This editorial suggests how the approaches of differential psychology and information processing psychology should be combined to study intelligence. Methods reviewed include factor analysis, componential analysis, and computer simulation. Guidelines for the specification of subtheories of intelligence, as well as future theories and methods for…

Results indicated that extrinsic rewards improved students' test performances significantly more than no rewards or feedback reward conditions. These improvements in performance were noted for all students under extrinsic reward conditions, thereby extending the effectiveness of these procedures across IQ levels. (Author/CL)

Analysis of the mental factors of seventh grade students indicates that numerical facility and perceptual speed are a single factor at this age level and that no purely verbal factor exists. Seven clearly differentiated factors are found for males and five for females. (Author/WY)

The question as to whether males and females have different kinds of intellectual abilities is addressed. The evidence that there are some differences in cognition and perception between men and women is reviewed. (KR)

This paper examines the implications of recent theory and research in cognitive psychology for the understanding and assessment of intelligence. Three major themes are developed. The first has to do with how changes in the social and educational climate for testing can influence the conception of intellectual compentence and the technology of…

Examines the definitions of intelligence and educability and discusses these terms in relation to the writings of Jensen and of Darlington. (PEB)

Item responses of two samples each of 622 normal and 573 educable mentally retarded children, 6 to 15 years of age, on Raven's Colored Progressive Matrices were submitted to a principal components analysis and varimax rotation. The following four factors were obtained: continuity and reconstruction of simple and complex structures, discrete…

Available from: Journal of Pediatric Psychology, Child Study Center, 1100 N.E. 13th Street, Oklahoma City, Oklahoma 73117. Compared in intelligence, perceptual motor performance, and academic achievement were 30 children (mean age=8.6 years) with seizure disorders and 30 children (mean age=9 years) with learning problems.

The relationship of test wiseness to I.Q. and the usability of I.Q. scores are discussed. Test wiseness involves the examinee's ability to obtain a high score on a standardized achievement test as a result of utilizing test-taking experience. Usability of I.Q. scores refers to the value of I.Q. scores to educators in making educational decisions.…

Tests were administered to 209 educable mentally handicapped children (mean age 10.8, mean IQ 77) to determine factors related to speech hearing. Results indicated that mental age, intelligence quotient, physiological age, institutionalization, and organic bases for retardation were not significantly related either to speech reception threshold or…

Three conditions for administering creativity tests by Torrance and by Wallach and Kogan were compared: (1) untimed, gamelike; (2) conventional testlike; and (3) administration of measures under testlike conditions on two adjacent days, using the second testing as the predictor. The conventional testlike condition seems optimal. (Author/CP)

A chronicle of controversies over testing (heredity-environment, experimenter bias, social class bias, tests as sorters for schools and society) and the difficulties that ensue when the scholar enters the arena of public policy. The thesis is offered that the hearing given to social evidence and issues depends on the times and the audience, with…
