Abstract Behavior analysis has a long history of using nonhuman animals in basic research, classroom teaching, and applied practice, yet discipline-specific guidance for competent and ethical animal work remains limited. This paper reviews historical and contemporary trends in animal use within behavior analysis, including the decline of traditional animal laboratories, growing interest in invertebrate models, and expansion of behavior-analytic work into homes, shelters, zoos, and other applied settings. We argue that although behavioral principles are broadly applicable, competence in animal work requires more than general behavior-analytic training. In the absence of integrated guidance for developing and evaluating that competence, behavior analysts may face serious risks to animal welfare, human safety, the relationship between behavior analysis and the broader animal behavior community, and the field’s ability to advance a comprehensive science of behavior. In response, we propose a set of six minimum standards for animal-focused work in behavior analysis: (1) interdisciplinary knowledge of animal behavior, (2) species-specific knowledge, (3) skill fluency, (4) ethical conduct, (5) safe practices, and (6) appropriate mentorship strategies. A practical self-assessment tool accompanies these standards to help professionals determine their scope of competence. We hope these standards initiate a needed conversation about what is required to work with animals competently in behavior analysis and support the development of guidelines as structured, explicit, and carefully maintained as those established for human-focused work.
Abstract Burnout, compassion fatigue, secondary traumatic stress, and attrition represent significant and growing challenges in applied behavior analysis. These challenges all collectively impact practitioner well-being, yet strategies to support such well-being initiatives have received limited systematic attention in the behavior-analytic literature. In this discussion, I posit that the concept of self-compassion represents an important gap in supporting practitioner well-being. Self-compassion, as defined by Neff, includes three interrelated components: (1) responding to personal suffering with kindness rather than self-judgment, (2) recognizing struggle as part of the shared human condition, and (3) maintaining balanced awareness of difficult emotions. Across health, education, and psychology fields, self-compassion has demonstrated strong empirical support as a protective factor against burnout, emotional exhaustion, anxiety, experiential avoidance, and compassion fatigue. Drawing on Neff’s model and translating its components into behavior-analytic terms grounded in radical behaviorism, relational frame theory, and acceptance and commitment training, in this article, I describe a conceptual foundation for self-compassion within applied behavior analysis, propose a four-component training framework, and offer directions for future research.
Abstract Large language models (LLMs) are a type of AI (artificial intelligence). They are large-scale, sophisticated neural networks trained on vast amounts of text data to mimic human language. The increased adoption of LLMs warrants an analysis of their substantial, rapidly growing environmental footprint. This paper is structured in three broad sections. First, we offer a behavior-analytic lens into the rapidly increasing adoption of this technology. The analysis is provided at the individual, organizational, and cultural levels, with a discussion of efficiency gains being absorbed into productivity contingencies. Second, we provide a cradle-to-grave overview of the environmental impact of this technology: cradle (building the infrastructure), life (training and running the model), grave (disposal of electronic waste), and the potential infrastructure lock-in costs. The analysis includes a discussion of embedded carbon, an area often overlooked in discussions of environmental impacts. To close, we provide suggestions for behavior analysts at the individual level to the cultural level, with an emphasis on where leverage is most possible.
Abstract The peak interval procedure, in which subjects learn to cluster their anticipatory responses around delays to biologically critical outcomes, provides benchmarks for interval timing models. These include (a) the bistable response regime demarcated by an abrupt increase (start times) and a decrease (stop times) in response rates around the target time in individual trials; (b) bell‐curve‐shaped average response curves that superpose on a relative time scale; (c) lower coefficient of variation of stop times than start times; and (d) specific correlational patterns between these parameters, their mean, and difference. This article presents a multilayer computational model that predicts these key markers of timing behavior in the peak interval procedure. The first layer constitutes the clock stage, comprising uncoupled diffusion processes approaching a single boundary. The first crossing of the threshold for each diffusion process is broadcast to the downstream motor layer. The motor layer integrates the broadcast signals with a leak term scaled by the drift rate to avoid saturation and reset of motor system activity. The model is extended to account for real‐time temporal discrimination. This family of models departs from the single‐clock approach to modeling and meets the core empirical benchmarks of timing behavior.
Abstract Interventions seeking to reduce impulsive choice in nonhuman animals (i.e., preference for smaller sooner over larger later rewards [SSR vs. LLR]) often require long training durations. However, prior studies illustrate how a brief course of Pavlovian training can reduce rodents' impulsive choice by attracting them to the LLR and by providing an appetitive Pavlovian conditioned stimulus (CS) contingent on LLR choices. In these studies, the comparison group completed unpaired (UN) training where the CS and US never co‐occurred. The present study added a truly random control (TRC) group to evaluate whether UN training made the CS aversive, exaggerating the effect of Pavlovian training on self‐control. Following Pavlovian (PAV), UN, or TRC training, a lever CS was inserted into the chamber during half the delay to the LLR. PAV rats were significantly more attracted to the lever during training and chose the LLR significantly more often than TRC or UN rats. Significant sex differences were detected, with self‐control influencing the effects of Pavlovian training predominantly observed in male rats. Because sex differences in self‐control outcomes were not observed in the only other study to examine the effects of presenting an appetitive CS after LLR choices, possible reasons for this interexperiment difference are discussed.
Resumo Diversos estudos têm relatado déficits no processamento temporal em doenças neurodegenerativas como a doença de Parkinson e a doença de Alzheimer. Esses déficits podem ser quantificados por paradigmas de timing de intervalo que requerem que os participantes estimem ou produzam um intervalo de vários segundos e demandam memória de trabalho para regras temporais, bem como atenção ao tempo. O desempenho em timing pode ser quantificado por uma variedade de medidas; no entanto, duas métricas relativamente universais incluem: (1) acurácia temporal, definida como a estimativa temporal média, e (2) precisão temporal, refletida pela variabilidade das estimativas temporais. Examinamos a acurácia e a precisão temporais em uma meta-análise de 14 estudos com pacientes com doença de Parkinson e 10 estudos com pacientes com doença de Alzheimer. É notável que, em ambas as doenças, a precisão temporal mostrou-se confiavelmente prejudicada across os estudos, enquanto a acurácia temporal foi afetada na doença de Alzheimer, mas não na doença de Parkinson. Nossa meta-análise sugere que, apesar da diversidade de paradigmas de timing de intervalo e da complexidade da doença de Parkinson e da doença de Alzheimer, a precisão temporal é consistentemente prejudicada nessas doenças. Esses resultados avançam o timing de intervalo como um ensaio confiável para estudar a disfunção cognitiva na doença de Parkinson e na doença de Alzheimer e podem se estender a outros transtornos neurológicos e psiquiátricos.
Abstract This essay analyzes faculty self-censorship behavior amid political interference in Florida public higher education. Political interference increasingly regulates faculty behavior through statutes, administrative policies, and institutional directives that alter teaching, research, and scholarly discourse. We examine faculty self-censorship as rule-governed behavior using an established taxonomy of rules (Pelaez, 2013; Pelaez & Moreno, 1998) as its primary theoretical framework. The taxonomy articulates five interacting dimensions of rules: (a) explicitness, (b) accuracy (correspondence), (c) complexity, (d) source, and (e) temporal relations. These five dimensions are used to explore how legal and organizational rule systems influence individual faculty behavior under conditions of political intimidation. Recent concepts from higher education and political philosophy scholarship, including anticipatory obedience and repressive legalism, are integrated within this behavior-analytic framework. Florida’s public higher education system and the Eleventh Circuit’s decision affirming the injunction against the Stop WOKE Act serve as a contemporary case study illustrating how ambiguous, incongruent, and externally imposed rules may generate self-censorship despite changing legal contingencies.
Abstract Type I errors, or false positives, occur when a researcher erroneously concludes that the independent variable caused a change in the dependent variable. Type I errors can result in resources being misused in both research and practice. Although Type I errors are most often associated with group design paradigms, researchers using single-case experimental designs are also susceptible to making Type I errors. In this article, we describe the research on Type I errors in single-case experimental designs across analytic methods, including visual analysis, machine learning, effect estimation, and randomization approaches. We also suggest ways that each analytic method can be used to mitigate Type I errors and highlight aspects of Type I error in single-case experimental designs that are understudied and in need of additional research.
Abstract Impulsive choice—preference for a smaller-sooner over a larger-later reward—is a transdiagnostic risk factor for behaviors that harm human health. Preventing a temporally extended pattern of impulsive choice should be a translational research priority. No existing intervention meets all the criteria outlined in this article of an ideal school-based prevention program: low cost, low teacher effort, fast-acting, and capable of producing lasting, generalizable reductions in impulsive choice. Here, we evaluate Pavlovian conditioning as a candidate approach. Our review is informed by evidence from nonhuman laboratory experiments and kindergarten classroom studies examining whether appetitive Pavlovian conditioning protocols can reduce impulsive choice and related behaviors. Laboratory experiments demonstrate that a brief Pavlovian conditioning protocol establishes a conditioned stimulus (CS) that may then be strategically used to reduce impulsive choice in rats by serving as an attractive antecedent and/or an appetitive delay-bridging stimulus. Studies conducted in kindergarten classrooms show that a class-wide protocol can establish an appetitive CS with minimal teacher training and classroom disruption. Presenting the CS during an in-situ waiting task reduced children's challenging behaviors and presenting it during academic-choice tasks increased children's willingness to work for larger rewards. This preliminary evidence supports the continued exploration of Pavlovian conditioning approaches to efficiently prevent patterns of impulsive choice that cumulate over time to negatively affect human health and wellbeing.
Abstract Case-specific effect sizes have been developed to supplement the visual analysis of line-graphed data in single-case design research by quantitatively summarizing intervention effectiveness. This article provides background on case-specific effect sizes and describes when they can effectively complement visual analysis. We discuss several distinct families of case-specific effect size metrics, including nonoverlap indices (e.g., nonoverlap of all pairs), standardized measures (e.g., standardized mean difference), response ratios (e.g., percentage change), and goal attainment (e.g., percent of goal obtained). Furthermore, we discuss the assumptions and limitations that hold for all families of case-specific effect sizes and the assumptions and limitations of each type of case-specific effect size. In conclusion, we provide guidance for determining when these metrics are appropriate for a single-case design study and present a decision framework to help researchers select the most suitable effect size measure(s), if any, for their data.
Abstract Renewal, reinstatement, and other forms of recovery of learned behavior after extinction have been interpreted in terms of the concept of context . Context is defined here as the field of stimuli that is interrelated with the behavior of an individual in the present. Two important classes of stimuli that comprise context are discriminative stimuli and motivating operations. Two experiments examined interactions between discriminative and motivational aspects of context in the renewal and reinstatement of operant behavior following extinction in mice. In Experiment 1, mice received all operant acquisition and extinction sessions under 24 hr of food deprivation. In Experiment 2, mice received half of acquisition and extinction sessions under 24 hr of deprivation and the other half under nondeprived conditions. In both experiments, mice were tested for renewal and reinstatement after extinction, one group under 24 hr of deprivation and the other nondeprived. Results showed that the extent to which recovery occurred depended on relations between motivating operations (a) during acquisition/extinction learning and (b) during tests for renewal and reinstatement. Translational implications for the study of recovery of behavior after extinction in nonlaboratory circumstances are discussed.
