What is the Picture Exchange Communication System (PECS) and How Does it Work?

The Picture Exchange Communication System, or PECS, opens doors for individuals who struggle with verbal communication by offering an alternative way to express needs, wants, and thoughts. Developed with a structured approach, PECS has become widely recognized for supporting individuals, particularly those with autism spectrum disorder, in their journey toward more effective interaction.

By using pictures instead of words, PECS empowers users to communicate clearly, bridging the gap between themselves and the people around them.

The Basics of Picture Exchange Communication System (PECS)

Developed by Lori Frost and the Pyramid Educational Consultants, the Picture Exchange Communication System is widely used in autism spectrum disorder and developmental disabilities. It involves the exchange of a picture card to communicate needs and desires effectively. PECS training follows Skinner’s analysis of expressive communication skills, making it a valuable tool in aiding communication for individuals with autism.

What is the Picture Exchange Communication System?

PECS is a comprehensive program deeply rooted in the principles of applied behavior analysis. This unique approach focuses on teaching individuals, especially children, how to use visual cues in the form of pictures to communicate their wants, needs, and thoughts. The origin of this impactful communication tool can be traced back to the collaborative efforts of Lori Frost, a speech-language pathologist, and Andrew Bondy, a behavioral psychologist.

Their combined expertise led to the development of PECS in the late 1980s at the Delaware Autism Program. The effectiveness of this innovative approach quickly gained recognition, leading to its widespread adoption across the globe as a valuable tool to enhance communication skills in children and adults facing communication challenges.

Today, PECS training is accessible through certified professionals associated with Pyramid Educational Consultants, the organization founded by Frost and Bondy. Their dedication to ensuring fidelity to the PECS protocol has ensured the program's effectiveness and global reach.

Key Components of the PECS Framework

The Picture Exchange Communication System, commonly known as PECS, operates on the foundational principles of applied behavior analysis (ABA). This means it emphasizes a structured approach that leverages prompts, reinforcement, and gradual fading of support to teach communication skills systematically. At its heart, PECS is a functional communication system, meaning it prioritizes teaching communication that serves a practical purpose.

The core focus of PECS lies in equipping individuals with a tool to express their needs and desires effectively. Rather than merely labeling objects, PECS empowers individuals to initiate requests and engage in meaningful social interactions. This emphasis on functional communication ensures that individuals learn to use pictures not just as a means of expression but as a gateway to greater independence and social engagement.

By consistently pairing picture exchanges with positive reinforcement, individuals are motivated to continue using the system. This systematic approach fosters the development of communication skills, enabling individuals to navigate their world and build meaningful connections with others more effectively.

Implementing PECS in Different Settings

One of the greatest strengths of PECS lies in its adaptability and effectiveness in various environments, from home life to classroom learning. Parents, caregivers, and educators can seamlessly integrate PECS in their respective settings to promote consistent communication and support for the learner.

This adaptability stems from the visual nature of PECS, making it universally accessible and easily incorporated into diverse routines and activities. Whether it’s requesting a snack at home or participating in a classroom activity, PECS empowers individuals to communicate their needs and wants effectively, fostering independence and active participation in diverse areas of life.

PECS at Home: Strategies for Parents

In the familiar and comforting environment of home, parents can play a pivotal role in implementing PECS to foster communication skills in their children, particularly those with autism spectrum disorder.

During the early stages of PECS, it is crucial to focus on establishing the foundational understanding that exchanging a picture card directly leads to receiving the desired item or action. Parents can create opportunities for communication throughout the day by utilizing preferred items and activities.

Here are some practical strategies:

• Keep picture cards readily available in frequented areas of the home, such as the kitchen, play area, and bedroom.
• Incorporate PECS into daily routines like mealtimes, bath time, and playtime, allowing children to request desired snacks, toys, or activities.
• Encourage siblings and family members to engage in picture exchanges, reinforcing the child's communication efforts.

Remember that while PECS focuses on picture exchange, it can complement and even encourage the development of verbal behavior. By consistently modeling language during exchanges, parents provide valuable opportunities for children to associate spoken words with the picture cards, potentially fostering speech development alongside.

PECS in Educational Settings: A Guide for Teachers

Classrooms present a dynamic setting for implementing PECS, offering numerous opportunities for children with developmental disabilities and communication difficulties to engage in meaningful interactions with peers and teachers. Collaboration between teachers, teacher assistants and speech pathologists is key to ensuring consistent and effective use of PECS throughout the school day.

To create a communication-rich environment:

• Display PECS communication books prominently, making it easy for students to access and use them across different areas of the classroom.
• Incorporate PECS into lessons and activities, allowing students to request desired materials, make choices, or answer questions using their picture cards.
• Encourage peer interactions using PECS, fostering communication and social skills among students.

By integrating PECS into the fabric of the school day, teachers empower students with communication difficulties to become active participants in their learning journey. Providing ample opportunities for meaningful communication allows these students to express their needs, share their thoughts, and engage in a fulfilling educational experience.

The Phases of PECS: A Detailed Overview

The Picture Exchange Communication System follows a well-defined, six-phase approach carefully crafted to introduce concepts gradually, ensuring learners solidify their understanding and skills at each stage before progressing. This structured approach is crucial to the program’s efficacy, fostering long-term successful communication for individuals using PECS.

Below is a table outlining the six phases of PECS:

Understanding Phase I to III: From Initiation to Picture Discrimination

The initial phases of PECS focus on laying a strong foundation for communication, starting with the fundamental understanding that exchanging a picture card leads to obtaining a desired object or action. This concept is introduced in Phase I, where learners are taught to pick up a picture of a desired object and exchange it with a communication partner.

Phase II builds upon this foundation by incorporating distance and persistence. Learners are encouraged to travel to their communication partners and initiate communication spontaneously, fostering independence and initiative. This phase highlights the practical application of PECS, moving beyond structured settings to more natural environments where learners are motivated to communicate their needs.

As learners advance to Phase III, the focus shifts to picture discrimination. Presented with an array of picture cards, learners learn to identify and select the specific card that represents their desired object or action. This phase is crucial for expanding learners' vocabulary and enhancing their ability to make clear and specific requests, paving the way for more complex communication in later phases.

Mastering Phase IV to VI: Sentence Structure and Responding to Questions

As learners progress through the PECS program, they begin to master more complex communication skills. In Phase IV, learners transition from single-picture exchanges to constructing simple sentences. This is usually achieved by introducing a sentence strip featuring the phrase “I want” along with the picture card representing the desired item.

Phase V encourages learners to use their newly acquired sentence-building skills to answer questions. The ability to respond to "What do you want?" demonstrates a new level of communicative competency, highlighting learners' understanding of social interactions and their ability to engage in back-and-forth communication.

Phase VI marks a significant step towards more spontaneous and versatile communication. Learners begin using their PECS communication book to comment on aspects of their environment and answer a wider range of questions. This phase underscores the transformative power of PECS, evolving from a system purely focused on requests to one that empowers individuals to express their thoughts, observations, and feelings.

Conclusion

The Picture Exchange Communication System (PECS) offers a structured and effective way for individuals with communication difficulties to express their needs, desires, and thoughts. By guiding users through six progressive phases—from single-picture exchanges to forming sentences and commenting—PECS provides a clear path to developing essential communication skills. This system adapts well to both home and school environments, enabling children and adults alike to strengthen their independence and social interactions through visual communication.
