This study investigates the association between home computer experience and cognitive development among preschool children in inner-city Head Start programs. Approximately 200 children enrolled in four Head Start centers in Detroit, Michigan were recruited to participate in this study. Data was collected from parents regarding the children's experience with computers in the home environment, including their access to a computer, the amount of time spent on the computer, and types of programs used on the computer. Each child was assessed using the McCarthy Scales of Children's Abilities (MSCA) and the Boehm Test of Basic Concepts, Third Edition Preschool (Boehm-3). Results suggest that using a computer is positively correlated with some aspects of cognitive development. After controlling for parent's education and household income, children who had access to a computer in their home had significantly higher scores of the Verbal, Perceptual-Performance, and General Cognitive scales of the MSCA. Furthermore, frequency of children's computer use was related to scores on the Boehm-3. These results suggest that early computer use at home may be a positive influence in young children's cognitive development. (Contains 5 tables.)

An increasing proportion of newly diagnosed AIDS cases is being reported among African American urban women. Recent research regarding the psychosocial and behavioral impact of a mother's HIV status on her uninfected children as well as a growing body of clinical evidence suggest that these children are extremely vulnerable and at risk for problems in psychosocial adjustment. The present paper reports the results of research designed to examine the pathways by which a mother's HIV-positive status affects the psychosocial adjustment of her uninfected school-age child. The principal predictor variables of the model are family sociodemographic characteristics, social support available to mother and child, HIV-related symptom distress in the mother, coping strategies of both mother and child, emotional distress of the mother, and quality of the parent-child relationship. The dependent variable is the psychosocial adjustment of the child. Data were collected on 147 mother-child dyads using standardized questionnaires and personal interviews. Eighty-six percent of the mothers were African American and over 96% were on public assistance. Structural equation modeling was used to test the proposed model of mother-child coping and adjustment. After adding three paths, the model had a good fit to the data (comparative fit index = 0.94; root mean square estimate of error = 0.06). Five model constructs accounted for 36% of the variance in child adjustment. The constructs in order of importance were maternal HIV-associated stressors, maternal emotional distress, child social support, child coping, and quality of parent-child relationship. rights reserved.

Four-year-old children exposed prenatally to polychlorinated biphenyls (PCBs), an environmental toxin, were assessed on three tasks - two designed to evaluate cognitive processing efficiency and one to evaluate sustained attention. When compared with standardized IQ tests, these tasks provided greater specificity in identifying cognitive deficits. Adapted for 4-year-old children in the present study, these paradigms demonstrated moderate levels of test-retest reliability. Prenatal exposure to PCBs was associated with less efficient visual discrimination processing and more errors in short-term memory scanning but not with sustained attention. Although much larger quantities of these contaminants are transferred postnatally via breastfeeding than prenatally across the placenta, postnatal exposure was unrelated to cognitive performance. The data link intrauterine PCB exposure to two dimensions of cognitive functioning fundamental to learning.

In this study we used structural equation analysis to examine the relationship between chronic illness and depression among urban women. The model included the number of chronic illnesses reported, the demands of illness, perceived social support, and salient demographic variables as predictors of depression. The number of chronic illnesses had no direct effect on depression but had a direct impact on the demands of illness which led to decreased social support and increased depression. Being married played a protective role by reducing depression both directly and indirectly through increased social support. Having children under 18 in the home increased depression by increasing the demands of illness. These results provide important information about women with chronic illness and their resultant risk of depression. [ABSTRACT FROM AUTHOR]
