Document Summary
Intellect tests should assess high-level abilities (problem solving, reasoning, judgment) directly. Successfully identified children with difficulty were highly correlated w their school performance years later. Intelligence can be described at 3 levels of analysis: one thing, few things, many things. Single trait that influences all aspects of cognitive func. Performance on all intellectual tasks is positively correlated. Cattell said two types: crystallized and fluid intelligence. Fluid: ability to think on the spot: draw inferences and understand relations between new concepts, adaptation to novel task, speed of processing, working memory, ability to control attention fluid intelligence peaks at age 20-25 and slowly declines. Brain areas active also differ: fluid= prefrontal cortex; Thurstone: 7 primary mental abilities: word fluency, verbal meaning, reasoning, spatial visualization, numbering, rote memory & perceptual speed. Information-processing analyses of how people solve intelligence test items and how they perform everyday intellectual tasks: read, write, arithmetic. Allow more precise specification of the mechanisms involved in intelligent behaviors.
