Cognitive subtest scatter has often been considered to be diagnostically significant. The current study tested the diagnostic validity of four separate operationalizations of WISC-III subtest scatter: (a) range of verbal, performance, and full-scale subtests; (b) variance of verbal, performance, and full-scale subtests; (c) number of subtests…

This study examined differences in the manifestation of learning disabilities (LD) between minority and non-minority students at a southeastern public college. Profiles of non-minority and minority college students not previously identified as learning disabled and with a history of academic difficulty were compared. Among trends noted in both…

Item bias in the Wechsler Intelligence Scale for Children (Revised) was investigated using black, white, and Hispanic learning disabled children. Samples of 112 blacks, 126 whites, and 117 Hispanics were matched on subtest raw score and sex. An item-by-group analysis of variance was computed on delta transformed item means for each of nine…

This article describes a new testing method which can be used to screen learning-deficient children fast, reliably, and inexpensively out of any population of public school systems. (Editor)

The study examined the role of verbal mediation in language processing by 88 children (ages 8-12 years) with low verbal/high performance Wechsler Intelligence Scale for Children (WISC) profiles. (Author/PHR)

The article, fifth in a series on subtests of the Wechsler Intelligence Scale for Children Revised (WISC R), discusses how to use pattern analysis of the Similarities (verbal) and the Object Assembly (performance) subtests in diagnosis of learning disorders and prescription of instructional approaches. (IM)

Evaluates the utility of the Bannatyne recategorization of WISC-R subtest scores for diagnosing and prescribing instruction for reading/learning disabled children. Concludes that the use of such scores is not warranted. (FL)

Major research findings relevant to use of the Wechsler Digit Span subtest in psychoeducational assessment are summarized. The cognitive processes and behavioral characteristics which determine performance on Digit Span are related to complex abilities. Recommendations and implications for research and assessment practice are presented.…

Past research has suggested memory, writing speed, and paired-associate learning rate to be important in WISC-R (Wechsler Intelligence Scale for Children Revised) coding performance. Suggested that visual perceptual factors also may be important and that coding performance in right-handed persons may be especially sensitive to integrity of the…

Reanalyzed the Wechsler Intelligence Scale for Children-Revised subtest scores in Dean's 1978 study of learning disabled and emotionally disturbed children. Analysis revealed a marked similarity between the groups. Results support Sattler's contention that Dean's data do not present evidence of a perceptual organization deficit in learning…

Wechsler Intelligence Scale for Children, Revised (WISC-R) Verbal, Performance, and Full Scale IQ's were compared with Bannatyne recategorized WISC-R scores for groups of non-handicapped, educationally disadvantaged, learning disabled, and regular classroom Navajo Indian children. No definitive evidence was found to support the use of the…

The discrepancy between middle-class and lower-class children's performance on IQ tests has been thought of as "cognitive deficit" or as "cognitive differences." This paper proposes another explanation--cognitive lag hypothesis--according to which the low IQ test scores of lower-class children are seen as due to the developmentally delayed…

Examines the Symbol, Search, Coding, Arithmetic, and Digit Span (SCAD) subtests of the Wechsler Intelligence Scale for Children (3rd ed.) (WISC-III) by comparing 363 students with learning and emotional disabilities to the WISC-III normative sample. Results indicate that the SCAD profile is neither a valid diagnostic indicator nor an important…

The Learning Disability Index (LDI) was validated by an examination for mean profiles and demographic characteristics of high and low LDI subsets of the standardization sample of the Wechsler Intelligence Scale for Children-Revised. The LDI continuum was found to measure Third Factor strengths/weaknesses as much as verbal-performance…
