Indicates that 18- to 20-month-old infants can detect the correspondence between auditorially and visually perceived speech; that is, they manifest some of the components related to lip-reading phenomena in adults. This demonstration of the bimodal perception of speech in infancy has important implications for social, cognitive, and linguistic…

Reports on a study in which the symbolic relation between a scale model and the larger space that it represents was displayed by two groups of young children. Three-year-old children outperformed 2.5-year-olds in finding an object in a room after seeing an analogous object hidden in a model. (TW)

The author's purpose in this article is to discuss the aspects of language (especially the development of language in children) to which biological concepts are most appropriately applied. While results of past studies would seem to show that language development is contingent on specific language training, it is important to distinguish between…

This study of young men from two-child families shows that birth-order effect and level of ability were not influenced by length of interval between firstborn and secondborn. (MP)

Reports the results of studies of perception of very young infants. Sixty infants 6 to 23 days old were presented objects; looking-at and reaching-for the objects were measured. Results indicated active visual exploration of objects did occur; however, little motor activity was directed toward the objects. (SL)

Describes the reaction of infants and their attention to events by actions such as vocalizing, smiling or a change in respiration rate. Suggests that understanding of infant selectivity and duration of attention should provide insight into the nature of psychological growth. (JM)

Presents the procedures, results, and conclusions of two studies conducted to investigate the process of children separating from their mothers. The authors suggest that this kind of behavior has important biological and psychological consequences, among which are increased opportunities for learning and for adaptation to the environment, on the…

Discusses research related to identifying early predictors of school success or intelligence. Reports on a study that suggested correlations exist between how babies process information (visual attentiveness) in the first six months of life and the child's performance on intelligence tests in school.

Research shows that children of about 10 years can remember photographs of faces upside down almost as well as those shown upright and are easily fooled by simple disguises. This ability to encode orientation-specific configurations of a face may reflect maturational changes in the right cerebral hemisphere. (MLH)

A discussion of the relationships, both biological and behavioral, among nutrition, population, and health in relation to government policy. Special emphasis is given to breast feeding and child survival. (BB)
