Introduction to Picture Exchange Communication System (PECS)

In the realm of communication strategies, the Picture Exchange Communication System (PECS) stands out as a powerful tool for individuals who face challenges in verbal communication. PECS is a systematic approach that aims to teach functional communication skills to those who lack the ability to speak. By utilizing visual symbols, PECS facilitates communication and empowers individuals to express their wants, needs, and ideas effectively.

What is PECS?

The Picture Exchange Communication System (PECS) is a modified applied behavior analysis program developed for early nonverbal symbolic communication training. While PECS does not directly teach speech, it encourages speech indirectly, often leading to children using speech while participating in the program. The program was originally created at the Delaware Autistic Program and is implemented within the natural settings of classrooms and homes.

PECS operates on the principle that individuals with complex communication needs can improve their communication skills by using visual symbols to convey their messages. The system provides a structured framework for communication development, focusing on the exchange of pictures as a means of communication.

Importance of Picture Communication

The importance of picture communication cannot be overstated, particularly for individuals who struggle with verbal communication. Pictures offer a visual representation of language, allowing individuals to express themselves more effectively and understand the communication of others.

By utilizing pictures, PECS provides a means for individuals to initiate and engage in communication. This can be especially beneficial for individuals with autism spectrum disorder and other developmental disabilities, who may face challenges in understanding and using speech effectively. With PECS, individuals can overcome these barriers and actively participate in social interactions.

Research has shown that the use of visual symbols, such as those employed in PECS, can enhance communication skills and promote independence in individuals with complex communication needs. The systematic approach of PECS ensures that individuals progress through different phases of communication development, gradually expanding their abilities and improving their overall communication skills.

In summary, the Picture Exchange Communication System (PECS) provides a structured and effective approach to communication for individuals with complex communication needs. By utilizing visual symbols and progressing through different phases, PECS empowers individuals to communicate their wants, needs, and ideas, ultimately promoting social interaction and independence.

The Phases of PECS

The Picture Exchange Communication System (PECS) follows a structured approach that consists of six phases to gradually shape communication skills, enabling individuals to effectively convey their wants, needs, and thoughts. Let's explore each phase of PECS in detail:

Phase 1: Picture Exchange

In the initial phase of PECS, the focus is on teaching individuals to exchange a single picture for an item or activity they desire. This phase emphasizes the basic concept of communication through picture exchange. Individuals are encouraged to approach a communication partner, hand them a picture, and receive the desired item or activity in return. This simple exchange serves as the foundation for further communication development.

Phase 2: Distance and Persistence

Building upon the skills learned in Phase 1, Phase 2 of PECS introduces the concepts of distance and persistence. Individuals are taught to use the PECS communication book or system to request items or activities from a distance, rather than relying on immediate proximity. This phase helps individuals understand that communication can happen even when they are not physically close to their communication partner.

Phase 3: Picture Discrimination

Phase 3 focuses on developing the ability to discriminate between different pictures and select the most appropriate one to convey their message. Individuals learn to choose from an array of pictures to represent their desired item or activity. This phase enhances their visual discrimination skills and promotes the understanding that different pictures correspond to different requests.

Phase 4: Sentence Structure

Moving forward, Phase 4 introduces sentence structure into the communication system. Individuals learn to construct simple sentences by combining picture cards representing different words or concepts. This phase allows for more expressive and flexible communication, enabling individuals to form more complex requests.

Phase 5: Responding to Questions

Phase 5 of PECS focuses on teaching individuals to respond to questions using the picture communication system. They learn to select appropriate pictures to answer questions posed by their communication partners. This phase enhances their receptive language skills and encourages active participation in conversations.

Phase 6: Commenting

The final phase of PECS aims to develop the ability to make comments and share information using the picture communication system. Individuals learn to spontaneously express their thoughts, share experiences, and engage in social interactions through comments. This phase promotes independence and empowers individuals to initiate and sustain conversations.

By progressing through these six phases, individuals using PECS gradually develop their communication skills, starting from basic picture exchange to more advanced levels of communication like constructing sentences, responding to questions, and making comments. Each phase builds upon the previous one, providing a structured pathway for effective communication development.

Implementing PECS

To effectively implement the Picture Exchange Communication System (PECS), several key considerations should be taken into account. These include training and guidance, selecting appropriate picture symbols, and motivating and engaging learners.

Training and Guidance

Implementing PECS requires guidance from experienced professionals, such as Speech Language Pathologists (SLPs), who specialize in communication strategies for individuals with difficulties in picture communication. Guidance from these professionals can be crucial in understanding and implementing the principles of PECS effectively. Trained professionals can provide valuable insights into teaching techniques, troubleshooting challenges, and ensuring consistency in the use of PECS.

Selecting Picture Symbols

Choosing appropriate picture symbols is essential in making communicative messages understandable for individuals using picture communication systems like PECS. The selection of picture representation type and size should be based on individual needs, considering factors such as cognitive abilities and personal preferences. Picture symbols can include photographs, colored or black and white line drawings, or tangible symbols. There is no restriction on the choice of symbols, although options such as Mayer-Johnson Picture Communication Symbols (PCS) can be utilized.

Motivating and Engaging Learners

Teaching independent expressive communication to individuals with difficulties in this area requires finding ways to motivate and engage them in the learning process. Using a structured and fun approach can help students develop communication skills effectively. Instructional materials can also be beneficial, especially when used by trained team members who understand the student's abilities and goals. It is important to consider the individual needs and goals of each learner when implementing PECS.

By providing proper training and guidance, selecting appropriate picture symbols, and employing motivational strategies, the implementation of PECS can be optimized. Trained professionals and caregivers play a crucial role in ensuring the effective use of PECS and supporting the communication development of individuals who benefit from this system.

Exploring Picture Exchange Communication System (PECS)

The Picture Exchange Communication System (PECS) is a systematic approach designed to teach communication skills to individuals with complex communication needs, particularly those with little or no speech. Developed by Lori Frost and Andy Bondy in 1985, PECS serves as an initial learning strategy to help individuals quickly acquire a functional means of communication [3].

PECS consists of six distinct phases, each building upon the previous one, with the ultimate goal of fostering independent and effective communication. Let's explore these phases in detail:

Phase 1: Picture Exchange

Phase 1 focuses on teaching the individual to initiate communication by exchanging a single picture symbol for an item or activity they desire. At this stage, the individual learns to approach a communication partner, hand them a picture, and receive the desired item or activity in return.

Phase 2: Distance and Persistence

In Phase 2, the individual learns to generalize their communication skills by using the picture symbols in different locations and with different communication partners. They also learn to persist in their communication attempts, ensuring that their message is understood and their needs are met.

Phase 3: Picture Discrimination

During Phase 3, the individual expands their vocabulary by learning to discriminate between different picture symbols. They acquire the ability to select specific symbols from an array of options, enabling them to communicate more specific wants and needs.

Phase 4: Sentence Structure

Phase 4 involves introducing sentence structure into the communication system. The individual learns to combine multiple picture symbols to form simple sentences, such as "I want ____" or "I see ____." This phase enhances their ability to express more complex thoughts and desires.

Phase 5: Responding to Questions

In Phase 5, the focus shifts to teaching the individual how to respond to questions using the PECS system. They learn to use appropriate picture symbols to answer questions such as "What do you want?" or "What do you see?" This phase encourages active participation in conversational exchanges.

Phase 6: Commenting

The final phase of PECS centers around teaching the individual how to make comments using picture symbols. They learn to share information, express opinions, and engage in social interactions by using the PECS system to comment on their environment or experiences.

Implementing PECS requires training, guidance, and consistency. It involves selecting appropriate picture symbols that represent the individual's wants, needs, and interests. Motivating and engaging learners is crucial to ensure their active participation in the communication process.

The benefits of utilizing PECS are numerous. It enhances communication skills by providing individuals with a functional means of expression, promoting independence and reducing frustration. PECS also facilitates social interaction, allowing individuals to engage in meaningful interactions with their peers and caregivers.

PECS has proven to be particularly effective for individuals with Autism Spectrum Disorder (ASD), as well as those with speech, language, and communication needs. Research and evidence support the use of PECS in improving communication outcomes for individuals across various settings.
