Promoting the development of verbal responses using instructive feedback.

Shillingsburg, Frampton, Cleveland, and Cariveau (2018) taught listener and tact by feature, name-feature intraverbal, and feature-name intraverbal responses across sets and reported emergence of responses that were not directly trained for 6 individuals diagnosed with autism spectrum disorder (ASD). The current study was a systematic replication with the addition of instructive feedback (IF) with 2 children diagnosed with ASD. During trials for previously mastered listener by name responses (e.g., "Point to Tennessee" and child selects a picture of Tennessee), the experimenters provided related IF (e.g., "The capital of this state is Nashville"). After 3 sessions, we evaluated the effects of IF on related verbal responses (e.g., listener by feature, tact by feature, name-feature intraverbal, and feature-name intraverbal) across sets probes. We observed increased correct responses for related verbal responses; replicating Shillingsburg et al. Results suggest that the inclusion of IF may increase the efficiency of verbal behavior programming.
