A study of 33 elementary/middle school deaf children correlated Wechsler Intelligence Scale for Children-Revised Performance Intelligence Quotients (IQs) with Stanford Achievement Test-Hearing Impaired Edition (SAT-HI) grade equivalents and age-based percentiles. A second study of 64 children correlated nonverbal IQs from many tests with SAT-HI…

Tests causal models of verbal and performance IQ in 69 Mexican-American children of low socioeconomic status. Years of mother's education were correlated with IQ at 3 years and at 6 to 8 years, but traditional/nontraditional attitudes showed conflicting correlations over time. The adequacy of standarized IQ tests for this population is questioned.…

Concurrent validity testing of the Slosson Intelligence Test-Revised with the Stanford-Binet Intelligence Scale (Fourth Edition), involving 191 individuals (ages 5-69 and IQs of 36 to 110), found a high correlation between the two scales. However, the Slosson unsatisfactorily matched the Stanford-Binet's assignment of individuals to IQ categories.…

Maintains that even a cursory reading of "The Bell Curve" reveals a skewed methodology that deliberately ignores relevant data. Includes statistical tables illustrating the relationship between environmental factors and test scores. Contends that the basic purpose of "The Bell Curve" is to justify economic racism. (MJP)

The position that intelligence and achievement are essentially different measures of the same construct has often been referred to as a "jangle fallacy." Such a position challenges the present practice of placing children in learning disabilities programs based on a discrepancy between Intelligence Quotient (IQ) and achievement. This…

This study examined the concurrent validity and diagnostic efficiency of the Kaufman Brief Intelligence Test (K-BIT) with 75 elementary and middle school students with learning disabilities, who had been referred for triennial multidisciplinary re-evaluations. High and significant correlations were found between the K-BIT and the Wechsler…

To examine the validity of short forms of the Wechsler Intelligence Scale for Children-Revised (WISC-R), the WISC-R was first administered to 106 hospitalized psychiatric patients, aged 8-16. No subjects had a primary diagnosis of mental retardation or learning disability, and one-third were receiving psychotropic medication. WISC-R IQ scores…

The purpose of this study was to replicate previous factor analytical studies of the Wechsler Intelligence Scale for Children-Revised (WISC-R) employing children identified as gifted. However, rather than using the IQ criterion, a child's 11 WISC-R subtest scores were included in the analysis. Subsamples of gifted (as classified by local school…

This study evaluated the external validity of a measure of IQ subtest variability, the profile variability index (PVI), with a sample of 146 children referred for psychological testing. Correlation of PVIs on each intelligence test with achievement scores and indexes of discrepancy between actual and predicted scholastic achievement found…

This study examined patterns of nonverbal intelligence test performance of 11 preschool children with and 12 without specific language impairments. The study found group differences in relations among nonverbal cognitive skills. Results suggest caution in using nonverbal intelligence tests normed on nondisabled children with children having…

A study was conducted to examine the relationship of perceptual motor skills as measured by the Bender Visual Motor Gestalt Test to word recognition, oral reading, and silent reading. In addition, perceptual motor skill and auditory comprehension were compared as correlates of the three reading variables. Subjects were 60 primary grade students in…

To show the difficulty of eliminating test bias and to develop a methodology for distinguishing between the effects of prior knowledge and of skill development on reading comprehension, 207 eighth grade students from rural and urban areas were administered an 18-question reading comprehension test. Quantitative and qualitative effects of prior…

The percent and characteristics of children who produced invalid profiles on two different continuous performance tests (CPTs) tasks were examined. Sixty-one children referred for attention deficit hyperactivity disorder (ADHD) assessment and 24 non-clinical control children (all children ages 5-16) were given the Test of Variables of Attention…
