Many studies have researched time delay procedures and generalization but there is little existing literature as to using the computer as a communication device with autistic children. The purpose of this study was to show how time delay procedures could increase spontaneous communication in a autistic child on a computer. The subject for this study is an eleven year old autistic male. His speech has been labeled dysparxic, and he has Tourette's Syndrome. A multiple probe design was used to collect the data. Descriptive statistics and point-by-point method (number of immediate responses divided by number of immediate responses plus modeled responses multiplied by 100 ) were used to calculate the response reliability estimates. The results showed between 58% and 66% average response at follow up for each of the responses ("please", "thank you", and "you're welcome").
