Picture Exchange Communication System (PECS)
The Picture Exchange Communication System®, or PECS®, allows people with little or no communication abilities to communicate using pictures. People using PECS are taught to approach another person and give them a picture of a desired item in exchange for that item. By doing so, the person is able to initiate communication. A child or adult with autism can use PECS to communicate a request, a thought, or anything that can reasonably be displayed or symbolized on a picture card. PECS works well in the home or in the classroom.
How PECS was developed
PECS was developed in 1984 by Lori Frost, MS, CCC/SLP and Dr. Andrew Bondy. It was first used at the Delaware Autistic Program. The goal of (PECS) is to teach children with autism a fast, self-initiating, functional communication system. PECS begins with the exchange of simple icons but rapidly builds "sentence" structure.
At one time many people opposed the use of PECS and sign language to teach children with autism to communicate. They argued that these methods would hurt the development of spoken language. However, several studies have shown PECS actually helps people develop verbal language.
Studies have also shown that PECS can decrease tantrums and odd behaviors. For example, an individual may cry because they are thirsty. However, a parent or teacher may not understand why they are crying and as a result their needs will remain unmet. However, if an individual has access to communication pictures they can quickly communicate their need.
