The Role of Picture Exchange Communication System (PECS)

Introduction to PECS

Understanding PECS Basics

The Picture Exchange Communication System (PECS) is a communication method designed to support individuals with expressive communication limitations. This innovative system helps them understand the mechanics of communication, motivating them to engage and develop structured expressive communication skills through the use of picture symbols that accurately represent activities [1].

PECS was created in the United States in 1985 by Andy Bondy, PhD, and Lori Frost, MS, CCC-SLP. Initially implemented with preschool students diagnosed with autism at the Delaware Autism Program, it has since been adopted worldwide, benefiting thousands of learners of all ages with various cognitive, physical, and communication challenges.

This system makes communication tangible by requiring individuals to physically exchange a picture to express their needs or desires. This process captures the attention of the communicative partner, which can make the act of communicating more effective. However, it can be challenging for some individuals to communicate through pictures and recognize symbolic representations. In these cases, guidance from a trained Speech Language Pathologist (SLP) can be invaluable [4].

PECS is structured into six distinct phases, allowing for a tailored approach to learning and communication based on the individual's abilities. This systematic method assists learners in gradually acquiring communication skills, ultimately leading to more effective self-expression. For further details on the phases involved, readers may explore the section on the six phases of PECS.

The Development of PECS

Origins of the Picture Exchange Communication System

The Picture Exchange Communication System (PECS) was developed in the United States in 1985 by Dr. Andy Bondy and Lori Frost, MS, CCC-SLP. It was part of the Delaware Autism Program and was initially designed for preschool students diagnosed with autism. The system is grounded in the principles of Applied Behaviour Analysis (ABA) and aims to enhance communication for individuals with various cognitive, physical, and communication challenges.

PECS utilizes a structured teaching protocol based on B.F. Skinner's book, Verbal Behavior, which focuses on the importance of behavior and environment in learning communication. The system progresses through six distinct phases, which start with teaching individuals to exchange a single picture representing a desired item or action. As individuals gain proficiency, they learn to use modifiers, answer questions, and make comments, all aimed at fostering functional communication skills [6].

Since its inception, PECS has successfully been implemented globally, benefiting learners of all ages with various needs. By focusing on developing independent communication skills, PECS not only aids communication but also empowers individuals with autism to express their needs and desires more effectively. The success of the system highlights its flexibility and adaptability across different contexts and learner profiles.

Implementing PECS

Strategies for Introducing PECS

Introducing the Picture Exchange Communication System (PECS) can be a transformative experience for individuals with expressive communication limitations. Effective implementation requires thoughtful strategies to ensure successful adoption.

Research supports the effectiveness of the PECS approach. Studies indicate that learners using PECS not only improve their communication skills but may also develop speech or transition to a speech-generating device (SGD). The system requires individuals to physically exchange pictures, which reinforces the act of communication and captures the attention of communicative partners. By carefully implementing these strategies, individuals with autism can thrive using the picture exchange communication system (PECS).

The Six Phases of PECS

Breaking Down the Steps

The Picture Exchange Communication System (PECS) consists of six structured phases that guide individuals in using visual communication effectively. Each phase builds upon the skills learned in the previous ones, promoting functional communication skills.

PhaseDescriptionPhase 1Teaching the Physical Exchange: The initial step involves teaching individuals to give a single picture of a preferred item or action to a "communicative partner." The partner acknowledges the exchange, reinforcing it as a request [6].Phase 2Extending Distances: In this phase, the individual learns to exchange pictures from farther distances, promoting independence and more adaptive communication.Phase 3Discrimination Between Symbols: Individuals are taught to select from multiple pictures to request specific items or actions, enhancing their ability to differentiate between symbols.Phase 4Increasing Utterance Length: This phase encourages individuals to combine pictures into simple sentences, facilitating more complex requests and enhancing expressive language skills.Phase 5Using PECS to Answer Questions: The individual learns to respond to questions using their picture system, thereby building their conversational skills.Phase 6Teaching Commenting: The final phase focuses on enabling individuals to make comments about their environment, experiences, or feelings, fostering deeper interactions and exchanges.

This systematic approach to functional communication is critical not only for individuals with autism but also for others who may benefit from structured communication methods.

By understanding and implementing these phases, individuals can enhance their ability to communicate effectively, reducing frustration and improving social interactions.

Effectiveness of PECS

Research and Results

The effectiveness of the Picture Exchange Communication System (PECS) as a communication strategy for individuals with autism spectrum disorder (ASD) and intellectual and developmental disabilities (IDD) has been supported by various research studies. These studies indicate that PECS can significantly enhance functional communication skills, particularly for those who have limited or no verbal language abilities.

A meta-analysis conducted by Hart and Banda (2010) demonstrated that PECS increased functional communication for nearly all participants involved. The research emphasized that motivating operations within the PECS framework improved the speed at which individuals could acquire skills, especially in the initial phase of the system.

Additionally, a study by Schreibman and Stahmer in 2014 focused on 19 children aged 2.5 years with ASD. The results showed that participants learned an average of 90 spoken words after six months of PECS intervention, which increased to approximately 120 spoken words after nine months. This data illustrates the potential of PECS to foster spoken language development [7].

Research indicates that the primary goal of PECS is to facilitate functional communication, and findings suggest that some learners using this system not only develop clear communication skills, but also transition to using speech-generating devices (SGDs). Over 240 research articles from around the globe further support PECS as an evidence-based practice, indicating its widespread acceptance and effectiveness for individuals with communication challenges.
