A psychobiosocial model that is based on the inextricable link between the biological bases of intelligence and environmental events is proposed as an alternative to nature/nurture dichotomies. Societal implications and applications to teaching and learning are suggested. (MMU)

The research results indicate that, although sex differences in mathematical abilities are not pronounced before high school, for some reason by the end of that period boys do better than girls in mathematical computation and problem solving. Environmental and biological explanations, intervention strategies and further research needs are…

Examined changes in intelligence in Negro children at ages 4 and 7 as a function of sex, home stability and educational level of their parents. Results were interpreted as supporting an interaction hypothesis concerning the relative effects of heredity and environment on intelligence. (DP)

Examined divorce and gender as factors in racial differences in performance of elementary age children on Hahnemann Elementary School Behavior Rating Scale, Wechsler Intelligence Scale for Children-Revised, Wide Range Achievement Test, Vineland Teachers Questionnaire, and an interview. Found more racial group differences within the divorced…

The author's previous article was intended to demonstrate that research on intellective sex differences (SDs) was incomplete because of a general preoccupation with SDs in means. SDs in central tendency and SDs in variability must be considered together to comprehend differences between male and female distributions in abilities. (SLD)

This paper examines evidence supporting the hypothesis that environment differentially affects intelligence in a sex-specific manner. The current position that environment and heredity contribute interactively to intelligence obscures the greater vulnerability and exposure of males to environmental influences and the reciprocal lack of equivalent…

Drawing upon the burgeoning research in neurology, as well as stories of real children, this book charts the brain's development, from conception through the critical first 5 years of life. In examining the many factors that play crucial roles in that process, the book explores the evolution of the senses, motor skills, social and emotional…
