Picture Exchange Communication System
PECS is a unique alternative/augmentative communication system designed for preschool students diagnosed with autism. PECS is used with learners of all ages who have various cognitive, physical and communication challenges. Specific prompting and reinforcement strategies that are designed to lead to independent communication are used throughout the protocol. The protocol also includes systematic error correction procedures to promote learning if an error occurs. Verbal prompts are not used, thus building immediate initiation and avoiding prompt dependency.
PECS consists of six phases and begins by teaching an individual to give a single picture of a desired item or action to a "communicative partner" who immediately honors the exchange as a request. The system goes on to teach discrimination of pictures and how to put them together in sentences. In the more advanced phases, individuals are taught to use modifiers, answer questions and comment.
The primary goal of PECS is to teach functional communication.
