A study of 93 Spanish-speaking Latin American children of low socioeconomic background with reading difficulties found that, 4 years later, 17% had average reading ability, but 11% remained with severe reading difficulties. Characteristics examined include IQ, phonological processing, decoding ability, reading comprehension, and other verbal…

Seven techniques for measuring information processing in infants are proposed to aid in the early identification of mental retardation. The techniques are based on conditioning, attentional, and manual exploration paradigms and could be combined into an assessment battery more valid than current infant IQ tests in predicting later disability.…

An empirical analysis of the relationship between science reasoning skills and the amount of information acquired during science learning as predicted by a neuromathematical model of information processing is presented. Subjects were 93 adolescents (mean age of 15.4 years old) with a IQ range of 91-142. (Author/JN)

For 139 students, algebra prognosis test scores and performance in seventh-grade mathematics best predicted algebra grades in grade eight, whereas IQ, problem solving, and prognosis scores best predicted achievement on a standardized algebra test. No sex difference in achievement scores was found, but girls attained higher percentage grades. (MNS)

Based on data gathered during their public elementary school education, two groups of 49 students in private and public schools were matched on age, ethnicity, gender, socioeconomic status and IQ. Their achievement test scores as high school seniors do not support the claim that private schools necessarily effect higher achievement. (BS)

Seventeen patients with Asperger syndrome (AS) and a mean IQ of 97 were compared with a control group of 13 patients with normal intelligence or high-functioning autism. Results found that pedantic speech was common in the patients with AS and may help differentiate AS from high-functioning autism. (Author/CR)

Examines response styles to cognitive demands of the WISC exhibited by 7- to 10-year-old black children adopted by either white or black middle-class families. A significant difference in the average performance of the two groups of children was observed, favoring those adopted by white families. Mothers' helping behaviors differed by race.…

A 2-year study of 25 learning-disabled children (ages 8-14) found that intelligence quotient had no relationship to learning ability in a remedial program. Self-concept predicted patterns of successful achievement in spelling, arithmetic, and written language but not in visual word recognition. (Author/JDD)

The increase in the number of Canadian students whose home language is different from the school language has serious implications in the areas of minority student assessment, possible bias of IQ tests, minority student English-language acquisition, and recommendations to parents regarding home language use. Research and educational considerations…

The purpose of this study was to replicate previous factor analytical studies of the Wechsler Intelligence Scale for Children-Revised (WISC-R) employing children identified as gifted. However, rather than using the IQ criterion, a child's 11 WISC-R subtest scores were included in the analysis. Subsamples of gifted (as classified by local school…

Examines the mental development scores for two groups of at-risk infants throughout their childhood--those classified as small for gestational age (SGA) and those twins falling below 1,750g birth weight--and determines that SGA twins showed only a modest deficit in IQ scores as compared to the full twin samples. (HOD)

Many variables mitigate against a culture-fair test being devised. The Queensland Test--which has been administered to Aboriginal children--is probably fairer than most IQ tests, although it appears to measure the degree of contact with Western culture (implying socio-economic variables) rather than mental and chronological age or cognitive…

Among a group of 103 children with a mean age of eight years, full-scale IQ correlation was significantly higher for monozygotic than dizygotic pairs. Monozygotic pairs also showed significantly greater concordance for subtest profile than dizygotic pairs. The usefulness of profile analysis is examined, and directions for future research are…

This study examined the effectiveness of a social skills training program for five male adolescents with autism but normal IQ. In addition to teaching interactional and conversational skills, the program provided explicit instruction in social-cognitive principles of inferring the mental states of others. Significant changes in beliefs were found,…

This overview reviews a program of interlinked cross-sectional and longitudinal investigations of the nature of cognitive development in infants and young children with Down's Syndrome. The research falls into three groupings: object concept studies, operant learning experiments, and IQ studies. Early results suggest a common learning style which…
