The study investigated the influence of a response delay requirement on the discrimination performance of three autistic adolescents. Results showed that the response delay condition produced higher levels of correct responding than the no reponse delay condition. Teachers rated the response delay procedure practical and effective in a classroom…

Results indicated both procedures were effective…
