The Picture Exchange Communication System (PECS) was developed in 1985 as a unique augmentative and alternative training package that teaches children and adults with autism and other communication deficits to initiate communication. First used at the Delaware Autistic Program, PECS has received worldwide recognition for focusing on the initiation component of communication. PECS does not require complex or expensive materials. It was created with educators, resident care providers and families in mind, and so it is readily used in a variety of settings.
PECS begins with teaching a student to exchange a picture of a desired item with a "teacher" who immediately honors the request. The training protocol is based on B.F. Skinner's book, Verbal Behavior so that functional verbal operands are systematically taught using prompting and reinforcement strategies that will lead to independent communication Verbal prompts are not used, thus building immediate initiation and avoiding prompt dependency. The system goes on to teach discrimination of symbols and then how to put them all together in simple sentences. In the most advanced Phases, individuals are taught to comment and answer direct questions. Many preschoolers using PECS also begin developing speech.
Creative Teaching CAP incorporates the Picture Exchange Communication System (PECS) through the use of 'picture symbols' to visually set expectations and establish routines. CAP's Student Schedule Books are designed to be used with both CAP picture symbols and Boardmaker symbols for use at school and at home. We also utilize picture symbols to initiate communication.
