chapter 9.2 Flashcards
is intelligence a single, general ability?
no
who is charels spearman?
he began by developing techniques to calculate correlations among multiple measures of mental ability
what is an example of charels spearmans test?
scores on tests of vocabulary, reading comprehension and verbal reasoning correlate highly together and would form a factor we might refer to as verbal intelligence
what were the 2 types of independent abilities that created the overarching ability of intelligence?
math and language abilities
what did spearman hypothesize?
general intelligence factor (g)
what is the general intelligence factor?
a persons mental energy, reflecting spearmens belief that some people brains are simply more powerful than others
do measures of general intelligence tell the whole story?
no, they do not tell us much about how intelligence works, only whether people tend to do well on various types of tasks
what is one explanation as to why general intelligence does not tell the whole story?
because people each possess individual skills that cause for some variability in the general intelligence testing
to account for this specific skill set impacting general intelligence, what did spearman do?
created “S” to represent specific level, skill based intelligence
what was the 2 factor theory?
intelligence was comprised of general intelligence (g) and skill or ability level for a given task (s)
what was the first influential theory of multiple intelligences?
a theory created by Louis thurstone who examined scores of general intelligence tests and using factor analysis found 7 clusters of primary metal abilities
what are the 7 primary mental abilities?
word fluency
verbal comprehension
numeric abilities
spatial visualization
memory
perceptual speed
reasoning
what settled the controversy of two factor intelligence models?
the potion of hierarchical models that describe how some types of intelligence are nested within other in a similar manner
what does the general hierarchical model describe?
how our lowest level abilities are nested within a middle level that roughly corresponds to thurstones primary mental abilities and those are nested within a general intelligence
what does the general hierarchical model show?
that general intelligence is made up of a small number of sub-abilities, each of which is made up of a large number of specific ability that apply to individual tasks
