Longitudinal studies…

A

Thomas and Chess: Followed 100 children from birth to adolescence

Q

Brain regions that are associated with inhibited and uninhibited people…

A

Amygdala- centrally involved in the fear response

Frontal cortex- involved in regulating emotional response, in part, by influencing the functioning of the amygdala

Q

Ultimate Causes

A

why is a given biological mechanism a part of the organism, and why does it respond to the environment in a given way? (invokes principles of natural selection)

Q

4 Points of Evolution and the Human mind…

A
  1. The features of mind that evolved are all about passing on genes!
  2. Evolved mental mechanisms are adaptive to the way of life of hundreds of centuries ago
  3. Evolved psychological mechanisms are domain-specific
  4. The mind contains multiple information-processing devices

Q

Sex Differences

A

Sex differences inadvertently caused males and females to mentally develop differently than each other. (Sex differences are also socially constructed)

17
Q

Behavioral genetics

A

the study of genetic contributions to behavior by estimating the degree to which variation in psychological characteristics is due to genetic factors

18
Q

Selective Breeding Studies

A

animals with a desired trait for study are selected and mated

19
Q

Importance of twin studies…

A

Ability to see how environmental factors play into behavior sine the twins share the same genetics

20
Q

Importance of adoption studies…

A

heritability coefficient… allows us to study different parent-offspring, sibling-adoptive sibling behaviors and see the effect of environmental factors on behavior versus genetic traits

21
Q

Three kinds of nature-nurture interactions?

A
  1. The same environmental experiences may have different effects on individuals with different genetic traits
  2. Individuals with different genetic traits may evoke different responses from the environment
  3. Genetic factors influence the selection and creation of environments
22
Q

lateralization

A

hemispheric dominance

23
Q

hemispheric dominance

A

lateralization

24
Q

left-anterior brain activity…

A

when damaged, more likely to become depressed
responsible for activation during positive (negative) emotional states
worrying=strong activation of left anterior cortex

25
Q

right anterior brain activity…

A

when damaged can cause people to become manic

26
Q

neurotransmitters and temperament

A
  • Dopamine is associated with pleasure and appears to be central to the functioning of the reward system
  • Serotonin is important in regulating mood
  • Cortisol is the stress hormone associated with a stress response
27
Q

Amygdala

A

Part of the primitive limbic system, the brain’s emotional response center. Particularly important for aversive emotional learning

28
Q

Hemispheric Lateralization

A

Dominance of the right frontal hemisphere associated with activation of negative emotions and personality traits of shyness and inhibition; dominance of the left frontal hemisphere associated with activation of positive emotions and personality traits of boldness and disinhibition.

29
Q

Dopamine

A

Neurotransmitter associated with reward, reinforcement, pleasure. High dopamine levels are associated with positive emotions, high energy, disinhibition, and impulsivity. Low dopamine levels are associated with lethargy, anxiety, and constriction.

30
Q

Serotonin

A

Neurotransmitter involved in mood, irritability, and impulsivity. Low serotonin levels are associated with depression, but also with violence and impulsivity. SSRIs are used to treat depression, as well as phobias and OCD

31
Q

Cortisol

A

Stress-related hormone secreted by the adrenal cortex that facilitates reactions to threat. Adaptive in relation to short-term stress, responses to long-term chronic stress can be associated with depression and memory loss

32
Q

Testosterone

A

Hormone important in the development of secondary sex characteristics and associated with dominance, competitiveness, and aggression.

33
Q

Plasticity

A

the capacity of biological systems to change as a result of experience

34
Q

What parts of the brain are associated with self-judgement?

A

medial prefrontal cortex (some areas of the brain responsible for emotional responses as well)
