Q

Is it nature or nurture?

A

It’s a mix of both and interactive. What needs to be done is to try to figure out how the interplay of genes and environments plays out for each ability. How is this ability learned or how is this innate knowledge/ability built into the brain.

Q

How are infants not tabula rasa (blank slate)?

A

People used to think that infants were blank slates, had to learn everything. Come into the world with lots of preferences and nascent (underdeveloped) abilities. These innate abilities guide and structure learning: allow children to learn.

Q

What are some methods for studying infant’s knowledge?

A

Infants looking time studies:

  1. Give infants a choice of looking at two or more things.
  2. measure what they look at longer
  3. Assumption is that infants will look at things they find novel or interesting more than old, boring things
  4. Test for ability to perceive differences as well as for preferences

Q

Main ideas from Johnson study about Newborns and Human faces

A

Infants were shown a blank shape, a proper face, or scrambled facial features.

Proper face and scrambled face have the same complexity.

Infants looked more intensely at the proper face.

Q

What are the discoveries from Mark Johnson’s Theory of Development Face Recognition Abilities

A

Two components, one innate, one that learns

Subcortical system has sketchy knowledge of what face should look like. Cortical system can learn about faces.

How they work together. Innate knowledge in subcortical system causes infants to focus on faces. Then, the cortical system is able to learn a lot about faces.

Q

General study of Johnson and imprinting with ducks

A

Chicks seem to have some innate knowledge of chicken faces. After chicks hatch, give them a choice of two moving objects. Varied properties of these objects to see what exactly what the chick prefers. For example, a red box vs. a stuffed chicken or just chicken parts (head and neck). Prefer bird head and neck in proper configuration. Actually prefer just chicken’s head and neck to the whole hen.

Q

What did Lesioning studies show?

A

Where the innate knowledge is stored in the brain. Lesion this area and preference for chicken head/neck is gone. A different area of brain does the learning (and stores the knowledge of mother’s face). Lesion subcortical area after chick has a chance to imprint, chick can still recognize its mother.

Q

So is it innate or is learned for chicks?

A

Its BOTH. some minimal, innate knowledge that focuses the attention of the infant (or chicken) and guides learning. Knowledge of shape of head/neck of hen. For human babies knowledge of oval shaped face with 2 eyes and a mouth. AND another system (cortex) that learns the specifics of important faces from exposure to those stimuli.

Q

What is the Infant as Intuitive Physicist?

A

Infants look longer at objects that seem to violate physical laws than those that do not. Surprise indicates that their expectations were violated. They must know what is physically plausible for this to occur.

Q

What is the preoperational stage?

A

Ages 2-7. The child begins to represent the world symbolically.

Start of this period is marked by developing the ability to think in verbal symbols or words. Lacks “adult reasoning” key deficit is called the principle of conservation. Thinking is egocentric.

Q

Criticism of Piaget

A
  1. He underestimated children’s abilities.
  2. Object permanence: before 8-9 months children supposedly lack object permanence so if something is out of sight, its out of mind. But some studies seem to show that kids have knowledge of objects even if they can’t see or touch them .
38
Q

Examples of the critiques of Piaget in kids.

A

Egocentrism: if asked to show mommy a picture, 2-3 year olds will turn the picture the correct way.

Conservation: When children play a game where the “number” determines the winner, they are not thrown off by changes in the spacing.

39
Q

More criticisms of Piaget: Are there really “stages”

A

The behaviors that emerge in a stage are consistent with each other. In the sensory motor stage, object permanence and stranger anxiety go together. Similarly, in the Preoperational stage, children fail to conserve numbers, mass, and volume. Second, stages tend to be discrete (relatively abrupt transitions) rather than continuous.

40
Q

Attachment

A

A deep emotional bond that an infant develops with its caretaker. Not as automatic as imprinting! No critical period!

40
Q

What did psychologists believe about infants and attachment?

A

Psychologists initially assumed infants would attach to anyone who feeds them and satisfies basic needs.

41
Q

Primary Drives Theory

A

Attachment results from associating the satisfaction of primary drives with the being who satisfies (hunger etc.)

42
Q

What was Harlow’s Study?

A

Tested primary drives theory on monkeys. 2 surrogate mothers, one wire and one cloth. Monkey was very attached to the cloth mother

43
Q

Schanberg and Field on the applications of Harlow’s work

A
  1. Contact important for premature babies
  2. Two groups of premature babies

Group 1: held for 45 minutes a day for 10 days. Group 1 was more alert, active, gained 47% more weight, left hospital six days earlier.

44
Q

Attachment

A

Attachment has important survival value. Has species-specific forms. Triggered by releaser stimuli.

45
Q

When does Stranger Anxiety begin?

A

Begins at around 6 months of age, younger kids are not afraid. Peaks at about 1 year and then declines. Occurs in all cultures. Greatest in unfamiliar settings.

46
Q

Secure Attachment

A

A parent-infant relationship in which the baby is secure when the parent is present, distressed by separation, and delighted by reunion

47
Q

Insecure Resistant Attachment

A

Baby clings to the parent, cries at separation, and reacts with anger to reunion

48
Q

Insecure Avoidant Attachment

A

Doesn’t care if mom leaves, doesn’t react when she returns.

49
Q

Ainsworth view: secure attachment

A

Securely attached kids use caretaker as a secure base (can explore world in safety with mom around)

50
Q

Ainsworth view: Resistant Insecure attachment

A

Resistant infants first seek and then avoid caretaker (hot and cold).

51
Q

Ainsworth’s View: Avoidant attachment

A

Avoidant infants are not attached at all

52
Q

When is parental responsiveness the highest?

A

In securely attached kids

53
Q

What are the general ideas from Bowlby’s theory?

A

Attachment experiences influence perceptions of others and later social relationships. May fail to thrive if attachment is absent. May fail to develop other social bonds. Tend to reproduce same pattern in other relationships.

54
Q

Harlow’s Monkey’s (Again): What happened when Monkey’s were deprived of their mothers for 1 year?

A

Longer periods of deprivation had major effects: monkeys huddle in the corner of the cage, rock back and forth.

55
Q

What happened when Harlow’s Monkey’s when they were reunited with the same age normally reared monkeys?

A

Didn’t play, they would withdraw and huddle, rock, and bite themselves

56
Q

What happened to the monkeys as adult abnormalities persisted?

A

The monkey’s became incompetent at parental and sexual interactions. Some cases, as mothers, they abused their children

57
Q

What happened with the monkeys when they put in a therapist monkey?

A

Deprived monkeys of mothers for 6 months. Then, put 3 month younger monkey in cage with them as a therapist. At first they avoided the younger monkey, but the “therapist” kept trying to play with them. Eventually, deprived monkey interacted with little friend and after 6 months recovered normal behaviors.

58
Q

What happened to deprived females who became mothers?

A

Acted abnormally with first child but many recovered when they had a second child. Treated second child normally. Perhaps, the first child acted like the “therapist” and helped the mothers recover.

59
Q

Delay of gratification

A

The ability to resist the temptation for an immediate reward and wait for a later reward.

60
Q

What is the delay of gratification linked to?

A

Academic success. Physical and psychological health, social skills, patience, will power, self control

61
Q

Adolescent Cognition

A

In formal operational stage.

Grasp theoretical math.

Understand abstractions: religious and political philosophy.

Decipher metaphors and analogies

62
Q

Imaginary audience

A

The strong focus on self leads adolescents to feel that everyone else is focused on them as well.

63
Q

Personal fable

A

Adolescents assume their thoughts and feelings are unique (no one has ever loved so deeply, etc.)

64
Q

Moral Reasoning: Kohlberg

A

Resolving Ethical Dilemmas

Presents subject with dilemma, asked to reason it out.

Found 3 stages of moral reasoning (with sub-stages get 6)

Big changes in adolescence.

65
Q

Kohlberg’s Theory: Pre-conventional level

A

Pre-conventional Level:

Stage 1 –> Punishment avoidance is “right”. example you could get caught and go to jail

Stage 2–> Whatever benefits the individual is “right” Example, it won’t do any good because his wife will die before he gets the drug (sort of egocentric?)

66
Q

Kohlberg’s Theory: Conventional Level

A

Stage 3: Behavior that pleases others is “right”
Example, he shouldn’t steal because others will think he is a thief

Stage 4: Authorities and rules determines what’s right
Example no one is allowed to steal, so why should he?

67
Q

Kohlberg’s theory: post-conventional level

A

Stage 5–> protecting both society and individual is “right”
example, laws are basis for a civilized society and they have to be respected.

Stage 6–> Universal principles determine “right” (only 5-10% of people). example of higher principle of saving a life outweighs the wrong of stealing

68
Q

What moral reasoning are the 7-10 year olds using?

A

Most 7-10 year olds are reasoning at the pre-conventional level

69
Q

What moral reasoning are 13-16 year olds using?

A

Conventional level

70
Q

How many subjects from 7-16 show post conventional type of reasoning?

A

Few subjects show the postconventional type of reasoning

71
Q

Research on Kohlberg

A

Stages 1-4 seem universal and invariant in order

Stage 5 found in urban cultures, uncommon in tribal and village societies

Possible gender and cultural biases

Connection between moral reasoning and moral behavior is often indirect.
