Q

How does light affect the SCN, and how are the pineal gland and melatonin involved in our sleep-wake cycle?

A

If it is dark, the SCN directs the pineal gland to secrete melatonin, and when it is light out, the SCN directs the pineal gland to stop secreting melatonin.

Q

What are the theories explaining dreaming?

A

Freudian Dreams stem from unconscious thoughts

Activation synthesis Brain’s internally generated signals form dreams, dreams come from random neurons firing in the brain, where the content of our dreams come from

Information processing Memories of events form dreams

Preserving neural pathways Purpose of dreaming is to provide brain stimulation

What are the ways in which behavior geneticists can determine the relative contribution of genetic and environmental factors to traits and behavior?

37
What is reversibility?
Idea that a stimulus that has changed can return to its original state (Concrete operational)
38
What is transitivity?
Understanding how components in a series are related, (if A>B and B>C, then A>C) (concrete operational)
39
What is Vygotsky’s theory of cognitive development?
Cognitive development results from guidance
40
What is the zone of proximal development?
Level at which child can almost perform a task independently
41

44
What is Erik Erikson’s stage theory of social development?
Changes in interpersonal thought, feeling, and behavior
45
What are the major challenges in each stage of erik eriksons stage theory of social development? (first 4 stages for now)
Trust vs. mistrust If needs are dependably met, infants develop a sense of basic trust Autonomy vs. shame and doubt Toddlers learn to exercise their will and do things for themselves, or they doubt their abilities.Independence and self control Initiative vs. guilt Am I good or bad? Industry vs. inferiority Sense of competence or inadequacy
46
What were the results of Harlow’s studies of infant attachment?
It showed that soft contact is important to development
47
How did Mary Ainsworth study attachment?
What were her resulting attachment styles? Secure Child who is upset when parents leave and happy when parents return What is a secure base? Someone who the child trust and could go to Insecure-anxious/ambivalent Upset when parents left and did not calm when parents return Insecure-avoidant No reaction to parents leaving and coming back
48
What contributes to attachment styles (e.g., temperament)?
Temperament, stressful home life, parenting
49
What are the later correlates of infant attachment style (e.g., size of vocabulary)?
Size of vocabulary, interpersonal interactions, emotions
50
What was Langlois et al.’s (1995) study?
Infants rated for attractiveness, more attractive meant more affection and attention
51
What are Baumrind’s 2 dimensions of parenting?
Warmth(responsiveness) and control(demandingness)
52
What are the resulting 4 parenting styles?
Authoritative - high warmth, high control, not overly demanding or hostile, child centered Authoritarian low warmth, high control, very controlling and demanding, very restrictive and lots of rules Permissive high warmth, low control, very few rules and restrictions Uninvolved low warmth, low control, least effective and most detrimental
53
How do parenting styles predict later outcomes?
Authoritative - most optimal meaning higher grades and cooperation. Authoritarian - lower grades and lower self-esteem. Permissive - easily frustrated and low self-control. Uninvolved(neglectful) - low self-esteem, emotionally detached

59
What are Erik Erikson’s last 4 stages of social development? What is the challenge in each?
Identity vs. confusion (5th stage) Stable sense of who one is and what one’s values are or identity confusion Identity - who am I? Where do I belong? Intimacy vs. isolation established enduring, committed relationships, not always romantic Generativity vs. stagnation (midlife) Generativity - Generate things that contribute to the future of society. Stagnation - see life as meaningless Integrity vs. despair (late life) Ego integrity - feeling that one’s life has coherence and purpose. Despair - disappointment, regret

61
What is a critical period (3b (3.3.1))?
a period early in life when exposure to certain stimuli or experiences is needed for proper development
62
What are sensation and perception?
Sensation - Process by which sensory organs obtain information about the environment and transmit it to the brain. Perception - the organization of sensations into interpretations
63
What is transduction?
Translation of physical energy into electrical signals
64
What are bottom-up and top-down processing?
Starts with raw sensory data that gets communicated to the brain. Starts with observer’s expectations and knowledge
65
What are absolute thresholds?
Minimal amount of stimulation that can be detected half of the time
66
What are difference thresholds (the jnd)?
The smallest difference in intensity between 2 stimuli that a person can detect
67
What is Weber’s law (fraction)?
For 2 stimuli to be perceived as different in intensity, the second must differ from the first by a constant proportion.
68
What is sensory adaptation?
Decreasing response of sensory receptors to unchanging stimuli
69
What is signal detection theory?
Perception results from both sensory information and making a judgment that willl determine if we think that something is there or not
70
What is response bias?
Person’s readiness to report detecting a stimulus
71
What are hits, misses, false alarms, and correct rejections?
Hit is when there is a signal and you say there is. Miss is when there is a signal and you don’t say there is. False alarm is when there is no signal but you say there is. Correct rejection is when there is no signal and you say there is not.
72
What factors affect response bias
Expectations you expect something to happen and then give the wrong response Motivation How important is it to you that you detect something if it is possibly there
73
What is the Gestalt approach?
We perceive objects as whole rather than as a sum of the individual parts
74
What is figure-ground perception?
We inherently distinguish between object and background
75
What are grouping principles?
Proximity we tend to group together objects that are close to one another Similarity we tend to group together objects that are similar to one another Continuity brain organizes stimuli into continuous lines or patterns Closure We tend to perceive incomplete figures as complete
76
What are binocular and monocular cues for depth?
Binocular is when the visual input is integrated from 2 eyes. Monocular cues is when you can only use 1 eye
77
What is retinal (binocular) disparity?
Images produce different images on each retina
78
What is convergence?
Turning inward of eyes toward nearby object
79
What are relative size, relative clarity, and linear perspective?
Relative size - the farther away the object the smaller it looks. Relative clarity - the farther away something is the less clear it is. Linear perspective - with parallel lines they look like they are closer as they move away.
80
What is perceptual constancy?
Interpretation of changing sensations as perception that is relatively consistent
81
Color constancy
Consistent perception of color of objects although the amount of light changes
82
Lightness constancy
Consistent perception of shade of objects although the amount of light changes
83
Shape constancy
Perception that object’s shape remains constant despite changes shape of retinal image
84
