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…

Disparities between European countries and the U.S. in terms of incidence and prevalence of mild mental retardation have become apparent. A model of intellectual performance that might explain disparities and predict future levels of occurrence of mild mental retardation is presented. Such explanations are relevant for theory and policy decisions.…

Whether "psychometric" and "Piagetian" kinds of intelligence are similar is a question of whether they have similar courses of development with age. When using factor analysis to address this issue, age effects must be eliminated in order to assess relations among measured constructs. Reanalyses of previous results were…

Ramey and Haskins report two findings of major importance: absence of decline in test scores and absence of mother-child correlation for treated children. Implications of these findings are discussed. (Author)

Results from the Colorado Adoption Project, a longitudinal study initiated in 1975, are reported. The cognitive ability of parents and measures of one-year olds' mental development were significantly correlated for all three parent/child comparisons. Caldwell's HOME Responsibility measure was correlated with infant intelligence in adoptive and…

Asian-American, White, and Black Children in grades 2-6 were tested for intelligence, achievement, and short-term memory. Factor analysis yielded two main factors: memory and general intelligence. The three groups differed distinctly at every grade level. Achievement correlated more with memory than with general intelligence. (Author/CP)

Inspection time (IT) and Peabody Picture Vocabulary Test (PPVT) scores from 75 school children aged 6-13 years in 2001 were compared with the performances of 70 children aged 6-13 years who had attended the same primary school in 1981 ["J. Exp. Child Psychol." 40 (1985) 1.]. ITs for the 2001 sample were measured with the same four-field…

The purpose of this research was to study the correlation between socioeconomic status and intelligence. The Project Talent Data Bank was used in the study. The measures of privilege/deprivation developed show some degree of differential abilities and the measures of intellectual privilege are almost cogeneric measures of general intelligence.…

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…

Relationships among Piagetian reasoning assessments and standard measures of intelligence and achievement were determined in 1972 by Stephens, McLaughlin, Miller, and Glass (EJ 055 112). The data were reanalyzed by Humphreys and Parsons in 1979 (EJ 218 642). In reply, Glass and Stephens note fallacies in Humphreys' and Parsons' reasoning.…

Raw scores on WISC-R subtests and the verbal, performance, and full scale IQ scales were correlated with age separately for White and Black males and females. The relationship between age and intelligence test performance was constant across race and sex and supports the construct validity of the WISC-R. (Author/RD)

This book focuses on topics germane to cognitive abilities viewed from a "minority psychology" perspective. The most contentious chapters concern test bias and heredity, with culture, socioeconomic status, and case viewed as the chief explanations for test score differences between social classes and racial and ethnic groups. The reviewer…

Intellectual abilities were measured for 217 German and 205 American college students using tests (in the subjects' native languages) in which equivalence was established by an item-response theory-based differential-item-functioning (DIF) analysis. Comparisons between groups were not the same before and after removal of DIF items. (SLD)

In a computerized video-game-like spatial ability measure administered to 94 university students, the number of target hits was correlated with verbal intelligence quotient. The dynamic spatial measure does not load substantially on a general intellectual ability factor, but it does provide additional evidence that dynamic spatial ability is…

Change in cognitive functioning is an important aspect of human aging and a key outcome in many medical conditions. However, cognitive change can rarely be measured directly, since prior cognitive data do not exist for most people. We examined the criterion validity and one-year stability of the difference between National Adult Reading Test…
