Infants in four age groups--three, six, nine and twelve months--were exposed to an experimental procedure designed to assess the extent to which such subjects were capable of discriminating between different orientations of the same form, and the extent to which they were capable of recognizing the identity between different orientations of the…

The development of two temperamental characteristics--the tendency to approach (uninhibited) and the tendency to avoid (inhibited) unfamiliar events--may be partially controlled by genetic predisposition. Discusses the results of a study indicating that the level of motor responses and crying in response to unfamiliar stimuli in four month olds…

This illustrated booklet describes the physical, social, cognitive, sensory, and motor development of the typical infant during the first 12 months of life. Each of 12 chapters is concerned with successive months in a child's first year and is divided into three sections. Specific stimulating activities (i.e., handing toys to the infant's…

Function of attention in infants is explored. Assuming (1) that infants respond differently to novel situations than to familiar ones; (2) that the infant's pattern of response is a partial reflection of the process of acquiring a perceptual memory of the stimulus, and (3) that sex differences may occur in the rate of habituation, 120 infants…

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 development of and relationship between early language, symbolic play, sensorimotor skills, and social development were examined in a longitudinal study conducted in Japan with two young autistic males who were observed from the approximate ages of 2 to 4 years in clinic, day care, and home settings. One child acquired speech; the other did…

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…

Describes a program developed to help parents become effective playmates. Suggests that interactive play between infants and adults has numerous benefits, although these benefits will not occur automatically; they require parents to develop the appropriate skills. Proposes methods to facilitate play and make an important contribution to the…

This book consists of 31 papers focusing on aspects of child development. Mainly reports of research, papers are grouped topically into four sections dealing respectively with perceptual, language/communication, cognitive, and social development. Most of the nine papers in section 1 focus on the perceptual development of infants. Topics include…

This paper presents two studies of the development of social competencies in infancy. In the first experiment, the central issue investigated was whether facial configuration or height is utilized by infants to respond differentially to children and adults. Five different strangers, a male and a female child, a male and a female adult, and a small…

This paper describes the purposes and procedures of a longitudinal study designed to: (1) relate mother-infant interaction patterns to infant age, sex, and social class; (2) relate mother-infant interaction patterns to infant sensory-motor development; and (3) to examine the relationship between infant sensory-motor development and infant sex and…

The development of sensory and perceptual ability in infants is an important area of infancy research. This book reflects current knowledge of perceptual development and points to some of the many questions that remain unanswered. The book is divided into four parts. Part 1, "How the Visual System Develops: Normal and Abnormal…

Discusses the need for communication between parents, caregivers, and infants in high quality caregiving. Emphasizes the importance of a developmentally appropriate program. Addresses primary caregiving in terms of the overall care and nurture of a small group of infants. Discusses methods of reporting and assessment used by caregivers. (GLR)

This monograph is a collection of papers describing a series of loosely related studies of visual attention, auditory stimulation, and language discrimination in young infants. Titles include: (1) Infant Attention and Discrimination: Methodological and Substantive Issues; (2) The Addition of Auditory Stimulation (Music) and an Interspersed…
