Studies on teaching tacts to individuals with autism spectrum disorder (ASD) have primarily focused on visual stimuli, despite published clinical recommendations to teach tacts of stimuli in other sensory domains as well. In the current study, two children with ASD were taught to tact auditory stimuli under two stimulus-presentation arrangements: isolated (auditory stimuli presented without visual cues) and compound (auditory stimuli presented with visual cues). Results indicate that compound stimulus presentation was a more effective teaching procedure, but that it interfered with prior object-name tacts. A modified compound arrangement in which object-name tact trials were interspersed with auditory-stimulus trials mitigated this interference.
