Picture Exchange Communication System (PECS) in Pediatric ABA Therapy

The Picture Exchange Communication System (PECS) has revolutionized communication for non-verbal children, particularly those diagnosed with Autism Spectrum Disorder (ASD). In pediatric Applied Behavior Analysis (ABA) therapy, PECS facilitates communication in a visual form, empowering children to express themselves without the need for spoken words. This system has not only improved the way children interact with others but also significantly enhances their ability to learn and function in daily life. In this comprehensive guide, we explore the effectiveness of PECS within pediatric ABA therapy, provided by centers like Chicago ABA Therapy.

What is PECS?

Developed in 1985 by Lori Frost and Andrew S. Bondy, PECS is a unique form of augmentative and alternative communication that uses pictures to teach children how to communicate with others. Unlike other communication methods that require a verbal response, PECS starts with teaching children to exchange a picture of a desired item with a communicative partner. This simple yet effective approach helps to build a foundation of communication for children who find verbal expression challenging.

The Six Phases of PECS

PECS is implemented in six progressive phases, designed to develop from simple exchanges to more complex forms of communication:

  1. Phase 1: How to Communicate – Children learn to exchange single pictures for items or activities they really want.
  2. Phase 2: Distance and Persistence – The practice is expanded to different places and people, requiring the child to be more persistent and generalizing the skill.
  3. Phase 3: Picture Discrimination – Children learn to select from two or more pictures to ask for their favorite things. These choices encourage decision-making.
  4. Phase 4: Sentence Structure – Children learn to construct simple sentences on a detachable sentence strip using an “I want” picture followed by a picture of the item they are requesting.
  5. Phase 5: Answering Questions – Children learn to use PECS to answer the question, “What do you want?”
  6. Phase 6: Commenting – Now able to communicate their desires, children learn to comment in response to questions like “What do you see?” “What do you hear?” or “What is it?”

Benefits of PECS in Pediatric ABA Therapy

The integration of PECS within ABA therapy programs offers several key benefits:

  • Enhances Communication: PECS allows children to initiate communication and express their needs and desires, which can reduce frustrations and behavior issues associated with the inability to communicate.
  • Promotes Independence: By providing a tool for independent communication, PECS empowers children and reduces their dependency on others to interpret their needs.
  • Encourages Social Interaction: PECS helps children interact with their peers, teachers, and family members, which enhances their social skills and integration into different environments.
  • Facilitates Learning: Through visual cues, children can more easily understand and follow classroom instructions and daily routines.

"Chicago ABA Therapy is a boon for special needs kids and parents. They take a play-based, personalized approach and meet the kids where they are. They also go above and beyond - our ABA therapist took time to make sure we as parents understood every aspect of our child's experience, understood how to read his progress reports and generally made us feel a part of his therapy. My child loved all his therapists. Highly recommend the team!"

"We were so happy with our experience with Chicago ABA. We began working with them when our son was almost 4, a few months after his autism diagnosis. It was such an amazing team to work with - everyone was professional, responsive, flexible, and worked so hard for our son to meet his goals, which he did beautifully. We worked together for almost 2 years before he left for kindergarten, and in that time period he met almost all of his goals. We went through several bumps in the road with behavioral difficulties, and the Chicago ABA team did an amazing job helping us problem solve, try new strategies and think of ways to translate those strategies at home. We couldn't recommend them more highly - anyone who works with Chicago ABA will be lucky to have the experience!"
