For children with autism, communication can be challenging. The Picture Exchange Communication System (PECS) is a tool that helps children express their wants and needs. It is a type of augmentative and alternative communication (AAC) that is based on applied behavior analysis (ABA).
PECS allows children to use pictures instead of words. It is especially helpful for children who struggle with verbal communication. This system gives them a way to express themselves and interact with others.
How Does PECS Work?
PECS teaches communication in a step-by-step process. Children start by learning to exchange a picture of something they want with another person. Over time, they learn to use multiple pictures to form sentences. Eventually, some children may begin to use spoken words as well.
The process includes six phases:
- Basic Picture Exchange – The child hands a picture of a desired item to a communication partner.
- Distance and Persistence – The child learns to exchange pictures from different locations.
- Picture Discrimination – The child chooses from two or more pictures to request an item.
- Sentence Structure – The child forms simple sentences using a sentence strip (e.g., “I want cookie”).
- Answering Questions – The child learns to answer questions like “What do you want?”
- Commenting and Expanding – The child begins to use pictures to make comments about the world around them.
How Is PECS Beneficial?
PECS provides many benefits for children with autism, including:
- Encourages Communication – It gives children a reliable way to express their needs.
- Reduces Frustration – When children can communicate, they may have fewer meltdowns.
- Supports Social Interaction – PECS helps children engage with others in a meaningful way.
- May Lead to Speech Development – Some children who start with PECS later begin to use verbal speech.
- Builds Independence – Children learn how to communicate their needs without relying on others to guess what they want.
The Connection Between PECS and ABA Therapy
PECS is based on the principles of ABA therapy. ABA focuses on teaching new skills through positive reinforcement. In ABA, therapists help children learn to use PECS by rewarding their communication efforts. Over time, children become more confident in using pictures to express themselves.
PECS is often used in ABA therapy sessions to build communication skills. Therapists use structured teaching and reinforcement to help children progress through the six phases. Because ABA is individualized, PECS can be tailored to each child’s needs.
