An Abbreviated Evaluation of the Efficiency of Listener and Tact Instruction for Children with Autism.

We assessed the efficiency of tact and listener training for eight participants with autism spectrum disorder. Tact and listener probes were conducted in baseline for all target sets, and then tact training was initiated with one and listener training with another. Following mastery of one set, tact and listener probes were conducted with only the sets assigned to the same modality of training (i.e., sets 1, 3, and 5 for tact; sets 2, 4, and 6 for listener). Training and probes were repeated for all sets. The measures of efficiency included the number of skills mastered through direct training, the number of skills that emerged without training, the number of trials-to-criterion, and maintenance of skills. Clinical programming based on each participant's results is discussed. For six participants, tact training was more efficient than listener training across multiple measures. For the remaining two participants, tact training and listener training were considered equivalent.
