There is a long-standing controversy over the relationship between psychopathology and creativity. Yet there is a lack of evidence regarding the relationship between common psychopathologies and indicators of little-c, or every day, creativity among laypeople. To make sense of this connection, we conducted a meta-analysis using 89 studies to…

A review of research studies on the effects of fenfluramine as a pharmaceutical treatment for autistic children is presented. Fenfluramine had positive effects on the reduction of hyperactivity and stereotypic behaviors in approximately one-third of subjects. The best responders were children with the highest baseline intelligence quotients.…

To determine whether the idea is empirically supported that the majority of left-handers were intellectually inferior to right-handers, current research was examined. Inquiry indicated that the cognitive performance of left-handers was not significantly lower. (Author/CM)

Responds to "Birth Order and Intelligence: Further Tests of the Confluence Model" by Robert D. Retherford and William H. Sewell. Reviews their arguments and suggests that their analyses of the Wisconsin Longitudinal Study data support rather than contradict the model. (CJS)

Describes a system of categories to subdivide the gifted and talented population into the following more homogeneous subgroups: mild, moderate, high, exceptional, and extreme. Based on the metric system, each of the five levels, including the minimum threshold, selects the top 10% of the previous level. (Author/CR)

Discusses Jensen's research and writings on genetic v environmental determinants of intelligence. Reviews professional response to his 1969 "Harvard Educational Review" article, and briefly considers the work of other researchers on the relationship between race and intelligence. (GC)

In a review of heredity v environment theories, the author concludes that no individual, regardless of potential, can approach the full development of his or her abilities without exposure to an enriched environment. (Editor/SJL)

Summarizes Arthur Jensen's theories on IQ, heritability, and Black intelligence and reviews some responses to Jensen. (JLF)

The entire thesis of "The Bell Curve" disintegrates due to biased use of data, misrepresentations, and logical inconsistencies. Five basic flaws are: inferring causality from correlation, use of dubious racial categories, contradictory arguments concerning the immutability of cognitive ability and the relative contributions of heredity…

This paper summarizes empirical findings of research on a theory of general mental ability, based on laboratory studies of the relationship between measurements of individual differences on conventional psychometric tests and in speed and efficiency of information processes. The paper covers characteristics of "g" (general mental ability),…

A number of studies in the United States have found that Jews obtain higher average IQs than white gentiles. This paper examines whether this is also the case in Britain. Three early studies are summarized that found that Jews in Britain have mean IQs in the range of 110-113. New data are presented for two nationally representative samples of 7-16…

This document is a book review of "Bias in Mental Testing" by Arthur R. Jensen. Jensen discusses intelligence as a phenotypic construct. The problem of ethnic differences in phenotypic intelligence is emotionally charged, which makes rational consideration of the issues difficult. The reviewer disagrees with the author's predisposition…

School psychologists, considered experts on intelligence and assessment, have an ethical obligation to read and understand "The Bell Curve: Intelligence and Class Structure in America." Many would rather avoid than confront issues presented. Discusses four questions to consider before dismissing the book: "How helpful is it?"; "Could the…

The question of how to integrate developmental (Piagetian) and psychometric conceptions and assessments of intelligence is considered. A solution which incorporates the contributions of each position--intelligence as forms and as traits--is offered. Premises and objectives of each tradition are reviewed and compared. Overlaps make synthesis…

Discusses the different characteristics that are often lumped together under the multidimensional term "giftedness." The origins of the term, the contributions of individual psychologists and others in identifying gifted students, and the life outcomes of mathematically and/or verbally precocious youth identified by talent searches are examined.…
