Procedure of the deferred imitation task. During the baseline phase, infants were allowed to explore the toy and it was recorded whether or not they performed the target action during this phase. In the demonstration phase, the experimenter modelled the action three times. Half of the items were then given back to the infant immediately after demonstration (immediate imitation phase). After a 20 min delay infants were presented with all six items (deferred imitation phase). Which half of the items was included in the immediate imitation phase was counterbalanced across infants.
