Q

Summary (history) of intelligence research

A

Early intelligence research was mainly motivated by practical needs, not theory-driven

It developed key elements of intelligence testing, in terms of:
What should be measured (vision -> multiple tasks)
Who could be tested (children -> adults)
Practicalities of testing (timed, group tests)
Comparisons across individuals (standardised IQ scores)

Q

Intelligence to the expert

A

In 1921 Journal of Educational Psychology asked 14 prominent psychologists to describe what comprises intelligence
Sternberg and Detterman (1986) replication with 24 experts

Jensen (1998): 38 experts, 38 definitions!

But Sternberg (2000) found some common themes:
adaptation to the environment
basic mental processes
higher order thinking (reasoning, problem solving, decision making)

Q

Summary (non-expert theories)

A

We have a strong intuitive sense
of what ‘intelligence’ is…

But:

The definition of ‘intelligence’ is different for different cultures, age groups, and subject areas

Lots of different traits, skills, abilities and achievements are associated with intelligence

Q

What are the current theories of intelligence?

A

General intelligence – Spearman’s g

Multifactor and hierarchical theories
Thurstone – primary mental abilities
Cattell – crystallised (gc) and fluid (gf)
Cattell-Horn-Carroll theory

Other intelligences
Multiple intelligences; emotional intelligence

19
Q

General intelligence (g)

A

1904: Charles Spearman tested children
‘intelligence’ tests
memory, light, weight, sound discrimination
‘intellectual’ tests
vocabulary, maths, spatial abilities

Positive Manifold: Positive correlation between scores on different tests, e.g. Children who did well on one test tended to do well on others

Spearman championed the use of factor analysis, to group correlated tests together, adapted from Jensen (1998)

20
Q

Spearman’s theory of intelligence (1904):

A

‘Specific abilities’ or ‘s’ (e.g. vocabulary intelligence, mathematical intelligence, etc.)

‘General intelligence’ or ‘g’ (i.e. underlying “mental energy”)

21
Q

Thurstone: multiple factors

A

Thurstone (1938) argued that ‘g’ was the result of, rather than the underlying mechanism behind, 7 primary mental abilities:

Associative memory – rote learning
Number – carry out mathematical operations
Perceptual speed – perceive details of visual stimuli
Reasoning – inductive and deductive reasoning
Space – transform spatial figures mentally
Verbal comprehension – reading, comprehension, verbal analogies
Word fluency – generate and use words and letters

22
Q

Cattell: Crystallised & fluid intelligence

A

Cattell (~1966): ‘g’ comprises two related but distinct components
Crystallised intelligence (Gc)
acquired knowledge and skills, vocabulary, comprehension, factual knowledge, etc.

Fluid intelligence (Gf)
reasoning ability, problem solving, patterns, analogies, understanding new information

Dynamic (changing) relationship between the two components

23
Q

Cattell-Horn-Carroll (CHC) theory

A

Influential theory of intelligence, especially for the development of IQ tests

A combination of:
Cattell’s concept of crystallised and fluid intelligence
Horn’s additional ‘g’ abilities
Carroll’s three-stratum hierarchical model

Combined to develop the Cattell-Horn-Carroll (CHC) theory of cognitive abilities (1999)
Influential in the development of IQ tests
Dynamic theory

24
Q

Horn: additional ‘g’ abilities

A

Horn worked with Cattell

Concluded that there were 9 broad ‘g’ abilities (no single ‘g’)

Cattell-Horn Gf-Gc (~1985)

25
Carroll: Three-stratum model (1993)
Hierarchical model based on factor analysis of 461 datasets obtained between 1927 and 1987 3-level hierarchy: -Stratum I: 69 different cognitive abilities -Stratum II: 8 broad factors arising from these abilities Stratum III: general intelligence (g)
26
What is Stratum II
fluid intelligence (Gf), crystallised intelligence (Gc), general memory and learning (Gy), visual perception (Gv), auditory perception (Gu), retrieval ability (Gr), cognitive speediness (Gs), processing speed (Gt)
27
CHC theory summary
Three-stratum theory 16 broad-stratum intelligences (sometimes 10) Fluid (Gf) & crystallised (Gc) intelligence General knowledge (Gkn), quantitative knowledge (Gq), reading/writing (Grw) Visual-spatial (Gv), auditory (Ga), olfactory (Go), tactile (Gh), psychomotor (Gp) & kinaesthetic (Gk) abilities Cognitive processing speed (Gs), decision/reaction time (Gt), psychomotor speed (Gps) Short-term memory (Gsm) & long-term storage & retrieval (Glr) Lots of narrow-stratum intelligences
28
Gardner: Multiple intelligences
Howard Gardner: Educational psychologist, interested in educational theory and practice Traditional intelligence testing does not translate easily into the classroom Western education systems: focus on logical-mathematical and linguistic intelligences Less focus on interpersonal intelligence
29
What 7 intelligences did Gardner identify?
Gardner (1983) Identified 7 intelligences ‘Conventional’ intelligences: linguistic logical-mathematical spatial Other types of intelligence: musical bodily kinaesthetic (using the body) interpersonal (relating to others) intrapersonal (understanding oneself)
30
Extra two intelligences identified by Gardner?
... plus an extra two (Gardner, 1998; Gardner et al., 1996) Naturalist (ability to interact with nature, maybe good at biology or meteorology) Existentialist (ability to understand one’s surroundings and place in the grand scheme of things)
31
Emotional Intelligence?
Ability to understand our own emotions and the emotions of others Ability to use emotional information to guide thinking and behaviour Theory Four-branch model of emotional intelligence - Salovey & Mayer (1990) Theory of emotional intelligence - Goleman (1995) Emotional-social intelligence model - Bar-On (1997, 2005)
32
Four-branch model of emotional intelligence (Salovey & Mayer, 1990)
Low sophistication: Perceiving - recognising emotions Facilitating – using emotions to make judgements & prioritise Understanding –emotions and how they are linked Managing – detached evaluation, emotional regulation High sophistication
33
Goleman's theory of emotional intelligence
Emotional intelligence is about learning to control our basic emotional responses e.g. fight or flight ‘Mixed’ model of emotional intelligence emotional intelligence (emotional awareness) personality and behaviour traits (conscientiousness, adaptability, trustworthiness)
34
Goleman (2001); Goleman et al. (2002): Four emotional competencies
Self-awareness (identify own emotional states) - service orientation, empathy Self-management (manage own emotions) Social awareness (assess and influence others’ emotions) Social skills / management (sustain good interpersonal relationships) - leadership, teamwork abilities Based on 25 abilities
35
Bar-On: Emotional-social intelligence model
Bar-On (1997, 2005): Emotionally and socially intelligent behaviour is adaptive Emotional expression important for adaptation and survival
36
Emotional-social intelligence model
Interrelated emotional and social competencies: understand and express themselves effectively understand and relate to others cope with environmental demands and pressures Mixed model (emotional intelligence & behavioural traits like optimism) Five major domains; 15 aspects
37
5 Main domains of emotional-social intelligence model
Intrapersonal skills, interpersonal skills, adaptability scales, stress-management scales, general mood
38
Intrapersonal skills
Recognise own emotions, emotional self-awareness, assertiveness, self-regard, self-actualisation, independence
39
Interpersonal skills
understand others' emotions, Interpersonal relationships, social responsibility, empathy
40
Adaptability scales
manage emotions, Problem solving, reality testing and flexibility
41
Stress-management scales
manage change, Stress tolerance, impulse control
42
General mood
generate positive affect, happiness and optimism
43
Comparing ability and mixed models
Salovey & Mayer: emotional intelligence only ‘emotional intelligence’ clearly defined can look at relationship between emotional intelligence and other variables (mental health, school) Goleman and Bar-On: mixed models abilities that emotionally intelligent people have, including abilities and behaviours useful in the workplace for identifying EI role in success
44
Critique of EI theory and research
No benchmark to establish meaningfulness of emotional intelligence Mixed models – mixing intelligence and personality factors is ‘unscientific’ (Eysenck, 2000)
