identifying kids who needed special help at school

the test was very successful at predicting...
school success because it tested abilities needed at school
complicated statistical procedure that combines scores from separate test items into several factors, which can substitute for the separate scores
noticed people who scored high on some test items tended to score high on others as well; he concluded the test items were measuring an underlying general intelligence (g)
Spearman and g
Spearman noticed test items measured different specific abilities (s), but believed g was the _____
central aspect of intelligence that deserved attention
Rejected the idea of "general intelligence" identifying 7 mental abilities

Crystallized vs. fluid intelligence
culturally-loaded, fact-oriented information;
ability to see complex relationship and solve problems
because crystallized intelligence is impacted by ____, this type of intelligence ____ across the lifespan.
Fluid intelligence may not be impacted by experience. It is believed to peak in ____ adulthood and gradually ____ thereafter.
formulated 3 components of intelligence
Sterberg's triarchic theory of intelligence
mental abilities typically measured by traditional IQ tests (e.g. knowledge, cognitive strategies)
creativity and quick learning of new tasks so they become automatic
practical intelligence (e.g. adapting on'es kills shaping a situation to meet on'es needs, or changing contexts)
this aspect of intelligence is strongly affected by culture (e.g. street smart, common sense)
denied a g factor and proposed 8 independent, equally important forms of intelligence

correlations between gardners 8 forms of intelligence would be quite _____, a person can have very high ability in one area and very low in others
there is _____ support for gardner's theory of multiple intelligence (i.e. damage to a specific brain region only influences specific abilities)
Researchers point out the differences between tests that are:

Stanford-Binet intelligence scale if for what age group?
2 years to early adulthood
standfor-binet intelligence scale 5th edition includes 15 subtests that combine to provide a General IQ score and 5 factor scores:

Wechsler that is available for preschoolers?

- 4 factor scores (verbal reasoning, perceptual reasoning, working memory, and processing speed)
What does the WISC-IV allow identification of?
strenghts and weakenesses
Components of Good tests
the test must consistently yield the same score when people are tested repeatedly (or almost the same)
the test must measure what it is inteded to measure. Does it correlate wit other IQ tests? Does it correlate with oter abilities/aptitudes with which it should be related?
establishing norms for comparing scores of people who will take the test in the future; administering the test to many people also allows for the development of the administration procedures
