A Review of Recent Research on the Manipulation of Response Effort in Applied Behavior Analysis.

Response effort refers to the distance, force/pressure, or number of discrete behaviors required to engage in a response. In applied behavior analysis, response effort has been used as an independent variable to address a variety of target responses. In this manuscript, we summarize recent clinical and organizational studies in which response effort was manipulated to increase a desirable behavior or decrease a problematic behavior. Recent clinical applications include the manipulation of response effort to decrease self-injurious behavior and pica and increase appropriate eating, compliance, and manding. Recent organizational applications include the manipulation of response effort to increase safety and recycling. We also review the collection of data on treatment integrity, social validity, and maintenance in response effort research and analyze the effectiveness of response effort manipulations. We conclude by discussing the putative behavioral mechanisms responsible for the effects of response effort manipulations and by providing some directions for future research.
