Bryce is a 5-year old who is non-verbal and exhibits aggressive behavior. How can we give Bryce a "voice"? The AT Team met and decided to implement a PECS to support Bryce's communication deficits. By using a Picture Exchange Communication System (PECS), Bryce will develop the ability to communicate his needs, wants, and ideas about academic content.
Before implementing PECS, the speech and language pathologist needs to assess current communication skills and needs. Prepare pictures/symbols and books based on the pre-assessment.
Complete reinforcer sampling to determine how to best reinforce Bryce for using PECS.
Prepare formative assessments to administer during each of the six phases of the PECS implementation. Also prepare a summative assessment to evaluate whether Bryce's learning objectives have been met after learning the six phases of PECS.
Implement Phase 1: Teaching the Physically Assisted Exchange. When Bryce reaches for a high-interest item, picks up the picture card, hands the card to the communicative partner, and acquires the high-interest item, he is ready for Phase 2.
Implement Phase 2: Expanding Spontaneity. Bryce will increase spontaneity and generalization of the picture exchange. When Bryce is traveling to the communicative partner and the communication book, he is ready for Phase 3.
