Dogs exposed to inescapable shocks in a Pavlov harness subsequently fail to learn to escape shook in a shuttle box. In agreement with many previous investigations, Experiment 1 found that rats exposed to inescapable shock do not fail to learn to escape in a shuttle box. Experiments 2, 3, and 4 varied the number, intensity, and temporal interval between inescapable shocks and did not find failure to learn in the shuttle box. An analysis of responding in the shuttle box revealed that rats shuttle rapidly from the very first trial, whereas dogs acquire shuttling more gradually. Experiments 5 and 6 revealed that rats exposed to inescapable shock will fail to learn to escape if the escape response is one that is acquired more gradually. Experiment 5 utilized a double crossing of the shuttle box as the escape response and Experiment 6 utilized a wheel-turn response.
The study evaluates a comprehensive, ecological approach to behavioral family intervention with a family of a child with severe disabilities and severe problem behaviors. A multiple-baseline design across family routines assessed the functional relationship between parent implementation of a multicomponent intervention and improvement in child behavior and successful completion of routines. Results indicate durable improvements in child behavior and routine completion. Associated outcomes included generalized improvements in child behavior and enhanced activity patterns. Results verify the efficacy of the approach for ameliorating problem behaviors and empowering parents to build successful family routines. The value of collaborative research with families is briefly discussed.
Positive behavior support (PBS) is an applied science that uses educational and systems change methods (environmental redesign) to enhance quality of life and minimize problem behavior. PBS initially evolved within the field of developmental disabilities and emerged from three major sources: applied behavior analysis, the normalization/inclusion movement, and person-centered values. Although elements of PBS can be found in other approaches, its uniqueness lies in the fact that it integrates the following critical features into a cohesive whole: comprehensive lifestyle change, a lifespan perspective, ecological validity, stakeholder participation, social validity, systems change and multicomponent intervention, emphasis on prevention, flexibility in scientific practices, and multiple theoretical perspectives. These characteristics are likely to produce future evolution of PBS with respect to assessment practices, intervention strategies, training, and extension to new populations. The approach reflects a more general trend in the social sciences and education away from pathology-based models to a new positive model that stresses personal competence and environmental integrity. Edward G. Carr 4The fourfold purpose of this article is to (a) provide a definition of the evolving applied science of positive behavior support (PBS); (b) describe the background sources from which PBS has emerged; (c) give an overview of the critical features that, collectively, differentiate PBS from other approaches; and (d) articulate a vision for the future of PBS.
Nonaversive behavior management is an approach to supporting people with undesirable behaviors that integrates technology and values. Although this approach has attracted numerous proponents, more adequate definition and empirical documentation are still needed. This article presents an introduction to the nonaversive approach. Important definitions are suggested, and three fundamental elements are presented: (a) an emerging set of procedures for supporting people with severe challenging behavior; (b) social validation criteria emphasizing personal dignity; and (c) a recommendation for prohibition or restriction of certain strategies. These elements are defined in hopes of stimulating further discussion and empirical analyses of positive behavioral support.
Reporting guidelines, such as the Consolidated Standards of Reporting Trials (CONSORT) Statement, improve the reporting of research in the medical literature (Turner et al., 2012). Many such guidelines exist and the CONSORT Extension to Nonpharmacological Trials (Boutron et al., 2008) provides suitable guidance for reporting between-groups intervention studies in the behavioral sciences. The CONSORT Extension for N-of-1 Trials (CENT 2015) was developed for multiple crossover trials with single individuals in the medical sciences (Shamseer et al., 2015; Vohra et al., 2015), but there is no reporting guideline in the CONSORT tradition for single-case research used in the behavioral sciences. We developed the Single-Case Reporting guideline In BEhavioural interventions (SCRIBE) 2016 to meet this need. This Statement article describes the methodology of the development of the SCRIBE 2016, along with the outcome of 2 Delphi surveys and a consensus meeting of experts. We present the resulting 26-item SCRIBE 2016 checklist. The article complements the more detailed SCRIBE 2016 Explanation and Elaboration article (Tate et al., 2016) that provides a rationale for each of the items and examples of adequate reporting from the literature. Both these resources will assist authors to prepare reports of single-case research with clarity, completeness, accuracy, and transparency. They will also provide journal reviewers and editors with a practical checklist against which such reports may be critically evaluated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
