Recent developments in the concept of intelligence are discussed in light of experimental evidence. The concept of a general theory of intelligence is defended as necessary to explain much empirical data. Any adequate theory of intelligence must take its threefold nature (biological, psychometric, and social) into account. (SLD)

Gifted (N=127) and nongifted (N=116) students (ages 12-17) completed a questionnaire that asked their views of the concepts of intelligence. Despite many substantial differences, both groups tended to view intelligence as arising from hard work and good attitudes. Gifted students also tended to rate their own intelligence accurately.

Results from analyses of sex ratios as a function of IQ are presented for 623 autistic children and 506 nonautistic communication-handicapped and behavior-disordered children. Proportionately more autistic females were found to have IQs of 34 or below than above 34. However, a linear trend of an increasing number of males with increasing…

Dyslexics and normal readers aged 9-11 were compared on an inspection time task. Results indicated that dyslexics required significantly longer inspection times than did normal readers. Dyslexics exhibited relatively greater individual variation and benefited from practice. (Author/RH)

The accuracy of Payne and Jones's (1957) formula for evaluating the abnormality of test score differences was checked against the actual distribution of discrepancies in the standardization sample for the Wechsler Adult Intelligence Scale-Revised. The results appear sufficiently accurate for most clinical applications and support the formula's use…

The author traces the history of defining giftedness and asserts that, despite the controversy, general intelligence, as measured on a standardized intelligence test, still provides the best single, reliable predictor of academic aptitude, task commitment, and creativity. (CL)

Arthur Jensen replies to the critique by Steven Selden. He points out that scientists' choices of subject matter are subjective, but heritability of intelligence is no longer argued among experts. (MD)

Demonstrated that equally weighting Wechsler Adult Intelligence Scale subtests that differ in validity reduces potential validity. Concluded that vocabulary and information in concert have greater validity than either subtest by itself and that the addition of a third test will not result in a consistent increase in validity.

The paper describes recent research investigating the relationship between speed with which individuals can execute basic cognitive processes and performance on tests of intelligence and mental ability. Results are discussed in terms of three properties of the working-memory system which limit the amount of information for simultaneous storing and…

Profile analysis refers to interpreting or analyzing the pattern of tests, subtests, or scores. The analysis may be across groups or across scores for one individual. This approach to analyzing data is being used by clinicians to help in the translation of the results of popular assessment instruments. This paper examines several examples of the…

One must be extremely careful about reaching decisions concerning the state of a child's cognitive development on the basis of the results of tests that are highly unreliable in their present form. (CK)

Under positive referral conditions testers obtained higher IQ scores, rated the child more favorably on Factors Affecting Test Performance and made more favorable recommendations than under negative referral conditions, thus supporting the hypothesis that the referral agent does influence the testing situation.
