Teaching Imitation to Children with Developmental Disabilities using Discrete Trial Training in an Inclusive Preschool

This study investigated whether imitation training using discrete trial training is effective for children with developmental disabilities. A multiple probe baseline design across subjects study was conducted in an inclusive preschool. The targeted imitation skills included object imitation, fine motor imitation, and gross motor imitation tasks. The results indicated all participants showed significant improvement in their imitation skills across each domain(Tau-U=-1.000), and these effects were maintained after the training was completed. The results of the study demonstrated that discrete trial training is feasible in an inclusive preschool and effective in improving imitation skills of children with developmental disabilities. These findings are expected to serve as a foundation for future discussions on special education and intervention delivery in inclusive preschool settings.
