PECS in Autism: Exploring its Benefits

Overview of PECS

In the world of autism, various support systems and programs have been developed to aid autistic individuals, especially those with communication difficulties. One of these systems is the Picture Exchange Communication System (PECS), which has shown great potential in empowering non-verbal or minimally verbal individuals.

Definition and Purpose of PECS

PECS, or Picture Exchange Communication System, is a type of augmentative and alternative communication (AAC) often used with children with autism who have little or no speech. This system is based on the use of pictures rather than words, making it easier for children to grasp the concept of communication [1].

The purpose of PECS is to teach intentional, functional communication and enable users to express their wants and needs. This system is specifically tailored to assist children with autism who have difficulty initiating communication. By using pictures, it reduces the intimidation of speaking for them initially, making it a valuable resource for children and young people with Autism Spectrum Conditions and other communication difficulties [2].

The Six Phases of PECS

The PECS intervention consists of six phases and starts with teaching the child to exchange a single picture for an item or activity that the child wants. This method progresses to constructing sentences by selecting and exchanging a series of pictures [1].

Here's a simple breakdown of the six phases:

Phase 1: The child learns to exchange a single picture for a desired item.
Phase 2: The child learns to generalize this skill in different settings, with different people and with different pictures.
Phase 3: The child learns to select from two or more pictures to ask for their favorite things.
Phase 4: The child learns to put together sentences on a sentence strip, starting with "I want" followed by the picture of their desired item.
Phase 5: The child learns to answer the question, "What do you want?"
Phase 6: The child learns to comment on things in their environment, using phrases such as "I see" or "I hear".

By following these six phases, PECS aims to improve the communication skills of children with autism, empowering them to express their thoughts, needs, and desires more effectively.

Implementing PECS in Autism

Incorporating the Picture Exchange Communication System (PECS) into the lives of individuals with autism can be highly beneficial. This section seeks to explore who can utilize PECS and the appropriate situations for its implementation.

Who Can Use PECS

PECS has been designed to aid individuals who have limited or no verbal communication skills. It's frequently employed with both children and adults diagnosed with Autism Spectrum Conditions. The system provides a structured format for consistent use by various individuals in different environments, ensuring clear communication regardless of the setting.

In terms of who can facilitate the implementation of PECS, it's a wide array. Parents, caregivers, teachers, speech pathologists, and other professionals can all participate in utilizing PECS with an individual with autism. Consistent and structured practice is crucial to support the person's learning and progress with the PECS system.

Where and When to Use PECS

PECS boasts a level of flexibility that makes it suitable for multiple settings. It can be employed at home, school, clinics, and even in community environments. This adaptability ensures that the individual needs of the child with autism can be met, regardless of their location.

Moreover, PECS should be used at every given opportunity to become the user's voice. This means that access to the system should be available at all times, anywhere. Portable PECS books facilitate this, allowing for use in various settings, including during community activities.

In essence, implementing PECS in autism requires commitment from a wide group of people in the individual's life and can be utilized in a variety of settings. This flexible communication tool can greatly enhance an individual's ability to express their needs and desires, providing a significant boost to their independence.

Impact of PECS on Communication

The Picture Exchange Communication System (PECS) brings a significant impact on the communication abilities of individuals with autism. This system enables the improvement of functional communication skills and fosters increased independence.

Functional Communication Skills

PECS has been shown to effectively improve functional communication in children with autism, including initiating requests, exchanging objects, and making comments. It serves as a valuable resource for children and young people with Autism Spectrum Conditions and other communication difficulties, aiming to teach intentional, functional communication and enable users to communicate their wants and needs [2].

The system enhances communication skills by providing individuals with autism a means to communicate their needs, wants, and thoughts effectively using visual symbols. PECS allows individuals to start with simple requests and gradually progress to more complex sentences and conversations. This step-by-step approach promotes language development and expands communication skills over time.

Increasing Independence with PECS

PECS not only empowers individuals with autism in their communication skills but also promotes independence and self-advocacy. It allows them to make choices, request assistance, and participate in decision-making. This independence can be fostered in various settings, such as at home, school, and in community settings, facilitating effective communication and fostering independence.

Teaching independent expressive communication to students with communication difficulties can be challenging. However, by introducing and teaching picture communication in a fun and stimulating manner, the process can motivate students to engage and acquire structured expressive communication skills.

In conclusion, the impact of PECS on communication skills and independence for individuals with autism is profound. By providing an accessible and effective way for these individuals to express their needs, wants, and thoughts, PECS can help them lead more fulfilling and independent lives.

Combining PECS and Traditional Techniques

In the realm of autism intervention strategies, combining the Picture Exchange Communication System (PECS) with traditional techniques can offer an effective approach to manage communication deficits and improve targeted behaviors.

Role of Differential Reinforcement

One of the traditional techniques often combined with PECS is Differential Reinforcement of Alternative Behavior (DRA). DRA is a method used to reinforce adaptive behaviors and address maladaptive responding in individuals with autism. In the context of PECS, DRA can be used to encourage the use of picture cards for communication and discourage non-communicative behaviors.

Moreover, this combination of PECS with DRA has shown significant improvements in targeted behaviors, including a decrease in stereotyped behaviors like head turning and hand flapping. It has also led to an increase in independence in self-help activities and enhancement in communication skills in children with autism. Crucially, these gains have been maintained even at the three-month follow-up after the intervention.

Strategies for Managing Communication Deficits

In addition to DRA, other traditional techniques such as reprimand and task direction are often combined with PECS to manage communication deficits in autistic individuals. Here, the role of reprimand is to provide feedback for inappropriate behaviors, while task direction involves guiding the individual through tasks to encourage adaptive behaviors.

As per research data, the combination of PECS with these traditional techniques has resulted in significant improvements in communication skills and a decrease in maladaptive behaviors in children with autism [6].

By blending PECS with such traditional techniques, professionals can customize interventions to the individual needs of each child. This tailored approach can potentially lead to significant improvements in communication skills and a decrease in maladaptive behaviors, fostering better outcomes in the long run for children with autism.

Challenges and Solutions in PECS

While the Picture Exchange Communication System (PECS) can be a powerful tool in facilitating communication for individuals with autism, it also presents some challenges. The two main areas of focus include understanding symbolic representations and tailoring PECS to individual needs.

Understanding Symbolic Representations

One of the primary challenges in using PECS is the process of understanding symbolic representations. This involves the recognition and interpretation of pictures as stand-ins for real-world objects or actions. For some individuals, especially those on the autism spectrum, this can be a complex cognitive task.

To address this challenge, it can be beneficial to use matching picture symbols that precisely represent activities or objects. This can make the communicative messages more understandable for individuals with communication challenges. For example, a picture of a specific toy can be used to represent that toy, rather than using a generic picture of a toy.

Additionally, seeking guidance from an experienced Speech Language Pathologist (SLP) can be valuable for those implementing picture communication techniques. An SLP can provide strategies and tips for teaching symbolic understanding, making the process more manageable and effective.

Tailoring PECS to Individual Needs

PECS, like any other educational approach, should be tailored to the individual needs of the student. Prior to using instructional materials or implementing picture communication strategies, it is important to consider the abilities and goals of the student with autism. This ensures the effectiveness of the learning materials and helps to better align the strategy with the individual's developmental and communicative needs [5].

The tailoring process might involve choosing appropriate symbols, adjusting the pace of instruction, or modifying the learning environment to better suit the student. This personalized approach can help to maximize the benefits of PECS and make the communication process more accessible and meaningful for the individual with autism.

While these challenges can make the implementation of PECS seem daunting, the potential benefits for communication and independence make it a worthwhile endeavor. With appropriate support and individualization, PECS can be a powerful tool in empowering individuals with autism to express their needs, desires, and thoughts.

Success Stories and Research Findings

A variety of research findings and individual success stories underline the effectiveness of PECS (Picture Exchange Communication System) in enhancing the communication skills and minimizing behavioral issues in individuals with autism. This section will delve into some of these studies and their outcomes.

Case Studies on PECS Efficacy

A significant study conducted with a seven-year-old male child diagnosed with childhood autism showed remarkable improvements in target behaviors related to repeated head turning, hand flapping, and poor communication skills. After thirty-two sessions of interventions spread over three months, using PECS combined with traditional behavioral techniques, there was a significant improvement of around 60% in target behaviors.

The combination of PECS with traditional techniques like Differential Reinforcement of Alternate behavior (DRA), reprimand, and task direction resulted in significant improvements in targeted behaviors. These included a decrease in stereotyped behaviors like head turning and hand flapping, an increase in independence in self-help activities, and enhancement in communication skills in children with autism. The gains were maintained even at the three-month follow-up after the intervention [6].

Long-term Benefits of PECS

PECS has been shown to improve functional communication, including initiating requests, exchanging objects, and making comments, in children with autism.

Peer-mediated interventions, where typically developing peers are taught strategies to initiate and maintain social interactions with children with autism, have been found to improve social communication and play skills in children with autism [3].

Moreover, teaching peers to be responsive communication partners using PECS can increase rates of functional communication and engagement in dyadic play for nonverbal or minimally verbal preschoolers with autism.

These findings demonstrate the long-term benefits of PECS, making it a valuable tool in autism interventions. By using PECS, individuals with autism can improve their functional communication skills, reduce unwanted behaviors, and increase their engagement and independence, thereby enhancing their overall quality of life.
