Face scanning is an important skill that takes place in a highly interactive context embedded within social interaction. However, previous research has studied face scanning using noninteractive stimuli. We aimed to study face scanning and social interaction in infancy in a more ecologically valid way by providing infants with a naturalistic and…

Two experiments were conducted to test effects of infants' ability to locomote on their social and exploratory behaviors. Results indicated that walker-assisted or independent locomotion afforded similar experiences within a standard environment but experiences quite different from those of the nonlocomoting infant.

Ten-month-old infants in an unfamiliar environment with their mothers were left free to approach and touch a distant, unfamiliar object-a person or a toy. Results suggest that looking at persons constitutes exploratory behavior whereas touching and manipulating served this function with inanimate objects. (CS)

Examines early differences in mother-infant interaction as a function of infant birth order and birth spacing. Mother and infant behaviors were observed and recorded in the home for a two-hour period. (SS)

Previously published data on infants aged 12 and 13 months who were observed in the Strange Situation with their mothers and fathers were reanalyzed using a component process approach. (PCB)

Infant-toy and infant-adult interaction were observed in four conditions which varied the degree of adult-toy manipulation. Subjects were 48 infants 11-13 months of age. (Author/SS)

Investigates infant preferences for interaction with mother v father, similarities and differences in maternal and paternal behavior, and the influence of a second parent's presence on parent-infant interaction. Families with infants 15 months of age were observed in their own homes. (Author/SS)

A twin analysis was applied to infants' social behavior in standardized situations that permitted the comparison of social responding to mother and a stranger in different contexts. Twenty-one identical twin pairs and twenty-five fraternal twin pairs were observed in their homes using time-sampled observations of specific behaviors. (Author/SS)

Considers contributions of Sigmund Freud and Rene Spitz to developmental psychology. Freud's contributions include his observations about play, perspectives on developmental processes, and ideas about unconscious mental activity. Spitz's contributions include his assessments of infants, perspectives on developmental processes, and his concept of…

Reports an analyses of ratings on Bayley's Infant Behavior Record and test scores from the Bayley Mental Scale for 60 female and 50 male infants at 6, 12, 18 and 24 months of age. Results are discussed in terms of rank-order correlations, behavioral composite scores and study implications. (Author/SDH)

Compared with fathers, mothers were more likely to pick up and hold infants, feed and comfort them, and invest time in displaying affection. Although there were sex differences in parents' rough and peek-a-boo play, mothers and fathers treated boys and girls quite similarly. (RH)

A cross-national comparison of infant behavior in the Strange Situation was designed to determine whether preseparation episodes made any difference in attachment classifications and whether infant behavior before separation from mother was the same in different countries. Infants in different countries made similar primary appraisals of the…
