In this clip, you will see a therapist modeling an action for imitation about once every one to two minutes. She models an action for imitation with the activity that the child is already engaged in, in order to increase the likelihood that he will imitate. When he does not imitate after the third model, the therapist physically guides the child to complete the action. Notice that once the steps for teaching object imitation have been completed, the therapist goes back to imitating the child’s behavior. Towards the end of the clip, she imitates his vocalizations and sound effects and he turns this into a fun social game.
