The current prospective cohort study investigated whether early perceptual abilities, measured at preschool age, could predict later intellectual abilities at school age in a group of 41 autistic (9 girls, 32 boys) and 57 neurotypical children (29 girls, 28 boys). More than 80% of the autistic children were considered minimally verbal.…

This study considered a relation between rhythm perception skills and individual differences in phonological awareness and grammar abilities, which are two language skills crucial for academic achievement. Twenty-five typically developing 6-year-old children were given standardized assessments of rhythm perception, phonological awareness,…

Reading with comprehension is a challenge for students with high-functioning autism spectrum disorder. Unfortunately, research has little to offer to teachers trying to help these students. The present study pilots a new intervention targeting vocabulary, main idea identification, anaphoric relations, and text structure. Students (N = 13, M…

Background: Previous research with earlier versions of the WISC and WAIS has demonstrated that when administered to people who have intellectual disabilities, the WAIS produced higher IQ scores than the WISC. The aim of this study was to examine whether these differences still exist. A comparison of the Wechsler Adult Intelligence Scale-Third…

In this study, long-term intellectual functioning and school-related behavioural outcomes were assessed in a patient sample that underwent invasive treatment for congenital heart disease (ConHD) between 1990 and 1995. The Wechsler Intelligence Scale for Children-Revised was used to measure intellectual functioning and the Teacher's Report Form to…

Reports a study conducted to assess the knowledge, attitudes and opinions of preschool children concerning a public figure through use of a questionnaire administered orally. (ED)

Regression analysis revealed that a reliable estimate of the field-analytic disposition could be derived from a composition of scores on the Gottscaldt, Space Relations, Street Gestalt, and Perceptual Acuity tests. (Author)

A verbal comprehension deviation quotient and a perceptual organization deviation quotient are presented as alternatives to the Verbal and Performance IQs when attempting to measure the Wechsler Intelligence Scale for Children-Revised verbal comprehension and perceptual organization factors. The freedom from distractibility deviation quotient…

The EEG biofeedback training produced baseline effects in the presumably dysfunctional left hemisphere and had an impact on arousal in task, suggesting remedial potential for the possible hemispheric arousal deficts in learning disabilities. Training the right hemisphere toward higher arousal and the left hemisphere toward lower arousal resulted…

Comparison of the mental status of 30 subjects with Down's Syndrome mosaicism and 30 matched subjects with trisomy 21 Down's Syndrome found that the mean intelligent quotient of the mosaic Down's Syndrome group was significantly higher and that this group showed better verbal abilities and more normal visual-perceptual skills. (Author/DB)

The two groups were not significantly different on tests of lipreading and reception of signed English, but the hearing Ss were superior on tests of nonverbal reasoning and perceptual speed. Hearing Ss were greatly superior on a test of verbal reasoning. (Author/DLS)
