Issues pertaining to racial-ethnic differences in intelligence are addressed with regard to group-discrepancy misconceptions, profiles of abilities, historical context, factors associated with racial-ethnic differences, educational implications, and alternative methods of assessment. (Author/MMU)

Examines various assumptions that underlie current definitions guiding the assessment of gifted and talented students, making suggestions reflective of the synthesis of available constructs defining gifted education. Implications of these assumptions for assessment (primarily identification) of gifted and talented students are noted. Using types…

Purpose of mini-series is to present current conceptualizations of the structure of intelligence, new research on human cognitive abilities and their interpretations, and pertinent, practical considerations regarding the use of intelligence tests in schools. Discusses educational-policy issues as well as diagnostic and treatment-utility issues.…

Examines WAIS-R profiles of 194 college students diagnosed with learning disabilities (LD) to assess where they yield unique and interpretable profiles. Results show nearly 94% match profiles found in the WASI-R standardization sample. Also, shapes fail to explain a significant proportion of variation in student academic skills. (Author/JDM)

Reviews the use of IQ scores in determining special education placement. It argues that although IQ is central to state education codes and their eligibility criteria for special education, the evidence shows that many children exhibiting psychometric scores that would make them eligible are never referred. (Author/CR)

The D-48, a nonverbal test of general intelligence, was administered to 250 Mexican American and Anglo American community college students. Analysis of D-48 scores indicates no significant differences due to ethnicity or gender; adequate internal consistency and test-retest reliability; and significant correlations with grade point average and…

Investigates the stability of the Stanford-Binet Intelligence Scale: Fourth Edition (SB:FE) and the Kaufman Assessment Battery for Children (K-ABC) by testing a sample of 65 children from low socioeconomic status families. Mean scores for the group were roughly equivalent, correlation coefficients were high, and change scores for the majority of…

Comparison of 26 hospitalized psychiatric youth with attention deficit-hyperactivity disorder (ADHD) with 27 similar youth without ADHD on the "Freedom from Distractibility" factor of the Wechsler Intelligence Scales for Children III found no significant intergroup differences, thus concluding that this factor is not a valid discriminant…

Investigation of criterion-related validity of test scores of 107 deaf residential adolescents found concurrent validity between the Standard Progressive Matrices (SPM) and the Performance IQ of the Wechsler Intelligence Scale for Children-Revised, using both hearing and deaf norms. Predictive validity was supported by correlations between the SPM…

Argues that Herrnstein and Murray's "The Bell Curve" (1994) merely restates the notion that intelligence can be reduced to a single ordinal measure, i.e., the primary factor for determining group or individual social-class status. Evidence from the biological sciences and quantitative genetics is presented that reveals that social…

The third edition of the Wechsler Intelligence Scale for Children (WISC-III) is reviewed. A comparison of the WISC-III with the Weschler Intelligence Scale for Children-Revised (WISC-R) is included. Discusses shortcomings of the WISC-III while noting that overall, there are substantial improvements in the WISC-III over the WISC-R. (KW)

Aging patterns in WAIS-R Block Design Test (BDT) were examined cross-sectionally and longitudinally. One sample (35-80 years, n=1000) was assessed in 1988-1990 and five years later (836 returned). An independent cohort-matched sample (n=974) was assessed at Time 2 to control for practice effects. Relations between BDT, gender, and education were…

The purpose of this study is threefold. First, an estimate of state IQ is derived and its strengths and limitations are considered. To that end, an indicator of downward bias in estimating state IQ is provided. Two preliminary causal models are offered that predict state IQ. These models were found to be highly predictive of state IQ, yielding…

It is unclear whether brain mechanisms underlying human intelligence are distributed throughout the brain or mainly concentrated in the frontal lobes. Data are inconsistent possibly due, at least in part, to the different ways the construct of intelligence is measured. Here we apply the method of correlated vectors to determine how the general…

A number of studies in the United States have found that Jews obtain higher average IQs than white gentiles. This paper examines whether this is also the case in Britain. Three early studies are summarized that found that Jews in Britain have mean IQs in the range of 110-113. New data are presented for two nationally representative samples of 7-16…
