Evidence-based Intervention to Help your Child Talk
Research evidence indicates that the Picture Exchange Communication System (PECS) is effective in improving the communication of children with autism (ONTABA, 2017). PECS intervention is built around the key elements of verbal behaviour defined by the founder of Applied Behaviour Analysis, B.F. Skinner.
PECS is an alternative communication system that can be used to replace speech, when necessary, or to enhance spoken language and provide a bridge to more effective communication. For a detailed description visit:
Children naturally first learn to request the things they want. After that, they learn to name objects in their world, respond to instructions and eventually to converse back and forth with others. Motivation is the key to communication, so PECS first teaches children to ask for the things they want.
