Reinforcement
Extinction

  1. Parents don’t teach kids language
  2. Kids generate new sentences
  3. Overgeneralizations not predictable
24

Both left cortex

Some right hemisphere activation

27

28
Q

Prototype theory?

A

We compare new instances to the category’s prototype

29
Q

How do we form categories and concepts?

A

We use prototypes and exemplars
Visual cortex for prototypes (image processing)
Prefrontal cortex and basal ganglia for exemplars (analysis and decision making)
Brain organization is innately determined

30
Q

Where do deficits happen?

A

Left temporal lobe - location specific

31
Q

What is intelligence?

A

The ability to direct one’s thinking, adapt to one’s circumstances, and learn from one’s experiences

32
Q

Why were IQ tests developed?

A 
To help children succeed in school
Logic
Memory
Copying
Distinguishing
Rhymes
Ethics
33
Q

What is the Wechsler test?

A

Solve problems, word meanings, general knowledge, explain actions

Predicts health, educational level, income

34
Q

What did Spearman find?

A

Children who scored well in one domain (music) scored well in others (algebra)
But not best
Two factor theory of intelligence

35
Q

What did Thurstone find?

A

No general ability like Spearman said

Only primary mental abilities like perception, verbal, numeric ability

36
Q

How is intelligence seen today?

A

Three factor hierarchy
General at top (g)
Primary mental abilities 8
Specific abilities (s)

37
Q

What are the middle level abilities?

A
  1. Memory and learning
  2. Visual perception
  3. Auditory perception
  4. Retrieval ability
  5. Cognitive speediness
  6. Processing speed
  7. Crystallized intelligence
  8. Fluid intelligence
38
Q

What did Sternberg say about intelligence?

A 
Distinguishes between analytic intelligence (identify, define, solve problems)
And practical intelligence (apply solutions in everyday settings)
Creative intelligence (generate unique solutions)
39
Q

Where does intelligence come from?

A

Not families
Twins IQ are similiar even when not raised together
Identical raised apart closer than fraternals raised together
Regular siblings not really
Correlation between siblings greater when closer in age

40
Q

What is the Flynn effect?

A

IQ 30 higher than 1900

41
Q

What enviro factors influence IQ?

A

Economics, education
12 points

Parents read and stimulate
Better health
Less stress
Fewer toxins
More words
School makes smarter but effects diminish
Experiments like Head Start and vouchers don’t increase smarts

42
Q

Where are males and females on spectrum?

A

Males more at either end
High intelligence less prone to mental illness
High iq kids as well adjusted as peers
Children rarely gifted in all areas

43

100 average
70% between 85 and 115
Less than 70 disability 70% male
Down syndrome, fetal alcohol

44
Q

What were Terman’s claims?

A

Intelligence genetic
Members of some race groups do better than others
Due to gene differences

First 2 true, 3rd not

Why?
Situational: gender identification, race identification
Enviro: SES

45
