Exploring Augmentative and Alternative Communication (AAC) Methods

Introduction: Speaking Through Images

Imagine a world where expressing your thoughts or needs feels like an impossible challenge. For many individuals with autism spectrum disorder (ASD) or developmental disabilities, this is a daily reality. The Picture Exchange Communication System (PECS) offers a solution, allowing these individuals to communicate using images. Speaking through images, PECS transforms the way users interact with the world.

PECS was created in the late 1980s by Dr. Andrew Bondy and Lori Frost, specifically for children with autism. This innovative system uses pictures to help users convey their needs, desires, and thoughts effectively.

Phases of PECS: Speaking Through Images

PECS is based on the idea of exchanging pictures to communicate. It starts with teaching the user to give a picture of a desired item to a communication partner. This simple exchange is the building block for more complex communication skills. Over time, users learn to form sentences, answer questions, and make comments using pictures.

The system is divided into six phases, each one building on the last:

  1. Phase 1: How to Communicate
    • Users learn to give a picture of an item they want to their communication partner. For example, if a child wants a cookie, they hand over a picture of a cookie to get it.
  2. Phase 2: Distance and Persistence
    • Users practice exchanging pictures in different settings and with different people. They also learn to be persistent in their communication.
  3. Phase 3: Picture Discrimination
    • Users learn to choose from two or more pictures to select the item they want. This phase introduces making choices.
  4. Phase 4: Sentence Structure
    • Users start to create simple sentences using a sentence strip. For instance, they might place a picture of a cookie next to a picture that says “I want” to make a request.
  5. Phase 5: Answering Questions
    • Users learn to answer questions like “What do you want?” by using their picture cards to form sentences.
  6. Phase 6: Commenting
    • In the final phase, users learn to make comments about their environment, such as saying “I see a car” using pictures.

Benefits of PECS: Speaking Through Images

The benefits of PECS are many. It promotes independence by allowing users to start communication on their own. It also helps with social interaction, making it easier for users to engage with others. Moreover, PECS can reduce frustration and behavioral issues that come from not being able to communicate.

PECS is very flexible and can be tailored to each individual’s needs. Pictures can represent anything from basic needs like food and drink to more abstract concepts and emotions. This makes PECS useful not only for children but also for adults with communication challenges.

Implementation Tips: Speaking Through Images

Caregivers and educators need to be committed and consistent when using PECS. Regular practice and reinforcement are crucial for progress. Creating a supportive environment where the individual feels encouraged to communicate is also essential.

In conclusion, the Picture Exchange Communication System (PECS) is a powerful tool for enabling communication through images. By breaking down communication barriers, PECS helps individuals with autism and developmental disabilities express themselves and connect with the world around them. Speaking through images, PECS opens new doors for interaction and understanding.
