Adult picture exchange
PECS is also is used to teach the child to make a choice.The different functions of communication are then gradually expanded beyond requesting (see below).
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 was developed in 1984 by Lori Frost, MS, CCC/SLP and Dr. It was first used at the Delaware Autistic Program.
While speech pathologists might be the primary PECS program coordinator for a specific child, it is helpful to have others also attend the two-day trainings since they too will play an important role.
These others could include parents, the classroom teacher, and classroom assistants.
The six phases are described below to provide a general understanding of the approach: The Picture Exchange Communication System provides children with direct training in how to initiate communication.
This training is important for those children who would prefer to go and get what they need or want instead of requesting it from another person.
