Psych Exam 3 Study Guide Intelligence (Ch. 9) Criteria for Good Psychological Tests: Standardization: Testing, scoring, & interpretation procedures are consistent across all administrations of a test; well-standardized tests are administered the same way to every test taker, every time > every test taker has an equal chance to do well Norms: How someone scores relative to other people; record of prior test performance of large groups of people; have something to compare scores to Reliability: Produce similar results with repeated administration to the same person Test-retest: Getting the same result when the person is retested later Validity: How well a test measures what it is supposed to measure Content Validity: Does it sample broadly from the domain of interest? Predictive Validity: Does it predict a future outcome, such as job or school success? The History of Intelligence Testing: Galton: Carried out first attempt to develop an intelligence test >> Motivated by Darwin >> conducted batteries of sensory, physical, intellectual tests >> However: Scores were poor predictors of real-world performance Binet: French psychologist > Invented IQ in 1904 > Stanford-Binet test The Stanford-Binet: One of the most widely used intelligence tests > based on Binet & Simon’s original IQ test but has been modified & updated many times; purpose of original IQ test was to identity students with special educational needs > Binet & Simon developed an IQ test which measured memory, vocab, & perceptual discrimination & brought it to the U.S.; still used to test children’s IQs WAIS / Wechsler (developed WAIS): Wechsler Adult Intelligence Scale; Wechsler wanted to develop a test appropriate for adults that wasn’t solely dependent on language; has performance & verbal subtests; IQ scores derived from norms; one of the most widely used intelligence tests Reliability & Validity of IQ Tests: Test-retest reliability- up to about age 10, not unusual for scores to vary; high reliability among adults (r=.9); Validity: Different IQ tests (WAIS & Stanford- Binet) correlate with each other; these tend to correlate well with school performance, but not as well with broader measures of how a person adapts to environment Are IQ tests valid? >> NOT good measures of: Career success, motivation (comparing most successful me with least successful, motivation, not IQ made the difference), creativity (ability to generate ideas that are original, novel, useful), emotional intelligence (ability to perceive, understand, express emotion in useful, adaptive ways) Genetic & Environmental Influences on IQ:

Genetic Influences: Twin studies-- Compare IQ scores of twins separated through adoption > Fraternal twins (different genetics), Identical twins (identical genetics) > identical twins have more similar IQs than fraternal twins; people who share all their genes have extremely similar intelligence test scores regardless of whether they share experiences; suggest that genes play an important role in determining intelligence
