Three groups of children with communication disorders were assessed using the CELF (Clinical Evaluation of Language Fundamentals). The results were used to compare the language skills of children with specific language impairment (SLI), autistic spectrum disorder (ASD) and a middle group who shared some characteristics of both SLI and ASD (Shared…

This study reports the results of a long-term follow-up of an exercise-based approach to dyslexia-related disorders (Reynolds, Nicolson, & Hambly, "Dyslexia," 2003; 9(1): 48-71). In the initial study, children at risk of dyslexia were identified in 3 years of a junior school. One half then undertook a 6 month, home-based exercise…

After reviewsing the literature relative to culture and cognition, an hypothetical model was developed to explain some aspects of concept learning and cognitive development. To test aspects of the model, 3 tests which had had prior use in cross-cultural studies and 5 original tests were administered individually to 34 Stoney Indian and 34…

The study investigates the effects of linguistic medium (English vs. Chinese), mode of stimulus presentation (visual vs. auditory), and noun frequency on short-term serial recall and serial learning. The results indicate that auditory input facilitates learning for American subjects but not for Taiwanese subjects, who learned somewhat faster with…

Certain aspects of the performance of adults on verbal reasoning tasks were studied. The four main objectives of the study were: to develop a self-instructional booklet for use in teaching adults the functional rules of classification; to construct a reliable instrument for use in assessing the capability of adults to perform verbal classification…

Results of a comparison of 73 Anglo American and 155 Chinese American (CA) fourth through sixth graders on an intelligence test and measures of the speed and consistency of retrieval of arithmetic facts from long-term memory are consistent with the hypothesis that accessing elementary arithmetic knowledge is more completely automatized in CA…

A number of studies have revealed short-term memory deficits in individuals with PTSD. The current study sought to extend these findings to a college PTSD population. Additionally, a cueing manipulation was used to examine the effects of trauma-memory cueing on memory in PTSD and control groups. The study utilized a 2 x 2 (PTSD, No PTSD;…

Children and adolescents with Down syndrome show an emerging profile of speech and language characteristics that is typical of the syndrome (Chapman & Hesketh, 2000; Chapman, 2003; Abbeduto & Chapman, 2005) and different from typically developing children matched for nonverbal mental age, including expressive language deficits relative to…

A total of 102 children (17 from each of the kindergarten, first, and second grades and of two disparate socioeconomic backgrounds) were administered a series of tasks involving verbal recall. The purpose of this testing was to compare the verbal recall ability of children of different ages and socioeconomic status. The verbal material was read to…

It may be possible, using assessments of motor and perceptual skills which are largely independent of ethnic and educational background, to admit to the military individuals who would be rejected on the basis of their paper-and-pencil test scores, but who through their performance on non-verbal measures, can be identified as highly likely to…

The present study was undertaken to assess whether training that was known to produce transfer within the Cognition of Figural Relations (CFR) domain of Guilford's Structure-of-Intellect model would also produce transfer to other operations in Guilford's model. Fifty subjects, matched for pretest score on a double classification task, were…

The present study investigated the relation between executive functioning and symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) in children aged 4-6. A population-based sample (n = 201) was used and laboratory measures of inhibition, working memory and verbal fluency and teacher ratings of…

Background: Deficits in executive functioning are supposed to have a predisposing influence on impulsive or aggressive behaviour. We tested the hypothesis that oppositional-defiant disorder (ODD) children with or without attention deficit hyperactivity disorder (ADHD) have problems in executive functioning. Method: Seventy-seven 7- to 12-year-old…

The main hypotheses addressed in the research were (1) whether imprecision in the phonological representations of lexical items underlies the impaired expressive naming abilities of disabled readers, and (2) whether weak verbal memory might mediate the relationship between naming and reading skills. From samples of 93 first graders and 67 fourth…

Compares the cognitive development of four subcultural groups of boys (Black and White, and lower- and middle-class) in order to test Arthur Jensen's theory. Nine-hundred subjects were studied for four years, and memory, intelligence, learning and transfer measures were employed. (Author/RH)
