The Benefits of the Picture Exchange Communication System (PECS) for Non-Verbal Communication.

Introducing the Picture Exchange Communication System

In the realm of communication therapies, the Picture Exchange Communication System (PECS) stands out as a transformative approach for individuals with limited or no verbal communication abilities. This method leverages visual aids to create an effective bridge for those who face communication challenges, particularly benefiting children with autism. Originally developed by Lori Frost and Dr. Andrew Bondy in the 1980s, PECS has since established itself as a fundamental tool in enhancing the quality of life for non-verbal individuals by empowering them to express themselves and interact meaningfully with their surroundings.

Understanding PECS: A Communication Milestone

What is the Picture Exchange Communication System (PECS)?

The Picture Exchange Communication System (PECS) is an augmentative and alternative communication (AAC) strategy designed to support individuals, particularly children diagnosed with autism, who have minimal or no verbal communication abilities. This system empowers users by allowing them to communicate their needs and desires through a structured series of picture exchanges.

PECS addresses the necessity for effective communication by involving users in a tangible exchange process, where they hand over pictures to express themselves rather than relying solely on spoken words. This interaction not only fosters social engagement but also significantly decreases behaviors such as tantrums or frustration that can arise when individuals cannot convey their requirements effectively.

Core principles

Core to the methodology of PECS is a six-phase training protocol that gradually increases communication proficiency.

1. Picture Exchange: Users learn to exchange single pictures for desired items.
2. Discrimination: They then learn to discriminate between various pictures.
3. Sentence Structure: Expanding into forming simple sentences that convey requests.
4. Question Responses: Teaching users to respond to questions utilizing pictures.
5. Text Introduction: Incorporating written words alongside pictures.
6. AAC Independence: Eventually using AAC devices independently.

These phases are essential in enhancing both non-verbal and emerging verbal communication skills among users, promoting confidence and independence.

Target population

PECS is a versatile system, effective for individuals across different ages and abilities, including those with Autism Spectrum Disorder, Fetal Alcohol Syndrome, or even older adults who may have experienced communication challenges post-stroke.

Evidence supports that when implemented correctly, PECS can significantly improve users’ quality of life, foster independence, and enhance social interactions. For instance, research indicates that a notable percentage of users report an increase in spontaneous speech and social interactions, underlining PECS' role as a fundamental tool in communication development.
