This study examined the factor structure of the Detroit Tests of Learning Abilities, Fifth Edition (DTLA-5) using principal axis factoring, multiple factor extraction criteria, and the Schmid-Leiman orthogonalization procedures not utilized by test publishers. Results suggest that the publisher's six-factor structure model was over factored.…

Bayesian structural equation modeling (BSEM) was used to investigate the latent structure of the Differential Ability Scales-Second Edition core battery using the standardization sample normative data for ages 7-17. Results revealed plausibility of a three-factor model, consistent with publisher theory, expressed as either a higher-order (HO) or a…

Evaluated correlations between Wechsler Intelligence Scale for Children-Revised, Woodcock-Johnson (W-J) Achievement clusters, Woodcock-Johnson Aptitude clusters, and Broad Cognitive Ability Score in 60 Behavior-Disordered male adolescents. Aptitude cluster scores had insufficient validity to justify computation for population; Broad Cognitive…

The revised ITPA promises to have continued wide application. It successfully measures general linguistic ability and intelligence, and to a limited extent it successfully measures aspects of cognitive ability. However, it fails to measure many of the cognitive domains that it was designed to measure. (Author)

Tested the factor structure of the McCarthy Scales of Children's Abilities in preschool children (N=141). Found existence of Verbal factor and other Perceptual-Performance factor was confirmed and the Quantitative and Memory factors appear undifferentiated. Found subtests which make up the Motor scale do not constitute a single factor. (Author/ABL)

Administered McCarthy Scales of Children's Abilities to preschool children of normal intelligence with (n=25) and without (n=25) speech/language disorders. Speech/language disorders group had significantly lower scores on all scales except Motor; showed difficulty in short-term auditory memory skills but not in visual memory skills; and had…

Compared intrachild variability of five-year-old children on the Primary Mental Abilities Test when subjects reached their fifth birthday after completing at least two years of preschool enrichment. Conclusions, although qualified on the basis of limited sample size, revealed wider intrachild variability with minority children. (Author)

The results of this study suggest that instructions are a source of information to students about the testing environment that modifies their test-taking behavior. Individual students interpret the same instructions in different ways, and these differences, in turn, result in variations in behavior reflected in test scores. (Author)

This study evaluates the reliability of profile analysis for assessing differential abilities on the McCarthy Scales for Children's Abilities (MSCA). Subjects were enrolled in private schools. Results indicated 70.9 percent of the sample showed profile variability not reasonably accounted for as real fluctuations in measurable abilities. (Author)

The data of the present study supplement those given by Vane and also provide a context in which to assess the differential abilities of Negro and Puerto Rican Head Start Children on verbal and performance tasks. (Author)

This study investigated sex differences on the Wechsler Intelligence Scale for Children-Revised (WISC-R) subtests for retarded males and females who were matched in terms of WISC-R Full Scale IQ's. Sample consisted of 126 children. Evidence from the investigation indicated that a significant interaction effect existed between sex and subtest…

Investigated the effect of examiners' ethnicity on the intelligence test performance of Anglo and Mexican-American subjects. On the WISC Vocabulary, Mexican-American subjects scored significantly higher when the test was administered by Mexican-American examiners. (Author)

The Beery-Butkenica Developmental Test and the Caldwell Test were the best predictors. Combining the academic performance with visual-motor integration results at age seven years yielded 89 percent accuracy of prediction at age nine years. The false-positive rate represents the problem of mislabeling children as school failures. (Author)
