Abstract
Echolalia can negatively impact multiple skill areas in children diagnosed with autism spectrum disorder (ASD), including skills related to academic and social performance. The purpose of this study was to employ a multiple probe across participants design to evaluate the effects of tact training on delayed echolalia in three children in China diagnosed with ASD. The results of this study indicated that tact training was effective in decreasing echolalia and increasing appropriate tacts for all three children. The effects were maintained 7 weeks following the completion of training.
