PSY 335 Lecture Notes - Lecture 14: The Bell Curve, Intelligence Quotient, Heredity
Document Summary
Developmental experts do not agree on a general definition of intelligent behavior, even among adults. Several approaches devised to investigate nature of individual differences in infant intelligence. Information-processing approaches to individual differences in infant intelligence. Suggest that infant information processing speed may correlate most strongly with later intelligence. Prior experiences, examples, cultural background, and experiences do have the potential to affect intelligence-test scores. Many educators suggest that traditional measures of intelligence are subtly biased. The issue of how cultural background and experience influence iq-test performance has led to considerable debate among researchers. The debate has been fueled by the finding that iq scores of certain racial groups are consistently lower, on average, than the iq scores of other groups. The issue is important because of its social implications. Average 15-point iq difference between whites and african americans is due primarily to heredity rather than to environment.
