Two kinds of WISC-R short forms, item reduction and subtest reduction, are reviewed in terms of their ability to meet these criteria of adequacy: a significant correlation between the full scale IQ and the short form IQ, a non-significant difference between the full and short form mean IQ, a low percentage of IQ classification changes resulting…

Recent discussions of sex differences in intellectual abilities concur that such cognitive sex differences are statistically reliable yet small. To examine the variables of anxiety, rigidity, and divergent production, and to demonstrate that meaningful interactions involving the sex variable may be revealed when there are no "simple" sex…

The intended end product of the research project described is an "intelligent" multimedia tutoring system for procedural tasks, in particular, the repair of physical objects. This paper presents the data structure that will be used, i.e., a graph with five types of nodes (mental, abstract, motoric or action, visual, and verbal) and two types of…

The relationship between cognitive psychologists and researchers in artificial intelligence carries substantial benefits for both. An ongoing investigation in causal reasoning in medical problem solving systems illustrates this interaction. This paper traces a dialectic of sorts in which three different types of causal resaoning for medical…

Intelligence quotient (IQ) differences among groups according to sex, and demographic and other variables have been explored for a variety of intelligence tests. This investigation analyzed data from the standardization sample for the 1981 Wechsler Adult Intelligence Scale-Revised (WAIS-R) to determine the relationship of WAIS-R IQs to the…

Despite the naysayers, this old-fashioned idea that children can be taught still represents the most practical as well as the most soundly based element of the educator's creed. (Author/WM)

The portions of Inequality: A Reassessment of the Effect of Family and Schooling in America (Jencks, et al 1972) concerned with inequality in cognitive skills and estimating the heritability of IQ scores are reviewed. For related articles see TM 501 196-200. (MLP)

Eighty-three children (mean age 9 years) with learning disabilities or multiple physical or sensory handicaps were tested using the Peabody Individual Achievement Test (PIAT) and one or more standard measures of intelligence to assess the value of the PIAT as an effective measure and screening device of educational achievement.
