Determined if intelligence quotient mean test scores of middle school students could be increased through the use of money and praise. Results indicated lower class performance increased with monetary reward, whites' performance increased with verbal praise, and white females' and middle class males' performance increased with monetary reward…

Data on the magnitude of significant Wechsler Intelligence Scale for Children-Revised Verbal-Performance Intelligence Quotient (IQ) discrepancies (specifically the nondirectional aspect of significant frequencies) within the normal population are often misunderstood by clinicians. Suggestions for remedying inaccuracies in reporting discrepancies…

The Ramey and Haskins intervention experiment is examined. Narrow transfer of training from cognitive intervention techniques to IQ test performance in early childhood, rather than enhancement of the g factor itself, is hypothesized as a cause of the typical fadeout of early IQ gains in later childhood. (Author/RD)

Measurements derived from reaction time, movement time, and an index of neural adaptability derived from averaged evoked potentials are significantly related to each other as well as to g factor scores extracted from a battery of 15 psychometric tests in a sample of 54 severely retarded adults. (Author/RD)

Findings showed an almost even percentage of boys and girls, that more girls had fathers with doctorate degrees, that girls' arithmetic and spatial abilities were not significantly different from boys', that girls increased or decreased in IQ more than boys in high school, and that boys' IQs and grade point averages were significantly correlated…

In this commentary on Linda Siegel's paper (EC221505), it is argued that a minimum level of general ability is needed for successful reading performance. Above this threshold other kinds of intelligence are required and more important is the contribution of verbal efficiency, which is predicated on the covariance of phonology, morphology, and…

The construct validity of a supplemental scoring system for the Kaufman Assessment Battery for Children (K-ABC) was evaluated with 146 referred school-age children (aged 6 to 12.5 years) and the K-ABC normative sample. Results support the construct validity of only part of the scoring model. (SLD)

Responds to "The Bell Curve" by arguing that IQ is merely a statistical fiction, an artificial construct not corresponding to any real entity. Discusses the "seductive statistical trap of factor analysis" as it relates to IQ tests, multiple intelligences, content and bias of IQ tests, lack of validity of IQ tests for individual…

This article, which introduces six papers on the validity of distinguishing subgroups of children with language and learning disabilities based on discrepancies between academic attainment and intelligence test scores, comments on the papers' diversity in samples, measurement characteristics, and statistical approaches and outlines the studies'…

Study sought to determine whether separate short-term auditory and visual memory factors would emerge given a sufficient number of markers in a factor matrix. A principal component factor analysis with varimax rotation was performed. Short-term visual and short-term auditory memory factors emerged as expected. (RJM)

Whether external validity of intelligence quotient (IQ) scores from the Wechsler Intelligence Scale for Children--Revised is moderated by reading ability was studied with 382 Canadian elementary school students. Little evidence was found that IQ scores had less concurrent validity for poor readers. Implications for remedial services provision are…

Introduces the inspection-time (IT) measure in psychology, and argues that its much-replicated correlation with intelligence quotient (IQ) and its potential for theoretical tractability has more potential for the understanding of individual differences in cognitive ability than other indices of human information processing. It summarizes studies…

The authors present a diagnostic profile of Gerstmann's syndrome, the subject being a girl, aged 10 years 3 months, right-handed, and at the time of this study in her fourth school year (Grade 4). The subject's verbal and non-verbal IQ scores and additional assessment data were analyzed and summative responses given. The Senior South African…
