Communication is one of the most significant challenges for individuals on the autism spectrum. For many children and adults who are non-verbal or have limited speech, expressing basic needs and desires can lead to extreme frustration. The Picture Exchange Communication System, commonly known as PECS, is a widely recognized tool designed to bridge this gap. By using visual symbols to represent objects and actions, PECS allows individuals to communicate effectively with those around them.
This guide provides a comprehensive overview of how PECS works, the materials you need to get started, and the developmental phases involved in the process. Whether you are a parent, teacher, or caregiver, understanding these visual strategies can significantly enhance the quality of life for those with autism. By following a structured approach, you can help an individual move from simple requests to complex sentence structures.
What is the Picture Exchange Communication System (PECS)?
PECS is an augmentative and alternative communication (AAC) system developed to help individuals with autism and other developmental disabilities. Unlike some communication methods that rely on gestures or sign language, PECS focuses on the physical exchange of a picture for a desired item. This concrete action helps the learner understand the fundamental concept of communication: that their actions can influence others and result in a positive outcome.
The system is unique because it does not require the learner to have pre-existing skills like eye contact or imitation. Instead, it meets the learner where they are and builds skills through a series of six structured phases. Over time, many individuals using PECS also begin to develop spoken language, as the visual cues provide a consistent anchor for verbal sounds.
The Six Phases of PECS Training
Implementing PECS is a gradual process that requires patience and consistency. Each phase builds on the previous one to ensure the learner feels confident in their ability to communicate. Here is a breakdown of the six developmental phases.
Phase 1: How to Communicate
In the first phase, the goal is for the learner to understand the basic act of communication. They learn to pick up a single picture of a highly motivating item, reach toward a communication partner, and place the picture in the partner’s hand. This phase usually requires two adults: one to act as the communication partner and another to physically prompt the learner from behind.
Phase 2: Distance and Persistence
Once the basic exchange is mastered, the learner is taught to generalize the skill. They must learn to travel to their communication binder, remove a picture, and find a person in another part of the room to complete the exchange. This phase teaches the learner to be persistent and to seek out someone when they want to communicate a need.
Phase 3: Picture Discrimination
In this phase, the learner is presented with multiple pictures and must choose the one that represents what they actually want. For example, they might have to choose between a picture of a favorite snack and a picture of a neutral object like a sock. This helps the learner understand that different pictures have different meanings and consequences.
Phase 4: Sentence Structure
Learners begin to construct simple sentences using a “sentence strip.” They might place a picture representing “I want” next to a picture of an apple. They then hand the entire strip to their communication partner. This phase introduces the concept of grammar and helps the learner expand their communicative intent.
Phase 5: Answering Questions
At this stage, the learner is taught to respond to the question, “What do you want?” This moves the communication from purely spontaneous requests to responding to social cues from others. The learner uses their sentence strip to provide the answer, further reinforcing the link between visual symbols and social interaction.
Phase 6: Commenting
The final phase focuses on social communication rather than just requesting items. The learner is taught to comment on the world around them in response to questions like, “What do you see?” or “What do you hear?” They learn to use sentence starters like “I see,” “I hear,” or “I feel,” allowing them to share experiences with others.
Essential Materials for Starting PECS
To implement PECS effectively, you will need a few specific materials. These items help keep the communication process organized and durable for daily use. Most families and classrooms find that having a dedicated kit makes the process much smoother.
- Communication Binder: A sturdy three-ring binder with Velcro strips on the front and inside pages. This serves as the learner’s “voice” and should be portable.
- Visual Icons: Small, laminated cards featuring clear images or symbols. These should represent favorite foods, toys, activities, and common household items.
- Velcro Strips and Dots: You will need plenty of hook-and-loop fasteners to attach the icons to the binder and the sentence strip.
- Sentence Strip: A clear or colored strip of plastic or cardstock with Velcro that can be easily detached from the binder for exchanges.
- Dividers: Tabbed pages inside the binder to categorize icons (e.g., snacks, toys, places) for easier navigation as the learner’s vocabulary grows.
Why Visual Communication Works for Autism
Many individuals with autism are visual learners. They often process images more efficiently than auditory information, which can feel fleeting or overwhelming. Visual communication systems like PECS provide a permanent reference point that does not disappear the moment a word is spoken.
By using pictures, you reduce the cognitive load on the individual. They no longer have to struggle to recall a specific word or motor movement for speech; they simply need to recognize a familiar image. This reduction in stress often leads to a decrease in challenging behaviors, as the individual finally feels understood. Furthermore, visual supports provide a clear structure and routine, which can help manage the anxiety often associated with transitions or changes in the environment.
Tips for Successful Implementation
Starting a new communication system can be a major transition for both the learner and the caregiver. To ensure the best results, keep these practical tips in mind:
- Use High-Motivation Items: Start with items the learner truly loves. The more they want the item, the more motivated they will be to complete the exchange.
- Be Consistent: Ensure that everyone in the learner’s life—parents, teachers, and therapists—uses the same PECS protocol. Consistency is key to mastery.
- Keep the Binder Accessible: The communication binder should always be within reach of the learner. It is their voice, and they should never be “silenced” by having it put away on a high shelf.
- Limit Verbal Prompting: In the early phases, avoid talking too much during the exchange. Let the physical exchange and the visual icon do the talking to prevent the learner from becoming dependent on verbal cues.
- Update Icons Regularly: As the learner’s interests change, update their binder with new pictures. Keeping the content relevant ensures they remain engaged with the system.
Conclusion
The Picture Exchange Communication System is a powerful tool that has helped thousands of individuals with autism find their voice. By breaking communication down into manageable, visual steps, PECS empowers learners to express themselves and interact with the world with confidence. While the process requires dedication and consistent practice, the reward of seeing a child successfully communicate their needs is invaluable.
