Object play yields enormous benefits for infant development. However, little is known about natural play at home where most object interactions occur. We conducted frame-by-frame video analyses of spontaneous activity in two 2-h home visits with 13-month-old crawling infants and 13-, 18-, and 23-month-old walking infants (N = 40; 21 boys; 75%…

Temporal stability of play behavior and its consistency among toys differing in complexity was assessed by observing 40 eight-month-old infants. The relationship of stability of play to temperament was examined. Findings support the idea that behavioral consistency in infancy is similar to that reported for older children. (RH)

Twelve pairs of previously unacquainted 6-month-old infants were observed in the presence and absence of toys; interactive episodes beginning when an infant touched the peer or a toy held by the peer were examined. Results suggested that young peers influence each other's behavior, but the extent to which they do so depends on situational…

Mothers of 48 infants approximately 12 months old displayed either positive or neutral affect while their infants responded to pleasant, ambiguous, or aversive toys. On the first trial maternal affect had no effect; on the second trial, positive maternal affect resulted in more positive infant responses, but only for the ambiguous toy. (Author/RH)

Studied were the responses of infants to new toys presented with either positive, negative, or neutral affective displays by mothers. Responses to stimulus toys were compared with responses to free play toys. Maternal displays influenced responses only to stimulus toys. (PCB)

Results showed that infants as young as 10 months of age are responsive to the person and behavior of an unfamiliar peer and that they are no less responsive than older infants (22-24 months of age) to the social versus nonsocial aspects of a novel setting. (Author/JMB)

A sample of eight 19-month-old toddlers were observed during free play at home, with and without a familiar toddler playmate. With the peer present, there was significantly more high-level play with toys and less low-level play with toys than with the peer absent. (Author/JH)

Three questions are addressed: (1) Are infants as young as six months capable of interacting with a peer? (2) What type of social acts are used during these early encounters? and (3) Do toys facilitate the interactions? (Author/MP)

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…

The distressed vocalizations of six-month-old infants interacting with peers in a playroom were statistically independent of the peer's vocalizations of distress. Absence of toys reliably predicted the extent of the infant's distress, whereas psychomotor development and sex did not. (Author/ DB)
