Picture Exchange Communication System (PECS)

What is the Picture Exchange Communication System?
The Picture Exchange Communication System (PECS) is a way for autistic people to communicate without relying on speech. To communicate, people use cards with pictures, symbols, words or photographs to ask for things, comment on things or answer questions.

Who is the Picture Exchange Communication System for?
Any autistic person can use the Picture Exchange Communication System (PECS). There’s no age limit, but most research has focused on children. Some children might use PECS for a short time while their speech is developing. Others might use it for longer. Anyone who has difficulties with spoken language can use this therapy. This includes people with developmental delay and traumatic brain injury, as well as autistic people.

Does the Picture Exchange Communication System help autistic children?
Research has shown positive effects from the Picture Exchange Communication System (PECS), particularly for the early stages of PECS, which teach children how to ask for things.

More high-quality studies are needed to investigate the effects of using PECS for more complex communications and to work out which children respond best to PECS. Research also shows that PECS doesn’t stop children from developing speech.

What is the Picture Exchange Communication System used for?
The Picture Exchange Communication System (PECS) gives people without spoken language or with limited spoken language skills an alternative way to communicate. PECS can also increase people’s communication skills. For example, autistic people can learn to use the cards to ask for things, make comments and answer questions.

Where does the Picture Exchange Communication System come from?
The Picture Exchange Communication System (PECS) was developed in the United States in 1985, as part of the Delaware Autism Program. It’s based on the principles of Applied Behaviour Analysis (ABA).

What is the idea behind the Picture Exchange Communication System?
The Picture Exchange Communication System (PECS) is based on the idea that learning happens because of the consequences of a particular behaviour and the events that lead up to it. If a behaviour leads to something that people want, the behaviour will keep happening. If the behaviour doesn’t result in what people want, it’s unlikely to happen again.

In PECS, when children use the picture cards, they’re rewarded with the objects or action they’ve asked for. Supporters of PECS say that this reinforces children’s behaviour. In turn, it increases the likelihood that children will keep using the cards for communicating needs and wants.

What does the Picture Exchange Communication System involve?
Because it’s a method of communication, the Picture Exchange Communication System (PECS) is taught and used on a daily basis.

To start with, the PECS trainer (who might be a teacher or parent) focuses on a child’s favourite foods, toys or other everyday items. The trainer teaches the child to exchange pictures of these items for the actual items.

Later on, the child can use the cards to ask for things, to ask and answer questions, or to do more advanced tasks like making comments. The child moves from exchanging single cards to learning to build short sentences using several cards at a time.

It’s important that parents, teachers and others know how to use PECS properly. Parents and teachers can learn how to use PECS at workshops. Some families learn how to use PECS in speech pathology sessions. Speech pathologists or teachers who have been trained in PECS might also run PECS workshops at schools.

Who practises the Picture Exchange Communication System?
Many speech pathologists, occupational therapists, psychologists, physiotherapists, social workers, parents and teachers have been trained in the Picture Exchange Communication System (PECS). When you’re making an appointment with a new professional, you can ask whether the professional has experience with PECS.

Where can you find a PECS practitioner?
