9.2 theroies of intelligence Flashcards
charles spearman
intelligence should be though of as a single trait
-factor analysis
factor analysis
uses correlations among many items to sort related variables into clusters called factors
General intelligence factor (g)
the blue ovals represents children’s performance on different academic subjects that are correlated to justify thinking that one factor called g, underlies them all
things that are correlated with (G)
-the general intelligence factor (G) as measured by IQ tests, has a .50 correlation with high school and university grades also positively correlated with: -lifetime earnings -Number of years of education -lifespan -perceptual judgment speed -capacity for impulse control -success in finding a job
things that are correlated with g
performance on IQ tests provide the BEST PREDICTOR OF ALL for an individuals workplace productivity after they are hired into a job
low g scores are correlated with
getting divorce
living in poverty
being incarcerated for a crime
problem with the correlations is that
we dont know the cause or relationship
-motivation to achieve leads to positive outcomes
g is not perfectly correlated with different academic skills
diff ppl have diff strength and weaknesses
doesn’t measure all the ways a person can capture intelligence
s
the part of children’s performance on diff academic subjects that dont correlate with one another spearman called s
-theres are the individuals subject-specific levels of intelligence
Louis Thurstone
seven primary mental ability underlying g
-g is made up of 7 clusters that are correlated with one another rather that independent of one another
-they are both distinct and related to one another
word fluency
reasoning
memory
verbal comprehension
numeric abilities
spatial visualization
perceptual speed
hierarchical model of intelligence
- the top is g
- the middles has 7 primary mental abilities
- the bottom has subject-specific intelligence
- based on more specific mental abilities
g can also be thought of as a combo of:
fluid intelligence (Gf) crystallized intelligence (Gc) -a persons fluid intelligence can affect their crystallized intelligence fluid intelligence declines as a we age but crystallized stays with us
fluid intelligence (Gf)
the ease by which we can learn new info and find solutions to unfamiliar problems
crystallized intelligence (Gc)
our ability to use our past experience and knowledge we have already acquired to complete tasks
Robert Sternberg
tried to capture forms of intelligence that was different than the ones that promotes success in academic settings
