Understanding the Picture Exchange Communication System (PECS)

The Picture Exchange Communication System (PECS) is a widely recognized and effective method of communication for individuals with speech and communication challenges, particularly those with Autism Spectrum Disorder (ASD). Developed by Andy Bondy and Lori Frost in the 1980s, PECS is designed to enhance communication skills by using a system of exchanging pictures.

What is the Picture Exchange Communication System (PECS)?

PECS is a form of augmentative and alternative communication (AAC) that aims to provide individuals with a means of expressing their needs, desires, and thoughts. It is a systematic approach that utilizes visual supports to facilitate communication. The system is based on the principle of functional communication, enabling individuals to initiate and sustain interactions with others.

PECS involves the use of picture cards or symbols that represent desired objects, actions, or concepts. These pictures are presented to the individual in a structured manner, allowing them to exchange the picture for the desired item or outcome. This exchange serves as a form of communication and helps individuals develop meaningful connections with others.

How Does PECS Work?

PECS consists of several phases that guide individuals through the process of communication development. These phases are designed to gradually build and expand communication skills. Here are the main phases of the PECS program:

  1. Phase 1: Communicative Intent: In this initial phase, individuals are taught to initiate communication by exchanging a single picture card to request a desired item or action. They learn the basic concept of communication exchange.
  2. Phase 2: Picture Discrimination: Building upon the skills learned in Phase 1, individuals are introduced to a set of pictures or symbols. They learn to select the appropriate picture from a choice of options to make specific requests.
  3. Phase 3: Sentence Structure: In this phase, individuals begin to construct simple sentences using picture cards. They learn to combine pictures to form meaningful requests or comments, such as "I want cookie" or "I see dog."
  4. Phase 4: Responsive and Spontaneous Communication: The final phase focuses on expanding communication skills to include more varied and complex interactions. Individuals are encouraged to initiate communication in different contexts and respond to questions or comments from others.

By following these phases, individuals using PECS gradually develop their communication abilities, moving from requesting specific items to engaging in more interactive and spontaneous conversations.

The Picture Exchange Communication System (PECS) offers a structured and effective approach to communication for individuals with speech and communication challenges. It provides a visual means of expression, fostering independence, social interactions, and increasing overall communication skills.

The Components of PECS

The Picture Exchange Communication System (PECS) is a structured approach to communication that helps individuals with speech and communication challenges express themselves. PECS consists of several distinct phases, each building upon the previous one to promote effective communication. Let's explore the components of PECS:

Phase 1: Communicative Intent

In the first phase of PECS, the focus is on establishing communicative intent. This involves teaching individuals to initiate communication by exchanging a picture of a desired item or activity with a communication partner. The goal is to develop a basic understanding of the cause and effect relationship between communication and obtaining desired outcomes.

During this phase, individuals are encouraged to approach a communication partner, hand them a picture symbol representing what they want, and prompt the partner to respond accordingly. This initial step sets the foundation for the subsequent phases of PECS.

Phase 2: Picture Discrimination

Building upon the skills developed in Phase 1, Phase 2 of PECS involves teaching individuals to discriminate between different picture symbols. The focus is on helping them understand that each picture represents a specific item or action. They learn to select the appropriate picture symbol from an array of options to effectively communicate their needs and wants.

In this phase, individuals are introduced to a variety of picture symbols and engage in activities that require them to choose the correct symbol to request desired items or actions. This helps them develop their visual discrimination skills and expands their ability to communicate using the PECS system.

Phase 3: Sentence Structure

Phase 3 of PECS focuses on introducing sentence structure to enhance communication. Individuals learn to construct simple sentences using a combination of picture symbols and sentence strips. This phase helps them transition from single-word requests to more complex communication by combining symbols to form meaningful sentences.

During this phase, individuals are taught to arrange picture symbols on a sentence strip to create sentences that reflect their specific needs or wants. This expansion of their communication abilities allows for more detailed and accurate expression.

Phase 4: Responsive and Spontaneous Communication

The final phase of PECS emphasizes the development of responsive and spontaneous communication. Individuals are encouraged to use the PECS system not only to make requests but also to respond to questions, initiate conversation, and share information. This phase aims to foster independent and flexible communication skills.

By the end of Phase 4, individuals are expected to use the PECS system fluently, engaging in meaningful interactions with their communication partners. They gain the ability to initiate and respond to a wide range of communication opportunities, promoting social engagement and independence.

The components of PECS work together to provide individuals with a systematic and structured approach to communication. By progressing through each phase, individuals build their communication skills, ultimately enabling them to express their thoughts, needs, and desires more effectively.

Who Can Benefit from PECS?

The Picture Exchange Communication System (PECS) is a communication tool that can benefit various individuals who face challenges in speech and communication. It is particularly helpful for individuals with Autism Spectrum Disorder (ASD) and those with speech and communication difficulties.

Individuals with Autism Spectrum Disorder

PECS is widely used as an effective communication strategy for individuals with Autism Spectrum Disorder. ASD is a developmental disorder that affects communication and social interaction skills. Many individuals with ASD have difficulty using verbal language to express their needs, wants, and ideas.

PECS provides a structured and visual way for individuals with ASD to communicate. By utilizing pictures and a systematic approach, PECS helps individuals with ASD express themselves, make choices, and engage in social interactions. This can greatly improve their quality of life and enhance their ability to connect with others.

Individuals with Speech and Communication Challenges

PECS is not limited to individuals with ASD. It can also benefit individuals who have speech and communication challenges due to various conditions or developmental delays. These individuals may struggle with verbal communication, making it difficult for them to express their thoughts, needs, and desires.

PECS offers an alternative means of communication for individuals with speech and communication challenges. By using visual symbols or pictures, they can effectively communicate their messages and interact with others. This can empower individuals to express themselves, build relationships, and participate more actively in their daily lives.

PECS is a versatile communication tool that can be customized to suit the needs of individuals with different communication abilities. It provides a structured framework for communication and can be adapted to accommodate various skill levels and communication goals.

It is important to note that while PECS can be a valuable tool for individuals with ASD and speech and communication challenges, it is not a replacement for speech therapy or other forms of intervention. Rather, it is a supportive system that complements and enhances existing communication strategies.

By recognizing the potential of PECS and implementing it appropriately, individuals with ASD and speech and communication challenges can benefit from improved communication skills, increased independence, and enhanced social interactions.

The Benefits of PECS

The Picture Exchange Communication System (PECS) offers several benefits for individuals who have difficulty with verbal communication. By utilizing visual supports and a structured approach, PECS can enhance communication, promote independence, and increase social interactions.

Facilitating Communication

One of the primary benefits of PECS is its ability to facilitate communication for individuals who struggle with verbal language. PECS provides a visual means of communication, allowing individuals to express their wants, needs, and thoughts effectively.
