Looking-time studies examined whether 11-month-old infants can individuate two pairs of objects using only shape information. In order to test individuation, the object pairs were presented sequentially. Infants were familiarized either with the sequential pairs, disk-triangle/disk-triangle (XY/XY), whose shapes differed within but not across…

This study examines the effects of sex, socioeconomic status, birth order and birth spacing on the cognitive performance of 12-week-old infants. A brief review of research on neonatal cognitive ability is followed by a description of the study itself. The subjects, 189 three-month-old Caucasian infants (61 first borns, 58 second borns, and 49…

Twenty infants, 12 weeks of age, were subjects in an experiment to test the effects of maternal behavior on their perceptual-cognitive development. Each mother and child were observed in a controlled naturalistic setting, every 10 seconds their various behaviors were recorded, and then the mother was interviewed. During an experimental session the…

The focus of the study reported here is on two issues: whether the two most elaborate systems of natural observation, that is, those developed by Escalona and Watts could be applied to mother-child interaction recorded in a teaching situation; and whether there are relationships between maternal-child behavior so observed, and a more extended…

This book contains a collection of papers that focus on normal infant development, particularly from the standpoint of learning. Written by leading experts from a member of disciplines, these papers deal with topics such as: the examination and observation of infants, including neurological, neuropsychological, and neurobehavioral aspects;…

Recent research points to the inborn abilities of infants and shows how early experiences influence cognitive skills. This book presents activities for parents and their infants--building on activities babies instinctively love--to develop their unique abilities. The book is organized around six intellectual skills: (1) problem solving; (2)…

The Infant Health and Development Program was an eight-site randomized controlled trial of comprehensive early intervention for low birthweight, premature infants from birth to age three. Higher mental development and IQ were associated with high levels of intervention participation at 24 and 36 (but not 12) months. A dose-response relation…

Examines the role of language in providing individual quality care to infants in a group situation. Suggests that by using language, the natural medium of choice, the adult includes the infant in his caregiving, and this inclusion helps to set up the beginning of a network of communication that lays the foundation for mutual understanding between…

Examined predictors of development in very low birth weight infants from diverse backgrounds. Found that low income and greater frequency of medical problems predicted developmental risk on the Bayley Scales. In two-parent households, paternal education predicted developmental scores. Several individual biomedical factors predicted…

The 14 articles, which make up the bulk of this book provide an interdisciplinary guide to the management of very low birth weight infants. Following an introduction, the first section, titled "Family Considerations," presents three papers discussing, respectively, parent-infant interaction, cultural variables in pediatric care, and parents'…

Studies on the effects of early day care can be characterized according to two distinct research trends. In the first, which occurred during the 1960s and 1970s, the principal issue was whether day care had any inevitable and negative consequences for the child and, particularly, the mother-child attachment. The second, more recent, trend has been…

Annotations of tests measuring motor development, cognitive growth, intelligence, mental health, social maturity, and concept attainment in infants from birth to 24 months of age are presented. Information is given concerning test purpose; intended groups; test subdivisions or tested skills, behaviors, or competencies; administration; scoring;…

Noting that the last 30 years have seen enormous increases in the understanding of infancy, this book examines the current state of knowledge regarding infant development. The book's contents stem from meetings of the British Infancy Research Group. Although the book was intended for advanced undergraduates, it would also be useful for advanced…

Two experiments explored the existence and the development of relations between action representations and object representations. A priming paradigm was used in which participants viewed an action pantomime followed by the picture of a tool, the tool being either associated or unassociated with the preceding action. Overall, we observed that the…

This article presents an argument, based on psychological research and inferences about human evolution, for the plausibility of an intrinsic altruistic motive. A theoretical model for the development of such a motive is outlined. (JMB)
