This study used an alternating-treatment design to compare the efficacy of discrete trial training (DTT) with fluency training (FT) for the acquisition, stimulus generalization, and retention of noun labels in children with autism. Four elementary-age students diagnosed with autism were taught to expressively label nouns using a DTT format and a FT format. A between-treatments comparison of the total number of nouns retained at 6 weeks post intervention was also conducted to compare retention. The results of this study showed that FT was superior to DTT in all of these areas. (Contains 1 figure.)
