Mental test data cited by H. T. Epstein as supporting his theory that new concepts should be taught during periodic spurts in childhood intellectual development (at 3-10 months; and 2-4, 6-8, 10-12 or 13, and 14-16 or 17 years) are reanalyzed. It is found that the data do not substantiate Epstein's conclusions. (TJH)

The importance of defining variables to be put into correlation tables for factor-analytic research into intelligence is discussed. Research on job analysis, task decomposition, performance-related intelligence changes, and cross-cultural differences could be incorporated into definition of variables. (TJH)

Cognitive processes underlying the empirical correlation between IQ and choice reaction time (CHRT) were examined using the Culture Fair Intelligence Test and nine CHRT tasks (N=50 university students). IQ predicted well for simple control tasks and available attention, but not for attention flexibility, feature extraction, or response choices…

Discusses the need to develop ways of measuring the cost effectiveness of investment in employee training. Examples of employees with various training needs and their possible impact on the organization are presented, the replacement of humans with machine intelligence is discussed, and the application of performance technology is suggested.

Investigated validity of Stanford-Binet Intelligence Scale-Fourth Edition and Kaufman Assessment Battery for Children with 89 preschool Head Start children from low-income families, using Stanford-Binet Intelligence Scale-Form LM as criterion measure. Found some support for concurrent and construct validity of both instruments for use with…

Studied 622 adults and 211 undergraduates to determine the relationship of perceptual speed and speed of marking psychometric answer sheets to individual differences in performance on psychometric tests. Findings suggest strong relationships between age, speed, and intelligence-test performance. (RJC)

Discusses the use of computers to help with problem solving. Topics include information science, including effective procedure and procedural thinking; templates; artificially intelligent agents and expert systems; and applications in education, including the goal of computer literacy for all students, and integrated software packages such as…

The four-part Teaching for Understanding framework covers the full range of intellectual disciplines. Different disciplines call upon different analytic styles, problem-solving approaches, and findings, temperaments, and intelligences. This article explores stages of student development, ranging from intuitive, common-sense theories about the…

Discussion of a prototype intelligent education system called WOMBAT (Weighted Objectives Method by Arguing with the Tutor) focuses on dialogue and negotiation in collaborative problem solving. The results of a formative evaluation, in which the system was used by 10 subjects who commented on various aspects of the design, are presented. (Contains…

Describes an intelligent computer-assisted learning system that is able to generate individualized courses of instruction for students with different background knowledge and different purposes. Highlights include system architecture; domain knowledge base and student model; authoring by the teacher; courseware planning; and pedagogical tuning by…

Criticizes the computer modelling experiments conducted by Sokolik and Smith (1992), which involved the learning of French gender attribution using connectionist architecture. The article argues that the experiments greatly oversimplified the complexity of gender learning, in that they were designed in such a way that knowledge that must be…

Examined gender differences in cognitive outcome in children born prematurely who had incurred early cerebral lesions and in a high-risk comparison group. A significant gender difference in cognitive recovery was observed in the lesion group. Girls outperformed boys on standardized intelligence tests. No gender differences were observed in the…

Like the "scientific" approaches of craniometry and eugenics, Herrnstein and Murray's methods and arguments reveal an ideological position not only on African Americans but also on the role of women. Points out their focus on women in discussions of "illegitimacy," birth control, and parenting, and their targeting of poor…

Responds to J. P. Rushton's contention that blacks are small-brained, oversexed criminals who multiply at a fast rate and are afflicted with mental disease. The author shows Rushton's views have virtually no scientific basis and were arrived at through unscientific methodology and literature based on racist prejudice. (GR)

The 1992 definition of mental retardation recently written by the American Association on Mental Retardation replaces designated levels with intensities of needed supports to facilitate an individual's functioning across environments. This article critically analyzes this new definition and discusses several challenges it presents to school…
