Developmental differences in reasoning ability and item processing demands are analyzed in a study of cognitive determinants of number analogy performance in two IQ levels of elementary school children and college students. The amount of solution-related information in working memory was the crucial processing demand. Process differentiations of…

This training study examined the modifiability of older adults' (n=73) performance on measures of attentional processes and training transfer to the psychometric ability domains of perceptual speed, memory span, and fluid-crystallized intelligence. Significant training effects occurred for attention measures, and these effects were maintained at…

While for 31 trainable mentally handicapped children and for 31 nonhandicapped, there were no differences in static balance on left or right legs, total balance time was significantly different between the two groups. This confirms prior work which related motor proficiency to intelligence. (Author/RD)

Presents findings from study of design activities among 26 novice instructional designers which investigated prevalence of initial generation of more than one design solution; basis on which solutions are accepted or rejected; constraints encountered in proceeding with design; way in which designers know design is finished. Twelve references are…

Investigated the utility of profile analysis, using the Wechsler Intelligence Scale for Children--Revised (WISC--R) to differentiate learning disabled from emotionally disturbed and nonhandicapped children. Little evidence supported the use of WISC--R subtest scatter. Research efforts focused on WISC--R subtests related to the learning process are…

Using Locus of Control in Three Achievement Domains (LOCITAD), this study examines differences in locus of control orientation for 80 Anglo, 80 Black, and 44 Chicano high school students with respect to success and failure in three domains--intellectual, social, and physical. (Author/MP)

Two groups of disabled readers, ages 8 and 11, were tested. Perceptual abilities related more strongly for younger students, while intelligence related more strongly for older students. Questions are raised about the validity of using expectancy formulae with younger disabled readers and the "learning disabilities" approach with older disabled…

Reviews some better known Piagetian scales; analyzes and compares Piagetian-based and conventional intelligence measures. Reviews research comparing the two methods and examines whether racial groups' performance differs on Piagetian measures. Discusses the implications of Piagetian assessment procedures for school psychologists. (Author/RC)

Children and adolescents who had positive Dye Tests for toxoplasmosis had lower performances on all verbal subtests than those with negative Dye Tests. The impairment was comparable to subjects with brain damage. Subjects with congenital sight deficiency and positive Dye Tests showed progressive intellectual impairments. (Author/CM)

Testing, both in childhood and as adults, of 28 former pupils of special schools for the educable mentally retarded indicated that pupils who experienced most serious problems in childhood were less retarded as adults than persons who had experienced few or no problems. Results support hypothesis that the effects of early lack of environmental…

Tested parochial school students with an examiner who wore a moderately proportioned gold cross, a gold Star of David, or no symbol. Results indicated scores varied as a function of the presence and type of symbol that was displayed. Discusses implications for practioners. (Author/JAC)

Reported is a study designed to investigate the relationship between science attainment and intelligence as well as differences between the performance of boys and girls in physical science. (PB)

Discusses four ubiquitous major sources of measurement error for individual intelligence scales. Argues that where these sources cannot be directly investigated, they should be estimated rather than ignored. Estimated the typical magnitude of error arising from each of content sampling, time sampling, scoring, and administration. (Author)

Adolescents from one inner-city, two suburban, and one private school were tested using the Washington University Sentence Completion Test of Ego Development. Both test-retest correlations and change scores supported the hypothesized sequence of ego development. Significant correlation between ego level and intelligence occurred in two schools.…

By drawing analogies to the history of mental testing, the author concludes that the responsibility for critical evaluation and beneficial use of social indicators rests with social scientists. Future directions of critical inquiry are suggested. (Author/MH)
