the parietal lobe sit right next to each other and form the sensorimotor cortex - Important since the somatosensory cortex is involved in sensation and the motor cortex is involved in movement - Example: if we feel something hot, we better move our hand quickly

Answer 73

- A number of nuclei located throughout the brainstem (in the midbrain, pons and medulla) - Project into the cerebral cortex and release serotonin, diffusely

Answer 74

- Behavior that is genetically programmed; subject to change only through genetic change (mutation and recombination) - Seen in all individuals regardless of environment or experience Characteristics of Innate Behaviors: - _Inherited_: innate behaviors are encoded by DNA and passed on to children - _Intrinsic_: innate behaviors are present in an animal even if it were to be raised in isolation - _Stereotypic_: performed the same way each time - _Inflexible_: not modified by experience - _Consummate_: fully developed the first time they occur

Answer 75

- If we feel connected to a group then we are more liekly to conform; however, if we feel no connection to a group, we feel less of a need to go along with what that group is doing

Answer 76

- Penetrating stare - Eyelids tensed - Lips pressed together

Answer 77

- A defense mechanism; an unconscious process in which undesirable thoughts that may be coming into our consciousness are pushed into our unconsciousness

Answer 78

- Males: tend to be taller, stronger, more popular, self-assured and indpendent but are also more likely to engage in deliquent activities and alcohol use - Females: Typically the focus of teasing and sometimes sexual harassment, out of sync with their friends (in terms of interests)

Answer 79

- A hallucinogen combined with amphetamine - Causes Increases HR, BP, blurry vision, sweating nausea and hyperthermia - Psychologically causes feelings of euphoria, increased alertness, and overwhelming sense of well-being and connectedness and seeing things that aren't there - Stimulates the CNS but also increases dopamine and serotinin

Answer 80

- Aversive control: desscribes sitauations in which a behavior is motivated by the threat of something unpleasant - Types: escape learning or avoidance learning

Answer 81

Gray Matter - Contains most of the neuron somas White matter - Myelinated axons - In the brain, gray matter is on the outside, while white matter is on the inside - In the spinal cord, white matter is on the outside while gray matter is on the inside

Answer 82

- First neurons is short and synpases close to the spinal cord in the sympathetic chain (a set of ganglia close to the spinal cord) - Second neuron is long and synpases at the target cell - The neurons for the sympathetic nervous system are all dervied from the more middle portion of the spinal cord

Answer 83

- A degenerative brain disorder thought to be linked to a loss of acetylcholine neurons that link to the hippocampus; cerebral cortex, because of loss of neurons, shrinks in size - Marked by progressive dementia (a loss of cognitive function) and memory loss - Loss of recent memories usually occur before distant memories - Microscopic findings include neurofibrillary tangles and β-amylyoid plaques - Symptoms: memory, attention, planning, semantic memory, abstract thinking and later language difficulties and perhaps loss of control of bodiy functions

Answer 84

A metaphor used to represent an invisible barrier that keeps a given demographic (typically applied to minorities or women) from rising beyond a certain level in a hierarchy

Answer 85

- A method of experimental ablation - Can destroy tissue on the surface and deep into the brain - Wire is inserted into an area of the brain; a high frequency will then be applied to the wire, which will then heat up and destroy the tissue near the wire tip - Issue: will destroy everything in that area, both the neurons with cell bodies in the area as well as distant cells that have axons passing through the area - Makes it hard to determine if this was the area responsible for a behavior or if that behavior is controlled distantly and the route was just destroyed

Answer 86

- Tendency to focus on information that fits an individual's beliefs while rejection information that goes against them Example: in an election, you would be engaging in confirmation bias, if you only read stories about how wonderful the candidate is that you want to vote for

Answer 87

The actor-observer bias is an attributional bias that describes the tendency to attribute one's own actions to external factors but the actions of others to internal factors

Answer 88

Both - Nature: - Identical wins commonly start walking on the same day - Blind children will develop motor skills in the same order (so they can't be learning them from their parents by seeing and repeating) - Children everywhere develop these milestones in a given order - Environment - More space for children to practice and more stimulation so that they are curious and want to use the muscles, can influence the pace at which a child develops (this pace doesn't matter in the long term, however)

Answer 89

- Expectations - Experiences - Motivation - Altertness Example: text message - Expectations: whether or not we're expecting a text - Experience: do we know what the phone text message sound (or vibration) sounds/feels like - Motivation: text someone who we are interested in going on a date with; we are expecting a text but also very motivated to get the response - Alertness: much more likely to notice it when awake then drowsy

Answer 90

When something is recognized by our sense of touch for long period of time, for example, temperature, the nerves become saturated and do not fire as much and thus we adapt to the sensation Example: when you first go into a hot tub, it may feel very hot, but then it starts to feel more manageable

Answer 91

- A mechanism to store working memory into long term memory, by considering the new information in regard to how it relates to you - Example: if you're learning about history, you could imagine how a conversation with a general might go; involves a lot of deep processing and enhances the chances you might remember it - Related concept: **preparing to teach**: if we learn something in a way that we would later teach it, we put a lot of effort into organizing it and making sure we understand it, which enhances our memory of it

Answer 92

- Claimed 7 factors of intelligence: word fluency, verbal comprehension, spatial reasoning, perceptual speed, numerical ability, inductive reasoning, and memory - Makes sense; we could be strong in one and weak in the other - Issue with this theory: people who tend to do well on one of these factors, tend to do well on the other factors too (so more 1 general type of intelligence) - Issue: ignores non-academic intelligence - Developed by L. L. Thurnstone

Answer 93

- All the information in the environment goes into the sensory register, which briefly registers or stores all the sensory input you get (words, clicks, sirens, basically everything) - This input gets transfered to the selective filter right away, whic identifies what it is supposed to be attending to via basic physical characteristics (for language, the selective filter identifies voice, speed, accent, etc.) - Everything else gets filtered out - The selected information moves along to be perceptually processed, such that meaning is provided to the information (that the pitch is one that belongs to your mother, for example) - Then you can engage in other congnitive processes, like how to respond Issues: - If you filter out information before it gets meaning, you wouldn't be able to identify your own name when it's spoken in a cocktail party

Answer 94

- Standards for what is acceptable and what is not acceptable heavior - These are unwritten rules of how people should behave in a certain situation, around a certain group of people - The rules are defined by that group of people and are usually some type of moral standard or ethical value that is easily understood and internalized by all members of that group - Four distinct groups of norms: taboo, folkways, mores, and laws - Example: At a basketball game, your team wins and you stand up and yell loudly; this is acceptable within this situation and among these people and even encourage; however, if you are at a meeting at work, and engage in this same behavior, in this context, with this group of individuals, the behavior is not acceptable and normal - Note: norms vary culture to culture and can change over time Example: When baseball started, men only were allowed to play; but when men left for WWII, women started to play in order to keep people entertained; thus, this behavior went from being not acceptable to being acceptable

Answer 95

- The idea that a person's beliefs, values, and practices should be understood based on that person's own culture, rather than be judged against the criteria of another - Example: If someone is eating bugs, we should see how eating bugs fits into his culture and how his own culture views this, rather than looking at it from the perspective of our own culture (ethnocentrism)

Answer 96

- Involved in detection and regulation of body temperature - In addition, TRPV1 provides a sensation of scalding heat and pain (nociception). - Function, temperature: when there is a change in temperature, there is a subsequent change in the conformation of the protein - Function: When nearby cells get lysed, they release signaling molecules which can bind TRPV1 and causes the same conformational change - This sends a signal to the brain that via fast (Aβ) fibers, medium (Aδ fibers) and slow (C fibers)

Answer 97

- A condition characterized by lack of voluntary control over the onset of sleep - People randomly become drowsy and can fall into REM sleep for periods of usually 5 minutes - Genetically linked to loss or decrease in a particular neurotransmitter that is associated with alertness - Thus, neurochemical modulation may help people overcome this condition

Answer 98

- Process of renovation of deteriorated urban neighborhoods by means of the influx of more affluent residents - A form of urban renewal - However, while this provides a new and nice place for people to live, this often pushes the people still living there out, since they can no longer afford the prices of housing

Answer 99

- If a food they like begins to make them sick, they will stop eating it - If a drug they like begins to make them sick, they will still continue to eat it - This shows us how drugs can alter a rational mind

Answer 100

- A type of economy - Motivated by what benefits the society as a whole, and features common ownership of production that focuses on human needs and economic demand - Treats large industries as collective, shared businesses and compensation is provided based on the work contribution of each individual into the system

Answer 101

- This was the study that indicated that contact comfort and not the ability of nourishment that underlies why babies attach to their parents - In this experiment, baby monkies were taken from their parents and put in a cage with two psuedo-mothers: one mother was a fake monkey head on top of a wire cage body, that had milk, and the other was a cloth covered body, with a fake monkey head and no milk - The baby monkies preferred the cloth fake mother over the wire one that provided nourishment; and when they had to eat, would even try to hold onto the cloth mother while getting food from the wire mother

Answer 102

**ICD-10** - International Classification of Diseases, 10th Revision - Created by WHO - Has 11 top-level categories **DSM-5** - Diagnostic and Statistical Manual of Mental Disorders - Created by the American Psychiatric Association - Has 20 top-level categories - Classification scheme is not based on theories of etiology (cause) or treatments of different disorders; rather, it's based on descriptions of symptoms

Answer 103

**Increase in myelination** - this leads to faster communication between neurons and thus faster communication between brain areas - this may be why adolescents can process information faster than children **Synpatic Pruning** - Increase in brain volume during early adolescence, which shrinks during late adolescence - Develops many pathways and then gets rid of the ones it doesn't need so it can focus on strengthening the important ones

Answer 104

- Respond to pain and temperature

Answer 105

A _neurotic type of defense mechanism_, in which we figure out a way of making an excuse and convincing ourselves that we were not at fault - Often times, this includes thought processes with false logic or false reasoning - Useful because we avoid blaming ourselves

Answer 106

- We are more liekly to conform if there is a unanimous opinon in the group - Example: in a variant of the Asch line studies, rather than all the others giving one wrong answer, the participant had a supporter, who gave the right answer before the participants turn; and with this one person giving the right answer, it changed the liklihood of the participant conforming or giving the answer he believed to be right

Answer 107

Elementary Mental Functions: - Attention, Sensation, Perception, Memory - The intereaction with a more knowledgable other (MKO) with someone who thinks in elementary mental functions (such as a child), leads to learning and development of higher order mental functions

Answer 108

The perception of nonexistant edges in figures, based on surrounding visual cues Image: see the triangle even though there are non-existant edges that are required to see this image

Answer 109

- Refers to switching from one position to another without a change in social status. In order words, it's when we change our positions within our same level of social status, and we do not move up or down the social hierarchy. - Example: a middle-clas man working as an accoutant at one company, but then moves to another company where he is still an accoutant at the same level of seniority, then he has experiened horizontal mobility

Answer 110

The vascular layer of the eye, containing connective tissues, and lying between the retina and the sclera - Is pigmented black

Answer 111

- Dreams are caused by widespread, random activation of neural circuitry - This activation can miminic incoming sensory information and may also consist of pieces of stores memories, current and previous desires, met and unmet needs, and other experiences - Cortex tries to stitch this unrelated information together, resulting in a bizarre but familar dream - This is an activation of the brainstem and synthesis of this activation by the cortex (thus, activation-synthesis)

Answer 209

- **Trial-and-Error**: various solutions are tried until one is found that seems to work; while an educated approach may be used, usually only works when there are relatively few possible solutions - **Algorithms**: A formula or porecedure for solving a certain type of problem; can be mathetmatical or a set of structions, designed to automaticaaly produce the desired solution - **Deductive (top-down) reasoning**: starts from a set of general rules and draws conclusions from the information given (like a logic puzzle) - **Inductive (bottom-up) Reasoning**: seeks to create a theory via generalizations; starts with specific instances and then draws a conclusion from them **- Heuristics**

Answer 210

- The ability to to simultaneously analyze and combine information regarding color, shape and motion

Answer 211

The lawstates that the change in a stimulus that will be just noticeable is a constant ratio of the original stimulus. **ΔI/I = k** ΔI: represents the difference threshold I: represents the initital stimulus k= the ratio, which is constant _Example:_ If we hold a 5lb weight, and as we increase the weight, we notice the difference for the first time when the weight equals 5.5lbs, then (5.5-5)/5=0.1 ΔI=5.5-5 I= 5 k=0.1

Answer 212

- If we are given false information after remembering something but before retrieving it, the false information can affect the memory - For example: if we see a video with a car stopping at a yield sign, and then are told a story about the video, including how the car stopped at a stop sign, we may believe we saw a stop sign and remember the car stopping at a stop sign

Answer 215

- Individuals who have been adopted are compared to their adopted families and their biological families - Genetic: the trait will mimic what is seen in their biological family - Enviornmental: the trait will be similar to their adopted family

Answer 216

- **TRPV1 receptor** is activated - Change in temperature or molecules from lysed cells cause a change in conformation of the TRPV1 protein, which sends a signal down fast, medium and slow fibers **Fast: Aβ fibers** - Large fibers (decreased resistance) with lots of myelin (increased insulation); causes retraction of the hand **Medium: Aδ fibers** **-** Medium sized fibers with less myelin than the large fibers; causes the immediate sense of pain after hand retraction **Small: C fibers** - Thin and unmyelinated; causes the lingering pain minutes to hours after touching the stove

Answer 217

- Small societies are held together by their similarities and their independence; the individual was self-sufficient (each farmer owns his own land and grows food just for himself and his family) - Via _population growth in a small space_, the small society grows large and the structure of the society changes - Large societies have individuals that are dependent on each other; there isnt enough land for each person to make enogh food for themselves, so now some people become farmers and grows the food on a big piece of land for everyone and the others take on roles like teachers and tailors - Everyone becomes dependent on each other, which ensures that the community won't fall apart - Institutions then manage this interdepedence, and only change slightly to make sure that the interdependence remains stable

Answer 218

- A 2 year period of sexual maturation, during which time a person becomes capable of reproduction Males: Age 13 Females: Age 11 - For males, the major landmark that occurs during puberty is their first ejaculation, which occurs as a nocturnal emission - For females, the major landmark that occurs during puberty is their first menstrual cycle

Answer 219

After the study, most participants knew they had given wrong answers, but: - did not want to be ridiculed by the others (**normative social influence**: altering behaviors so we fit in better with those around us) - doubted their own responses; if everyone else has the same answer, that must be the right one (**informational social influence**: change our behavior because we assume others are more informed) - really, truly believed that they said the right answers (**perceptual error**)

Answer 223

At the part of the retina where the optic nerve connects, there are no photoreceptors in that area, so we have a blind spot

Answer 224

- Cognitive and physiological components of emotion occur simultaneously and result in the behavioral component of emotion, or action - Thus an event leads to both a physiological response and an emotion - They believed this because one, emotions come on quickly, so they cannot be a response to a physiological change (that would take too long) and because many emotions are accompanied by similar physiological changes (many emotions are associated with an increase in HR)

Answer 225

One that is given involuntarity, due to such factors as race, ethnicity, gender, and family background - It is a position that is neither earned nor chosen but assigned - These rigid social designators remain fixed throughout an individual's life and are inseparable from the positive or negative stereotypes that are linked with one's ascribed statuses. Example: A person born into a wealthy family has a high ascribed status based solely on the social networks and economic advantages that one gains from being born into a family with more resources than others.

Answer 226

- Working memory enables us to keep a few pieces of information in our consciousness simulataneously and to manipulate that information - Whatever we are thinking about at this moment - Visual and spatial information is processed in the **visuo-spatial sketchpad** (images or maps) - Verbal information is processed in the p**honological loop** (numbers and words) - The **central executive** allows us to conect these two places and to process verbal and visual/spataial information at the same time (for example if we're looking at a map with numbers and words) - This creates a **episodic buffer** (the combination of all things) which is the predecessor to long-term memory - Can hold 7 ±2 pieces of information at a time

Answer 227

- The bias in which society places emphasis on the most recent actions rather - Example: If you are are consistently a good soccer player, but in the most recent game, you played terrible, then people may think that you're not actually as good of a soccer player as you are

Answer 234

- Primary cortex: perform basic motor or sensory functions - Association cortex: associating different types of information to perform more complex functions Example - Primary motor cortex: primary motor cortex is to generate neural impulses that control the execution of movemen - Association motor cortex: responsible for transforming multisensory information into motor commands and for some aspects of motor planning

Answer 235

- First neuron is very long - Synpapses at a ganglion in the periphery with a second, much shorter, neuron which synpases with the target cell - Parasympathetic neurons start either in the brain stem or at the bottom of the spinal nerve

Answer 236

- Odor molecule binds to GPCR an oflactory nerve located within olfactory epithelium - G protein binds to an ion channel and opens it - Positive ions flow in and depolarize the cell - Triggers an action potential, via an axon which moves through the cribiform plate and synpases in the glomerulus - Mitral or tufted cells pick up on this signal - Send this signal to the brain

- Any cognitive or perceptual process that is distorted by the need to maintain and enhance self-esteem, or the tendency to perceiveoneself in an overly favorable manner Example: When thinking about the people in WWII who commited horrible acts against the Jews, we think "I could never do anything like that." That is the self-serving bias; when put into the right situations, most of us world commit those acts. (We learned this from the Milgram studies)

Answer 241

**Retroactive interference**: when new information causes forgetting of old information - Information from the present day reaches back and makes us forget something we used to know **Proactive interference**: when old information is interfering with new learning

Answer 242

- Automatic processes: things we can do automatically, and thus can multitask while doing them (like driving a car and eating) - Controlled processes: processes we would be unable to do without our full, undivided attention - The difference between whether something is an automatic or controlled process is how much we've practiced them; the more practice, the easier it becomes to do it automatically

Answer 243

- A multidisciplinary, macro-scale approach to world history and social change which emphasizes the world-system (and not nation states) as the primary (but not exclusive) unit of social analysis - Divides the world into three regions: core countries, periphery countries and semi-periphery countries **Core countries**: have a strong central government with enough tax to support it; economically diversified, industrialized, and relatively independent of outside control; big middle classes; focus on production of higher scope materials rather than production of raw materials Examples: Western Europe and U.S. **Periphery countries**: tend to have a relatively weak government; depend on one type of economic activity (usually); high percentage of poor and uneducated people and a small upper class which controls most of the economy; greatly influenced by core countries and transnational companies Examples: Latin America **Semi-periphery countries**: not dominant in international trade, but have a relatively diversified and developed economy Examples: India and Brazil

Answer 247

Reality is often reduced to be as regular, simple and symmetric as possible Image: we break this image into 5 circles, rather than into odd shapes; we're looking at a complex set of lines but rather reduce it to 5 circles

Answer 248

- When we move, the endolymph inside the semi-circular canals moves with regard to the plane, which allows us to sense what plane our head is rotating is along - We are also sensitive to how much of the endolymph is moving and how quickly, allowing us to gain information about the strength of the rotation

Answer 249

- A theory to try to explain how behavior influences attitude - In this phenomenon, a small request is made, and after gaining compliance, a larger request is made Note: this is the basis for how people are brainwashed; they begin to do small things for an authority figure they dislike, but over time, seeing those around them doing these small things and getting privileges from that authority, they think these small thing are ok; then those things become bigger and bigger - Thus, a small behavior eventually changes our attitude toward this behavior

Answer 250

- Deep connections allow us confide those painful or difficult feelings to others - Allow us to feel that we are not alone in those feelings and can lead to us feeling like we have control and can make us feel optimistic - Good social networks are also associated with eating well, exercise and sleeping patterns

Answer 251

- If you are a regular drug user, the body tries to counteract the drug use even before you ingest/inject the drugs - For example, if you are utilizing a stimulant, and do so regularly, the body will begin to recognize the situation in which that stimulant will be utilzed and begin to oppose the stimulant before it has entered the body, by, for example, lowering the HR, lowering the BP, etc. - If then you do not take the drug, your body has already done all of the stimulant-opposite events, so then you crash - Note: if you take the drugs in a new place, or in a new way and your body doesn't recognize this, it cannot counteract the stimulant and this can lead to an overdose since you're taking the same dose of drug but without your body impeding it

Answer 252

- Cocaine inhibits the reuptake of serotonin, dopamine and norepinephrine in the brain - Increases HR, BP, creates hypervigilance, alertness, etc. - Regular cocaine users may experience emotional disturbances, suspicion, cardiac arrest or respiratory failure

Answer 253

A type of norm that is widely observed, based on some moral value or belief - Since there is a strong understanding of mores, there is a strong reaction if the mores is violated - Do not always have serious consequences Example: everyone should be trutful; if a politican lies, then this is usually met with outrage

Answer 256

- The process by which the oocyte divides without growing - The first division is what takes the zygote and turns it into an embryo

Answer 257

- Economic benefit of having more children: more children means more people to support the parents; also, in places like Japan, the government incentivizes having more children since the birth rate is so low - Religion: many religions encourage large families in order for the religion to have a stronger following; many also prohibit contraceptives - Cultural benefits: having many children means that a person is passing down their own traits and values; there is also a prestige that comes with having kids

Answer 258

- A theory to try to explain how behavior influences attitude - We role-play and "fake" behaviors until it starts to affect our attitudes - For example: the first few days after having a baby, a woman may role-play the role of a mother; but after a few days, the mother takes on this role and it starts to feel more and more like her; this fits our attiude - We have changed our attitude toward that role, by initially changing our behaviors in order to play a specific role

Answer 259

- The right-hemisphere pays attention to whats going on both sides of the body and the environment - The left-hemisphere only pays attention to what is going on on the right side of the body and the environment

Answer 260

- If a skeletal muscle is rapidly stretched, the muscle will contract, presumably as a protective response, so that the muscle will not be injured by being stretched quickly - This happens because there are _muscle spindles_ in skeletal muscle, receptors which recognize stretch, since the spindle gets streteched along with the muscle stretching - Axons wrapped around these muscle spindles can detect the stretch and send that information back to the CNS - This nerve synpases and sends an excitatory signal to another nerve (whose soma is in the CNS), and this second nerve will synpase onto the muscle and excite skeletal muscle in that area **Knee-Jerk Response** - Below the knee, there is a tendon which connects to the bones of the lower leg; when you hit it, it streteches the muscles of the thigh (like the quadriceps), which then contract in response

Answer 261

Photopic vision is the vision of the eye under well-lit conditions - photopic visionallows color perception, mediated by cone cells, and a significantly higher visual acuity and temporal resolution than available with scotopic vision

- Where the sound wave moves into after being directed there by the outer part of the ear (pinna/auricle) - Also known as the external acoustic meatus

Answer 265

- Mainly used to detect pheromones, chemical messengers that carry information between individuals of the same species - An accessory olfactory system which contains sensory neurons that detect chemical stimuli - A axons from these sensory neurons project to the accessory olfactory bulb - All axons will synpase onto a location known as a glomerulus in th accessory olfactory bulb - Neuron -\> Glomerulus -\> mitral/tufted cell -\> Amygdala - Thus, by responding to extracelluar cues (pheromones), we will create a behavioral response in the animal - Note: humans have a vomeronasal organ, but do not have an accessory olfactory bulb, so we rely very little on pheromones

Answer 266

- Assumes that there are biological, psychological and social components to an individual's disorder - Biological component: genes, issues with neurons, etc. - Psychological: thoughts, emotions, or behaviors - Social: results from the individual's surroundings and can include issues of perceieved class in society and even discrimination or stigmatization

Answer 267

Answer 268

Focus on one part of the sensory enivornment while ignoring the others - Exogenous cues: external to any goals we have ourselves; we don't have to tell ourselves to pay attention (include things like bright colors, loud noises, etc. ) - Endogenous cues: require internal knowledge to follow the in the first place and require the intention to follow it (example: if you didn't know what an arrow meant, you wouldn't know to follow it and look at where it is pointing)

Answer 269

- Collections of axons within the white matter that are traveling together (starting at a similar area and heading to a similar area) - Often carry similar information from one part of the CNS to another part of the CNS

Answer 270

- Focuses completely on institutions with little regard with the importance to the individual; the inividual is acknowledged but nothing they do affects the structures of society - Also largely unable to explain social change and conflict; functionalism is focused on the equilibrium of the society so no change is possible - Structures of the society only change slightly so that equilibrium is met again

Answer 271

- Language is the main method by which information is transmitted from adults (more knowledgable others) to children - For children, it's a powerful tool of adaptation - Children engage in internal speech, speaking outloud to oneself, which is a way for children to plan and is thus an accelerator for thinking thinking and understanding

Answer 272

Also known as the auricle - The cartilaginous outside part of the ear - First place that a soundwave will hit

Answer 273

- Middle of the cerebellum coordinates movements that occur along the midline, like the torso and walking - The peripheral parts of the cerebellum coordiate limb movements (when they are being used individually, not as in walking) - Many parts of the cerebellum coordinate the muscles involved in speech; damage to the cerebellum can lead to issues with pronunciation and enuciation - Many parts of the cerebellum are also involved in eye movement

Answer 274

1. Mastery of experience: if we've done something before and succeeded, our sense of self-efficacy will be strengthened 2. Social modeling: Seeing people similar to ourselves successfully master a task, makes us believe we can do it too 3. Social persuasion: When people say something positive and encouraging, we are more likely to believe we can achieve a goal 4. Psychological responses: By learning to minimize stress and elevate mood in a situation that was previously nerve-wrecking or stressful, we can enhance self-efficacy

Answer 276

- Psychoanalytic theory of personality states that that our childhood experiences and unconscious desires affect our personality - Libido, or an natural energy, which fuels the mechanism of the mind; if this libidinal energy is stuck or fixed at various stages of psychosocial development, conflicts occur that can have lifelong effects - Fixation at a particular stage is what affects adult personality _Stages:_ - Oral stage (0 to 1 year): - Anal stage (1 to 3 years) - Phallic/Oedipal stage (3 to 5 years) - Latency: once libido is sublimated, the child enter latency which lasts until puberty - Genital : begins in puberty and lasts through adulthood - Developed by Sigmund Freud

Answer 277

- A theory which describes how we make decisions under conditions of uncertainty - Example: we are driving and its foggy and we are stopped at a red light; at what point do we decide if the light is green * If the light is green and we say it's green, it's a **hit** * If the light is green and we say it's not, that's a **miss** * If the light is not green and we say it's green, that's a **false alarm** * If the light is not green and we say it's not green, that's a **correct rejection**

Answer 278

- The application of rational-choice theory to social interactions; the behavior of an individual in an interaction can be figured out by looking at the rewards vs. punishments for the behavior - Behavior is guided by self-interest (what is best for us) and interdependence (that we need each other to survive) - If an interaction is approved, then it is more likely to be repeated, as social approval is a reward - If an interaction leads to pusishment, then it is more likely to be avoided, as social disapproval is a type of punishment Assumptions: 1. People seek to maximize their profits (rewards) 2. Behavior that results in a reward is likely to be repeated; however, the more often that reward is availble, the less value that reward has 3. Interacts operate within social norms 4. We have access to the information we need in order to make rational decisions 5. Standards of interactions change over time; what is seen as a reward to one person can be seen as a punishment to another

Answer 281

- Psychoanalytic theory of personality states that that our childhood experiences and unconscious desires affect our personality **Id**: consistes of all the basic primal, inborn urges to survive and reproduce; demands immediate gratification - Unconscious **Ego**: involved in ouer perceptions, thoughts, and judgements; seeks long-term gratification oveer immediate gratification - Conscious and unconscious **Super-ego**: moral compass; develops around the age of 5; responds to our actions, pride at our accomplishments and guilt at our failures - Our conscience - Mostly unconscious, but some conscious

Answer 282

Drives: internal states of tension that activate particualr behaviors focused on goals - Thought to originate within an individual without requiring external factors to motivate mbehavior - Drives help humans survive by creating an uncomfortable state, ensuring motivation to eliminate this state Primary drives: include the need for food, water, and warmth and help us to sustain bodily processes in homeostasis

- Respond to stretch

Answer 286

- An area in the midbrain which sends projects to the cerebral cortex - Releases dopamine profusely into the cerebral cortex

Answer 287

- A way of studying society that focuses on the inequalities in different groups - Karl Marx proposed that a society where one group exploited another group, economically, would contain the seeds of its own destruction - There is a accepted state (thesis) that would create a reactive state (the antithesis) - Example: bourgeoise (the minority) owned the factories and exploited the proletariat (majority; workers) to do the work - **Thesis:** In a capitalist society, the accepted thesis was the the bourgeoise ran the factories while the working class provided the labor - **Antithesis**: The desire of the working class to change the way things were - Both of these cannot exist together as one group is happy and one group is dissatisfied with the status quo - **Synthesis**: the eventual compromise that arose from the struggle between the two groups; eventually becomes a thesis in its own right

Answer 288

- Stated that all of us have different traits, i.e. that we all have a subset of traits from this universal "list of traits and that we all have a different subset of these traits; he came up with 4,500 words to describe traits - From this 4,500, he defined three categories of traits: **Cardinal:** characteristics that direct most of a person's activities; dominant traits: influence the central and secondary traits **Central**: present to some degree in almost everyone; much more common and serve as the basic building blocks of most people's personality (Examples: honesty, shyness, sociability) **Secondary**: preferences or attitudes (Example: reluctance to eat meat; love for modern art)

Answer 289

- epithelial covering of the highly vascular embryonic placental villi, which invades the wall of the uterus to establish nutrient circulation between the embryo and the mother - The trophoblasts that are not part of the syncytiotrophoblasts are called cytotrophoblasts

Answer 291

- Immediate and clear learning or understanding that takes place without overt trial-and-error testing. Insight occurs in human learning when people recognize relationships (or make novel associations between objects or actions) that can help them solve new problems - An "ah-ha!" moment (for example, when you're trying to solve a complex math problem and all of a sudden, the solution comes to you)

Answer 292

- Groups that establish the terms by which individuals evaluate themselves - It becomes the individual's frame of reference and source for ordering his or her experiences, perceptions, cognition, and ideas of self Example: if we're applying to medical school, the reference group is other medical school candidates

Scapegoating may be conducted by individuals against individuals (e.g. "he did it, not me!"), individuals against groups (e.g., "I couldn't see anything because of all the tall people"), groups against individuals (e.g., "Jane was the reason our team didn't win"), and groups against groups

Answer 296

- We are more likely to conform when we feel or are made to feel insecure; makes us feel less comfortable about our own knowledge, which increases the likelihood that we are going to follow the judgements of others

Answer 297

Hair cells: have stereocilium on them, called kinocilium that are attached to other cilium via tip links - The tip links are attached to a K+ channel - As the kinocilum gets gets moved by the flowing endolymph, the tip links are stretched which causes the K+ channel to open - Intracellular K+ opens Ca2+ channels, so Ca2+ also flows in - These two ions cause depolarization of the cell and a subsequent action potential

Answer 298

Answer 300

- Position - Vibration - Fine touch - Pain - Temperature - Gross touch - Note: these stimuli in the head and neck will travel through nerves into cranial nerves and into the brain stem; from the periphery, the information will travel through nerves, into spinal nerves and into the spinal cord

Answer 301

- High frequency sounds activate hair cells that are closer to the beginning/base of the cochlea - Low frequency sounds activate hair cells that are closer to the apex/tip of the cochlea - In the auditory cortex, there are regions which respond to sounds with a given frequency, for example, an area that responds to sounds with a frequency of 0.5kHz - This is how we can hear, distinctly, a base drum and a bees wings at the same time

Answer 302

Disorders which ult of substance are brought about due to use, abuse, intoxication, or withdrawal of/from a drug Some of these disorders include: delirium, dementia, psychosis, mood, anxiety, sexual dysfunction and sleep

Answer 304

- When we are not consciously aware of things that happen in our visual field when our attention is directed elsewhere Example: can you tell where the closest fire extinguisher is? You've probably walked by one every day, but failed to notice it because attention was focused elsewhere; even though its an important tool for our survival in the case of a fire

Answer 305

- Capsaicin, the "spice" molecule in jalapenos binds to the TRPV1 receptor - This receptor is a sensory receptor that responds both to pain and to temperature; thus, it induces us to sweat since it triggers the response that a change in temperature would induce

Answer 306

**Change our environment**: work to make the object of temptation harder to get, while making other, better options easier to get **Operant Conditioning**: using positive or negative reinforcement to increase a good behavior or use punishment to decrease bad behaviors **Classical conditioning**: use classical conditioning to train ourselves; for example, if everytime we crave chocolate, we then give ourselves strawberries, over time we'll grow to crave strawberries when we want something sweet Note: Deprivation doesn't work; if we remove something completely, 1. we usaully want it more and two, it requires a lot of self control, ego depletion can occur and we can then fail at our goal more easily (like being on a diet and allowing yourself no sweets, rather than limited sweets)

Answer 308

- The tendency to put forth less effort when working on a group task, if the individual contributions aren't evaluated - To reduce social loafing, increase the "individual" component of something; for example, in a group project, give the group a grade, but also give grades to each individual in the project; or you can split up projects so each person has their own piece (then there's no real group project, but more a collection of individual projects that form a group project)

Hypothalamus - Amygdala - Thalamus - Hippocampus Think of a **Hippo** Wearing a **HAT**

Answer 310

- functional magnetic resonance imaging - Have the same structures that can be seen by the MRI, but can see which of these structures are active - Neurons that are firing a lot, require more oxygen than non-active neurons; by measuring the relative amounts of oxygenated to deoxygenated blood in the brain, we can figure out how active something is

Answer 311

G factor: a variable that summarizes positive correlations among different cognitive tasks, reflecting the fact that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks - Example: an individual who does well on verbal tests is likely to do well (relative to otheres in the general population) on math tests - Supports the theory that there is **one** general type of intelligence

Answer 317

- The idea that self control is a limited resource; that if you use a lot of self control, it will get used up and you will have less of it in the future - Tasks that deplete self control can have a negative influence on later, unrelated tasks Example: in a study, those asked not to eat the fresh-baked goods in front of them, gave up more quickly on an unrelated tedious task, than those who were allowed to eat the baked goods when they wanted

Answer 318

- Our tendency to infer the causes of other people's behaviors - Two parts: internal (dispositional) and external (situational) - External: a person is acting some way because of something about the situation that he/she is in - External has three things to consider: - Consistency: refers the consistent behavior of a person over time; does the person usually behave this way in this situation - Distinctiveness: refer to the extent to which a person engaes in similar behavior across a series of scenarios; if a peron's behavior varies in different scenarios, we are more likely to form a situational attribution to explain in - Consensus: do others behavior similarly in this situation If we can say "yes" to distinctiveness and consensus, then we can say the situation is having an effect on the person If we say yes to "consistency," then we know that the person acts consistently across situations and their behavior is not dependent on the situation Example: you go to the zoo with your best friend, and she dosn't like snakes, but takes the time to read about them and learn about them; the next day, you bring a snake to her house and she yells and runs out of the door; thus, the distinct situation, she acted differently than at at the zoo, but in a way that was in consensus with how a lot of people scared of snakes might act, thus we may attribute her behavior to the situation

Answer 319

Answer 320

- Urbanization refers to the population shift from rural to urban areas, "the gradual increase in the proportion of people living in urban areas", and the ways in which each society adapts to the change

Answer 321

- This is how we adjust to bright light, with changes in the pupil and with the sensitivity of the rods and cones - With bright light, the pupil constricts, to not damage the retina and the sensitivity of the rods and cones goes down, so with bright light, the eye is desensitized to light - With low light, the pupil dilates and the rods and cones synthesize more light sensitive molecules, so the eye becomes more sensitized to light, leading to an upregulation in sensitivity

Answer 322

- Cones are mostly centralized at the center of the retina in the fovea of the macula - Rods are more lateral to this region

Answer 323

- A type on conformity, where we do not only conform publicly with a behavior, but conform privately with it as well - The idea, belief of behavior has been integrated into our own set of ideas, beliefs or behaviors - This type on conformity is stronger than compliance or identification, since we won't stop doing it or believing in it when external circumstances have changed

Answer 342

**Oral**: slow; can take 30 min because it has to go through the GI tract and get absorbed into the blood **Inhalation**: faster; less than 10 seconds, becuase it can go directly into the brain **Intravenous Injection**: takes effect within seconds **Transdermal**: drug is absorbed via the skin (like a nictoine patch); drug has to be pretty potent and can be released into bloodstream over several hours **Intramuscular**: drug is put into the muscle instead of into the blood (intraveous injection) - Note: people are more likely to become dependent on drugs that take effect more quickly

Answer 343

- Uses magnetic fields and radiowaves - A person is put inside a machine with a strong magnetic field, which causes the atoms in the brain to align; a radiowave is the added to that field which disrupts the orientation of these atoms; as the atoms move back to align with the original plane, they emit a signal, which can then be recognized, as different types of atoms create different signals, to create an image - Gives us a detailed image of the structure of the brain, but cannot provide information about function

Answer 344

- Prefrontal cortex is responsible for language, information processing, higher order thinking (the things that make us human) - Thus, the prefrontal cortex allows us to consider our emotions and allows us to make decisions on how to act upon them - Example: when someone pushes you, the prefrontal cortex may allow you to think "no, violence is not the answer, walk away"

Answer 345

- Personality is a result of the interactions that occur between a person and their environment - Focuses on observable and measurable behaviors rather than mental or emotional behaviors - Theorists - Pavlov: Classical conditioning - Skinner: Operant conditioning

Answer 355

- As a stimulus is repeated, the stimulated neurons become more efficient at releasing their neurotransmitters and, at the same time, the receptor sites on the other side of the synpase increase, increasing receptor density - This is believed to be the neurophysiological basis of long-term memory and how learning occurs - This is aptly named; we know that the membrane potential of the post-synpatic neuron changes (i.e. ions rush in when stimulated), thus the strength of a synpase is a product of how a pre-synpatic impulse can impact the change of the membrane potential in the post-synpatic neuron

Answer 356

- How various forms of social stratification, such as class, race, sexual orientation, age, disability and gender, do not exist separately from each other but are complexly interwoven - This is important, because the intersection of these various forms of discrimination, there is this immense discrimination, which may place an indivdiual at extreme disadvantage within a society; in order to understand the level of discrimination faced by an individual, we have to understand each discrimination as well as the intersect of thse various forms of discrimination - Example: a black transgender woman may face discrimination from being black, from being a woman and from being transgendered and at the intersect, there is heavy discrimination - If we only consider the fact that she is a woman, then we won't understand the level of discrimination which she faces

Answer 357

Answer 361

Thick, fibrous and structural layer that covers most of the eye (except at the cornea)

Answer 362

Variable: includes variation Ratio: number of responses - Reinforcer is delivered after an averge number of correct responses has occurred **Example**: A *fixed-ratio* schedule would be a car sales man needing to sell 5 cars to get a bonus, and every 5 cars he gets that bonus - A ***variable-ratio*** schedule would be that he gets the first bonus after 5 cars, the second after 3 cars, the third after 7 cars, the fourth after 6 cars and the 5th after 4 cars; thus, on average, he is getting rewarded every 5 cars, but the interval at which these bonuses are received is varied Example of a true variable-ratio: slot machine

Answer 363

When a conditioned stimulus is presented alone, so that it no longer predicts the coming of the unconditioned stimulus, conditioned responding gradually stops For example: After Pavlov's dog was conditioned to salivate at the sound of a metronome, it eventually stopped salivating to the metronome after the metronome had been sounded repeatedly but no food came

Answer 366

- The presence of a crowd leads to arousal (nervous energy) - This increased arousal is a physiological effect, which allows us to perform simple tasks with higher accuracy, but new or complex tasks with more difficulty - Thus, if, for example, a speech is well rehersed, this arousal will make us perform better - However, if the speech is poorly rehersed, and reciting it is new and complicated, under this state of arousal, we will make more mistakes

Answer 367

**Primary appraisal**: the initial evaluation of the environment and the associated threat; focuses on the threat in the present situation - Three appraisal types: - _Irrelevant_: I see a threat but it's not directed to me - _Benign-positive:_ A small fish sees a larg fish, which could be seen as a threat, but this fish is actually going after a medium size fish which is trying to eat the small fish - _Stressful_: the stressor could be harmful or challenging; **if this is the case, we move onto secondary appraisal** - **Seconadary appraisal**: directed at evaluating wehtehr the organism can cope with the stress - Three appraisal types: _- Harm_: damaged caused by the event _- Threat_: potential for future damage _- Challenge_: potential to overcome and possibly benefit from the event (how can I overcome the stress)

Answer 368

Front stage: That part of the individual's performance which regularly functions in a general and fixed fashion we define the situation for those who observe the performance. Front, then, is the expressive equipment of a standard kind intentionally or unwittingly employed by the individual during his performance - During the front stage, the actor formally performs and adheres to conventions that have meaning to the audience.[9] It is a part of the dramaturgical performance that is consistent and contains generalized ways to explain the situation or role the actor is playing to the audience that observes it. The actor knows he or she is being watched and acts accordingly Back stage self: Where the performer can relax; he can drop his front, forgo speaking in his lines, and step out of character - When all is said and done, and the individual returns to the back stage, they feel such a sense of relief that they know the actions that would be condoned upon in the front stage are free to be expressed - All their actions are not to please anyone but their self in the backstage.

Answer 370

- describes the tendency for groups to make decisions that are more extreme than the individual ideas and inclinations of the members For this to happen, several factors must be present: - All views do not have the same influence; for a viewpoint to influence a group's final decision, it is shared by the majority of the group - _Confirmation Bias_: In discussions about the topic, arguments made tend to favor the majority view and criticism is directed at the minority view Example: We are training a dog as a group and we all think that using treats is a good tool; we then discuss this, praising using treats, arguing for the use of treats and chastising the use of shock collars; leaving the conversation, we will feel more confident than ever that treats are the best way to train a dog

Answer 371

A ridge on the cerebral cortex

Answer 372

- Particular nuclei in the front lobe that send diffuse projections up to a number of areas of the cerebral cortex - Release acetylcholine diffusely throughout the cerebral cortex

Answer 373

- Information from the left visual field hits the nasal portion of the left side of the eye and the temporal portion of the right side of the eye - The information recieved at the nasal portion travels down the optic nerve and crosses at the optic chiasm - The information received at the temporal portion travels down the optic nerve, but does not cross at the optic chiasm - Thus, the left visual field is processed by the right side of the brain - Vice versa for the right visual field

Answer 387

- This theory builds on the early and late theories, but eliminates the selective filter and replaces it with an attenuator - Our brains processes a lot of information and quickly, so this theory says that instead of selectively filtering information, we dim things we are not selectively listening to, but upon hearing information we want to focus on, we attenuate our previous focus and redirect focus to the new stimuli, dampening the initial stimulus

Answer 388

The left side of the brain controls the right side of the body and vice versa - True for almost all senses except for smell, which is ipsilateral

Answer 389

- When a person has an unrealistic evaluation of his or her personal appearance and attractiveness, usually directed toward a certain body part - Person sees nose, skin or stomach as ugly or even horrific, when it is actually normal in appearance - Individuals may have disrupted day-to-day lives because of this; may also seek many plastic surgeries

Answer 390

Answer 391

Concentrating on one aspect of the sensory environment with the exclusion of the other stimuli in the environment - Selective attention - Divided attention

Answer 392

- Examines the necessary structures that make up a society and how each part helps to keep the society stable (large scale perspective) - According to functionalism, society is heading toward an equilibrium between institutions and social facts - Institutions: schools, marriage, government, etc. - Social Facts: Ways of thinking and acting formed by society that existed before any one individual and will persist once any given individual is dead; has a coercive effect and we don't notice it until it's resisted against - Example: the law; its always there, but we only notice it when we break it; other examples are moral regulations, religious faiths - These things must work together to create a functional society

Answer 393

Our brain is able to accomodate with changes in proprioception - Example: if we put googles on someone, which flips the things they see around them, over time, the brain will adjust, and flip everything back to right side up, even with the goggles on

Answer 394

- Any violation of norms, rules or expectations within society and depends on the context, the group in which it occurs and location in the world (just like norms) - While ususally this word has a negative context, in sociology, it simply refers to any at that goes against social norms and can vary in severity (jay walking vs murder) Example: In the US, eating meat is seen as the normal behavior by the majority; thus, a vegetarian would be seen as a deviant

Answer 395

The ability to perform multiple tasks at the same time - While new or complex tasks require **controlled (effortful) processing**, where our complete attention is given to one type of stimulus, familar or routine actions can be performed with **automatic processing**, where the brain automatically does something (like driving) and allows you to perform other things at the same time

Answer 396

**More likely to be obedient** - closeness; the closer we are to the authority figure, the more likely we will be obedient - physical proximity; more likely to obey someone standing nearby than somone on the other side of the room - legitimacy: more likely to obey commands from a legitimate authority; for example, more likely to obey commands from the experimenter (Milgram study), if he was wearing a labcoat and carrying a clipboard - depersonalization: when the victim is made to seem less human, possibly through sterotypes or prejudices, people are less likely to object to acting against them - lack of defiance: we are more likely to be obedient, when we see those around us also being obedient **Less likely to be obedient** - Victim proximity: we less likely to do something harmful as an act of obedience if the person is sitting next to us, versus in another room (Example: in the Milgram study, the participant was less likely to be obedient if they had to physically pick up the learners hand and place it on the electrocuting device than if the person was in the other room)

Answer 397

- Three semicircular, interconnected tubes located in the innermost part of each ear, the inner ear - The three canals are the horizontal (or lateral), superior and posterior semicircular canals - Canals are all at right angles to each other (orthogonal, or x axis, y axis and z axis)

Answer 398

- Non-adapting neuron: during exposure to the stimulus, these neurons fire at a frequent rate - Slow-adapting neuron: will fire quickly at the beginning of the stimulus, but then slow down over time - Fast-adapting neuron: will fire quickly at the beginning of a stimulus and as well when the stimulus stops, but will not fire during the duration the stimulus

Answer 511

- An individual may feel less inclined to take action because of the presence of others in the group - The more people in the group, the less likely you are to help Diffusion of responsibility theory: a person is less likely to take responsibility for action or inaction when others are present. Considered a form of attribution, the individual assumes that others either are responsible for taking action or have already done so. Assumption of responsibility tends to decrease when the potential helping group is larger, resulting in little aiding behavior demonstrated by the bystander(s). - Example: someone has a slight knowledge of CPR, but since the group is so large, assumes there's a doctor nearby to help the unconscious individual; thus, responsibility diffuses through the group and explains the bystander effect

Answer 565

- Involves cateogirzing items on the basis of whether they fit the prototypical, sterotypical, or representative image of the category - For example: Linda is 31 years old, single, outspoken, and very bright. She majored in philosophy. As a student, she was deeply concerned with issues of discrimination and social justice, and also participated in anti-nuclear demonstrations - if asked if she more likely to be feminist bankteller or a bankteller, you probably would say feminist bankteller, because the other parts of her fit with how you think a feminist would act **Conjunction fallacy**: the probability of two events occurring together (in "conjunction") is always less than or equal to the probability of either one occurring alone; so its far more likely for her to be a bankteller alone than a feminist bankteller, even though our instincts tell us otherwise

Answer 566

**Hyperreflexia**: An increase in the muscle stretch reflex - This happens because the lower motor neurons have not been activated by the upper motor neurons reguarly, so they have increased their sensitivity to stimulation; when those muscle spindles send a signal of stretch via the afferent neurons, the lower motor neurons over-react and cause hyperreflexia **Clonus**: rhythmic contraction of antagonist muscles (muscles that have the opposite effect of the joint) - Probably just an extension of hyperreflexia; one muscle contracts quickly, streteching the other, which causes contraction of the opposing muscle, which then stretechs the first muscle, etc. **Hypertonia**: increased tone of skeletal muscles **Extensor Plantar Response**: Normally if you brush along the bottom of the foot, you should get flexion, but with upper motor neuron dysfunction, you get extension

- That our view of ourselves comes not only from our direct contemplation of our personal qualities, but also from our perceptions about how we are being percieved by others We think about: 1. How do I appear to others? 2. What must others think about me? 3. Revise how we think about ourselves - Note: this theory says that we are not influenced by the opinion of others, but rather how we _imagine_ others must think of us; thus, we develop our feelings of ourselves based on correct and incorrect assumptions Example: A teacher grades a paper harshly because she thinks the student is smart and wants to make sure the student meets his potential; when the student gets the paper back, he may think the teacher thought his paper wasn't good, and therefore, he thinks of himself as being a poor student in literature

Answer 581

- The theory that certain needs will yield a greater influence on our motivation than others - Includes a pyramid in which the most primitive, essential and important needs are at the base, and the highest level of the pyramid coressponds to self-actualization or the need to realize one's fullest potential - Those at the base of the pyramid are most essential and are highest priority and the ones superior to the base can only be met if the ones below it are met _Note_ - Bottom two levels: basic needs - Love: social need - Self-esteem: respect - Self-actualization: the level of maximum potential (we have met all other needs and this is the final one)

- Language determines thoughts **Weak linguistic determinism:** language influences thought; makes it easier or more common for us to think in certain ways depending on how our language is structured - Example: if we say "draw out a girl pushes a boy"; if you draw the girl on the left and boy on the right, your language is probably written left to right and vice versa **Strong linguistic determinism**: language determines thought, completely; also known as the Whorfian hypothesis - Suggests that our perception of relativity, the way that we think about the world, is completely determined by the conetect of language - Example: Inuit lanaguge has a wide variety of names for different types of snow, whereas the English language has very few; therefore, according to this theory, Inuits are better at discriminating subtleties between differnt types of snow than English speakers are

Answer 587

- Motor function and fluency of speech is retained but comprehension of speech is lost - Patients speak nonsensical sounds and inappropriate word combinations devoid of meaning; so they speak, but the words coming out are not comprehensible (sounds like random words being put together to make sentences)

Answer 588

- Spacing out things we want to remember Example: rather than cramming for a test by studying 5 hours immediately before the test so the information is "fresh," it's better to study for 1 hour each day in the 5 days leading up to the test; enhances long-term memory - The spaces in between allow us to recognize what we do actually know and what we don't actually know (immediately after studying something, it may seem simple, but then later, we realize we don't actually understand it as well)

Answer 589

- When we are spinning, the endolymph in the semi-circular canals relays that information to the brain - When we stop spinning, the endolymph is still moving, so we feel like we're still spinning even though we have stopped; this is the sensation of dizziness - When the fluid stops moving, this is when the dizziness stops - If we rotate in the opposite direction, to get the endolymph to spin oppositely, this "cancels out" the original movement of the endolymph and makes the dizziness stop more quickly

Answer 590

Answer 597

* Light comes into the eye and and hits the retina * Within the retina there are rods, which contain small discs * Within these discs are proteins known as rhodopsin, which contain molecules known as retinal * When light is no present, retinal is in 11-cis retinal conformation * When light hits the retinal, it changes it to trans-retinal, which changes the conformation of the rhodopsin protein * The associated protein, transducin, a GPCR * The alpha subunit of transducin binds to cGMP phosphodiesterase and activates it, decreasing the level of cGMP and increasing the level of GMP * cGMP is responsible for the opening of Na+ channels along the cell membrane, so when cGMP decreases, the channels close * As less Na+ comes in, the rod hyperpolarizes and turn off * This turns on the bipolar cell, which then, via a bunch of other cells, sends a neural imput to the brain

Answer 598

- Refers to the notion that culture takes time to catch up with technological innovations, and that social problems and conflicts are caused by this lag - Happens because material change occurs rapidly while non-material culture remains stable for long periods of time Example: When cars were first invented, there were no speed limits, no guidelines for right of way, no stop lights; eventually, non-material culture caught up and rules were written Example: How long it took for businesses to incorporate e-mail into their systems

- Source monitoring errors: involves confusion between semantic and episodic memory; have difficult with keeping tract where various information came from - This is the reason that misleading or false information can have such an impact on a memory - i.e. : we cannot differentiate between if we actually remember it or if we read it and and incorporated it into the memory

Answer 602

By the process by which we appraise and cope with a stressor which gives rise to a stress reaction

Answer 603

A state of consciousness in which we are awakre and able to think - In this state, we are able to perceive, process, access information and express that information verbally

Answer 604

- A stimulus first results in a physiological arousal, which leads to a secondary response in which the emotion in labeled - Emotions follow directly from bodily responses - Example: petting your dog - When petting your dog, different neurotransmitters are released, HR goes down, which is then interpreted as "happiness" - Its not petting the dog that makes you happy, its what the dog does to your body - Example: don't cry because you're sad, but are sad because you cry

Answer 605

- For 90% of right-handed people, language is centralized in the left half of the brain - For 70% of left-handed or ambidextrous people, language is still centralized in the left hemisphere of the brain

Answer 606

The ability to distinguish between two stimuli, learning to respond to some stimuli in a certain way, but not to others Example: We discriminate between loud sounds and do not respond to all of them in the same way; this is important, we do not want to respond to the loud yelling at a sports event in the same way we would respond to the loud yelling of people coming out of a burning building

Answer 607

- Controls sexual behavior - When the anterior hypothalamus is stimulated (in rats), they will mount almost anything - If there is damage to the anterior hypothalamus, there is permanent inhibition of sexual activity - Note: anterior hypothalamus also regulates _sleep_ and _body temperature_

Answer 608

- Disorder that make it difficult to fall asleep, stay a sleep or avoid sleep - Include insomnia, narcolepsy and sleep apnea

Answer 609

- - A theory to try to explain how attitude influences behavior - Focuses on why and how we are persuaded to act in a certain way - Information is processed in two ways: Central Route: the degree of attitude change depends on the quality of the arguments made by the persuader Peripheral Route: the degree to which something is persuasive is based on superficial and non-verbal cues, such as attractiveness, expertise or staus of the persuader Example: A pharmaceutical representative comes to us to sell us a new drug; we will evaluate the argument and the benefits and risks to the patient (central route), but also consider if the person is dressed well, and looks professional (peripheral route); this will ultimately shape our attitude and dictate our behavior, i.e. if we buy the drug or do not buy the drug - This is more of a cognitive model than the prototype willingness model or the theory of planned behavior

Answer 610

- **Weak Social Constructionism**: proposes that social constructs are dependent on brute facts, which are the basic and most fundamental and don't rely on any other facts - Brute facts differ from institutional facts, which are facts that rely on other facts (examples: money depends on paper which we have given value) - **Strong Social Constructionism**: the whole of reality is dependent on language and social habits, that all knowledge is a social construct and that there are no brute facts - Example: we created the idea of quarks as well as everything we use to explain it

Answer 611

- A collection of subcortical nuclei that function together - Serves an an important relay station or incoming sensory information, including all senses except smell - After receiving incoming sensory impulses, the thalamus sorts these impulses and transmits them to the appropriate areas of the cerebral cortex - Also important in cognition, emotion and consciousness because the thalamus is connected to many parts of the brain and is a key site where information passes through and which passes this information around

Answer 612

- Language is conditioned through operant conditioning; acquire language through reinforcement - Parents and caregivers repeate and reinforce sounds that sound most like the language spoken by the parents; thus over time, the infant perceives that certain sounds have little value and are not reinforced while certain sounds have value and are reinforced - Example: every time a child says something that sounds like "mama" the mother starts smiling, hugging the child, etc., so over time, the child learns the more they make the "mama" sounds, the more hugs and smiles I get

Answer 613

--We make our decsiions based on how easily similar instances can be imaged - Used when we try to decide how likely something is - Usually right, but sometimes wrong given that our most easily memorable experiences may not always be representative Example: is a shark attack or fire-work related death more common? We think about the times we hear about these things on the news and draw a conclusion - We might have read more about shark attacks and death, but its because fire-work related deaths are not as publicized, so the availbility heuristic may lead us astray

Answer 614

- Electroencephalography - Measure the electrical activity that is generated by neurons in the brain; look at the sum total electrical field that is generated by the brain - Produces waves which can be read to determine things like if people are asleep or awake or if someone is having a seizure - Place electrodes on someones scalp at predeteremined positions - Cannot tell us anything about the activity of a given neuron or groups of neurons, because they're external to the cells

Answer 615

- Believed that rewards and punishments (operant conditioning) to increase or decrease a behavior - Personality is, thus, the reflection of behaviors that have been reinforced over time

Answer 616

- Focuses on how the exponential growth of a population can outpace growth of food supply and lead to social degredation and disorder Malthusian catastrophe: the prediction that as third-world nations industrialize and undergo demographic transition, the pace at which the world population will grwoth is much faster than the ability to generate food and mass starvation will occur

Answer 618

- High quality healthcare facilities are more likely to exist in wealthier than poorer neighborhoods - Diseases are more likely to spread within crowded areas - Poverty is associated with a poor diet, which increases chances of morbidity (food deserts) - Individuals living in poverty are more likely to take jobs which pose substantial health risks (both dangerous conditions as well as conditions which pose a health risk, like mine workers, who can die from the mine collapsing, but can also get black lung disease) - Cannot afford healthcare - Note: racial differences exacerbate these issues, since minorities are less likely to get access to healthcare and are more likely to live in poverty

Answer 619

- A structure which passes through the middle of the cochlea - Contains two components: basilar membrane and tectorial membrane - The basilar membrane contains hair cells, which, which when they are moved by endolymph, create an electrical signal from the auditory stimulus which prompted the endolymph to move

Answer 620

- Medication either prevents the release or the re-uptake of dopamine to inhibit the reward signal from being propogated - Help reduce cravings, primarily

Answer 621

- a stimulus which initially produces no specific response other than focusing attention. - In classical conditioning, when used together with an unconditioned stimulus, the neutral stimulus becomes a conditioned stimulus - Something conditioned has to be learned Example: the bell initially did not make the dog drool, but when used together with food (the conditioned stimulus), which normally causes the dog to salivate, the neutral stimulus becomes a conditioned stimulus and the dog drools when he hears the bell

Answer 622

A clear, domelike window in the front of the eye, which gatehrs and focuses the incoming light - Serves to protect the front of the eye and to bend light (slightly)

Answer 623

Answer 625

- A social system in which your position in soceiety is detemined by to whom you are born and to whom you are married - Very little social mobillity in caste systems; limited to the social group within which you are born and are limited in mobility despite apptitude or achievements - However, this is very socially stable, since there is no movement between castes

Answer 626

- referred to at the hunger center because it has special receptors thought to detect when the body needs more food or fluids - lateral hypothalamus triggers eating and drinking - In rats, if this part is destroyed, they refuse to eat or drink and starve to death if not force-fed through tubes

Answer 627

- Red: also known as long, since they absorb long wavelength rays best (red: 700nm) - Green: also known as medium, since they absorb medium wavelength rays best (green: 520–560 nm) - Blue: also known as short, since they absort shorter wavelength rays best (blue: 400nm)

Answer 628

**Hyperglobalist**: sees globalization as a legitimate process; countries become interdepedent and their economies intertwined though theorists do not comment on whether this is good or bad **Skepticalist**: critical of globalization; considers these processes as becoming regionialized and not globalized; third world countries are not being integrated with the same benefits as first world countries; don't believe that the current economy is leading toward global capitalism; transnational companies are still bound to their home country and borders are as important as ever **Transformationalist**: do not comment on good or bad, but rather just comment on how things are changing; many factors that affect the new world patterns, but the outcomes of these changes is unknown

Answer 629

- is an inborn error of metabolism, due to a deficient liver enzyme, phenylanaline hydroxylase, that results in decreased metabolism of the amino acid phenylalanine - Genetically, it occurs in 1/15,000 babies - However, those babies are identified at birth, and feed a phenylalanine free diet, so they don't end up getting PKU and the neurological deficiencies that come along with this disease

Answer 630

**1. Wait until someone dies, then take a look** - Told scientists alot; allowed them to define structures of the brain and allowed them to take the brain apart and look at it from different angles - However, can't tell us anything about how the brain functions (controls body or generates thoughts) **2. Wait until something went wrong (and usually wait until they die to do an autopsy)** - Wait until someone had a brain injury and then studying the effects of the injury - Allowed scientists to determine "cerebral localization": the idea specific parts of the brain could control specific aspects of behavior, emotion, or thought - However, damage can occur to multiple parts of the brain, so its hard to isolate what spot is responsible for what change - Issue with both of these: the time-span over which this needs to take place, since the patient has to die, is very long and the lack of control of where injuries happen, make this limited in terms of research implications

Answer 631

- When the skin on the baby's back is stroked on one side, the baby will tend to move or swing toward that side - One of the primitive or neonatal reflexes - Disappears around 6 months

Answer 632

Non-associative learning: a relatively permanent change in the strength of response to a single stimulus due to repeated exposure to that stimulus Types: Sensitization or Habituation - Called non-associative, becuase there isn't a reward or punishment given for the change in response, its just a simple change in response (associative are things like classical and operant conditioning)

Answer 633

- Interferes with serotonin transmission which causes people to experience sensations that didn't actually come from the environment (hallucinations) - See things rather than hear things that aren't there - A hallucinogen

Answer 635

The cerebral cortex - The cerebellar cortex is the gray matter covering the cerebellum

Answer 636

**0-2 years: Sensorimotor stage** - Children gather information about the world through their senses - Learning how to move their bodies around as they use their senses; helps them to explore the world and learn what they are capable of **2-6/7: Preoperational stage** - think in images and symbols - begin to develop language - engage in pretend play - very egocentric: don't understand that other people might have a different perspective (a 5 year old might stand in your way watching tv, not understanding that you can't see because they can see just fine) **7-11: Concrete operational stage** - learn the idea of conservation (example if you take two glasses with equal amounts of water and pour pour one into a taller glass, the pre-operational child will say the tall glass has more water because its taller, but the operational child will say that they're the same because s/he can understand that the water is conserved) (see image) - mathematics ( will know something like 8+4=12, which means 12-4=8) **\>12 or older: Formal operational stage** - Reason about abstract concepts (what might occur); thus, learn about consequences - Moral reasoning

Answer 637

- A socioeconomic conditon in which people are poor in comparison to the larger population in which they live - This type of poverty is not saying that they do not have the basic resources, but that they are being excluded from parts of society because their income is too low - Usually defined to the median income in an area - If a countries income rises, the absolute poverty line does not change, but the relative poverty line does

Answer 638

Proteins/ Polypeptides (derived from amino acids) Steroid hormones (derived from cholesterol) Tyrosine derivatives - Thryoid hormones - Catecholamines

Answer 639

- **Reflexes** - **Orientation**: behaviors that allow us to orient ourselves spatially in our environment - Example: kinesis (orienting your body, for example when you fall); taxis (moving toward or away from a stimulus, like a bug going toward light) - **Fixed action patterns**: a sequence of coordinated movements that are performed without interruption (like reflexes, but with many movements) - Example: Graylag Goose. If an egg is displaced from the nest, the bird will reflexively roll the egg back to the nest with its beak. However, Konrad Lorenz discovered that it will complete this action even if the egg is removed during the behavior.

Answer 640

- A spherical structure located in the olfactory bulb of the brain where synapses form between the terminals of the olfactory nerve and the dendrites of mitral, periglomerular and tufted cells - Are the initial sites for synaptic processing of odor information coming from the nose - A given glomerulus will respond to one type of molecule, as all the cells responsive to a particular chemical will synpase onto the same glomerulus

37-42 weeks, with an average of 39 weeks - Before 37 weeks: pre-term - After 42 weeks: post-term

Answer 651

Discrimination between ingroups and outgroups is a matter of favoritism towards an ingroup and the absence of equivalent favoritism towards an outgroup - Outgroup derogation is the phenomenon in which an outgroup is perceived as being threatening to the members of an ingroup - This phenomenon often accompanies ingroup favoritism, as it requires one to have an affinity towards their ingroup - In this concept, we are nice to our in-group but can actually be mean to our outgroup (Different than in-group favoritism, where we are nice to our in-group, but neutral toward the out-group)

Answer 652

- Helps lower HR, BP and cholesterol

Answer 653

Objects that are perceived to be higher are perceived to be futher away than those that are lower - Monocular cue Example: the green rectangle is placed physically higher and therefore assumed to be further away; both the red and green rectangles are the same height

Answer 654

- As the syncytiotrophoblast projects continue to grow, created extended villi, all while maternal blood continues to pool near these structures - Eventually, fetal vessels are created within these villi; these vessels are close to maternal blood and nutrients and waste can pass between them - Note: the cytotrophoblasts, the unicellular form of the trophoblasts which does not create the majority of the villi (that's the syncytiotrophoblasts), line the villi, so that the maternal blood and fetal blood are not actually in contact

Answer 655

- A type of norm which dictates what behaviors are completely unacceptable under any circumstance - Engaging in taboos are usually punishable by law, but also commonly result in severe disgust of the society around that individual Example: incest and cannibalism

Answer 656

Answer 657

- Long tracts are collections of axons traveling a long distance through the CNS, often connecting the cerebrum to the spinal cord - While moving through cerebrum, they pass through the brain stem and make up some of the white matter in the brain stem - Two important tracts that pass through the brain stem: - Upper motor neurons (afferent) - Somatosensory long tracts (efferent)

Answer 658

Scientific and objective study of animal behaviour, usually with a focus on behaviour under natural conditions, and viewing behaviour as an evolutionarily adaptive trait - Focuses on looking at overt behavior (observable behvaiors): innate behavior, learned behavior, and complex behavior

Answer 659

- Schema: describes a pattern of thought or behavior that organizes categories of information and the relationships among them. - In order for us to develop schemas they have to grow and change via assimilation and accomodation **Assimilation**: the process of classifying new information into an existing schemata - Assimilation has 2 ss so remember as "same schema" **Accomodation**: the process by which existing schemata are modified to encompass this new information - Can accomodate by modifying previously existing schemas or by creating new ones - Accomodation has two ccs in it, so remember as "change or create"

Answer 660

- Genetically, monozygotic twins are 100% similar, while dizygotic twins and siblings are only 50% similar - However, environmentally, monozygotic and dizygotic twins share 100% similar enivornment, while siblings do not share the same environment - This is because siblings are raised at differnt types, by parents that have different levels of experience (based on 1st child vs 2nd child, etc.), and in a different time, so the experience for the child may be different than its siblings

Answer 661

**Fluid intelligence:** our ability to reason quickly and abstractly, such as when we're solving novel logical problems - Decreases as we move into older adulthood **Crystallized intelligence**: Our accumulated knowledge and verbal skills - Increases as we move into older adulthood (or stay the same)

Answer 662

- Self-aware - Caring - Wise - Interests are problem-centered; focus on a task that is the mission of their life - Have a higher purpose that is focused on larger causes and less focused on the basic aspects of life Note: self-actualization is rarely achieved

Answer 663

- The gate control theory of pain asserts that non-painful input closes the "gates" to painful input, which preventspain sensation from traveling to the central nervous system. Therefore, stimulation by non-noxious input is able to suppress pain. - There is a special "gating" mechanism that can turn pain signals on or off, affecting whether or not we perceive pain - In this theory, the psinal cord is able to preferentially forward the signals from other touch modalities (pressure, temperature) to the brain, thus reducing the sensation of pain - This is why when you hit your knee, rubbing the injury seems to reduce the pain

Answer 664

- Context-dependency effects on recall are typically interpreted as evidence that the characteristics of the environment are encoded as part of the memory trace and can be used to enhance retrieval of the other information in the trace. - In other words, you can recall more when the environments are similar in both the learning and recall phases. Example: A academic application would be that students may perform better on exams by studying in silence, because exams are usually done in silence.

Answer 665

- A syndrome associated with chronic alcohol use that arises as a product of deficiency of Thiamine (Vitamin B1) - Causes visionchanges, ataxia and impaired memory

Answer 666

- Responses are reinforced after a variable amount of time has passed Example: a car salesmen will get a bonus if he is speaking to a customer when his supervisor stops by; since hedoesn't know when the supervisor will drop by, to increase his chances at a bonus, he needs to be always talking to a customer - Rate of response with variable-interval is higher than with fixed-interval

Answer 667

**Hypothalamus** **Pituitary (also known as the master gland)** **Thyroid** - Produces T3 and T3 - Involved in metabolism **Parathryoid** - Produces PTH - Involved in calcium balance **Adrenal glands** - Cortex: cortisol and aldosterone - Medulla: catecholamines **Gonads** - Releases sex steroids **Pancreas** - Releases insulin and glucagon

Answer 668

- Microphone on the outside of the persons skull, which transmits sound into an electrical impluse - This signal is moved into the transmitter, which goes into the receiver, the first structure inside the skull - The receiver sends the signal down a stimulator, which then stimulates the cochlea, allowing the cochlea to transmit the sound into neural imputs

Answer 669

- Created the Asch line studies - Part of a group of scientists known as the Gestalt Scientists; believed that it was not possible to understand human psychology or human behavior by breaking it into parts - Was born in Warsaw Poland, to a jewish family, but moved to the U.S. in the 20s.

Answer 670

- A population shift from central urban areas into suburbs, resulting in the formation of (sub)urban sprawl - Sub-urbanization is inversely related to urbanization, which denotes a population shift from rural areas into urban centres - Issues: can be far from healthcare and jobs; but sometimes the sub-urban areas can create their own economic centers and fix these issues

Answer 671

A prediction that directly or indirectly causes itself to become true, by the very terms of the prophecy itself, due to positive feedback between belief and behavior - Example: If we see city dwellers as rude and start to not like them and avoid them, then they might think we are rude and not want to spend time with us; as a result of this, we percieve them to be more rude, and the positive feedback continues

Answer 672

- Gross motor skills develop before fine motor development (why we can sit up and walk before we can draw a picture) - Development occurs from head to toes (why we can sit up before we can walk)

Answer 673

- **Escape learning:** Also known as escape conditioning; when you perform a behavior to terminate an ongoing, unpleasant, aversive stimulus - "Get me the heck out of here" Example: Fire breaks out, we weren't expecting it, but we foudn the exit and escaped from the fire - Escape learning can be turned into avoidance learning of some type of signal occurs before the aversive stimulus is present **Avoidance learning**: individual learns a behavior or response to avoid a stressful or unpleasant situation Example: if the fire alarm goes off, we would make our way to the door and leave, and be long-gone by the time the fire actually breaks out

Answer 674

- Raise cheeks - Elevated corners of the mouth - Wrinkles on the outward corners of the eyes (sometimes)

Answer 676

- Regulates the autonomic nervous system - Does this by regulating the endocrine system, and regulating the amount of, for example, epinephrine

Answer 677

- A response which did not need to be taught; occurs naturally in reaction to the unconditioned stimulus. For example: if the smell of food is the unconditioned stimulus, the feeling of hunger in response to the smell of food is the unconditioned response - Thus, in an unconditioned response, a stimulus triggers an innate physiological response to the stimulus

Answer 678

- If we are provided misleading information, we can alter our memories to make more sense of the misleading information - Example: when watching a video of a car crash, and later being asked questions about the when one car "hit" the other (group 1) or when one car "smashed" into the other (group 2) and weeks later asking if there was glass on the ground, those that got the word hit remembered there was no glass on the ground (true), but those that got the word smashed remembered there was glass on the ground (false)

Answer 679

Cognitive dissonance: The discomfort we feel when holding two or more conflicting cognitions, such as ideas, beliefs, values or emotional reactions Example: I smoke and also know smoking causes cancer **1. May try to modify some of our cognitions** - Might say " I don't really smoke that much" **2. Trivialize: making less important** - Might say " The evidence is weak that smoking causes cancer" **3. Adding more cognitions** - "I exercise so much, that it doesn't matter that I smoke" (added an additional cognition about exercise) **4. Denying** " There is no evidence that smoking and cancer are linked"

Answer 680

- A status by which the a person is most identified and is pervasive in that person's life; generally how people view themselves and often holds symobolic value Example: if a woman feels that her role as a mother is more important than her role as a woman, a daughter, etc., she is more likely to identify herself as a mother and to identify with other women who label themselves as such. An individual's master status dominates how they are perceived by others and their behavior towards them.

Answer 681

- Conducted by Philip Zimbardo at Stanford in 1971 - Trying to determine how conformity and obedience can result in people behaving in ways that are counter to how they would act on their own and even counter how they think they would act Goal of study: to look at how social norms and social conventions might influence the behaviors of the particpants, who are playing the roles of the prisoners or guards Participants: no mental disorders, middle-class, males, university students - Randomly assigned to prisoner or guard via coin flip - Prisoners were "randomly" arrested, finger printed, photographed for a mug shot, and, put in uniform with chains on their ankles, taken to their cell, which had a mattress but no windows or clocks - Guards were told prior to the experiment not to physically harm the prisoners, but that they could use tactics to scare the prisoners; were given unifroms and batons Results are in image: - Note: none of the guards left the experiment

Answer 682
