The Picture Exchange Communication System
Transcript of The Picture Exchange Communication System
The Picture Exchange Communication System (P.E.C.S) is a communication system designed to teach children with limited communication skills to initiate communication within a social context. P.E.C.S helps develop spontaneous communication among children including nonverbal communicative skills.
• Provides a nonverbal means for communication and functional skills.
• Initiate, and respond to, communication.
• Communicate a request, a thought, or anything that can reasonably be displayed or symbolized on a picture card.
• Make the most of a person’s comparative strengths in visual processing.
PECS does not require complex or expensive materials since it uses picture symbols as the modality. This system can be highly effective in fostering the development of spoken language, improving social skills and reducing problem behaviors. The main focus of P.E.C.S system is giving the children with language difficulties the opportunity to communicate with the world around them. Studies have shown that the use of P.E.C.S can result in increased vocabulary, increased spontaneous communication and even functional verbal speech.
Pros of P.E.C.S
- Teaches a simpler way to communicate.
- Makes it easier for the child to let people know their needs.
- Frustration over not being able to communicate is reduced
Cons of P.E.C.S
-Difficulty interpreting generic symbols.
- Communication is limited to the picture available
-Adults must plan ahead of time for pictures needed
-Must be used in all settings to have the most benefit.
Which disabilities can P.E.C.S Support?
• Those who have various communicative, cognitive, and physical impairments (preschoolers to adults)
Modification- three dimensional and textured symbols instead of pictures
commonly used as a communication aid for children with autism spectrum disorder (ASD)
• Those who lack verbal skills

AT Project: Lesson Outline
General Ed Setting
Subject: Language Arts- Sentence Formation
Lesson Outline continued
In a first grade classroom, during a Language Arts Lesson about Sentence Formation, a student using the PECS Assisstive Technology device would be able to participate in the hands on activity. After the teacher taught the lesson about how to properly form a sentence, she would have each student write a sentence of their own. With a student who uses PECS to communicate, he or she will use the device to properly form his or her sentences. He or she will use numerous pictures to form a sentence. Once he or she has formed the sentence, a peer buddy will write the sentence in words for the student.
PECS consists of 6 phases:
1. How to Communicate:
Students learn to exchange single pictures for items or activities they really want
2. Distance and Persistence:
Using single pictures, students learn to generalize this new skill by using it in different places, with different people and across distances; they are also taught to be more persistent communicators.
3. Picture Discrimination:
Students learn to select from two or more pictures to ask for their favorite things; icons are placed in a communication book (ring binder with strips where pictures are stored and easily removed for communication)
Additional information continued
4. Sentence Structure: Students learn to construct simple sentences on a detachable sentence strip using an “I want” picture followed by a picture of the item being requested.
5. Answering Questions: Students learn to use PECS to answer the question, “What do you want?”
6. Commenting: Students are taught to comment in response to questions such as, “What do you see?”, “What do you hear?” and “What is it?”; they learn to make up sentences starting with “I see–”, “I hear–”, “I feel–”, “It is a–”, etc.
* The learners must understand each stage before moving on to the next phase.*

Cost of P.E.C.S
The cost of PECS varies- depending on what you want.
-A starter kit costs $153
Includes: training manual, large communications book, current pictures for PECS cd
-A training manual costs about $70
-Additional picture packages cost about $60 each
-Large communication book costs $36
-Small book costs $34
-Large sentence strip costs $5
-Small strip costs $4
Overall PECS are very affordable. Of course the more picture sets you want, the more expensive it will become.
This is a great, useful tool for communication that is affordable and easy to access.
