Intelligence Flashcards
Intelligence
Knowledge
Effectief denken en beredeneren
Adaptief omgaan met je omgeving
First attempt to measure intelligence
Galton
- erfelijkheid
- Sensory and perceptual skills (reaction speed)
- Size of the skull
Alfred Binet
- Assumed that mental abilities develop with age
- Chronological age VS mental age
- Developed the Binet Simon test
Binet Simon test
Taks of reasoning & problem solving
- verbal reasoning
- Quantitive reasoning
- Abstract reasoning
- Short term memory
Stanford-Binet Intelligence scales
- Fluid reasoning
- Knowledge
- Quantitative reasoning
- Visual spatial processing
- Working memory
Wechsler Scale
- Based on Carroll three stratum Theory
- WAIS for adults
- WISC for kids ouder dan 6 jaar
- WIPPSI voor kinderen 2 jaar en ouder
IQ
Ratio of mental age to chronological age multiplied by 100
- Now based on standardization, median is 100
Flynn effect
Gains in mean IQ for world regions
Factor analysis
Statistical method to identify clusters of variables that correlate highly with each other
Charles Spearman
-> factor analysis
Invented the G-Factor
G factor
- School grades in English and math correlate positively
- Tasks for the Stanford binet correlate postively
Thurston
Critises Spearman
- the correlations between tasks are positive but ar not that high
- There are 7 mental abilities
Catell & Horn
Combined model for intelligence
- General intelligence contains- > fluid intelligence and crystallized intelligence
Crystallized intelligence
Keeps developing Fluid intelligence (prefrontal cortex) has a peak around age 20 and that slightly decreases
Carroll´s three stratum theory
General intelligence is influenced by fluid and crystallized intelligence and the 7 abilities
IQ is an important predictor is
- academic success
- occupational success
- economic success
- health behaviors and outcomes
- resilience
What influences intelligence
Genes and environment
As the child grow older the genes play a more important role
Active effects
The genotype of a child influences the environment a child chooses
Passive effects
The overlap of the genotype of the parents and the child’s genotype influences the environment the child grows up in.
Evocative effects
Behavior of the child will influence the reaction of others to the child
