Understanding PECS For Autism

Understanding PECS for Autism

Communication can be a significant challenge for individuals with autism, particularly those with expressive communication limitations. The Picture Exchange Communication System (PECS) offers a structured approach to enhance communication and improve social-communicative behaviors in individuals with autism.

Introduction to PECS

The Picture Exchange Communication System (PECS) was developed in the United States in 1985 as part of the Delaware Autism Program. It is based on the principles of Applied Behavior Analysis (ABA) and aims to provide individuals with an alternative means of communication. PECS utilizes a series of picture cards, allowing individuals to initiate communication by exchanging a picture card for a desired item or action.

PECS is designed to motivate individuals with autism to actively participate in communication exchanges. It offers a visual support system that helps individuals understand how communication works and encourages meaningful interactions [2]. Through the use of PECS, individuals can develop structured expressive communication skills, even if they have difficulty with verbal speech.

Effectiveness of PECS

Research has shown positive effects of the Picture Exchange Communication System (PECS), particularly in the early stages of teaching children how to request items. A study using a multiple baseline design found that children with autism who received PECS training displayed increased verbal speech, social-communicative behaviors, and a reduction in problem behaviors [3]. PECS has been found to be effective in improving communication skills and reducing communication limitations in individuals with autism.

It's important to note that while PECS provides an alternative means of communication, it does not hinder the development of speech. Instead, it can enhance communication skills and enable individuals with limited verbal language skills to express their needs, make comments, and answer questions. The use of PECS can be tailored to the individual's needs and abilities, allowing for personalized communication strategies.

Implementing PECS often involves trained professionals, such as Speech Language Pathologists (SLPs), who can guide individuals with autism in effectively utilizing picture communication. Pyramid Educational Consultants is a certified organization that provides training in PECS, and many professionals, including parents and teachers, have been trained in this system. The initial costs for PECS training may vary, but ongoing costs are generally low, making it a cost-effective communication intervention.

In the next sections, we will explore the benefits of PECS, the implementation process, and the specific phases involved in this communication system, providing a comprehensive understanding of how PECS can empower individuals with autism to express themselves effectively.

Benefits of PECS

The Picture Exchange Communication System (PECS) has proven to be an effective communication tool for individuals with autism. Through the use of pictures, PECS helps improve communication skills and reduce problem behaviors.

Communication Improvement

PECS provides individuals with expressive communication limitations a structured way to engage in meaningful exchanges. It helps them understand how communication works and motivates them to communicate with others, even if they struggle with verbal speech [2]. PECS allows individuals to communicate their wants, needs, and thoughts by exchanging pictures with a communication partner.

Research studies have shown that the implementation of PECS leads to significant improvements in communication skills for individuals with autism. In a study conducted with children with autism, it was observed that all participants met the learning criterion for PECS and displayed concomitant increases in verbal speech and social-communicative behaviors [3]. PECS doesn't inhibit speech development but provides an alternative means of communication, which can enhance overall communication skills.

Reduction in Problem Behaviors

PECS has also demonstrated the ability to reduce problem behaviors in individuals with autism. By providing a structured and effective means of communication, PECS helps individuals express their wants and needs, reducing frustration and challenging behaviors that may arise from communication difficulties.

In a case study, a child with autism exhibited a reduction in stereotyped behaviors, such as head turning and hand flapping, after participating in an intervention program involving PECS and traditional behavioral techniques. The child also displayed increased independence in self-help activities and significant enhancement in communication skills.

By enabling individuals with autism to effectively communicate their needs, PECS helps to improve overall behavior and promote a sense of independence and autonomy.

The benefits of PECS extend beyond improving communication skills and reducing problem behaviors. It empowers individuals with autism to express themselves and engage with the world around them. However, it's important to note that the implementation of PECS may require guidance from experienced professionals, such as Speech Language Pathologists (SLPs), to ensure effective use.

Implementing PECS

When it comes to implementing the Picture Exchange Communication System (PECS) for individuals with autism, there are a few key considerations to keep in mind. This section will explore the importance of training professionals and the cost considerations associated with implementing PECS.

Training Professionals

Implementing PECS effectively requires training professionals who will be working with individuals with autism. Proper training ensures that the professionals understand the principles and techniques of PECS, allowing them to effectively support individuals in their communication development.

Training professionals in PECS involves providing them with a comprehensive understanding of the six phases of the system and how to effectively implement each phase. This training equips professionals with the skills to guide individuals through the different stages of PECS, promote communication initiation, and reinforce positive communication behaviors.

By investing in appropriate training, professionals can confidently implement PECS strategies and provide the necessary support for individuals with autism to develop their communication skills. It is important to ensure that professionals receive ongoing training and support to stay up to date with the latest research and best practices in utilizing PECS.

Cost Considerations

Cost is an important factor to consider when implementing PECS. While the initial investment in training professionals and acquiring the necessary materials may be necessary, the long-term benefits of PECS often outweigh the costs.

The cost of PECS can vary depending on factors such as the training program chosen, the number of professionals being trained, and the resources required. It is recommended to research different training options and consider the specific needs of the individuals with autism and the professionals involved.

It is essential to recognize that the cost of implementing PECS should be viewed as an investment in the individuals' communication development and overall well-being. PECS has been recognized as an evidence-based practice with numerous published articles and research papers supporting its positive outcomes and effectiveness.

While there may be initial costs associated with training and resources, the long-term benefits of improved communication and reduced behavioral challenges make it a worthwhile investment.

The Six Phases of PECS

The Picture Exchange Communication System (PECS) is a structured program designed to improve communication skills in individuals with autism spectrum disorders. It consists of six phases that gradually build upon each other, allowing individuals to develop and expand their communication abilities using pictures instead of words.

Physical Exchange Phase

The first phase of PECS is the Physical Exchange Phase. During this phase, individuals are taught to exchange a picture of a desired item with a communication partner in order to obtain that item [4]. The communication partner prompts the individual to hand them the picture card, which is then exchanged for the desired item or activity. This phase focuses on establishing the basic understanding of communication through picture exchange.

Generalization Phase

The Generalization Phase is the next step in the PECS program. In this phase, individuals are encouraged to use their newly acquired communication skills in a variety of settings and with different communication partners. It aims to generalize the use of PECS beyond the initial training environment.

During this phase, individuals are taught to use the picture exchange system with different people, in different locations, and for a variety of purposes. They learn to initiate communication by selecting and exchanging appropriate picture cards to express their wants and needs. This phase helps individuals develop flexibility in their communication skills and apply them in real-life situations.

The Generalization Phase of PECS plays a crucial role in ensuring that individuals can effectively communicate using the picture exchange system across various contexts. It helps them generalize their skills and become independent communicators in a wide range of social interactions.

By progressing through the different phases of PECS, individuals with autism can develop functional communication skills and overcome communication barriers. The systematic approach of PECS provides a structured framework for individuals to acquire and expand their communication abilities, leading to increased independence and improved quality of life.

PECS in Education

In the realm of education, the Picture Exchange Communication System (PECS) plays a vital role in facilitating communication for individuals with autism spectrum disorders. PECS is a modified applied behavior analysis program designed for early nonverbal symbolic communication training. Let's explore two key aspects related to PECS in education: the PECS training program and the age and criteria for implementing PECS.

PECS Training Program

The PECS training program involves different phases that enable individuals to develop their communication skills. Starting from the initial phase of physical exchange, where the individual learns to exchange a picture for a desired item or activity, the program progresses to more advanced stages. These advanced stages focus on teaching the individual to select target pictures, form sentences, and respond to questions. The goal of the PECS training program is to increase independence and effective communication skills.

Age and Criteria for PECS

PECS training is not limited by age. Instead, it focuses on specific criteria such as intentional communication, personal preferences, and the ability to make selections from pictures. As long as individuals meet these criteria, the PECS training program can be offered to them regardless of their age. This flexibility allows for the implementation of PECS in various educational settings and ensures that individuals of different ages can benefit from the program.

Implementing PECS in education involves tailoring the program to suit the developmental and educational needs of each individual. By incorporating PECS into the curriculum, individuals with autism can enhance their communication skills and engage more effectively with their peers and teachers.

When using PECS in an educational setting, it is important for educators and professionals to be aware of the challenges that individuals with autism may face during the use of PECS. These challenges can include lack of cooperation, attention and cooperation difficulties, sensory problems, fluctuations in mood, and drowsiness. By recognizing these challenges, teachers can tailor their instruction accordingly, providing necessary support to individuals with autism.

Overall, the implementation of PECS in education offers a valuable tool for enhancing communication skills and promoting social interaction among individuals with autism in an educational environment. The flexibility of the program allows for its application across different age groups, enabling individuals to develop their communication abilities and achieve greater independence in their academic pursuits.

Challenges and Considerations

Implementing the Picture Exchange Communication System (PECS) for individuals with autism spectrum disorders (ASD) can come with certain challenges and considerations. It's important to address these factors to ensure the effectiveness and success of the program.

Picture Discrimination Ability

While picture discrimination ability is not a prerequisite for PECS training, individuals who possess this skill may progress faster in the initial stages. However, PECS can be beneficial for individuals who are nonverbal, echolalic, have unintelligible speech, or possess a limited set of meaningful words or signs. The program is designed to support the acquisition of functional communication skills for individuals who do not develop sufficient speech to meet their communication needs.

During the PECS training process, individuals learn to use pictures or symbols to communicate their needs and desires. It's essential to consider the individual's ability to discriminate between different pictures and understand their meaning. Some individuals may find it challenging to differentiate between symbols initially, but with consistent training and support, they can develop this skill over time.

Tailoring Instruction for Challenges

Each individual with ASD is unique, and their communication abilities and challenges may vary. When implementing PECS, it is crucial to tailor the instruction to meet the specific needs of the individual. This may involve adjusting the pace of the training, providing additional support, or modifying the materials used.

Education professionals (EPs) who are responsible for delivering PECS instruction in natural environments can be trained to provide effective PECS communication opportunities. Training typically includes a description of the PECS strategy, practice on implementation, and feedback on performance. EPs with minimal to no prior experience using PECS have demonstrated increased quality and quantity of PECS opportunities.

Working closely with a team of professionals, including speech-language pathologists, behavior analysts, and educators, can help ensure that the PECS program is tailored to the individual's specific needs and challenges. Regular assessment and progress monitoring are also essential to make any necessary adjustments to the training program.

By recognizing and addressing the challenges and considerations associated with PECS implementation, individuals with autism can receive the support they need to develop functional communication skills. With patience, consistency, and customized instruction, the PECS program can be a valuable tool in empowering individuals with autism to express themselves effectively.
