In an effort to isolate the emergence and causes of social class differences in intellectual performance, this longitudinal study was undertaken as a follow-up on a cross-sectional study that yielded no social class differences on the Cattell Infant Intelligence Scale for 12-, 18-, and 24-month-old black children. In the present study, 89 children…

This collection of essays about intelligence stems from the revived nature-nurture controversy about the origins of mental abilities, led notably by Arthur Jensen, whose article in 1969 created a furore in the U.S.A., and more lately by H. J. Eysenck in Britain. In planning this book, an attempt has been made to step back from the debate itself…

Reports on a longitudinal study of cognitive and motor development among infants born to adolescent and adult mothers when race, parity, socioeconomic status and prenatal care were controlled and home environment evaluated. (HOD)

A sample of 25 children exposed prenatally to cocaine was compared with a control group of 18 children not exposed to any drugs prenatally. Using the AGS (American Guidance Service) Screening Profile, results indicated that the control group was significantly superior on all subtests except for the Motor Coordination and Speech Articulation…

The seven cohort studies of the relation between prenatal and postnatal exposure to polychlorinated biphenyls (PCBs) to cognitive, neuropsychological and behavioral development have suggested that exposure to PCBs can cause persistent changes in cognitive functioning. D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (this issue) apply six scientific…

In this paper we address the points raised by groups of scientists who were invited to respond to our initial critique of polychlorinated biphenyl (PCB) research in this special issue. In that article, we applied six objective criteria to more than two decades of published PCB research and concluded that much of the research was badly flawed. The…

This bibliography on nutritional disorders and child development is directed towards early childhood professionals outside the field of nutrition. The main topic covered pertains to malnutrition and undernutrition as it relates to mental/intellectual/cognitive development of children from the fetal stage through the early childhood years. Included…

Thirty-four children (ages 5-16) born to alcoholic mothers were assessed on measures of intelligence, reading, receptive vocabulary, memory for sentences, visual memory, and visual-motor integration. The children were found to be least deficient on intellectual measures and most deficient on memory for sentences and silent and oral readings.…

Our purpose in this report is to evaluate scientifically that body of literature relating the effects of prenatal and postnatal exposure to polychlorinated biphenyls (PCBs) upon neurobehavioral, health-related, and cognitive deficits in neonates, developing infants, children, and adults. The data derive from seven cohorts: six cohorts of mothers…

The aim of the review of D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (funded by the General Electric Company; this issue) is to "evaluate [the] literature relating the effects of prenatal and postnatal exposure to polychlorinated biphenyls (PCBs) upon neurobehavioral, health-related, and cognitive deficits in neonates, developing infants,…

This invited response to the paper by D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (CKS), and the responses by the investigative teams of the studies criticized by them, addresses specific errors of logic and interpretation by CKS, and integrates comments made by the study investigators. CKS provide a flawed analysis of the literature on the…

We need to find out the extent to which individual differences, social class differences and race differences in rates of cognitive development, and differential patterns of relative strength and weakness are attributable to genetically conditioned biological growth factors. The answers to this question might imply differences in our approach to…

Malnutrition can be defined as a lack of a sufficient quantity or quality of nutrients to maintain the body system at some definable level of functioning. It has been estimated that nearly half the children in the world today grow and develop under conditions of protein or protein-calorie malnutrition sufficient to impair their physical…

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…

The degree to which under nourishment exists in a local community such as San Diego, California, and in the U.S. at large, and whether it is severe enough to interfere with brain development is the focus of this report. After establishing criteria for nutrition intake that would represent unambiguous jeopardy to brain development, these criteria…
