The study of cognitive processing in high IQ and average IQ elementary grade learning disabled and non-learning disabled children found that LD students were poorer in sequential processing and planning compared to NLD students; high IQ LD students lost their IQ advantage to low IQ LDs in sequential scores.

Explores the generality of findings relating intelligence to Inspection Time (IT), the exposure necessary to judge which of two lines is longer, in two studies using normal children and mentally retarded adults. Results showed the relationship between IT and performance IQ was lower in the mentally retarded group. (JAC)

A study of 62 children (ages 7 to 12) with attention-deficit hyperactivity disorder (ADHD) and 62 controls found that behavioral variables established robust, statistically significant differences between groups. Children with ADHD also scored worse on 31 out of 61 neuropsychological variables, but obtained better scores on WISC-R Comprehension…

Forty children (ages 7-11) referred for evaluation of learning problems, who had normal scores on measures of academic achievement, were compared to 81 similarly referred children who had scored low. Children with normal achievement scores had higher IQs and better decoding skills, however, the two groups showed similar neuropsychological…

Two experiments examined whether correlations between IQ and probed serial running memory depend on IQ-related individual differences in the retention of order information in short-term memory. Children's IQ correlated with memory, regardless of whether instructions emphasized serial or free recall; and with recent item but not recent order…

This study examines some relationships pertaining to socioeconomic status and cognitive ability patterns in fourth graders. Specifically, it explores the relative merits of Jensen's hierarchical theory of two levels of cognitive ability, in contrast to a process scheme, positing two parallel modes of coding information.

Elementary children (n=112) comprising average IQ, high IQ, dyslexic, and normal readers were administered measures of planning, attention-arousal, simultaneous and successive processing, phonemic segmentation, and nonverbal IQ. Cognitive tasks differentiating dyslexic from normal readers were the successive processing tasks and two tasks of…

Longitudinal data on the auditory forward and backward digit span (FDS and BDS) subtests of the Wechsler Intelligence Scale for Children (WISC) were obtained at five age levels (between 6 and 13), in samples of white and black children. Factor analysis and analysis of variance of the data were conducted to test 5 hypotheses, related to Jensen's…

Major visuospatial and verbal abilities were assessed for 197 10-year-olds in Hong Kong and 170 10-year-olds in the United Kingdom. The Hong Kong subjects resembled their Japanese counterparts in having high Searman's "g," exhibiting abstract reasoning ability, high spatial ability, high perceptual speed, and low word fluency.

An experimental group of 51 students from non-graded and three matched groups of 187 pupils from graded programs were studied to determine the relative effectiveness of non-graded and graded approaches to elementary education and whether any differences found at the end of six years of schooling remained after both groups had been exposed to a…
