The role of ‘action-effects’ and agency in toddlers’ imitation

We report an experiment on imitation by children between 14 and 26 months in which the presence or absence of an outcome of the procedure to be imitated was varied against whether the procedure was one performed by the experimenter or by a descending arrow. The presence of an outcome did not affect performance positively when the procedure was performed by the experimenter, but it did when it was performed by the descending arrow. When there was an outcome, performance on the experimenter-perform and the arrow-perform conditions did not differ. We argue that this result puts pressure on theories like ‘the theory of common coding’ (W. Prinz) which view the presence of an outcome as being crucial to imitation.
