Introduction

A picture exchange communication system (PECS) is a form of augmentative and alternative communication (AAC) that uses pictures instead of words to help children communicate. PECS was designed especially for children with autism who have delays in speech development.

When first learning to use PECS, the child is given a set of pictures of favorite foods or toys. When the child wants one of these items, he gives the picture to a communication partner (a parent, therapist, caregiver, or even another child). The communication partner then hands the child the food or toy. This exchange reinforces communication (1-4). PECS can also be used to make comments about things seen or heard in the environment. For example, a child might see an airplane overhead, and hand a picture of an airplane to his or her parent. As the child begins to understand the usefulness of communication, the hope is that he will then begin to use natural speech.

A child can be trained in PECS by a parent, caregiver, or therapist who has learned about the method (see Resources). An applied behavior analysis (ABA) approach is used, in which prompts are given to guide the picture exchange. Further, in the early phases of PECS training, the child chooses a picture of a desired food, and receives the food in exchange for the picture. Getting the food is the positive reinforcement for using the picture to communicate.

The communication partner makes a list of the child's favorite items (usually beginning with foods). One of these items is selected for the first training session, and a picture of the item is made. That item can be placed under a clear container, so the child can see it, but not ...
