Fluent listener behavior is a fundamental repertoire that affects the learning and development of speaker repertoires. We used a concurrent multiple-baseline design across 3 preschool-aged participants with disabilities to evaluate the effectiveness of a listener emersion protocol on increasing listener fluency. Prior to intervention, the participants demonstrated difficulty following vocal directions. The dependent variables were the rate per minute of correct and incorrect listener responses to vocal directions. The listener emersion protocol required participants to follow 4 sets of 5 one-step vocal directions. Results of this study indicate that listener fluency improved with an increased rate of correct responses across all 3 participants as a function of the listener emersion protocol.
