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.     

The development of working memory in normally achieving and subtypes of learning disabled children

Working memory has been proposed as an important component of reading and arithmetic skills. The development of working memory was studied in normally achieving and subtypes of learning disabled children. The performance of reading disabled (RD), arithmetic disabled (ARITHD), and attentional deficit disordered (ADD) children, age 7-13, was compared to normal achievers (NA) on 2 working memory tasks, 1 involving sentences and the other involving counting. There was a significant growth of working memory as a function of age. In addition, the RD children had significantly lower scores on both tasks. The ARITHD children had significantly lower scores only on the Working Memory--Counting task, and the ADD group had scores similar to the normally achieving children except at the youngest age level in the Working Memory--Sentences task. Thus, a reading disability appears to involve a generalized deficit in working memory. Children with an arithmetic disability do not have a generalized language deficit but have a specific working memory deficit in relation to processing numerical information. As children with ADD did not have deficits in these tasks, working memory may not have significant attentional components. An important component of the development of reading and computational arithmetic skills appears to be the growth of working memory for language and numerical information.     

Analysis of cognitive abilities for learning disabled children

The study investigated WISC-R subtest pattern scores of 58 learning disabled children (42 boys and 16 girls) ranging in age from 6 years to 15 years, 10 months. The variation in subtest scores was analyzed by a 1 X 10 analysis of variance with repeated measures on the single factor. Differences between individual subtest means were analyzed by the Newman-Keuls test for simple effects. The evidence indicates that the low subtest scores on Arithmetic, Coding and Information were characteristic of this group. The study did not support the verbal-Performance discrepancies as useful in the diagnosis of learning disabilities.     

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.
