Paper Summary:
This paper analyzes two studies that deal with augmentative and alternative communication systems that can assist language development in autistic children. It first reviews "Effects on Communicative Requesting and Speech Development of the Picture Exchange Communication System in Children With Characteristics of Autism," by Jennifer Ganz and Richard Simpson. It then looks at "Effects of a Computer-Based Intervention Program on the Communicative Functions of Children with Autism," by Orit Hetzroni and Juman Tannous.
From the Paper:
"Subjects were taught to present a picture of the desired object and later to create picture sentences by placing strings of pictures on a Velcro strip. At first teachers presented students with the pictures, but the goal was for subjects to independently locate the desired items and string them to form sentences. Pictoral sentences were then to be accompanied by the appropriate verbalization. Each subject had his/her own book of pictures, which were expanded to include photographs of desired objects and sentence starters such as "I want" over time. In this way gradually more complex verbalization could be required. While the beginning pictures dealt primarily with objects themselves, gradually comments on qualities of an object or action as well as objections could also be verbalized. Sessions were videotaped, and independently and holistically scored by observers who agreed when a subject met the specified criteria for non-verbal and then verbal communication."
