Background: In the last decades, children's understanding of mathematical principles has become an important research topic. Different from the commutativity and inversion principles, only few studies have focused on children's understanding of the addition/subtraction complement principle (if a - b = c, then c + b = a), mainly relying on verbal…

The current study examined social cognitive skills in children with nonverbal learning disabilities (NLD) compared to normally achieving (NA) children. The relation between social cognitive skills and psychosocial adjustment was also investigated. There were no group differences on children's ability to represent orally presented social vignettes.…

Analogical reasoning--perceiving similarities in different situations and the transfer of such information--facilitates learning and understanding. However, children with learning disabilities (LD) typically demonstrate deficits in such information processing strategies. In this study, we investigated the analogical problem-solving differences…

Investigated the ontogenesis of oddity learning. Children and adults were tested on two versions of the oddity task using nonverbal procedures. Results suggested that children use different strategies to solve different versions of the oddity task, and in tasks in which stimuli are presented simultaneously, behavior may be controlled by stimulus…

Comparison of cognitive performance of 51 students with hearing loss and 64 hearing students indicated that, at age 10, students with hearing loss performed better on nonverbal tasks and worse on verbal tasks. At age 13, students with hearing loss performed poorly in both verbal and nonverbal tasks. (Author/SW)

The follow-up study of 16 nonretarded autistic children as adults found that, though most were functioning poorly in terms of occupational-social outcome and psychiatric symptoms, four had essentially recovered. Severity of early autistic behavior was a poor predictor of outcome, but neuropsychologic measures of nonverbal problem solving were…

This study investigated conditions for optimizing college students' analogical problem solving. Students given pictorial (not verbal) representations of solutions to source problems were better problem solvers, as were students given a longer time. Students who derived personal solution principles to source problems were not superior to students…

Ten language impaired and 10 language normal children, aged 3-5), were asked to solve verbal and nonverbal problems requiring color and size judgments. There were no group differences on the verbal tasks, but the language impaired children performed less well on the nonverbal tasks especially on problems dealing with size. (Author/DB)

Reports three experiments with kindergartners and first graders which used one-trial multidimensional reasoning tasks like those of Toppino (Journal of Experimental Child Psychology, v30, p496-512, 1980). Feedback information and preliminary experience with simple forms of the task produced high performance levels, and verbal labeling in the…

This article provides an overview of the nonverbal learning disabilities (NLD) syndrome and describes appropriate educational strategies. Primary characteristics of NLD and possible indicators are listed. Remedial, compensatory, instructional or therapeutic interventions are listed for psychomotor and perceptual motor deficits, for arithmetic…

Discusses research on cognitive styles and strategies. Groups labels into two principle styles. Describes the wholist-analytic style, examining whether an individual tends to process information in wholes or parts, and the verbalizer-imager style considering whether an individual is inclined to represent information during thinking verbally or in…

Summarizes experiments indicating that a basic key to learning is the development of concepts of pattern recognition and the appropriateness of using a particular theorem. (Author/SK)
