Q

Raven’s Progressive Matrices (RPM) 1938

A

*WAIS was criticised for being reliant on skills developed in Western culture

-MZ, r= .84-.88
DZ, r= .54-.60

25
Q

Intelligence and Genes

-amount of grey matter

30
Q

Intelligence and the environment [accounts for 30-50% of variance in intelligence]

Bouchard et al (1981,1990)

A

30% of IQ variance in children can be explained by shared environment.

31
Q

Intelligence and the environment [accounts for 30-50% of variance in intelligence]

Schiff et al (1982,1986)

A
  • socioeconomic status
  • adoption into middle-upper class
  • WISC competed at 10
  • IQ correlates with families SES r=.4 (Lubinski,2004)
32
Q

Intelligence and early interventions

Head start

A
  • compensate for limited learning environments
  • half a day at ate 4

=not a great outcome

*was not intense enough

33
Q

Intelligence and early interventions

Abecedarian Programme

A

-more intensive 6months-5 years

=increase in intelligence in this group compare to controls

34
Q

Confounding variables

A
  • persistence
  • motivation
  • interest
  • self efficacy
  • test anxiety

25-30% variance in academic an job performance explained by IQ.

35
Q

Definition is too narrow:

A
  • manual practical problems
  • creative problems
  • physical problems
  • interpersonal problems
36
Q

Multiple Intelligences

A

Gardener (2003)

37
Q

Goleman (1995)

A

emotional intelligence accounts for more variance when predicting life success

38
Q

Mayer and Salovey (2004)- emotional intelligence test

A
  • perceiving emotions: ability too recognise emotions in oneself and others
  • using emotions: using emotion to communicate in cognitive processes
  • understanding emotions: understand info and meaning
  • managing emotions: open to feelings and modulate to promote growth
39
Q

Emotional intelligence and predictors

A

Emotional intelligence and higher life satisfaction and subjective wellbeing. r=.4-.5

Emotional intelligence a strong predictor of wellbeing than IQ (mediated by SES).
