Picture exchange communication system (PECS) phases 1, 2, and 3

This video provides an overview for teaching a picture exchange communication system (PECS phases 1, 2, and 3).
A picture exchange communication system is one way to teach someone how to communicate with others using pictures. Since pictures are generally universally understood, this system can be used to request for items, answer questions, comment on the environment, and many more.
Phase 1 teaches the child to request for a preferred item using a picture icon. In this phase the child will learn how to pick up a picture icon, reach towards the communicative partner (for example, parent, sibling, family member, therapist), and release it into their hand.
Phase 2 teaches the child to travel to and from the picture book and to the communicative partner at different distances.
Phase 3 teaches picture discrimination between the preferred item and other items.
This video is for educational purposes. This is a model of teaching and using PECS at home.
