Research on the determinants of intelligence and factors that relate to variability in intellect are discussed. It is argued that studies in this area usually focus on individual determinants and rarely reflect the true nature of the processes through which variability in determinants relates to variability in intellectual development. (SLD)

J.H. Kranzler and A.R. Jensen report on a reanalysis of previous data that is again inconsistent with the hypothesis that psychometric "g" is unitary. J.B. Carroll reiterates objections to the evidence that Kranzler and Jensen offer in support of a composite "g." (SLD)

Describes why birth order interests both parents and researchers, discussing what really causes apparent birth order effects on intelligence, examining problems with using cross-sectional intelligence data, and noting how to move beyond cross-sectional inferences. Explains the admixture hypothesis, which finds that family size is much more…

Jean Piaget's theories about the development of intelligence and their implications for educational practice are explored. Before Piaget began studying the intellectual processes of children, researchers regarded them as "little adults." He derived his early fame from his theory of the "cognitive stages" of childhood. He…

Discusses the patterns of mental development of 350 pairs of twins studied longitudinally from 11/2-6 years of age. (DP)

There is considerable controversy as to why middle-class youngsters outperform lower-class youngsters on most measures of academic ability. This article examines the differences between two prominent views as to why this disparity exists. (Author/HMV)

The relationship between learning ability and intelligence has continually been a focus of theory and research. It is argued in this paper that the inconclusive results of studies relating individual differences variables such as intellectual abilities to learning are due to a too pragmatic, theoretical orientation. Theoretical models explicating…

In a sample of children with significant learning disabilities, it was found that those born in warm months had higher IQ's than those born in cold months. The effects of temperature and humidity upon neonatal cortex development are offered as a possible explanation of the differences noted. (ST)

Describes formulation of distancing hypothesis, and introduction of the terms distal and distancing, reflecting interaction between understanding origins of intelligent behavior, which is genetic epistemology, and the education of the child. (Author)

Argues that the mission of the university is to create intelligence. Defines intelligence, discusses research on cognitive processes of learning, and discusses obstacles to using the demonstrate-label-coach-mastery strategy emphasizing the value of the clinical approach used to teach seven specific skills. Presents a classroom illustration of this…

In January, W. H. Brady Scholar Charles Murray stepped back from current education debates about reauthorization of the 2002 No Child Left Behind Act and education funding in the president's budget to ask more fundamental questions about the goals that should shape American education in the future. This "On the Issues" is adapted from…

Educators must provide conditions which encourage the practice and demonstration of intelligent behaviors. Twelve characteristics of intelligent behavior are discussed, such as persistence, decreasing impulsivity, listening to others, metacognition, questioning and problem posing, etc. A summary of the school conditions in which intelligent…
