A procedure was presented that would allow true estimates of the effectiveness of intervention programs when the WPPSI is used as the evaluative measure. (Author)

An examination of the historical record fails to uncover any support for the claim that the racially biased Immigration Act of 1924 was passed with the help of the intelligence testing community. (GC)

This article describes the author's courtroom experience as a witness for the defense in the Larry P. v. Wilson Riles case; provides excerpts of the testimony and cross-examination; and makes suggestions for individuals who may testify as expert witnesses. (Author/BW)

Factor scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) were compared for two groups (total N=100) of cultural-familial mentally retarded youth (eight- to 11- and 13- to 16-year-olds) and one group of 50 nonretarded youth (eight- to 11-year-olds). (Author/SW)

Argues that despite aberrations, false starts, misapplications, and unfortunate crystallizations of methods and interpretations, the differential psychology of cognitive abilities is an important part of psychological knowledge about human beings. (Author/GC)

Results of this study indicated that positive feedback was more accepted than the negative feedback. Females as compared to males evidenced less desire for further feedback after receiving negative feedback, while the reverse was true after receiving positive feedback. Personality feedback as compared to intellectual feedback generated a stronger…

Investigated robustness of the Wechsler Intelligence Scale for Children-Revised (WISC-R) factor structure. Comparisons of the loadings obtained with generalization sample and 10 1/2-year-old national standardization sample suggest high degree of similarity in composition, magnitude, and pattern. Findings highly support robustness of WISC-R's…

Results tend to agree with previous general population samples in not indicating any significant association between total IQ and season of birth. (Author/DB)

Because no single characteristic defines intelligence, there can be no adequate process-based definition of intelligence. In principle, a combination of many empirically derived measures into a single index, as in a Binet test, would be appropriate. In practice, many of the relevant characteristics are simply impossible to measure. (Author/RD)

The validity of the Slosson Intelligence Test (SIT) relative to the California Short Form Test of Mental Maturity and the Shipley-Institute of Living Scale was investigated on a sample of college students. Results supported the validity of the SIT. (Author/JKS)

The issue of factor indeterminacy in factor analysis has been the subject of considerable debate in recent years. The same issue was also discussed widely in the 1920s and 1930s. The history of the issue, the literature on the subject, and parallels between early and modern work are discussed. (Author/JKS)

Four models of intellectual abilities were evaluated using confirmatory factor analysis and data from 197 children referred for a gifted program who took the Kaufman Assessment Battery for Children (K-ABC). All four models were a possible fit, but the best understanding came from a model posited on a theory of fluid-crystallized abilities. (SLD)

Studied whether mediated learning experience would improve the scores of African students on Raven's Standard Progressive Matrices. Seventy African and 28 non-African college students in South Africa were given the Raven's Progressive Matrices on 2 occasions, and some subjects were exposed to the mediated learning experience. Both groups improved…
