Intelligence Flashcards
what did sternberg and detterman find regarding common psychological definitions for intelligence
higher level abilities
valued by culture
executive processes
mental abilities necessary for adaption to any environmental context
how is intelligence measured
IQ test
what are deary & caryl’s 4 branches of IQ research
real life impact - achievements
cognitive - reaction times
biological - brain event potentials
structure of intelligence
what is the structure of intelligence branch
has a hierarchical structure
general intelligence split into learnt factors and biological potential
learnt includes spelling, writing and speech
biological splots into reading speed, piagetian reasoning, inductive reasoning
what is fluid intelligence (Gf)
focuses on process independent of content or prior knowledge
declines in later life (bugg et al)
what is crystal intelligence (Gc)
knowledge that increases over life time
how does Gf and Gc change over a lifetime
fluid intelligence peaks early in life and then declines
is IQ heritable
heritability accounts for between 48-80% of the variability in IQ scores
what is an issue with the heritability of IQ
assumes that fluid intelligence is fixed and crystallised intelligence is not
what is spearman’s hypothesis
racial IQ differences are genetic in origin
what are eysenck’s hereditarian views on race
highly controversial - IQ is heritable, but there is no significant genetic determination of racial differences in IQ
what is the flynn effect
generation rise in IQ by average of 10 percentage points
stronger in adults than children
highest in netherlands, below average in UK
what environmental changes produce large changes in IQ
social multipliers
averaging
gene-environment matching
what did rindermann et al find regarding social multipliers contributing to IQ increase
internet and access to info
gaming
TV
education
nutrition
rising standards of living
how does “gene environment matching” contribute to an IQ increase
people seek out environments that match their phenotype
therefore, environment increases genetic / biological ability
