Exploring Antecedent Exercise and Stereotypic Behaviors: A Behaviorist Book Club Discussion

Introduction

Welcome to the Behaviorist Book Club podcast! I'm your host, Matt Harrington, and in today's episode, we're delving into a fascinating topic that explores the effects of antecedent exercise on stereotypic behaviors exhibited by individuals with autism spectrum disorder (ASD). So, whether you're a seasoned practitioner or just getting started, this episode will provide you with insights into the world of behavior analysis, helping you better understand how to support clients in achieving meaningful behavior change.

Understanding the Context

Before we dive into the details, it's crucial to set the stage by acknowledging a couple of key points. First and foremost, stereotypic behaviors should not be targeted for reduction unless there are compelling safety concerns or specific requests from the individual or their caregiver. The focus should always be on the well-being and preferences of the person receiving the intervention. In recent years, the field of behavior analysis has evolved, recognizing the importance of understanding and respecting the reasons behind stereotypy, particularly as communicated by autistic adults. For the purposes of this discussion, we are assuming that the stereotypy is in the form of significant self-injurious behavior, and there is a need to reduce the behavior so that other more successful coping skills can be plugged into the client’s repertoire.

Antecedent Exercise: Not Your Typical Workout

Let's start by clarifying what we mean by "antecedent exercise." Unlike the grueling drills you might associate with exercise, antecedent-based exercise in this context involves activities that are already highly preferred by the individual, such as roller skating, trampoline bouncing, jogging, stretching, walking, and even throwing a ball. These activities are strategically introduced before a more challenging task or learning session, with the aim of creating a positive context and potentially reducing stereotypic behaviors.

The Matching vs. Competing Stimulation Debate

A key question arises when discussing antecedent exercise: Is it a matching or competing stimulus? This distinction holds significance because it influences how we interpret the results. If antecedent exercise results in a reduction of stereotypy and other behaviors, it might indicate fatigue, suggesting a competing stimulus. On the other hand, if only stereotypy is reduced and other behaviors increase, it leans towards a matching stimulus. This opens up intriguing connections with sensory diets and occupational therapy, emphasizing the importance of a multidisciplinary approach.

Insights from a Lit Review

A literature review encompassing 14 studies on antecedent-based exercise shed light on its effectiveness. Surprisingly, all applications were found to be effective in reducing stereotypy. However, it's essential to approach these results with caution due to publication bias—studies are more likely to be published when they show positive outcomes. While these findings are promising, it's important not to jump to the conclusion that antecedent exercise is a one-size-fits-all solution.

Collaborating for Successful Solutions

As behavior analysts, we're equipped to analyze and understand behavior patterns. However, the case of antecedent exercise and stereotypic behaviors calls for collaboration with other professionals, such as occupational therapists. Sensory diets, often used in occupational therapy, parallel some aspects of antecedent exercise, providing a fresh perspective on matching and competing stimuli. This intersection highlights the power of working together to achieve comprehensive and effective solutions for clients.

Conclusion

In this episode of the Behaviorist Book Club podcast, we've explored the intriguing world of antecedent exercise and its impact on stereotypic behaviors. We've delved into the nuances of matching and competing stimuli, considered the role of sensory diets, and emphasized the importance of collaboration between behavior analysts and other professionals. As we continue to learn and grow in the field of behavior analysis, let's remember that every individual is unique, and our approaches should always prioritize their well-being, preferences, and individuality. Thank you for joining us, and until next time, keep seeking knowledge and making a positive impact in the lives of those you serve.
