Presents a descriptive analysis of infant-adult face-to-face interaction, as well as the data for analyses of the relations between the two partners and the contribution of each one during the interaction. Subjects were five infants (aged 80-92 days) and their mothers. (MP)

Discusses the social development of infants in terms of a set of tasks which include identity, culturation, and reproduction. Focuses on the task of identity, the role of self-awareness in relationships, and the relationship between identity and emotional life. (RJC)

Develops a classification system for the physical environment based on 3 dimensions of stimulation. Intercorrelations of physical and social environmental measures obtained for 88 infants of 12 months supported the validity of the decision rule that nonresponsive animate stimulation is primarily physical rather than social. (RJC)

Summarizes study findings related to the effects of continuous monotonous stimulation on sleep and its physiological parameters in early infancy. (ED)

An account of studies conducted by author and others concerning Piaget's view of object concept development in infants. (HS)

Compares infants' performance based on chronological age as opposed to conceptual age. The Bayley Mental Scales were used to test 20 premature experimental infants and 20 full-term control infants. Results demonstrated that an infant's performance must be judged on the basis of conceptual rather than chronological age. (MS)

Discusses important recent strides in the documentation and understanding of the infant's learning and memory capacity. Focuses on the psychobiology of learning, hedonic mediation of approach-avoidance and learned behavior, infant memory, and critical conditions of infancy and behavioral misadventures. (RJC)

Two experiments investigated 8-, 10-, and 12-month-old infants' levels of searching for mothers, strangers, and objects. Found that, overall, 10- and 12-month-old infants had higher levels of searching for mothers, whereas youngest infants showed no differences for searching. This discrepancy is likely due to social cognitive development and…

Demonstrates that eye contact per se, and not solely the inherent attractiveness of the eyes and face, is salient to five-month-old infants. Five-month-old infants can distinguish when another person is looking at them, rather than at a nearby location. (Author/MP)

As an important part of the plan to record and systematically deal with all observable behavioral events that constitute an infant's waking life, all social encounters between the baby and other persons that occurred during weekly observations of two infants in their everyday milieu were recorded. (Author/CB)

Portions of this paper were read as part of a symposium on The Meaning of Smiling and Vocalizing in Infancy'' at the 1970 meeting of the American Psychological Association, Miami Beach, Florida, September, 1970. (Editor)

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)
