Aim: Although approximately 40% of children with neurofibromatosis type 1 (NF1) meet diagnostic criteria for attention-deficit-hyperactivity disorder (ADHD), the impact of ADHD on the executive functioning of children with NF1 is not understood. We investigated whether spatial working memory and response inhibition are impaired in children with…

Results showed that under research conditions, gifted students in the experimental population did significantly better than average students in the experimental and control groups. (Author/SBH)

Analyzed is the Piagetian concept of cognitive structure (concerning an individual's thought organization) and noted is the lack of precise psychological definition. Reviewed are deficiencies in Piaget's theories relating to developmental stages of the cognitive structure. Elements of the cognitive structure are defined; five basic assumptions are…

The profiles of 40 educable mentally retarded (EMR) children (aged 6 to 8.5 years) on the McCarthy Scales of Children's Abilities were examined to determine areas of strengths and weaknesses. (Author)

Data from a Class Activities Questionnaire was used in the evaluation of the state gifted program in Illinois to determine patterns of cognitive and affective emphasis in gifted and average classes. Significant differences were found in the degree of emphasis on higher thought processes, classroom focus, and classroom climate. Significant…

Findings indicated that (1) stable preference measures could be obtained, (2) high preference objects resulted in higher motivation to perform and hence higher levels on each scale, (3) performance of this population is not stable, and (4) ordinality was violated in nearly 20 percent of the administrations of the scales.

The paper traces the development of an integrated model of cognition stemming from Soviet neuropsychology and reviews recent research on simultaneous and successive syntheses. Implications for mental retardation, learning disability, hyperactivity, and reading disability are given. (Author/CL)

Creative thinking and problem solving processes were studied in 233 gifted elementary students. (Author/DLS)

Three studies were conducted with three groups of eighteen autistic children (3-11 years old) matched by age and IQ to developmental aphasic Ss to examine the nature of the cognitive deficit underlying autism. Two experiments were concerned with language comprehension using real and anomalous sentences, while the third investigation was an…

Two studies using the concepts and research techniques of J. Piaget were conducted to compare cognitive processes in 45 blind children (2-to-12-years-old) and a random sample of sighted children. (SB)

Intended for graduate students in special education, the text presents seven author contributed papers dealing with theoretical issues in the field. M. Faust and W. Faust ("Cognitive Constructing: Levels of Processing and Developmental Change") consider cognitive processing from a developmental perspective. In "Memory Processes in Exceptional…
