Understanding PECS

Picture Exchange Communication System (PECS) is a widely recognized and effective communication system that utilizes pictures to facilitate communication, particularly for individuals with autism or other developmental disabilities. Developed in the early 1980s by Andrew Bondy, Ph.D., and Lori Frost, M.S., CCC-SLP, PECS is rooted in the principles of applied behavior analysis (ABA) to teach children with communication difficulties how to initiate communication using pictures.

What is PECS?

PECS is an augmentative and alternative communication (AAC) system that enables non-verbal individuals to express their needs, wants, and ideas using visual symbols. It provides a structured approach to develop functional communication skills and promote independence. PECS is highly flexible and can be tailored to meet the specific needs of each individual, accommodating a wide range of abilities and communication goals.

The Development of PECS

PECS was first developed in the early 1980s by Bondy and Frost at the Delaware Autistic Program. The system was created to address the communication challenges faced by individuals with autism spectrum disorder (ASD) and has since been utilized for various developmental disabilities and age groups.

The Six Phases of PECS

PECS employs a systematic approach that progresses through six distinct phases. Each phase builds upon the previous one, gradually expanding the individual's communication skills:

Phase Description

  • Phase 1: The individual learns to exchange a picture of a desired item for the actual item [2].
  • Phase 2: The individual learns to use the picture to request a desired item or action by giving the picture to a communication partner.
  • Phase 3: The individual learns to generalize the use of PECS in different environments and with various communication partners.
  • Phase 4: The individual learns to use sentence structure by expanding their communication to combine pictures and create longer messages.
  • Phase 5: The individual learns to respond to questions using pictures, expanding their ability to engage in conversations [3].
  • Phase 6: The individual learns to initiate spontaneous communication by commenting on items, people, or activities using pictures.

By progressing through these phases, individuals using PECS can develop functional communication skills and enhance their ability to express themselves effectively.

Understanding PECS, its development, and the six phases provides a foundation for exploring the benefits, implementation, and future directions of this powerful communication system.
