LAHORE - The Alumni Society of the Government College University Lahore Clinical Psychology Department has organised a training workshop on Picture Exchange Communication System (PECS). It is a highly effective method of non-verbal communication with Autistic children who have delays in speech development. The clinical psychologists and professionals from all over Punjab attended the workshop. Addressing the participants, resource person Sajjad Ahmad said that PECS uses pictures instead of words to help children communicate and has proved to be very useful in clinics and schools. He said a child can be trained in PECS by parent, caregiver or therapist who has learned about the method. In the early phases of PECS training, the child chooses a picture of a desired food and receives the food in exchange for the picture. Getting the food is the positive reinforcement for using the picture to communicate, he further said.
