Picture Exchange Communication System (PECS)

Picture Exchange Communication System (PECS)

Picture Exchange Communication System (PECS) is a unique system that enables non-verbal individuals to communicate effectively with others. It is a form of augmentative and alternative communication (AAC) that uses pictures to represent different words, phrases, or concepts.

This system was developed in 1985 by Lori Frost and Andy Bondy, and since then, it has been widely used to help individuals with communication difficulties.

PECS is a highly effective tool for children with autism spectrum disorder (ASD), as well as those with other developmental disabilities that affect communication.

It is designed to teach individuals how to communicate using pictures, which can be used to request items, express needs and wants, initiate social interactions, and much more.

The PECS system consists of six phases, each of which builds on the previous phase:

• Phase 1: The individual is taught to exchange a single picture for a desired item or activity. This helps to teach the concept of communication and the exchange of information.
• Phase 2: The individual is taught to discriminate between pictures and to request items or activities from a range of options.
• Phase 3: The individual is taught to construct simple sentences using two or more picture symbols.
• Phase 4: The individual is taught to answer questions using picture symbols.
• Phase 5: The individual is taught to initiate communication using picture symbols, such as greeting someone or asking a question.
• Phase 6: The individual is taught to use more advanced language skills, such as making comments, asking for clarification, and expressing emotions.

PECS has several advantages over other forms of AAC. One of the main advantages is that it is highly flexible and customizable. The system can be adapted to meet the needs of each individual user, allowing them to communicate in a way that is comfortable and effective for them.

PECS is also a highly visual system, which is particularly helpful for individuals with ASD. Many people with ASD have strong visual processing skills, meaning that they can understand and process visual information more easily than auditory information.

By using pictures to represent language, PECS helps to bridge this gap and enable individuals with ASD to communicate more effectively.

Another advantage of PECS is that it can be used in a variety of settings, including schools, homes, and community settings. This means that individuals can use the system to communicate with a wide range of people, including family members, teachers, and peers.

Benefits of PECS for Individuals with Communication Difficulties

PECS has numerous benefits for individuals with communication difficulties. One of the main advantages is that it provides a means of communication for non-verbal individuals who may otherwise struggle to express their needs or wants.

This can reduce frustration and challenging behaviors, as well as improve quality of life.

In addition, PECS can help to develop language and social skills. By teaching individuals how to communicate using pictures, it can lay the foundation for more advanced language skills in the future.

It can also promote social interaction by enabling individuals to initiate conversations and interact with others.

Another benefit of using PECS is that it can increase independence. As individuals become more proficient in using the system, they may be able to use it to make choices or express their needs without relying on others.

This can improve self-esteem and confidence, as well as reduce reliance on caregivers.

Lastly, the flexibility and adaptability of PECS means that it can be used throughout an individual's life span. It can be modified to meet changing needs or preferences, ensuring that individuals continue to have an effective means of communication throughout their lives.

Implementing PECS in a Classroom Setting

PECS is a highly effective tool for promoting communication and language development in individuals with communication difficulties, especially children with autism spectrum disorder (ASD). One of the best places to implement PECS is in the classroom setting.

To implement PECS successfully in a classroom, it is important to have a structured approach that involves collaboration between teachers, speech and language therapists, parents/caregivers, and other professionals involved in the individual's care.

The following are some key steps for implementing PECS in a classroom setting:

• Assessment: Before implementing PECS, it is important to assess the individual's current communication skills and needs. This can involve using standardized assessments or informal observation to identify areas of strength and weakness.
• Training: Teachers and other professionals working with the individual should receive training on how to use PECS effectively. This may involve attending workshops or training sessions provided by certified trainers or speech and language therapists.
• Creating Picture Cards: Picture cards are an essential component of PECS. Teachers can work with speech and language therapists to create picture cards that are tailored to the individual's needs. These cards should be kept organized and easily accessible for the individual.
• Introducing Phases: The six phases of PECS should be introduced gradually, starting with Phase 1 (exchanging single pictures) before moving on to more complex phases. It is important to ensure that each phase is mastered before moving on to the next one.
• Reinforcement: Reinforcement is critical for success with PECS. Teachers can use positive reinforcement techniques such as praise, stickers, or tokens to encourage individuals to use their picture cards effectively.
• Generalization: Once an individual has mastered the use of picture cards within the classroom setting, it is important to generalize this skill into other settings such as home or community settings.

By following these steps, teachers and other professionals can successfully implement PECS in a classroom setting, providing individuals with communication difficulties with an effective means of communication and promoting language development.

Tips for Creating Effective Picture Symbols for PECS

Creating effective picture symbols is crucial for the success of the PECS system. Here are some tips to keep in mind when creating picture symbols:

• Use clear and simple images: The images used should be clear, simple, and easily recognizable. Avoid using abstract or complicated images that may be difficult to understand.
• Use real-life photos: Whenever possible, use real-life photos instead of drawings or illustrations. Real-life photos can help individuals better understand the meaning behind the image.
• Use high-quality images: Ensure that the images used are of high quality and resolution. Low-quality images can make it difficult to distinguish between different pictures.
• Consider size and shape: The size and shape of the picture symbols should be consistent across all cards. This can help individuals recognize the symbol more easily.
• Include context clues: Including context clues in the picture symbol can help individuals better understand its meaning. For example, adding a picture of a bed with a person sleeping in it can help indicate that the symbol represents "sleep."

By keeping these tips in mind, you can create effective picture symbols that will help individuals with communication difficulties communicate more effectively using the PECS system.

Importance of Individualizing the PECS System

One of the key strengths of the PECS system is its flexibility and adaptability. The system can be tailored to meet the specific needs and preferences of each individual user, making it a highly effective tool for promoting communication and language development.

Individualizing the PECS system involves taking into account factors such as an individual's communication abilities, interests, and goals.

For example, some individuals may respond better to certain types of pictures or symbols than others, while others may have specific interests that can be incorporated into their picture cards.

By individualizing the PECS system, teachers and other professionals can create a more personalized approach to communication that is tailored to each individual's unique needs. This can help to promote engagement and motivation, as well as reduce frustration and challenging behaviors.

Individualization also allows for ongoing modifications to be made as an individual's needs change over time. As an individual becomes more proficient in using picture symbols, for example, they may benefit from more complex or abstract symbols that represent more nuanced concepts.

In short, individualizing the PECS system is critical for success with this form of augmentative and alternative communication.

By creating a customized approach that meets each user's needs and preferences, we can help individuals with communication difficulties communicate more effectively and achieve their full potential.

Challenges When Using PECS and How to Overcome Them

While PECS is a highly effective tool for individuals with communication difficulties, there are some common challenges that may arise when using this system. Here are some of the most common challenges and strategies for overcoming them:

• Difficulty with Discrimination: Some individuals may have difficulty discriminating between different pictures or symbols, making it challenging to use the system effectively.

To overcome this challenge, teachers and other professionals can use visual discrimination training techniques to help individuals learn how to differentiate between pictures more effectively.

• Lack of Motivation: Some individuals may be resistant to using picture symbols or may lack motivation to communicate using this system.

To address this challenge, teachers can incorporate motivating activities or items into communication exchanges, such as offering a preferred toy or snack in exchange for using a picture symbol.

• Limited Vocabulary: In the early phases of PECS, an individual's vocabulary may be limited to basic wants and needs. To expand an individual's vocabulary, teachers can gradually introduce new picture symbols and teach new concepts through interactive activities.
• Inconsistency: Consistency is critical for success with PECS. If different people use different picture cards or if the rules for exchanging cards are not consistent, it can be confusing for the individual.

To promote consistency, it is important to have clear rules and guidelines in place that all caregivers follow.

By being aware of these common challenges and implementing strategies to overcome them, teachers and other professionals can help individuals with communication difficulties successfully use the PECS system to communicate more effectively.

Using Technology to Enhance the Effectiveness of PECS

Technology has revolutionized the way we communicate, and it has also had a significant impact on augmentative and alternative communication systems like PECS. One of the ways technology can enhance the effectiveness of PECS is by using digital picture symbols or apps.

Digital picture symbols are electronic versions of traditional picture symbols that can be accessed using a tablet or other device. These symbols can be highly customizable, allowing individuals to create their own personalized symbol sets that meet their unique needs and preferences.

Apps, such as "Proloquo2Go" and "TouchChat," provide users with a range of communication tools, including visual supports and speech output capabilities.

These apps can be used in conjunction with PECS to enhance its effectiveness, allowing individuals to communicate more effectively in a variety of settings.

Using technology also has the advantage of reducing the need for paper-based materials, which can be cumbersome and difficult to manage. Digital picture symbols and apps are easily transportable, making them ideal for use in multiple settings such as at home, school, or in the community.

However, while technology can enhance the effectiveness of PECS, it should not replace traditional forms of communication entirely.

It is important to strike a balance between traditional methods and technology-based methods to ensure that individuals with communication difficulties have access to a range of communication options that meet their specific needs.

Parental Role in Supporting PECS at Home

Parents and caregivers play a critical role in supporting the use of PECS at home. Here are some ways they can help:

• Reinforcement: As with any new skill, reinforcement is critical for success with PECS. Parents and caregivers can use positive reinforcement techniques such as praise, hugs, or tokens to encourage their child to use their picture cards effectively.
• Consistency: Consistency is key when it comes to using PECS. Parents and caregivers should follow the same rules and guidelines for exchanging picture cards that are used in the classroom setting. This can help to reduce confusion and promote generalization of skills.
• Creating a Communication Book: A communication book is a collection of picture symbols that an individual can use to communicate their wants and needs across different settings.

Parents and caregivers can work with speech and language therapists to create a communication book that is tailored to their child's needs. This book should be easily accessible for the child.

• Incorporating Communication into Daily Routines: Incorporating communication into daily routines can help individuals become more proficient in using picture symbols.

For example, parents can encourage their child to use picture symbols during mealtimes by having them request specific foods or drinks using their cards.

• Encouraging Independence: As individuals become more proficient in using picture symbols, parents should gradually encourage independence by allowing them to initiate conversations or make choices on their own.

By working closely with teachers and other professionals involved in an individual's care, parents and caregivers can support the use of PECS at home, providing individuals with communication difficulties with a consistent approach that promotes language development and independence.

Summary

In conclusion, Picture Exchange Communication System (PECS) is a highly effective tool for individuals with communication difficulties.

Designed to teach individuals how to communicate using pictures, PECS is a flexible and customizable system that can be adapted to meet the needs of each individual user.

By using pictures to represent language, PECS helps to bridge the gap between visual and auditory processing, enabling individuals to communicate more effectively in a wide range of settings.
