Infant imitation: The sensory-motor agenda.

Six different actions were demonstrated by the 2nd author to 9 infants once a month between the ages of 6 and 12 mo. Each action was presented many times, with each trial contingent on the S's making eye contact with the experimenter. From videotapes, 21 categories (CAs) of infant behavior were coded continuously. Each CA could be considered a component act or feature of one of the modeled actions. All CAs were coded during all parts of the session: baseline periods, trials of the tasks of which they were features, and trials of the other tasks. Ss did not confine their performance of features to the relevant trials as construed by the authors, but they did accelerate or introduce features for the first time during those trials. Analysis showed that the Ss "worked up to" precise imitations by accommodating themselves to the features in a consistent order over both months and trials.
