These authors cite their own study of the relationship between traditional measures of intelligence and Piagetian measures of cognitive development in support of Glass and Stephens' contention that there are important qualitative differences. They question Humphreys' and Parsons' conclusions on both substantive and factor theoretical grounds. (CTM)

Background: The study was conducted in an attempt to further our understanding of how working memory contributes to written arithmetical skills in children. Aim: The aim was to pinpoint the contribution of different central executive functions and to examine the contribution of the two subcomponents of children's written arithmetical skills.…

This review critically examines the research findings which characterize the cognitive, behavioral, and neuroanatomical features of Williams syndrome (WS). This article analyzes 178 published studies in the WS literature covering the following areas: 1) General intelligence, 2) Language skills, 3) Visuospatial and face processing skills, 4)…

There is a debate about whether the language of children with primary language disorders and normal cognitive levels is qualitatively different from those with language impairments who have low or borderline non-verbal IQ (NVIQ). As children reach adolescence, this distinction may be even harder to ascertain, especially in naturalistic settings.…

Young adults, originally tested as infants for their ability to process information as measured by selective attention to novelty (an operational definition of visual recognition memory), were revisited. A current estimate of IQ was obtained as well as a measure of academic achievement. Information processing ability at 6-12 months was predictive…

It is often the case that intelligence tests do not measure what they purport to measure, although it is commonly assumed that every test with a different name is a test of different skills, and that tests with the same name test the same skills. Spearman attempted to study the relationship between tests that supposedly measured different mental…

Two introductory passages, one regular passage, and one experimental advance organizer passage developed to facilitate initial learning were assigned to normal and retarded children. The subjects were 184 normal 8-year-olds (controls' mean IQ 118.00, organizers' 118.80) and 184 educable mentally retarded 15-year-olds (EMR controls' mean IQ 74.85,…

The purpose of this study was to (1) find if spelling approaches could be isolated and classified by the use of the JDR Spelling Checklist (an interview-type questionnaire); (2) determine the incidence of approach--visual, auditory, kinesthetic, or combination--used by students in spelling new words; (3) see if a relationship existed between the…

Students of high intellectual ability and their parents were tested on a battery of cognitive tests. Vernon's model of intelligence best fit results. A verbal-educational and a practical-spatial-mechanical factor explained most performance variance. Among children, age related to verbal but not spatial or mechanical abilities. (Author/RD)

The Processing Speed Index (PSI) was first introduced on the Wechsler Intelligence Scale, Third Edition (WISC-III; D. Wechsler, 1991), and little is known about its clinical significance. In a referred sample (N = 980), children with neurological disorders (ADHD, autism, bipolar disorder, and LD) had mean PSI and Freedom from Distractibility Index…

In order for information to be stored and processed in a computer, it must be reduced to data and organized and systematized in accordance with the rules and principles of formal logic. Reducing manifold reality to data for use by the computer results in loss of information because an arbitrary screening of data eliminates that gathered by the…

The development of concept usage was studied in 120 normal, mildly retarded, and moderately retarded children. A forced-choice match-to-standard task was used, with the equivalence matches compared with the Ss' explanations of their choices. Among the findings were that performance was related to the stimulus condition (competing versus…

The past 20 years have seen a resurgence of interest on the part of psychologists in what used to be called "the higher mental processes," with the difference that while the earlier workers were concerned with the power of reasoning, recent interest has centered upon the use of language. The scope of the material that has appeared is frequently…

Analysis of Wechsler Intelligence Scale for Children-Revised protocols for identified gifted, high IQ, and average children (total N=599 and ages 5-16) identified a four-factor solution for the gifted sample (Perceptual Organization, Verbal Comprehension, Acquisition of Knowledge, and Spatial Memory). Results suggested gifted children process…
