In contrast with controls and newborn presented with static models, only newborn presented with dynamic models reproduced the models' actions at significant levels. Infants in the static condition fixated the experimenter longer than those in the dynamic one. Results are discussed in terms of neurophysiological findings concerning the control of…

Results of two experiments indicate that dimensions of the social situation in which social behaviors are modeled influence eight-month-old children's tendency to imitate and their choice of recipients for their imitation. (Author/RH)

The behavioral dynamics of three different types of early mother-infant interactions were examined. Mothers were instructed to play with, imitate, and hold the attention of their infants. Frequency of vocalization, gaze direction, and smiling by both interactants, tactile play by the mother, and crying by the infant were recorded. (PCB)

A laboratory procedure was developed for assessing imitation in the second year of life. Results demonstrate that 14- and 24-month-olds can imitate a simple action with an unfamiliar object, both immediately and after a 24-hour delay. Implications for research design and theory of infant memory are discussed. (RH)

Ability of 26 newborns to imitate facial expressions was examined. When infants observed emotional facial expressions, they did not show imitative matching of the modeled expressions. However, when tongue protrusion was modeled, infants did produce the modeled gesture. (PCB)

Investigates ability of nine-month-old infants to imitate simple actions with novel objects. Looks at both immediate and deferred imitation. Findings show that imitation in early infancy can span wide enough delays to be of potential service in social development. (Author/RWB)
