This small-scale pilot research project investigates the prevalence of Speech Language and Communication Difficulties in a sample of children attending a Youth Offending Service in the UK. Using the CELF-4, approximately 90% of the sample displayed some form of language difficulty and, overall, this population displayed mild to moderate…

Canonical analysis is used in this study to identify the number and nature of orthogonal components shared by the WISC and the ITPA and to assess the degree to which the subtests of the two instruments are redundant. (Author)

In this study only bias in scoring, controlling for the effect of actual administration, was investigated. Results indicated that scoring the WISC was biased by scorers' expectations, and that the bias effect exists independent of actual administration of the test. (Author)

So as to compare the results of the WISC and WISC-R, instruments were administered to 58 children. All IQs were significantly higher on the WISC, with the Performance difference being greater than the verbal difference. Regression equations were obtained to predict WISC-R IQs from WISC scores.

An experimental study was undertaken with 120 educable mentally retarded students to examine the effect on performance of three types of test item response reinforcers (token, verbal praise, verbal neutral), and two levels of reinforcement schedule (fixed and continuous ratio). (Author)

Investigates the relationship between the WISC IQ and academic achievement in regularily placed first-grade black children. (Author)

Mentally retarded youngsters (N=80) aged 6 to 16, were tested on the WISC-R, primarily to assess the continuity of measurement between the old and new WISCs. There was evidence to support the continuity of the WISC-R with its predecessor for retarded populations. (Author)

Judges (N=10) scored items from the Comprehension, Similarities, and Vocabulary subtests of the WISC-R. Five were inexperienced undergraduates and five were experienced Phds. Overall, there were no appreciable differences in the percentages of agreement between the two groups. (Author)

WISC and WISC-R test results were correlated with achievement test scores and school grades of 36 children who had completed two years of school. Global intelligence estimates from both scales correlated at significant levels with all achievement test measures. (Author)

Interrater differences in scoring actual WISC protocols were determined for three different IQ levels. In general, differences among the 94 examiners tended to be within an acceptable range as established by the standard error of measurement; variance on two Verbal subtests occasionally exceeded their corresponding standard error of measurement.…

WISC performance of Jewish children has revealed a highly consistent and stable pattern, characterized by relatively low scores on Picture Completion, Picture Arrangement, Block Design, and Object Assembly. Some of these findings might be understood by reference to relative weakness of Jewish subjects on tasks related to psychological…

Fabricated test protocols were used to study how effectively examiners agree in scoring ambiguous WISC-R responses. The results suggest that, even with the improved WISC-R manual, scoring remains a difficult and challenging task. (Author)

The study compared differences and similarities between WISC and WISC-R scores for 48 ten- and thirteen-year-old educable mentally retarded students, who were matched according to sex and race. Results suggest that many children classified as "Borderline" or slightly above the WISC will be classified as "Mentally Deficient" by…

Children were tested on the WPPSI and Stanford-Binet and after three years they were tested on the WISC. Results indicate that the WISC scores were significantly higher than the two other tests. The results of the various subtests of the three tests are compared and discussed. (SE)
