Infants between 4 and 21 weeks of age participated in two experiments involving the modeling of from 3 to 5 gestures. Frequencies of infants' reproduction of a modeled act were compared against baseline frequencies and against average frequencies of the act during periods when other actions were modeled. Suggest that imitation of gestures was…

Infants averaging 5 weeks and 12 weeks of age were presented with object models and a live model to determine whether infants reliably responded to the models with movement-matching facial gestures. Object models produced no reliable elicitation of gestures, but the live model increased the incidence of gestures among infants of five weeks. (SH)

Deferred imitation of object-related actions was studied at two ages, 12 and 18 months, to examine development of competence in observational learning. Three task categories were investigated: simple/single reiterative, and sequentially coordinated actions. Examination of partial successes at both ages was useful for suggesting phases in…

Describes research on young children's long-term memory under 2 conditions of acquisition: direct imitation followed by a 10-minute delay, or deferred imitation. Children were able to encode and retain as much from visual pickup of modeled acts as from feedback obtained through imitation. (Author/GH)
