Chronometric methods of cognitive assessment of learning disabled students which measure speed of response to elementary cognitive tasks requiring minimal prior knowledge are discussed. Chronometric techniques known to correlate with IQ and other indexes of mental efficiency and scholastic proficiency are described. (Author/DB)

The author examines claims that the Kaufman Assessment Battery for Children (K-ABC) is less culturally biased than other standard tests of intelligence. He concludes that the diminished Black-White difference for the K-ABC is largely the result of psychometric and statistical artifacts. Implications for future test construction are noted.…

Based on a paper presented at the American Educational Research Association Convention (Annual, Chicago, Illinois, February 8, 1968).

None of the several objective indices of cultural bias shows any significant indication of bias in any of the standardized tests of intelligence examined when they are used with blacks and whites. (Author/IRT)

The culture loaded Peabody Picture Vocabulary Test (PPVT) and the culture reduced Raven's Progressive Matrices (Colored and Standard forms) were examined and compared for large samples of white, black, and Chicano school children, K-8, in three California school districts. On both the PPVT and the Raven's the three ethnic groups show large mean…

Charles Spearman originally suggested in 1927 that the varying magnitudes of the mean differences between whites and blacks in standardized scores on a variety of mental tests are directly related to the size of the tests' loadings on g, the general factor common to all complex tests of mental ability. Several independent large-scale studies…

In this address, Jensen discusses his views on the effects of heredity and environment on human intelligence, in an attempt to clarify his original statements on this subject. Since his article appeared in the "Harvard Educational Review" in 1969, the term "Jensenism" has accrued a variety of meanings through popular usage (according to Jensen)…

Longitudinal data on the auditory forward and backward digit span (FDS and BDS) subtests of the Wechsler Intelligence Scale for Children (WISC) were obtained at five age levels (between 6 and 13), in samples of white and black children. Factor analysis and analysis of variance of the data were conducted to test 5 hypotheses, related to Jensen's…

This paper, focusing on differences between Caucasians and Negroes in the United States, summarizes from a "scientific standpoint" the main facts and theoretical issues involved in the study of human racial differences and behaviors. Three principles are considered to govern the orientation of this document: (1) objective research and…

The several statistical methods described for detecting test bias in terms of various internal features of a person's test performances and the test's construct validity can be applied to any groups in the population. But the evidence regarding groups other than U.S. blacks and whites is either lacking or is still too sketchy to permit any strong…

Discussed are the theoretical explanations of the observation that low intelligence quotient (IQ), low socioeconomic status children appear to be brighter in certain ways than low IQ middle class youngsters. The two different theories on IQ as a function of socioeconomic status--environmental or cultural vs. genetically determined biological…
