Q

What is the cross-cultural applicability of intelligence?

A

If intelligence helps people adapt and manage tasks, it should be cross-culturally applicable; but what a society understands as intelligence is linked to their particular ecology and social structure.

Different culture means there are different circumstances that people need to adapt to.

SPEARMAN’S TWO-FACTOR THEORY

What is it?

A

It arose from correlation and factor analysis of different intellectual task (how different variables group together)

Found correlation between individuals scores on different ability tests.

An individuals performance on an intelligence test is determine by two factors (g) and (s)

Q

CATTELL & HORN

What is fluid intelligence (Gf)?

A

An inherent, non verbal capacity to learn and to solve problems. It is not reliant on the capacity of language.
It is used to adapt to new situations.

It is not as influenced by background as it is relatively free from cultural elements such as schooling, training, life experience.

CATTELL & HORN

What is crystallised intelligence (Gc)?

A

It is the accumulation of abilities learned through schooling or life experience.It is learned habitual response, heavily dependant on schooling or life experience.

It relates to thing actively taught to us e.g. vocabulary tests, tool identification tests for motor mechanics.

Q

What is the information processing approach?

A

Assumes performance is normally distributed across a variety of intelligence relevant capacities.

Assumes performance on one capacity is weakly to moderately related to performance on other capacities.

Therefore person 1 might be better at A and B but person 2 might be better at C and D

Q

BIOLOGICAL FACTORS

Is intelligence influence by other cognitive abilities?

A

There is a relationship between memory and intelligence, but working memory is different to long term memory, and you can have poor memory and above average intelligence.

34
Q

BIOLOGICAL FACTORS

Is intelligence influenced by abilities like reaction time?

A

Faster nerve response to visual stimuli correlates with non-verbal I.Q.

35
Q

BIOLOGICAL FACTORS

Do biological factors influence intelligence?

A

Intelligence is complex and multifaceted, it cannot be reduced to a single denominator. It may be due to how efficient our brains are

36
Q

How did IQ tests emerge?

A

Alfred Binet was the first person to establish tests. He tested resting and logic. The tests had reasonable predictive validity and spread throughout the US and Europe.

37
Q

What was Binet’s criteria for selecting an item?

A

Item has to relate to ‘common sense’
Item has to be a part of daily life
Item must separate ‘dull’ from ‘bright’ children
Item must be practical and easy to administer.

38
Q

What is a mental age?

A

average age at which children achieve an actual score.

an intellectually disabled child would not be able to answer questions typical for their chronological age.

39
Q

What are the modern tests of intelligence?

A

In 1916 Louis Terman revised Binet and called it the Stanford-Binet which is still in use today but not as much as other tests.
Revised items did not perform as well as expected, he then added adult items and introduced the use of Intelligence Quotient (the amount of intelligence)

40
Q

What is the Intelligence Quotient (IQ)?

A

Allows comparison of test scores among persons, Terman and Stern devised the concept of the IQ
IQ = (Mental Age/Chronological age) x100

41
Q

What were the problems with Stern’s IQ?

A

Calculating IQ works well for children as their abilities are still developing

Development slows in adolescence

Development stabilises in adulthood

Comparing mental age to chronological age makes little numerical sense for adults.

42
Q

DAVID WECHSLER (WAIS)

Why is he significant?

A

He developed a test specifically for adults.
He developed tests for children (WISC) based on the WAIS.
He attempted to remove the biases associated with earlier intelligence tests
His scales allowed psychologists to identify areas of strength and weakness within individuals and are the most commonly used IQ tests in western cultures today.

43
Q

DAVID WECHSLER (WAIS)

Where are his scales at now?

A

IQ is measure on a number of subtests which distinguish between Verbal and non verbal intelligence.

WAIS = Weschler Adult Intelligence Scale

Q

How do we interpret scores?

A

The mean

Standard deviation

Standardisation

Norms

54
Q

A

Adding all the scaled scores together from the 4 groups

An average IQ is between 85 and 115

55
Q

What defines intellectual disability?

A

Encompasses a wide range of cognitive abilities, defined in the DSM-V as:

1) significant deficits in intellectual functioning.
2) Concurrent deficits or impairments in adaptive functioning
3) Onset in the developmental period

May be due to different origins, genetic, biological or environmental.

56
Q

What are adaptive skills?

A

Conceptual:
communication
Functional academics
Self direction

Social:
Leisure
Social interaction

Practical:
Community use
Home living
Health & Safety
Self care

Other tests to show how Ps are performing

57
Q

What defines Giftedness?

A

Can reflect academic, musical, social or athletic ability. It is often associated with an IQ over 130.
Stereotypes associated with it include:
Physically weak
Mentally unstable
Reclusive/eccentric
Compensation - talent in one are is accompanied by a deficit in another.

58
Q

What are the characteristics of the gifted?

A

Above average height, strength, emotional maturity and other variable as children.
Health, emotional stability and satisfaction above average in adulthood.

59
Q

What are the 3 intersecting components of true giftedness?

A
  1. Exceptional intelligence in specific domain
  2. Exceptional creativity
  3. Exceptional motivational
60
Q

What is creativity?

A

The ability to produce valued outcomes in a novel way.

61
Q

What is Divergent thinking?

A

The ability to generate multiple possibilities in a given situation.

62
Q

What is convergent thinking?

A

Finding the best idea from the range of ideas generated through divergent thinking

63
Q

How does psychometrics relate to IQ?

A

Intelligence tests are unusual in science; measures were developed first and then the theories evolved to fit those measure. Where it is usually the other way around.

64
Q

What are the criticism of the IQ test?

A

Lack of theoretical basis (no underlying construct)

Cultural bias (scores depend on language and cultural experience)

Ecological validity

What will predict performance

65
Q

Do IQ scores predict real world outcomes?

A

People who score high on IQ tests are more likely than those who score low to end up in high status jobs.

They are good predictors of future school performance
And school performance is linked to attaining certain jobs.

Correlations between (g) and hob performance are often weak.

66
Q

ABUSE OF INTELLIGENCE TESTS

What were the worst abuses?

A

Was the eugenics movement were the ‘mental defectives; were isolate, sterilised or exterminate as they wanted to breed them out.

67
Q

ABUSE OF INTELLIGENCE TESTS

How was Binet’s work corrupted?

A

It was used as a diagnostic tool for feeble children; they wanted to segregate them so they would not contaminate.

They also used it to assess immigrants as they did not want ‘unintelligent immigrants’; they became convinced that ‘feeble mindedness’ was common in immigrants

68
Q

ABUSE OF INTELLIGENCE TESTS

What tests were used in the corruption of Binet’s tests?

A 
Bead stringing
Shape copying
Counting coins
Naming objects
Recalling digits
Word definitions
Filling in the missing word in a sentence

If you are not from a particular culture, these tests could be incredibly hard.

69
Q

CULTURE FAIR TESTS

What was the original purpose of tests?

A

To provide valid, objective, socially unbiased measurement of intellectual ability however tests can never reveal innate intelligence or culture free knowledge.

70
Q

CULTURE FAIR TESTS

What should culture fair tests include?

A

They should include items that would measure common skills and knowledge across cultures.

Thus intelligence tests thus need to be considered within a culture.

71
Q

What are the genetic explanations?

A

Genetics and environment is important but neither are the be all and end all

72
Q

How do you calculate heritability?

A

Formulas used to assess heritability were developed about 60 years ago.

73
Q

What are the important environmental factors?

A

Enriched home environment
Encouraging interest and exploration
Mother’s knowledge about child rearing

These are all positive predictors of children’s performance on IQ and language tests

74
Q

What are the risk factors for a lower IQ in the environment?

A 
Poor maternal education
Maternal mental illness
Minority status
Larger family size
Poverty
Poor nutrition
75
Q

Is there a socio-cultural disadvantage?

A 
Children in low SES areas may fail to develop full intellectual potential
I.Q difference between highest and lower social class is a difference of about 20-30 points
76
Q

What is a stereotype threat?

A

It is a belief about your group which leads to greater anxiety which leads to your self fulfilling prophecy

77
Q

What are the controversies?

A

Racial differences in IQ tests are due to deprived environments

78
Q

What is within group heritability?

A

The extent to which a trait varies within a specific group, due to the genetics influences

79
Q

What is between group heritability?

A

The extent to which differences in a trait between groups is genetically influenced

80
Q

What is there to conclude about intelligence?

A

IQ represents complex interaction between nature and nurture.

More recent theories of intelligence move away from the narrow confines of IQ scores

However the tests are still prevalent in western society

Twin and adoption studies indicate genetics are important in explaining individual differences

Group differences are typically more reflective of environment rather than genetics.
