Evaluating the influence of postsession reinforcement on choice of reinforcers

Reinforcer value moderates response magnitude and persistence during extinction: A randomized trial

Extinction bursts, or temporary increases in rates and intensities of behavior during extinction, can preclude the inclusion of extinction in intervention packages meant to suppress severe challenging behavior. To identify underlying behavioral mechanisms responsible for response persistence and bursting, 69 adults with developmental disabilities completed a low-stakes translational investigation employing a 2 × 2 factorial, crossed, and randomized matched blocks design, with batched randomization logic. In each of the four test groups, we made distinct antecedent manipulations with two value parameters commonly studied through behavioral economics (i.e., demand intensity, Pmax) and evaluated the extent to which each of these manipulations influenced target responding during extinction. Although we found statistically significant differences attributable to both parameters, variations in reinforcer consumption relative to demand intensity were most influential across all dependent variables. This outcome implicates consumption relative to demand intensity as both a mitigating and exacerbating preextinction factor that influences the prevalence of adverse collateral extinction effects (e.g., bursts).

Common Practices used to Establish and Implement Token Economies in Clinical and Instructional Settings: A Survey of BACB Certificants

Token economies are among the most widely used procedures in behavior analysis and research on token economies has spanned over 80 years. Several textbooks have outlined the essential components of token economies and suggested how they can be trained and implemented in practice. However, procedures evaluated in applied research can vary from how those procedures are implemented in clinical practice. It is conceivable that the way in which token economies are implemented in clinical settings does not resemble the procedures described in research and behavior analytic textbooks. We surveyed 255 board certified behavior analysts and board certified assistant behavior analysts about their commonly used practices when training and implementing token economies with individuals with autism and other neurodevelopmental disorders. Results suggest that certain aspects of token economies in practice often bear only superficial resemblance to how they are described in textbooks.

A Model of Support for Families of Children With Autism Living in the COVID-19 Lockdown: Lessons From Italy

Italy has been the European country most affected by the COVID-19 pandemic to date and has been in social lockdown for the longest period of time compared to other countries outside China. Almost overnight, Italian behavior analysts were faced with the challenge of setting up remotely whole-family systems aimed at maintaining adaptive skills and low levels of challenging behavior to be carried out solely by caregivers. Given these extraordinary circumstances, the protocols available from the applied behavior-analytic, parent training, and autism literature did not appear to fully meet the needs of parents having to be with their children under extreme levels of stress in a confined space with limited reinforcers for 24 hr a day, 7 days a week. To meet this unprecedented challenge, we developed a dynamic and holistic protocol that extended to the full day and that recognized the need for sustainable intervention delivered solely by parents, who were often looking after more than one child. These practices are presented in this article, together with a discussion of lessons we have learned thus far, which may be useful for behavior analysts working in other regions in which the effects of the pandemic are not yet fully realized. Although somewhat unorthodox, we include some parent comments at the end with the goal of sharing the parent perspective in real time as this pandemic unfolds across the world.

An Evaluation of Operant Behavioural Economics in Functional Communication Training for Severe Problem Behaviour

Objective: This single-case experiment examined the use of behavioural economic concepts in a function-based treatment for problem behaviour. Methods: Behavioural economic analyses were used to evaluate the strength of functions of problem behaviour and this information was used to inform elements of function-based treatment for one child with a neurodevelopmental disorder. Results: Findings from this experiment indicated that the incorporation of behavioural economic measures resulted in positive treatment effects that were maintained throughout all phases of the evaluation, including those implemented by caregivers. Conclusions: These results suggest that behavioural economic concepts and procedures can be successful adjuncts to evidence-based assessments and treatments for problem behaviour.

A progressive-duration schedule of reinforcement

We describe a schedule of reinforcement involving systematic, within-session increases in response-duration requirements. Rats received access to appetitive reinforcers for depressing and holding down a response lever. Duration requirements increased after each reinforcer delivery. Sessions ended when reinforcement criteria were unmet for a period of ten minutes. Breaking points, defined as the terminal duration requirement in effect prior to the end of the session, stabilized when environmental conditions were held constant. Breaking points were sensitive to manipulations of both food deprivation and reinforcer quality. Analogous to progressive-ratio schedules, progressive-duration schedules may provide an assay for measuring the amount of behavior an organism will emit for a given reinforcer under current motivational conditions.

Behavioral economics: a tutorial for behavior analysts in practice

In recent years, behavioral economics has gained much attention in psychology and public policy. Despite increased interest and continued basic experimental studies, the application of behavioral economics to therapeutic settings remains relatively sparse. Using examples from both basic and applied studies, we provide an overview of the principles comprising behavioral economic perspectives and discuss implications for behavior analysts in practice. A call for further translational research is provided.

Applied implications of reinforcement history effects

Although the influence of reinforcement history is a theoretical focus of behavior analysis, the specific behavioral effects of reinforcement history have received relatively little attention in applied research and practice. We examined the potential effects of reinforcement history by reviewing nonhuman, human operant, and applied research and interpreted the findings in relation to possible applied significance. The focus is on reinforcement history effects in the context of reinforcement schedules commonly used either to strengthen behavior (e.g., interval schedules) or commonly used to decrease behavior (e.g., extinction).
