Use of an abbreviated version of the WISC-R with learning disabled children

The Wechsler Intelligence Scale for Children-Revised (WISC-R) was administered to 56 learning disabled children, using standard assessment procedures and format as outlined by Wechsler. Abbreviated IQ scores were then derived by applying the Kennedy-Elder formula, and equation that uses five WISC-R subtests with varied weightings. Comparisons between the standard IQ scores and the abbreviated IQ scores were evaluated. A Pearson product-moment correlation coefficient of .83 and a non-significant t-test between the mean IQs suggested the two scores were interchangeable. However, frequent IQ classification changes (23%) rendered the K-E format unacceptable for this population.     

The social perception of learning disabled and non‐learning disabled children

This study was undertaken to determine if there were differences in the social perception of learning disabled and non‐learning disabled youngsters, whether social perception was related to sex and if interaction by sex and learning disability status was involved. Fifty‐seven elementary school children aged 9 to 11 years were given four measures of social perception. Results showed that learning disabled children differed significantly (p .01) from their non‐learning disabled peers on each of the four measures. Neither sex nor group by sex interaction was significant. Assessment and intervention aimed at improving social perceptual skills should be incorporated into educational programming for those learning disabled children who exhibit deficiencies in this area of functioning.     

Use of the WISC-R and K-ABC with learning disabled,borderline mentally retarded,and normal children

The aim of this investigation was to examine normal (N = 34), learning disabled (N = 34), and borderline mentally retarded (N = 33) children's performance on the WISC-R and K-ABC. Results revealed no significant differences between the WISC-R Full Scale IQ and K-ABC Mental Processing Composite by group (F = 0.7, p > .15). The Full Scale IQ and Mental Processing Composite standard score correlated .85 for the entire sample, and all other subscale correlations ranged from .65 to .90 (all significant at p < .001). Analysis of Verbal-Performance, Mental Processing-Achievement, and Simultaneous-Sequential discrepancy means by group revealed no significant differences in comparison to normative values. Subtest patterns analysis revealed high rank order correlations between the learning disabled and mentally retarded groups, but lower correlations between the exceptional and normal groups. Implications of these findings are discussed.     

Use of the WISC-R with a learning disabled population: Some diagnostic implications

A group of 41 learning disabled children in Hawaii, aged 6 to 151/2, were tested on the WISC-R. Two main questions were explored: (a) Do the separate WISC-R tests assess “g” for learning disabled children to the same degree that they do for normal children? (b) Is there significantly more scatter among the tests for learning disabled than for normal youngsters? The answers to these questions were interpreted in terms of their diagnostic significance.     

Written narratives of normal and learning disabled children

Writing samples of children in grades one through three were collected in two midwestern elementary schools using the Picture Story Language Test. Each story was scored for productivity, syntax, and level of abstraction. Results indicated that performance in all aspects of written language improved with age. A second study was conducted to compare the writing of normal children who were average readers in grades one through three with learning disabled children who were reading at comparable levels. The results indicated no significant differences in productivity but there were differences in syntax. Problems were noted particularly in morphology. Further observations indicated the learning disabled poor readers also had more problems with handwriting and spelling than average readers.     

Social inference skills in learning disabled and nondisabled children

The study examined the performance of 30 learning disabled and 30 nondisabled children in grades 1 through 7 on the Test of Social Inference (TSI). Results indicated that disabled students obtained lower TSI total scores that did nondisabled students: they also performed relatively lower on TSI items requiring more verbal expression. While no difference was found between the groups on the Motor-Free Visual Perception Test (MVPT), the relationship between MVPT and TSI scores was shown to be significant within the disabled group only. Furthermore, this group made more perceptual-type errors on the TSI. Findings are discussed in relation to previous research suggesting a link between visual perception and/or language fluency and social inference skills among learning disabled children.
