A Tutorial on Indicating Responses and Their Importance in Mand Training

One of the most critical intervention strategies when working with individuals with significant language delays associated with autism spectrum disorder and related developmental delays is teaching mands. For mand training to be effective, an establishing operation (EO) must be in effect, yet EOs are often difficult to observe. Before learning to mand, an individual may point to or approach a reinforcer, which likely indicates an EO related to that reinforcer, and may be considered an indicating response (IR). Observing an IR before prompting a mand increases the likelihood that the prompt is delivered when an EO is in effect and that the response is truly a mand. Missing from the literature is a consistent definition of IRs and a robust set of guidelines for using them in practice. In this tutorial, we review the terms and topographies of IRs in the literature to arrive at a definition of IRs. We then provide practical, research-based recommendations for using IRs during mand training, as well as assessing, selecting, teaching, and replacing IRs. Last, we provide tools and resources related to decision making and data collection with respect to IRs.
