Suggests an alternate, and optimistic, interpretation of developmental data that has been interpreted as indicating cumulative deficit in IQ among socioeconomically deprived Black children. (Author/SS)

Desegregated students showed greater gains in reading achievement at the end of 7 months than segregated students; however these differences may be due to qualitative differences in reading instruction and do disappear after 24 months. Black students I.Q.'s increased under conditions of desegregation while students in the control school lost…

Arthur Jensen has argued that genetic differences in abstract reasoning ability, not cultural bias in the test item, are the causes of differences in standardized test performance between American Blacks and Whites. He used a study by Frank McGurk to support his argument. McGurk's study used test items judged most cultural or least cultural. These…

Colleges must not admit all who apply in order to find the talented tenth by the process of elimination. What is wanted are students with potential who can progress by their own merit alone or with help. (Author)

The Revised Wechsler Intelligence Scale for Children appears significantly to widen the gap between Black and White performance, increasing the likelihood of unjustified negative social and educational consequences. (Author/EB)

One hundred eighty one sets of black twins and 223 sets of white twins provided responses to four 12-item subtests of the Raven's Progressive Matrices Test, Standard Version. The children were in elementary school and their item response patterns were analyzed with the use of revised ordering-theoretic methods to search for best-fitting…

In a study in which Asian-American, white, and black children in grades 2-6 in a California school district were given a battery of tests including measures of IQ, scholastic achievement, and short-term memory, factor analysis of the tests yielded two main factors identified as Level I (memory) and Level II (general intelligence) in Jensen's…

Until the 1970s, there were few signs of change in the historic difference of one standard deviation between average ability or achievement test scores of black and white students. From 1970 to the mid-to-late 1980s, there was a substantial convergence of the average achievement test scores of blacks and whites. From the mid-to-late 1980s to 1992,…

This report is a summary of a doctoral dissertation at the University of Oklahoma by the first author, under the direction of the second author. (RJ)

Groups of 270 Black and 270 White children drawn from the national stratified random sample used in the standardization of the Wechsler Intelligence Scale for Children-Revised (WISC-R) were matched on age, sex, and WISC-R Full-Scale Intelligence Quotient to facilitate investigation of the patterns of specific cognitive abilities.

Compared the factoral structure of the Wechsler Intelligence Scale for Children-Revised (WISC-R) for Anglo, Black, and Mexican-American children. Found high similarity across groups. The order of subtest difficulty was significantly correlated with subtest g loadings for Mexican Americans. Results provide support for Spearman's hypothesis with…

Cumulative deficit is an hypothesis concerning the cause of lower mental test scores of groups considered environmentally deprived. It presupposes a progressive decrement in test scores, relative to population norms, as a function of age. Clarification of the theoretical issues and the methodological problems involved in establishing the…

Borkowski and Krause (1983) concluded that the locus of black-white intelligence differences lies in metaprocesses not elementary cognitive processes. However, some variables were difference scores with unacceptably low reliability. Magnitude comparisons of racial differences give a different picture of results; comparable differences in measures…

Jensen (1985) caused us to reexamine earlier findings. After correcting perceptual efficiency and executive systems measures for unreliability, original conclusions remain tenable. Control processes are factors in understanding race-related differences in intelligence. We do not deny the association of "speediness" but argue for a multidimensional…
