Children's imitations were analysed as a function of parental speech acts for six children in early Stage I of language acquisition. The relative frequency with which children imitated mothers reflected the relative frequency with which mothers imitated children (Spearman rank correlation = 0·77). Although parents' imitative expansions could all be categorized as having primary speech act functions (e.g. request for information) from the parents' point of view, expansions constituted a separate class of speech events in terms of children's responses. The children imitated imitations far more frequently than non-imitative speech acts in the same category. These findings suggest that individual differences in children's propensity to imitate may arise from the degree to which parents provide a model of imitation as a speech act.
