(261 cards)
1
Q
Name the seven schools of psychology
A
- Structuralism
- Functionalism
- Psychodynamic Psychology
- Behaviorism
- Humanistic Psychology
- Cognitive Psychology
- Gestalt
2
Q
Structuralism
A
Wilhelm Wundt
Focused on understanding the conscious experience through introspection(the examination or observation of one’s own mental and emotional processes)
breaking down mental processes into the most basic components. Researchers tried to understand the basic elements of consciousness using a method known as introspection..
3
Q
Functionalism
A
William James
Functionalism focuses on understanding mental processes and behavior by examining their purpose or function in adapting to the environment. Instead of analyzing the structure of consciousness into its basic elements, as structuralism does, functionalism seeks to explore how mental processes help individuals adapt to their surroundings and fulfill their need
4
Q
Psychodynamic Psychology
A
Sigmund Freud, Erik Erikson
Focuses on the role of the unconscious thoughts, feelings, memories, and childhood experiences in shaping behavior
5
Q
Behaviorism
A
Ivan Pavlov, John B. Watson, B. F. Skinner
Focuses on observing and controlling behavior through what is observable
6
Q
Humanistic Psychology
A
Ulric Neisser, Noam Chomsky, Jean Piaget, Lev Vygotsky
emphasizes the study of human potential, personal growth, and the inherent value of individuals, focusing on subjective experiences and the role of free will in shaping behavior
7
Q
Gestalt Psychology
A
Looks at the human mind and behaviors as a whole
emphasizes the importance of perceiving and understanding the whole of an experience or phenomenon, rather than analyzing it into its individual components
exImagine you see a drawing of a circle, but a small section of the circle is missing or incomplete. Despite the gap in the circle, your brain tends to perceive it as a complete circle rather than a broken one. This ability to mentally fill in the missing parts and perceive an incomplete figure as a whole is an example of the Gestalt principle of closure
8
Q
Current theories
A
developmental, social, personality, abnormal, clinical, health
9
Q
What is a hypothesis?
A
Tentative and testable statement about the relationship between two or more
variables
Worded as an if-then statement
ex: If I study all night, then I will get a passing grade on a test
Bridges the gap between the realm of ideas and the real world
10
Q
What is a theory?
A
A well-developed set of ideas that propose an explanation for observed phenomena
11
Q
What is the relationship between a hypothesis and theory, and how do they fit into the scientific method?
A
Hypothesis are tested, theories are modified and refined to reflect and incorporate the results of the tests
12
Q
What is the Institutional Review Board (IRB)
A
Committee of administrators, scientists, and community members that reviews proposals for research involving human participants
Approval generally required to proceed with experiment
13
Q
Institutional Animal Care and Use Committee (IACUC)
A
Committee of administrators, scientists, veterinarians, and community members that review proposals for research involving non-human animals
Charged with ensuring experimental proposals require the humane treatment of animal subjects
Conducts semi-annual inspections of all animal facilities to ensure that research protocols are being followed
No animal research project can proceed without committee’s approval
14
Q
Deception
A
Purposely misleading experiment participants to maintain the integrity of the experiment, but not to the point to cause harm
15
Q
Debriefing
A
Informing participants, the complete and truthful information about an experiment at its conclusion
Only occurs when an experiment involves deception
16
Q
Informed consent
A
Process of informing a research participant about what to expect during an experiment, any risks involved, and the implications of the research, and then obtaining the person’s consent to participate
Also lets participants know their involvement is completely voluntary and can be discontinued without penalty at any time
Guarantees any data collected in the experiment will remain completely confidential
17
Q
What is descriptive or qualitative research?
A
Research studies that don’t test specific relationships between variables
Three main types:
1. Naturalistic observation
2. Case studies
3. Surveys
-Used to describe general or specific behaviors and attributes that are observed
-Sometimes difficult to form a hypothesis
Let’s say you’re interested in understanding how students experience stress during exam periods. If you were to use qualitative research:
You might conduct interviews with a small group of students to hear their personal stories and feelings.
You could observe students in their natural environment to see how they cope with stress.
You might analyze personal journals or reflective essays to gain insight into their thoughts.
In the end, instead of providing statistical data like “80% of students feel stressed during exams,” qualitative research might offer a more nuanced understanding of how and why students experience stress, exploring the emotions, coping mechanisms, and social contexts involved.
18
Q
What is correlational research?
A
Research investigating the relationship between two or more variables
-Formally tests whether a relationship exists between variables
-Can find a relationship between to variables but the only way to claim there even is a relationship is by performing an experiment
19
Q
What is experimental research?
A
A research method that uses hypothesis testing to make inferences about how one variable impacts and causes another
-Randomly assigns people to different conditions, using hypothesis testing to make inferences about how these conditions affect behavior
-Aims to determine if a variable directly impacts and causes one another
20
Q
What is naturalistic observation?
A
(A type of description research method)
- Observation of behavior in its natural setting
-Critical for observers to be as unobtrusive and inconspicuous as possible
-People are less likely to behave naturally when being watched
Pros:
▪ Validity (accuracy) of information collected unobtrusively in a natural setting
Cons:
▪ Often difficult to set up and control
▪ Observer bias
21
Q
What are case studies?
A
(Observational research studies focusing on one or a few people)
-Typically common with studying rare characteristics in people
Pro:
▪ Focuses attention on a special group of people
Con:
▪ Difficult to generalize any findings to the population as a whole
22
Q
What is a survey?
A
(List of questions to be answered by research participants, given as paper-and-pencil questionnaires, administered electronically, or conducted verbally, allowing for researchers to collect data from large number of people)
Pro:
▪ Collects information from larger samples of people
Con:
▪ Larger sample sizes do not provide the same depth of information in comparison to a case study
23
Q
What is archival research?
A
(Relies on looking at past records or data sets to look for interesting patterns or relationships)
Pro:
▪ Less of a money and time investment
Con:
▪ Questions have to be tailored to be answered within the structure of the existing data sets
▪ No guarantee of consistency between records
24
Q
What is longitudinal research?
A
data-gathering is administered repeatedly over an extended period of time
25
What is cross-sectional research?
Researcher compares multiple segments of population at the same time
-Comparing different groups of people by age, gender, or culture
26
Correlational and experimental both use ___________ testing, whereas descriptive doesn’t
Hypothesis
27
What is a positive correlation?
When two variables change in the same direction, both becoming larger or smaller
ex: the relationship between the amount of time a student spends studying and their exam scores. In a positive correlation, as one variable increases, the other variable also increases
28
What is negative correlation?
When two variables change in the opposite direction while one becomes larger the other becomes smaller
ex: as the amount of exercise increases, body weight tends to decrease.
29
How do you interpret a correlation coefficient?
where the number can vary between –1 to +1 showing the strength of the direction of the relationship between variables +1 and –1 both being strong and the closer to 0 is less strong
30
What is a dependent variable?
The variable that the researcher uses to see how much effect the independent variable had.
30
What is an independent variable?
a variable that is influenced by the experimenter, this shows what the difference between the experimental and control group is.
31
What is the control variable?
Any variable that is held constant in a research study
32
What is a cofounding control variable?
An unmeasurable variable that influences both the supposed cause and effect
ex: Imagine you're studying whether eating breakfast (independent variable) influences student performance on a test (dependent variable). A cofounding variable could be sleep quality. Students who sleep better might both eat breakfast regularly and perform well on tests. To control for this, you include sleep quality as a control variable
33
What is random sampling?
a subset of a larger population that everyone in the population has the same probability of being selected.
34
What is random assignment?
where all participants have the same chance of being assigned to either group.
35
What are the three stages of the memory process?
1. Encoding
2. Storage
3. Retrieval
36
Encoding
the process of converting sensory input into a form that the brain can understand and use
ex:when you hear a new phone number, and your brain converts the auditory information (the sound of the numbers) into a memory trace that you can later recall when needed.
37
Storage
Information is stored in the brain (like a computer hard drive)
38
Retrieval
Information is brought out when needed (like a computer screen when needed)
39
Atkinson-Shiffrin Model of Memory
Memories are composed of three primary stages and three different processes
The stages are sensory, short-term memory, and long-term memory
(While the processes are encoding, storage, and retrieval)
40
Compare and contrast the stages of the memory process and the Atkinson-Shiffrin model of memory
They are similar because they both have input as the first step in some form. They differ
when it comes to types of storage and details on how memories are retrieved
41
What are the two types of long-term memory?
Explicit memory (declarative)
Implicit memory (non-declarative)
42
Explicit memory
(type of long-term memory)
It involves the ability to recall facts, experiences, and events consciously (declarative memory)
ex: when you are studying for your chemistry exam, the material you are learning will be part of your explicit memory.
Explicit memories are broken into episodic(experienced events) and semantic(knowledge and concepts)
43
Implicit memory
(type of long-term memory)
The retention of information and experiences without conscious awareness or intentional effort
ex:Imagine you learned to ride a bicycle when you were a child. Years later, as an adult, you decide to hop on a bike after not riding one for a long time. Even if you can't consciously recall every detail of how to ride a bike, your body seems to remember, and you can pedal and maintain balance relatively effortlessly.
Implicit memories are broken into procedural(skills and actions) and emotional
conditioning.
44
Episodic memory
Experienced events (first date)
45
Semantic memory
knowledge and concepts (state capitol)
46
Procedural memory
skills and actions (driving a car, ride a bike)
47
Emotional conditioning
earning to associate an emotion with a stimulus (scared of
thunder)
48
Amygdala
Regulates emotions, such as fear and aggression.
It plays a part in how memories are stored because storage is influenced by stress hormones.
ex: During pavlovian conditioning, a neural tone was paired with a foot shock to the rats. This produced a fear memory in the rats
49
Hippocampus
important for memory, vital in the formation, consolidation, and retrieval of memories
50
Cerebellum
It involves procedural memory, motor learning, and classical conditioning
51
Prefrontal cortex
Researchers have used brain scans to see how people learn and process information
52
What are the two types of amnesia?
1. Retrograde amnesia
2. Anterograde amnesia
53
Retrograde amnesia
when a person cannot remember anything before the accident
54
Anterograde amnesia
when a person cannot remember things after the accident
55
Proactive interference
when the old information interferes with the new information (saying its 2022 when its 2023)
56
Retroactive interference
when the new information prohibits remembering the old information (just learned chapter 13 so you have a hard time remembering chapter 3)
57
What is the difference between the types of amnesia and interference?
amnesia happens after an accident, which is problematic, while interference is just everyday forgetting and you should not worry about it.
58
What are the 7 types of memory errors?
1. Transience
2. Absentmindedness
3. Blocking
4. Misattribution
5. Suggestibility
6. Bias
7. Persistence
59
Transience
(type of memory error)

- Forgetting
ex: getting old and forgetting what happened when you were a kid
60
Absentmindedness
(type of memory error)
When attention is focused elsewhere causing lapses in memory
- Forgetting
ex: forgetting where your phone is whilst talking to someone
61
Blocking
(type of memory error)
When you can’t access stored information (Tip of the tongue)
- Forgetting
ex: when information is “on the tip of your tongue”
62
Misattribution
(type of memory error)
Confusing the source of information on your own
- Distortion
Misattribution is a memory error that occurs when people attribute a memory to the wrong source, context, or person
ex: Imagine you hear a rumor about a celebrity, and later, you mistakenly recall that information as if it were something you personally witnessed or read in a reliable news source. The misattribution occurs when you attribute the information to a different and more credible source than the original rumor.
ex: recalling a dream as a waking memory
63
Suggestibility
(type of memory error)
When external sources lead to the creation of false memories
- Distortion
ex: results from leading questions
64
Bias
(type of memory error)
How one's current feelings and view of the world can distort memory of a past event
- Distortion
ex: witnessing something in person but when describing the event later you include details you didn’t see at the time but that were said on a new story about the event
65
Persistence
(type of memory error)
Involuntary recall of unwanted memories, usually unpleasant
- Intrusion
ex: PTSD patient suddenly recalling a traumatic event
66
Rehearsal
(memory-enhancing strategy)
Repeating information to be remembered
ex: learning multiplication tables
67
Chunking
(memory-enhancing strategy)
Organizing information into smaller bits/chunks
ex: memorizing a phone number in a 3-3-4 number sequence
68
Elaborative rehearsal
(memory-enhancing strategy)
the process of actively relating new information to existing knowledge or memories
ex:such as associating a new person's name with characteristics of someone you already know well
Thinking about the meaning of new information and its relation to already known knowledge
69
Mnemonic devices
(memory-enhancing strategy)
A memory aid that organizes information for encoding
ex: Never Eat Soggy Waffles (north-east-south-west)
70
Shadow Task
A task in which the individual is asked to repeat an auditory message as it is
presented
71
cocktail party phenomenon
refers to the ability to focus one's attention a particular stimulus while filtering out a range of other stimuli (auditory)
72
Broadbent's filter model
(theory of selective attention)
suggests that, during selective attention, the mind initially filters incoming information based on its physical attributes (like pitch or location) before engaging in deeper cognitive processing, allowing the brain to focus on specific stimuli while temporarily ignoring others.
73
Treisman's attenuation Model
(theory of selective attention)
Suggested that selection starts at the physical or perceptual level, but that the unattended information is not blocked completely, it is just weakened or attenuated. As a result, highly meaningful or pertinent information in the unattended ear will get through the filter for further processing at the level of meaning
74
Schemata
"Mental frameworks" or structures that organize information and help individuals understand and interpret the world around them
the mental scalding between categories
74
Categorization
the way we sort objects into groups, known as cognitive categories, that help us organize knowledge ("general groupings")
ex: we can quickly recognize that a cat and a dog both belong to the group "animals." Both have four legs and a tail prototype is defined as a mental representation of an object or concept
75
Prototype psychology
a mental representation of the idealized form of an object or concept
They are used to quickly identify and recognize instances within a group.
ex: when thinking of a "fruit," the prototype might be an apple or banana, influencing how quickly one recognizes less prototypical fruits like a pomegranate as part of the category
76
Concepts
mental representations of categories or ideas
ex: the concept is "happiness." The concept of happiness represents a mental understanding of a positive emotional and psychological state.
77
Trial and error
(problem-solving strategy)
continue trying different solutions until problem is solved
ex: restarting phone, turning off wifi, turning off Bluetooth in order to determine why your phone is malfunctioning
78

Electroencephalography (EEG)
records the electrical activity of the brain via electrodes on the scalp.
Mainly used in sleep research.
132
Functional magnetic resonance imaging (fMRI)
Instead of looking at an image, they look at brain activities and areas that are more active.
It measures oxygen so regions that have more oxygen are considered more active areas.
133
Computerized tomography scan (CT)
we use x-rays for this image technique measuring particular section of a person’s body or brain
134
Magnetic resonance imaging (MRI)
a person is placed inside a machine that generates a strong magnetic field. Magnetic residence images; using magnets, detailed structure in depth. It can take hours

136
NREM sleep stage 1
Light sleep; low respiration, heart rate, body temp, and muscle tension
-When woken up you report you weren't asleep
- Alpha waves: then moves to theta waves which is lower frequency and high amplitude
-lasts several mins
137
NREM sleep stage 2
deep relaxation
-theta waves
-sleep spindles (rapid bursts of high-frequency brainwave that is
good for memory and learning)
-K-complexes (high amplitude of brain wave to respond to something in environment)
138
NREM sleep stage 4
Deep sleep
- delta waves: low frequency and high
- often say didn't get good sleep if woken up during this time, this is no dreaming and high muscle tone
138
NREM sleep stage 3
Slow wave sleep; transitional stage
- delta waves: low frequency and high
139
What does NREM and REM stand for?
non-rapid eye movement; rapid eye movement
140
REM sleep
Paradoxical sleep because low muscle tension and high brain waves (beta) (paradoxical bc muscles are essentially paralyzed)
-This involves dream and is rapid eye movement
-Beta waves: the same waves we have when we are awake
141
Psychological dependence
has emotional bond to and does it to relieve mental states (the feeling of needing the drug)
142
Physiological dependence
changes in normal body activities
ex: development of withdrawal symptoms such as tremors and nausea in individuals who abruptly cease chronic alcohol consumption, reflecting the body's adaptation to the presence of the substance.
143
Depressant + drugs in that category
substances that enhance the activity of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain
suppresses CNS activity using GABA and chloride channels (cl-), which makes the cell more negative

Describe Pavlov’s study
Pavlov's experiment consisted of him ringing a bell shortly after presenting food to the dogs. At first the dogs did not elicit a response to the bells. However, eventually, the dogs began to salivate at the sound of the bell alone.
148
Describe classical conditioning
a learning process where an originally neutral stimulus becomes associated with a meaningful stimulus, leading to a conditioned response. (Pavlovian Conditioning)
-Classical conditioning is where one is behaviorally trained
- a category of associational leaning
- With US/CS/NS/UR/CR
Conditioned = learned, Response = behavior
149
Describe US/CS/NS/UR/CR for classical conditioning
(US)-Unconditioned Stimulus
- causes a response without any prior learning on the part of the subject
(UR)-Unconditioned Response
- an unlearned behavior or reflex
ex:
- US= dust in the air, UR= sneezing
- US= hitting your knee, UR= knee jerk
(NS)-Neutral Stimulus -> becomes (CS)-conditioned stimulus
- Does not elicit a response
- Does not “mean” anything
150
Fill in blanks with US/CS/NS/UR/CR- classical conditioning
You see an unfamiliar car (__) and your grandmother (__) gets out of it-- you are happy to see her (__). The next day, the same car drives up (__) and you are happy because you know she is in it (__)
NS, US, UR, CS, CR
ex: You see an unfamiliar car (NS) and your grandmother (US) gets out of it-- you are happy to see her (UR). The next day, the same car drives up (CS) and you are happy because you know she is in it (CR)
-The unfamiliar car that was once a neutral stimulus that did not mean anything, is now a conditioned stimulus because it means your grandmother is here
151
Higher-order conditioning
When a neutral stimulus(NS) becomes linked to a Conditioned
Stimulus(CS)
All that is required for this process is for the neutral stimulus to become
associated with a prior conditioned stimulus
ex: Unconditioned Stimulus (sugar/ice cream)
- Uncle gives you money, you use money to buy ice cream
- Money gets you ice cream
- Next time, you’re happy to see you uncle
(uncle=money=ice cream)
152
Acquisition
the initial stage of learning in classical conditioning
where the relationship between the US and the UR is established, leading to the development of a conditioned response(CR)
(concept of classical conditioning)
153
Spontaneous Recovery
when behavior is thought to be extinct but returns after some time
-After a period of extinction, if the conditioned stimulus (CS) is presented again, a weak or partial reappearance of the conditioned response (CR) may be observed
(concept of classical conditioning)
153
Extinction
here the relationship between the US(unconditioned stimulus) and the UR(unconditioned response) stops/ grows weaker
the learned association weakens or is extinguished over time
(concept of classical conditioning)
154
Operant Conditioning
A learning method that uses rewards or punishment to modify and change behavior. Behavior rewarded is likely to be repeated, behavior punished rarely occurs
(conscious learning)
155
What psychologists were relevant with Operant Conditioning?
B.F Skinner behind the study of Operant Conditioning
156
B.F. Skinners study
involved shaping behavior through reinforcement or punishment.
-rats in skinner box, reinforced or punished with stimuli like food rewards, electric shocks.
157
Describe the 4 types of Operant Conditioning
1. positive reinforcement- adding something to increase desired behavior (giving a child ice
cream because of a good grade)
2. negative reinforcement-taking something away to increase desired behavior (taking a toy
away from a child because of bad behavior)
3. positive punishment- adding something to decrease undesired behavior (giving a rat a shock
for behavior)
4. negative punishment- taking something away to decrease unwanted behavior (taking food
away from a rat to decrease behavior)
158
What are the 4 stages of reinforcement?
1. Fixed Ratio- rewards schedule when a reward is delivered after a specific number of
responses. (Ex. Getting paid every time you make 5 Tesla's)
2. Variable Ratio- The number of responses needed for a reward varies. (Ex. Slot Machines)
3. Fixed interval- When the reward only occurs after a certain amount of time. (Ex. A
monthly review at work)
4. Variable interval- provides reinforcement after random time intervals. (Ex. Someone
waiting for the Elevator)
159
Non-associational learning
behavior is implicit (ex: getting used to airplane sounds)
-occur without conscious awareness or intentional linking of stimulus
160
Latent learning
acquiring information without an obvious need to use it, and the knowledge becomes visible or demonstrated when there's a motivation or purpose for doing so, even if there was no immediate reward during the initial learning process.
earning that is not immediately apparent, not intentional
ex: a person learning the layout of a city while casually exploring without a specific goal, and later displaying that knowledge when needed, exemplifies latent learning
161
Observational learning
learning through watching others’ behaviors
162
Erikson’s psychosocial stages of development
1. Autonomy vs shame (1-3) - toddlers begin to explore their world, they learn they can
control their actions and act on the environment to get results. They begin to show clear
preferences for certain elements of the environment, such as food, toys, and clothing.
2. Initiative vs guilt (3-6) - preschool stage they can initiate activities and asserting control
over their world through social interactions and play
3. Industry vs inferiority (7-11) - begin to compare themselves to their peers to see how
they measure up
4. Identity vs role confusion (12-18) main task is developing a sense of self
5. Intimacy vs isolation (19-29) - after developing a sense of self in adolescence, we are
ready to share with others
6. Generativity vs stagnation (30-64) - contribute to society and be part of a family
7. Integrity vs despair (65+) - Assess and make sense of life and meaning of contributions
162
Piaget’s stages of cognitive development
[0-2 Years] Sensorimotor ~World experienced through senses and actions

[2-6 Years] Preoperational ~ Use words and images to represent things, but lack logical
reasoning
* Pretend play
* Egocentrism - unable to take the perspective of others
* Language development
[7-11 Years] Concrete Operational ~ Understand concrete events and analogies logically;
perform arithmetic operations

Define Kohlberg’s theories of moral development
3 stages of moral dilemmas
Level 1: pre-conventional morality
- (Stage 1) Obedience and punishment: behavior driven by avoiding punishment
- (Stage 2) Individual interest: behavior driven by self-interest and rewards
Level 2: conventional morality
- (Stage 3) Interpersonal: behavior driven by social approval
- (Stage 4) Authority: behavior driven by obeying authority and conforming to social
Level 3: post-conventional morality
- (Stage 5) Social contract: behavior driven by balance of social order and individual rights
- (Stage 6) Universal ethics: behavior driven by internal moral principles
(More women than men move past stage 4 of morality)
164
Heinz dilemma
example used to help us understand Kohlberg's stages of moral development
Woman with cancer needs radium medication to survive
◦ Cannot make enough money to get the dosage (even a smaller one) because the druggist
sells it at a higher price
◦ Husband went to the druggist to get a cheaper price, but he said no because since he
created it he wanted to make money off it
◦ Husband eventually got desperate and broke into the druggists' house and stole the drug

What are the 4 different types of attachment styles?
1. Secure attachment
2. Avoidant attachment
3. Resistant attachment
4. Disorganized attachment
167
Secure attachment
- Toddler prefers his parents over a stranger
- It is used as a secure base to explore the environment and is sought out in times of stress
- They are distressed when the caregivers leave the room in strange situation experiment but
when caregivers return, the child was happy to see them.
- These kids have caregivers that are sensitive and responsive to their need
- Healthiest attachment style
168
Avoidant attachment (insercure or anxious avoidant)
- The child is unresponsive to the parent, they don’t use the parent as a secure base and
don’t care if the parent leaves
- Toddlers react to parent the same way they react to strangers
- When parent does not return the child is slow to show a positive reaction
- Caregivers was insensitive and inattentive to their needs
169
Resistant attachment (ambivalent or anxious-ambivalent)
- Child shows clingy behavior then they regect the attachment figures attempt to interact
with them
* These children do not explore the toys in the room as they are too fearful
* During separation they become extremely disturbed and angry with the parents. When the
parent returns the child is difficult to comfort
* Caregivers give inconsistent level of response to their child
170
Disorganized attachment
- Behaves oddly in strange situation.
* They freeze, run around the room in an erratic manner or try to run away when the
caregivers return.
* This attachment is seen most often in kids who have been abused
* Shows that abuse disrupts a child’s ability to regulate their emotions
171
Authoritative parenting style
- Gives reasonable demands and consistent limits
* Expresses warmth and affection
* Listens to the child’s view points
* Sets rules but explains the reason behind them
* Flexible and willing to make exceptions to the rules
* The most encouraged for parenting styles for it being effective. Child tends to have high
self-esteem and social skills
* Most appropriate in basically all cultures
* The “strict but not strict” parenting style
Ex: Temporarily relaxing bedtime rules to allow for a nighttime swim during a family
vacation
172
Authoritarian style
- Place high value on conformity and obedience
* Strict, tightly monitor their child and express little to no warmth
* This style can create anxious, withdrawn, and unhealthy kids
* As beneficial as any other style in some ethic groups (First generation Chinese American
students raised by authoritarian parents did just as well in school as peers raised by
authoritative parents)
* Usually seen in eastern societies such as Asia.
ex: Strict bedtime and must obey or something may happen to the child
173
Permissive style
- Make few demands and rarely punish child
* Tend to be very nurturing and loving (may play role of friend rather than parents.
* Children raised by permissive parents tend to lack self-discipline and typically have bad
grades
* May contribute to risky behaviors such as alcohol abuse, risky sexual behavior among
females, increased display of disruptive behaviors by male children.
* Children raised by these parents have higher self-esteem, better social skills, and report
lower levels of depression
174
Uninvolved style
- Uninvolved sometimes referred to as neglectful
* Don’t respond to the child's needs and make relatively few demands
* It could be because of severe depression or substance abuse, or other factors such as the
parents' extreme focus on work.
* Parents provide for the child’s basic needs, but little anywhere else.
* Children raised with this parenting style are usually emotionally withdrawn, fearful,
anxious, perform poorly in school, and are at an increased risk of substance abuse
175
Describe fluid and crystallized intelligence
Fluid intelligence: Information processing abilities, such as logical reasoning, remembering lists,
spatial ability, and reaction time

understanding texts.
* Tends to increase as we get older
176

simple tasks are performed best when arousal levels are relatively high, while complex tasks are best performed when arousal is lower
181
What are Maslow’s hierarchy of needs
1st level: Physiological needs

3rd level: Belonging and love
(Friendship, love, family, and other factors that increase affiliation and intimacy; what every individual needs to feel belonging in their community)
4th level: Esteem needs
(Self-esteem, personal achievements, and other factors which create respect for others and for yourself; what every individual needs to feel good in their accomplishments
and character)

James-Lange Theory of emotion
The stimulus is presented, followed by a reaction or state of arousal, which then produces an emotional response.

183
Cannon-Bard theory of emotion
The stimulus is presented, followed by a bodily response and emotional response SIMULTANEOUSLY but independently of one another.
“Cannon-Bard - Cannons go off immediately.”
184
Schachter-Singer two-factor theory of emotion
suggests that emotions depend on two factors: physiological arousal and cognitive interpretation
ex: For instance, imagine you're in a dark alley, and your heart starts racing. According to the theory, your emotion (fear or excitement) depends on how you cognitively interpret the situation. If you think it's because you're excited about a surprise party, you'll feel excited; if you think it's because of danger, you'll feel fear. The theory highlights the role of interpretation in emotional experiences
