Ss were presented with the task of naming lower case letters "b,""d,""p," and "q" in 30-second and untimed trials, respectively. The results, in general, showed that reversal errors decreased abruptly when incentives were introduced and, in some instances, did not increase when incentives were removed. (Author/DLS)

Available from: Journal of Pediatric Psychology, Child Study Center, 1100 N.E. 13th Street, Oklahoma City, Oklahoma 73117. The author reviews some research in the area of the neuropsychology of learning disabilities (LD) with emphasis on the qualitative analysis of spelling errors in disabled spellers and the predictive accuracy of various…

Integrated treatment methods of neuropsychological and cognitive origin were evaluated with 80 Dutch children (ages 6-15) with severe dyslexia. Treatment with flash cards, which exercised automatic letter-sound conversions, had a robust and slight effect in preclinical and clinical phases respectively, whereas hemisphere stimulation produced…

Investigates the changes of neuronal response according to a four time repetition of audio-visual learning. Obtains EEG data from the prefrontal (Fp1, Fp2) lobe from 20 subjects at the 8th grade level. Concludes that the habituation of neuronal response shows up in repetitive audio-visual learning and brain hemisphericity can be changed by…

Examines the role of the brain in conceptualizing and understanding intrapersonal communication. Drawing on research and theory from several disciplines, develops a communicative perspective on intrapersonal communication, focusing on specific interhemispheric and intermodular processes inherent in intrapersonal communication. Discusses…

Analysis of 51 studies of developmental effects of prenatal exposure to alcohol in children from birth to 72 months found that, although adverse outcomes were found within each domain, age grouping, and exposure category, they comprised fewer than 50% of all outcomes measured. Most adverse outcomes were found in the neurobehavioral domain with…

This study reports clinical characteristics of developmental right-hemisphere syndrome, a nonverbal learning disability, in 20 children (mean age 9.5 years) who also manifested attention-deficit/hyperactivity disorder, graphomotor problems, and slow performance. Diagnostic criteria included emotional and interpersonal difficulties, paralinguistic…

Examines the potential contribution of different neural systems to developmental change in the duration of visual fixation, and the individual differences in that variable that are predictive of subsequent cognitive function. Presents hypotheses concerning two specific and independent neural systems and how they might contribute to individual and…

The area of adult learning disabilities is reviewed from a neurobiological and neuropsychological perspective. The paper covers possible pathophysiologic bases in dyslexia, neurobehavioral disorders that may coexist with learning disorders, neuropsychological assessment methods, treatment in the context of brain plasticity and recovery of…

Describes the interdisciplinary research of Myrtle B. McGraw; examines the controversy about McGraw's concept of critical period; and assesses her impact on current research. McGraw contended that the overlapping phases involved in neuromuscular integration demonstrate that learning and maturation interact during development. (BC)

This article introduces two conference papers (EC 607 450 and 451) which discuss the link between basic research into brain structure and function and the applied issues of instructional intervention in dyslexia. The papers, based on longitudinal studies at the Bowman Gray School of Medicine (North Carolina), were presented at a Middle Tennessee…

Examines WAIS-R profiles of 194 college students diagnosed with learning disabilities (LD) to assess where they yield unique and interpretable profiles. Results show nearly 94% match profiles found in the WASI-R standardization sample. Also, shapes fail to explain a significant proportion of variation in student academic skills. (Author/JDM)

Nineteen individuals with autism either listened to auditory integration training processed music or unprocessed music for 20 half-hour sessions. A significant decrease in Aberrant Behavior Checklist Scores was observed in the experimental group at the 30-month follow-up assessment. In addition, three experimental subjects but no controls showed a…

A study investigated electroencephalographic (EEG) differences between children with attention-deficit/hyperactivity disorder with reading disabilities (ADHD + RD) (n=20) or without (n=20), and 20 controls. Results indicate differences found in the ADHD + RD group represent an electrophysiological component associated with the reading disability…

This review presents the most recent research concerning neuroimaging in developmental disabilities. Changes in structure and activation have been found in children with ADHD and learning disabilities, following intervention. For the children with learning disabilities changes in activation have been found following intensive behavioral and…
