Intelligence Testing issues Flashcards
Spearman’s two-factor theory predicts that performance on any cognitive task depends on___plus one or more specific abilities.
g(general intelligence)
Horn and Cattell differentiated between fluid and___intelligence and concluded that___intelligence is strongly affected by education and cultural experiences.
crystallized; crystalyzed
Sternberg’s triarchic theory proposes that successful intelligence is composed of 3 abilities: analytical,___, and____.
creative;practical
The impact of heredity on intelligence is demonstrated by studies showing that, the greater the___similarity between people the higher the correlation coefficient ebtween their IQ test scores. For example, the correlation for identical twins reared together is about____, while the correlation for biological siblings reared together is ___.
genetic; .85;.45
The influence of the environment on intelligence is demonstrated by research on the___effect which found (with some recent exceptions) a steady increase in IQ test scores in the US and other industrialized countries.
Flynn
With regard to the stability of intelligence over the lifespan, Horn proposed that crystalized intelligence increased until about age___, while fluid intelligence peaks in late adolescence and tehreafter declines.
60;
Research investigating the stability of intelligence over the lifespan has produced contradictory results, in part because of the different research methodologies used. Early age-related declines are most likely to be found when a___design is used because this design is very susceptible to__effects.
crosssectional; cohort(intergenerational)
Schaie and his colleagues used a__design and found that, of the six mental abilities they assessed, only___showed significant declines prior to age 60.
cross-sequential; perceptual speed
Males and females do not differ in a consistent way in termsof mean scores on IQ tests, but females tend to outperform males on measures of__ability whilemales obtain higher scores on measures of certain___ and math skills.
verbal; spatial
Several experts argue that cognitive ability tests are biased against members of certain groups. They distinguish between___bias, which occurs when there is differential validity, and intercept bias, which occurs when mean scores on the_differ for different groups.
slope; predictor
