There has been a recent increase in the variables that impact the maintenance, response strength, and relapse of behavior targeted for change in applied contexts. The focus of much of this research has been the application of behavioral momentum theory (BMT) to the assessment, treatment, and treatment maintenance related to problem behavior. In this group of presentations, data will be presented that focuses of various consequence and stimulus variables that may impact human behavior in translational and applied contexts. Collectively, the results of this group of studies suggest that variables other than reinforcer rate, magnitude of reinforcement, etc. can impact response maintenance, strength and relapse. The results of these studies have direct implications for designing effective treatments for individuals who engage in severe problem behavior and will be discussed with respect to treatment design, BMT, and programming for the long-term effectiveness of behavioral treatments for those individuals.

The current investigation evaluated the effect of reinforcer potency on the persistence of task completion for a participant (Nick) who engaged in problem behavior to escape from demands. Interobserver agreement was calculated on at least 30% of each condition and averaged 98%. During Phase 1, a unit price evaluation was conducted to evaluate the potency of two stimuli (raisins and iPad). Nick chose to complete two times the amount of work to earn raisins over iPad, suggesting that raisins were the more potent reinforcer. During Phase 2, baseline data for Nick's task completion were collected within a multiple schedules design. Task completion was placed on extinction during this phase. In contrast, task completion was reinforced on a continuous schedule of reinforcement with access to iPad when Nick worked for orange tokens and raisins when Nick worked for yellow tokens during Phase 3. Extinction (Phase 4) was implemented after establishing similar histories of reinforcement for the orange and yellow stimulus conditions. Results showed that task completion under the stimulus condition associated with the delivery of raisins, or the more potent reinforcer, persisted longer under extinction conditions. These data will be discussed in terms of their basic and applied implications.

One function-based approach to the treatment of destructive behavior with considerable empirical support is functional communication training (FCT). Although FCT has been shown to be highly effective when implemented in controlled environments by well-trained therapists, treatment relapse often occurs when a caregiver is unable to accurately carry out the procedures in the natural environment. For example, a caregiver of a child with severe aggression may be unable to deliver the functional reinforcer (e.g., attention) when the child emits the functional communication response (FCR) because the caregiver is attending to a sick sibling. During this time when the FCR is exposed to extinction, the childs aggression often increases, a form of relapse called resurgence. Behavioral momentum theory (BMT) provides a quantitative method for making stimulus- and consequence- control refinements to FCT that can function as behavioral inoculation so that treatment relapse in the form of resurgence of destructive behavior is greatly mitigated or prevented altogether. Interestingly, some predictions of BMT are somewhat counterintuitive and in direct opposition to clinical procedures recommended as best practices by prominent clinical researchers. In this presentation, I will discuss these refinements of FCT along with illustrative data sets and potential directions for future research.
