In this hour-long seminar, Pam Marshalla describes the four stages of imitation development as defined by Jean Piaget, focusing on how the stages can be used as a basis for developing sound and word imitation in young children who are non-verbal or nearly non-vocal. Many of these children appear unable or unwilling to imitate sounds and words. Over the course of this hour, Pam shares the specialized methods that she has developed for speech-language pathologists who are working with clients such as these.
