Provides a foundation for future experimental research on the origins in mother-infant interaction of sex differences in the development of a separate sense of self. Suggests that sex differences in the experience of a separate sense of self begin to emerge in early infancy and that mothers engage in different types of contact with sons and…

Results suggest that infants' errors in searching for a visible object reflect lapses of attention rather than systematic misunderstandings of objects or space and so are not incompatible with an information-processing account of early search. (Author/RH)

It was hypothesized that infants' examining behavior, in contrast to other activity, reflects focused attention and active intake of information. The first study with 7- and 12-month-olds supported the hypothesis. The second and third studies investigated the effects of age and familiarity on both latency to and duration of examining.

Social smiles of 10 visually impaired 4 to 12 month olds were examined longitudinally in play interactions with their mothers. All infants demonstrated both the presence of social smiles and the second Piagetian stage of cognitive development at the start of the study. Social smiling increased in frequency from 6 to 12 months. (Author/CB)

The behaviors of 57 mothers, their preschool-age children, and their infants were observed using a modified "strange situation" to explore the older siblings' potential to act as subsidiary attachment figures. Gamelike tasks were used to assess the conceptual perspective-taking abilities of the older children. (Author/RH)

Describes an experiment which tested the infant's sensitivity to the timing of the mother's responses by arranging a video system so that mother and baby each saw a full-face, life-size image of the other on a video screen. Results provide evidence for the infant's active role in interaction with adults. (SED)

Presents a framework delineating four influences on infant and family development: personality, social interaction, role, and ecology. Documents stable characteristics of parents' personality and marriage that affect family development and infant soothability. (Author/CB)

Argues (1) that Feinman (1982) and Campos (1983) agree that 10-month-old infants are able to use their mother's emotional expression to come to an appraisal of a third event and (2) that this claim is supported by studies of mother-infant interaction and communication. (Author/RH)

A total of 192 high-risk infants and 85 full-term healthy newborn infants were administered the Bayley Scales of Infant Development. A principal component analysis was performed separately for the high-risk and control infants. Results suggest that the high-risk infant is similar to the normal infant in behavioral development, especially when…

This article emphasizes the importance of studying prelinguistic communication in infants. Motor development and environmental influences are seen to be important aspects of linguistic development. The possible link between sensorimotor activity and the syntactic structure of language development needs further exploration. (MS)

In this study, an attempt was made to determine whether psychophysiological differences existed between 20 prematurely born and 20 full-term infants in their responsiveness to tactile stimulation and in their ability to discriminate among different intensities of such stimulation. (Author/SB)

This research disputes the traditional position on babbling by showing that the phonetic content of babbled utterances exhibits many of the same preferences for certain kinds of phonetic elements and sequences that have been found in the production of meaningful speech by children in later stages of language development. (Author/RM)

Scientists believe that the stimulation that infants and young children receive determines which synapses form in the brain. This book presents 125 games for infants from birth to 12 months and is designed to nurture brain development. The book is organized chronologically in 3-month increments. Each game description includes information from…

Infants ranging in age from six months to eight months were shown repeated instances of real object movement-disappearance-reappearance. Results suggest that the key changes in early cognitive development rest primarily upon the infant's gradual adaptation of old responses through encounters with new events--rather than upon the acquisition of…
