Reports that, even though young infants can discriminate among different facial expressions, there are individual differences in infants' expressivity and ability to produce and discriminate facial expressions. (PCB)

Studied 112 preterm infants to determine developmental changes and stability of individual differences. Results indicate significant developmental gains with age, and highly significant individual stability of performance across age. (RJC)

Analyzes the development of the skill of eating with a spoon in 16 infants of 12-23 months. Discusses the acquisition of a tool-using skill in terms of the emergence of strategies for solving particular problems and the consistency and reliability with which they are deployed. (RJC)

Investigated postural constraints on movement of 15 6-month-old infants. Results suggested that each of the developing capabilities of orienting, reaching, and kicking assumed a specific function for locomotion at the stage of crawling. (RJC)

Uses the still-face paradigm as a framework for examining the range of social regulatory capacities available to infants during stressful times. (PCB)

Proposes an amended timetable for the origins of joint visual attention and offers theoretical alternatives for the development of point. Includes discussions of the origins of intentionality, the emergence of joint attention, the transition to pointing comprehension, the signal cues of different joint-attention cues, pointing comprehension, the…

Maintains that Muller and Overton (1998) challenge the current Zeitgeist regarding infant cognitive development. Suggests that researchers reconsider infants as developing actors in a meaningful environment, not as born philosophers. Notes the need to explore processes underlying key transitions in infancy and the relation between action and…

How do infants come to understand references to absent objects? 14-month-old infants first learned a name for a novel toy, which was then placed out of view. The infants who listened to a story mentioning the nonvisible object, looked, pointed, and searched for it more often than did infants who heard a story using a different name. Their behavior…

A core task in language acquisition is mapping words onto objects, actions, and events. Two studies investigated how children learn to map novel labels onto novel objects. Study 1 investigated whether 10-month-olds use both perceptual and social cues to learn a word. Study 2, a control study, tested whether infants paired the label with a…

Previous research on infant swimming has reported contradictory findings. Cross-sectional observations revealed a disorganized phase between about 3 and 12 months, which was attributed to "cortical inhibition" and implied slow learning (McGraw, 1939). However, training with a single infant during this period revealed rapid acquisition (McGraw,…

This book is the result of efforts by an expert study group, set up by the Association for Child Psychology and Psychiatry, to examine the relationships between infant crying, sleeping, and feeding problems, and to shed light on the developmental and regulatory mechanisms involved. It brings together research from a variety of professional…

Based on PhD thesis submitted to Brown University (June 1967).

AN ATTEMPT TO ASSESS STIMULUS CONDITIONS IN THE ENVIRONMENT OF THE INFANT IN THE FIRST YEAR OF LIFE AND THE IMPACT OF THESE STIMULI ON HIS ADAPTIVE AND SOCIAL BEHAVIORS WAS PRESENTED. INFANTS WERE OBSERVED IN FOUR CHILD-REARING ENVIRONMENTS--RESIDENTIAL, KIBBUTZ, SINGLE-CHILD FAMILY, AND MULTIPLE-CHILD FAMILY. UNDER THEORETICAL ORIENTATION, THESE…

The paper discusses the assessment of infant adaptive behavior and its relationship to the adaptive behavior of the mother, focusing on the discovery of disruption and asynchrony in early mother-infant interaction. The development of the earliest patterns of interaction between mother and infant is discussed, along with the relationship between…

This paper draws together briefly theories and knowledge from research in morphology and cognitive psychology, as well as some hypothetical information from traditional psychiatry, to show the ramifications of play in children's development. Play is defined as any of a wide variety of behaviors through which an individual attempts to discover what…
