Conventional Versus Progressive DTT

Recorded in 2024


There are a variety of recommendations or guidelines for interventionists when implementing discrete trial teaching (DTT) for individuals diagnosed with autism spectrum disorder (ASD). These guidelines typically involve a protocol being the main source of control for the interventionist’s behavior that outlines what instruction to give, reinforcer to use, and when to use and fade prompting strategies. However, recent research has demonstrated strategies in which the main sources of control for the interventionist are relevant to the learner’s behavior and involves in-the-moment assessment, or clinical judgement, when making decisions to modify variables within intervention. The purpose of this study was to compare the effectiveness of conventional and progressive approaches to DTT when teaching tact relations (sometimes referred to as expressive labels) to children diagnosed with ASD. The effectiveness and efficiency of each approach was evaluated across several dependent variables. The results of a randomized clinical trial will be discussed with respect to implications for clinical practice and future research.
