Tutorial: Lessons Learned for Behavior Analysts from Data Scientists

Big data is a computing term used to refer to large and complex data sets, typically consisting of terabytes or more of diverse data that is produced rapidly. The analysis of such complex data sets requires advanced analysis techniques with the capacity to identify patterns and abstract meanings from the vast data. The field of data science combines computer science with mathematics/statistics and leverages artificial intelligence, in particular machine learning, to analyze big data. This field holds great promise for behavior analysis, where both clinical and research studies produce large volumes of diverse data at a rapid pace (i.e., big data). This article presents basic lessons for the behavior analytic researchers and clinicians regarding integration of data science into the field of behavior analysis. We provide guidance on how to collect, protect, and process the data, while highlighting the importance of collaborating with data scientists to select a proper machine learning model that aligns with the project goals and develop models with input from human experts. We hope this serves as a guide to support the behavior analysts interested in the field of data science to advance their practice or research, and helps them avoid some common pitfalls.

Prompting and Modeling of Coping Strategies during Childbirth

There is ample evidence to suggest that upright positions and mobility during labor improve birth outcome, including shorter duration of childbirth and reduced risk of cesarean section. The use of nonpharmacological interventions for pain management during childbirth are recommended by major health-care institutions and medical providers, however, the current methodologies for training coping strategies for use during labor have not shown to be effective on mobility or birth outcome. The purpose of this study was to apply an in-vivo teaching technology to the current childbirth model to prompt an imitative repertoire of empirically demonstrated labor coping strategies. Results of this study concluded that the introduction of a software using immediate prompting and video modeling increased the frequency and variability of labor behaviors during unmedicated labor for birthing persons and their partners.

The Evolution of the Conceptually Systematic Dimension and Its Current Functions in Applied Behavior Analysis

What does it mean to be conceptually systematic in contemporary applied behavior analysis (ABA) research and practice? To answer this question, the present study conducted a historical analysis of ABA scholars' interpretations of the conceptually systematic dimension of ABA over the last 55 years. The present article found the current characteristics of the conceptually systematic dimension are indeed sufficient to suggest ABA's conceptual independence from the experimental analysis of behavior or any other subdisciplines of behavior analysis. Based on this finding, this article addresses the challenges in contemporary ABA field such as ABA's own basic and applied continuum, translational research, and its relationship with other disciplines' research and practice.

Influence of white-light-emitting diodes on primary visual cortex layer 5 pyramidal neurons (V1L5PNs) and remodeling by blue-light-blocking lenses

Studies have explored the consequences of excessive exposure to white-light-emitting diodes (LEDs) in the retina. Hence, we aimed to assess the implications of such exposure on structural alterations of the visual cortex, learning and memory, and amelioration by blue-light-blocking lenses (BBLs). Eight-week-old Wistar rats (n = 24) were used for the experiment and divided into four groups (n = 6 in each group) as control, white LED light exposure (LE), BBL Crizal Prevencia-1 (CP), and DuraVision Blue-2 (DB). Animals in the exposure group were exposed to white LED directly for 28 days (12:12-h light/dark cycle), whereas animals in the BBL groups were exposed to similar light with BBLs attached to the LEDs. Post-exposure, a Morris water maze was performed for memory retention, followed by structural analysis of layer 5 pyramidal neurons in the visual cortex. We observed a significant difference (P < 0.001) in the functional test on day 1 and day 2 of training in the LE group. Structural analysis of Golgi-Cox-stained visual cortex layer 5 pyramidal neurons showed significant alterations in the apical and basal branching points (p < 0.001) and basal intersection points (p < 0.001) in the LE group. Post hoc analysis revealed significant changes between (p < 0.001) LE and CP and (p < 0.001) CP and DB groups. Constant and cumulative exposure to white LEDs presented with structural and functional alterations in the visual cortex, which are partly remodeled by BBLs.

Individualized behavior-based safety-leadership training: A randomized controlled trial

INTRODUCTION

Construction site managers play a critical role in occupational safety in the construction industry. This study aimed to develop and test a method for training construction site managers in positive feedback and active listening by incorporating the behavioral training components of behavior analysis, goal setting, practice with behavior feedback, homework, and maintenance planning into individualized behavior-based safety-leadership training (IBST), and to assess the effect of IBST on construction site managers' safety-leadership behaviors and performance.

METHOD

In a naturalistic randomized controlled trial, construction site managers were randomly assigned to an experimental group (n = 16) or a control group (n = 19). The experimental-group managers received IBST, while the control-group managers received no training. Paired sample t-tests on pre- to post-training (i.e., six weeks after the final training session) were performed separately for the experimental- and control-group managers.

RESULTS

The safety-leadership behaviors of the experimental-group managers improved in terms of favorable feedback (d = 0.99, p <.01), safety-specific feedback (d = 0.89, p =.02), behavior-specific feedback (d = 0.66, p =.02), antecedent listening (d = 0.68, p =.02), and consequential listening (d = 0.78, p =.01). In addition, safety-leadership performance improved in terms of transformational leadership (d = 0.78, p =.01) and contingent-reward leadership (d = 0.64, p =.02). No significant change was found for the control-group managers.

CONCLUSIONS

The results indicate that behavior analysis, goal setting, practice with behavior feedback, homework, and maintenance planning are effective behavioral training components of safety-leadership training. Positive feedback and active listening were also found to be important behavioral requisites for transformational and contingent-reward leadership.

PRACTICAL APPLICATIONS

IBST can be used to develop occupational safety in the construction industry by improving construction site managers' safety-leadership behaviors and performance.

Promoting Reciprocal Relations across Subfields of Behavior Analysis via Collaborations

Several barriers may inhibit the growth of behavior analysis as a more integrated and collaborative field. Two such barriers are siloed environments that reinforce a basic-applied distinction, and a lack of translational research pathways. We describe the perils of silos, and elaborate on potential solutions to increase reciprocal relations among subfields in behavior analysis. We promote a five-tiered system to classify research in behavior analysis, and discuss literature on cultivating effective intra and cross-disciplinary collaborations, including using the framework of metacontingencies to understand collaborations. We also propose quantitative and qualitative measures to examine whether the potential solutions increase intra and interdisciplinary interactions. These measures include bibliometric (e.g., citations across fields), sociometric (e.g., social network analysis), and narrative analysis. We apply some of these measures to publications from 2011-2022 from the Journal of the Experimental Analysis of Behavior and Journal of Applied Behavior Analysis, and argue that behavior analysis overall may benefit from a more collaborative approach.

From beasts to bytes: Revolutionizing zoological research with artificial intelligence

Since the late 2010s, Artificial Intelligence (AI) including machine learning, boosted through deep learning, has boomed as a vital tool to leverage computer vision, natural language processing and speech recognition in revolutionizing zoological research. This review provides an overview of the primary tasks, core models, datasets, and applications of AI in zoological research, including animal classification, resource conservation, behavior, development, genetics and evolution, breeding and health, disease models, and paleontology. Additionally, we explore the challenges and future directions of integrating AI into this field. Based on numerous case studies, this review outlines various avenues for incorporating AI into zoological research and underscores its potential to enhance our understanding of the intricate relationships that exist within the animal kingdom. As we build a bridge between beast and byte realms, this review serves as a resource for envisioning novel AI applications in zoological research that have not yet been explored.

Lipidomic profiling study on neurobehavior toxicity in zebrafish treated with aflatoxin B1

Mycotoxin aflatoxin B1 (AFB1) has been proven to cause neurotoxicity, but its potential interference with the normal function of brain tissue is not fully defined. As the indispensable role of lipids in maintaining the normal function of brain tissue, the aim of this study is to clarify the effect of AFB1 short-term (7 days) exposure on brain tissue from the perspective of lipid metabolism. In this study, zebrafish were exposed to two concentrations (5, 20 μg/L). Through quantitative analysis of AFB1, the detection of AFB1 in zebrafish brain tissue was discovered for the first time, combined with the changes in zebrafish neurobehavior, the occurrence of brain injury was deduced. Subsequently, 1734 lipids in zebrafish brain tissue were mapped using ion mobility time-of-flight mass spectrometry (UPLC-QTOF-IMS-MS), which has great advantages in lipid detection. Comparative analysis of the abnormal lipid metabolism in zebrafish brain revealed 114 significantly changed lipids, mainly involving two pathways of sphingolipid metabolism and fatty acid degradation. This study discovered the detection of AFB1 in the brain and revealed a potential link between AFB1-induced behavioral abnormalities and lipid metabolism disorders in brain tissue, providing reliable evidence for elucidating the neurotoxicity of AFB1.

Behavior analysis and formative assessments in online oral medicine education during the COVID-19 pandemic

BACKGROUND

During the coronavirus disease 2019 (COVID-19) pandemic, traditional teaching methods were disrupted and online teaching became a new topic in education reform and informatization. In this context, it is important to investigate the necessity and effectiveness of online teaching methods for medical students. This study explored stomatology education in China to evaluate the development and challenges facing the field using massive open online courses (MOOCs) for oral medicine education during the pandemic.

AIM

To investigate the current situation and challenges facing stomatology education in China, and to assess the necessity and effectiveness of online teaching methods among medical students.

METHODS

Online courses were developed and offered on personal computers and mobile terminals. Behavioral analysis and formative assessments were conducted to evaluate the learning status of students.

RESULTS

The results showed that most learners had already completed MOOCs and achieved better results. Course behavior analysis and student surveys indicated that students enjoyed the learning experience. However, the development of oral MOOCs during the COVID-19 pandemic faced significant challenges.

CONCLUSION

This study provides insights into the potential of using MOOCs to support online professional learning and future teaching innovation, but emphasizes the need for careful design and positive feedback to ensure their success.

Toward a Data-based Approach to the Selection of Applied Behavior Analysis Program Characteristics

There is a paucity of data that describe how program characteristics relate to program outcome goals. This gap limits the use of data to guide and support decisions concerning the selection of applied behavior analysis (ABA) program characteristics. Therefore, the purpose of the present study was to describe a methodology for the evaluation of the relationships between program characteristics and program outcome goals in the context of identifying the ideal program characteristics to propose for a new master of science in ABA program at Franciscan Missionaries of Our Lady University (FranU). For FranU, 11 program characteristics, enrollment, and the 2019 board certified behavior analyst (BCBA) pass rates were selected as variables. We provide a description of the procedures, data analysis and a general overview of our findings. The utility of the methodology for future research is also discussed.

Supervision for Aspiring Behaviour Analysts in Australia: An Exploration of Current Practices, Challenges, and Opportunities

Effective supervision is a key component of the development of effective and ethical behavior analytic repertoires. However, the provision of supervision may be challenging in countries where behavior analysis is an emerging profession and there are few qualified practitioners. We conducted a mixed-methods survey study to examine the supervision practices of board certified behavior analysts (BCBAs) in Australia, and perceived challenges related to the provision of supervision. Respondents reported using a variety of supervisory practices to meet the demand for supervision, but a lack of time, resources, and geographical location posed challenges. Based on these findings, we provide several recommendations for addressing identified challenges. Although each recommendation has been contextualized to meet the needs of the Australian behavior analytic community, these recommendations may be useful in other parts of the world where behavior analysis is an emerging profession or there are few BCBAs to meet the needs of a growing behavior analytic workforce.

Identifying Trends in the Open-Access Behavior Analytic Literature via Computational Analyses (I): Simple Descriptions of Text

Published research in scientific journals are critical resources for researchers as primary sources about: what is important in the field, the direction the field is headed, how the field relates to other sciences, and as a historical record for each of these. In this exploratory study, we analyzed the articles of five behavior analytic journals to identify trends in these areas. To do this, we downloaded all available articles (N = 10,405) since the inception of five behavior analytic journals and one control journal. We then used computational techniques to turn the collection of raw text into a structured dataset for descriptive, exploratory analyses. We found consistent differences in the length and variability of published research across behavior analytic journals compared to a control journal. We also found increasing article lengths over time which, combined with the previous finding, may highlight changing editorial contingencies that influence the writing behavior of researchers. Further, we found evidence suggesting distinct (though still connected) verbal communities between the experimental analysis of behavior and applied behavior analysis. Lastly, keyword trends suggest that increased focus on "functional analyses," "problem behavior," and "autism spectrum disorder" currently dominates the research being published in these journals similar to the practitioner arm of behavior analysis. Researchers interested in studying published behavior analytic textual stimuli will find the corresponding open dataset useful. And, for those interested in computational analyses of these data, this first pass at simple descriptions provides a launching point for much fruitful future research.

Comparing Multiple Methods to Measure Procedural Fidelity of Discrete-trial Instruction

Procedural fidelity is the extent to which an intervention is implemented as designed and is an important component of research and practice. There are multiple ways to measure procedural fidelity, and few studies have explored how procedural fidelity varies based on the method of measurement. The current study compared adherence to discrete-trial instruction protocols by behavior technicians with a child with autism when observers used different procedural-fidelity measures. We collected individual-component and individual-trial fidelity with an occurrence-nonoccurrence data sheet and compared these scores to global fidelity and all-or-nothing, 3-point Likert scale, and 5-point Likert scale measurement methods. The all-or-nothing method required all instances of a component or trial be implemented without error to be scored correct. The Likert scales used a rating system to score components and trials. At the component level, we found that the global, 3-point Likert, and 5-point Likert methods were likely to overestimate fidelity and mask component errors, and the all-or-nothing method was unlikely to mask errors. At the trial level, we found that the global and 5-point Likert methods approximated individual-trial fidelity, the 3-point Likert method overestimated fidelity, and the all-or-nothing method underestimated fidelity. The occurrence-nonoccurrence method required the most time to complete, and all-or-nothing by trial required the least. We discuss the implications of measuring procedural fidelity with different methods of measurement, including false positives and false negatives, and provide suggestions for practice and research.

The Women in Behavior Analysis Hall of Fame: Description and 2021 Inductees

The inaugural Women in Behavior Analysis Conference (WIBA) was hosted in 2017 to highlight the accomplishments of women in the field of behavior analysis, provide opportunities for early career behavior analysts to obtain mentorship, and encourage meaningful discourse about gender issues in the field. In 2021, WIBA created the Hall of Fame to identify and honor outstanding women who have contributed to the field. Four stellar and important women were inducted into the inaugural class: Eve Segal, Bea Barrett, Martha Bernal, and Judith Favell. This article provides an overview of the structure and function of the hall of fame as well as the individual accomplishments, accolades, and impacts of these women as described in the Hall of Fame induction ceremony. Each year a newly selected group of women will be inducted, and their career will be highlighted in an article in Behavior Analysis in Practice.

Integrative Review of Developmental Behavior-Analytic Concepts

We reviewed five behavior-analytic concepts related to development: behavioral trap, cumulative-hierarchical learning (CHL), basic behavioral repertoire (BBR), pivotal behavior, and behavioral cusp. We searched for terminological variations of the concepts in the CAPES Journals Portal and selected for analysis 31 peer-reviewed articles written in English or Portuguese, published between 1967 and 2021, that contained the search terms in the title, abstract, or keywords and contextualized in the main text. We analysed the conventional usage of the concepts, their conceptual limitations, and the relationships among them, declared or implied, and proposed a conceptual integration of the concepts under a CHL framework, following a path indicated by other authors. We considered BBR, pivotal behavior, and behavioral cusp nonsynonymous concepts of the same logical category, referring to prerequisites for important developmental outcomes and targets of CHL-inspired interventions but defined by different effects on subsequent behavioral development. The three concepts can be conflated in a superset-subset fashion, based on the specificity of their effects: BBR consists of a broad class of behaviors that may affect subsequent learning; the subclass of BBRs characterized by far-reaching collateral effects are classified as pivotal behavior, and the subclass of pivotal behaviors whose potential effects include contact with unprecedented environmental contingencies are classified as behavioral cusps. We propose that behavioral traps be explicitly incorporated in the CHL framework, to emphasize the environmental component of the cumulative-hierarchical learning process. Our formulation seems to organize the conceptual field in a way that respects the conventional use of concepts, preserving their strengths. Regardless of the specific formulation, we believe that integrating the various development-related concepts within a cumulative-hierarchical learning framework can encourage a more proactive integration of findings, questions, and practices informed by each concept, which could lead to the mutual refinement of the corresponding conceptual and methodological frameworks, as well as new research questions and practical applications. In particular, we expect that explicitly incorporating behavioral traps within the CHL framework will provide a useful heuristic model to guide research on how natural environmental contingencies influence the systematic transformation of behavior across the lifespan.

Variables involved in the acquisition and maintenance of racial aggression and its victims' reactions

This study aimed to investigate how behavior analysis can contribute to the understanding of some variables and processes involved in the acquisition and maintenance of racial aggressors' behaviors, as well as the victims' reactions. We describe how the concepts of rule-governed behavior and motivating operations may be involved in institutional racism: Individuals belonging to ethnic groups who hold the social administration in a context may keep important reinforcers available for their own group, while other racial groups may have their access to those reinforcers hindered. For these privileges to be perpetuated, the ruling group can arrange contingencies that reinforce the behavior of following certain rules that contribute to the maintenance of relevant reinforcers for the ruling group and exclusion of Black individuals and other people of color. For those underrepresented groups, motivating operations can be manipulated and reinforcers can be provided only when their responses are deemed appropriate by the dominant group. Individual learning through discriminative training, equivalence class formation, transfer of functions, stimulus generalization, and function altering were also discussed. Patterns such as aggression, escape, and avoidance, were identified in the actions of racial aggressors. Finally, the victim's reactions were also identified as escape, avoidance, or aggression of racial aggressors, but also as effects of processes such as learned helplessness, extinction after elimination of benefits, countercontrol, and respondent conditioning. Despite the lack of research in the field, behavior analysis has the power to elucidate some variables related to this theme, aiding, thus, evidence-based intervention proposals.

Introduction to Teaching the History of Behavior Analysis: Past, Purpose, and Prologue

This article introduces a special section of Perspectives on Behavior Science on teaching the history of behavior analysis. Although behavior is distinctive, behavior analysis is diverse, and the history of behavior analysis is deep, teaching the field's history often is not. The special section offers means for remedying this. The introduction has three sections. First, it relates the genesis of the special section: the 2018 meeting of the Association for Behavior Analysis International and, before that, the 2015 meeting of Cheiron: The International Society for the History of the Behavioral Sciences. Second, it addresses the purposes-reasons and rationales-for teaching history, especially the history of behavior analysis. And third, it offers a prologue for teaching the field's history based on a review of what is taught or not in recent textbooks and handbooks on the field's basic and applied research and their conceptual foundations. In its conclusion, the article previews the section's other articles: (1) three exemplars on how history can be embedded in courses on the field's foregoing three subdisciplines; (2) an exemplar of teaching history in a stand-alone course on the field's history overall; (3) a discussion that addresses how to improve instruction in these courses through narrative methods; and (4) a conclusion about the present and future of teaching the field's history (e.g., giving the history of behavior analysis away).

Teaching the History of Applied Behavior Analysis

Incorporating historical readings and discussion into applied behavior-analytic coursework may be an important strategy for developing well-rounded behavior analysts. However, little guidance is available to instructors interested in teaching the history of applied behavior analysis. This article describes how the history of behavior analysis can be incorporated into a course on applied behavior analysis to achieve this goal. The history of punishment/aversives in behavior analysis will be provided as an example of how the history of behavior analysis can be embedded into applied coursework. The historical interaction between the culture at large (i.e., the culture beyond behavior analysis) and behavior-analytic literature and events related to punishment will be described because both affect the field and have led to the current state of practice. History related to early ethical standards, early experimental analysis of behavior literature, the backlash against early applied behavior analysis, and the field of behavior analysis' response to the backlash is discussed.

Behavioral community psychology in the Amazon rainforest: Suggestions for when behavior analysts meet alterity

The present paper aimed to discuss and interpret methodological issues and contributions arising mainly from professional field work conducted by a behavior analyst working as a behavioral community psychologist in the Amazon rainforest, in northern Brazil. We looked at such a professional's day-to-day circumstances and challenges within a semi-isolated Indigenous community, and systematized impressions and implications for practice with diverse verbal communities and social groups. We believe that looking at experience with those specific social contexts enables us to critically examine behavior analysis community practice more generally. We provided examples of said practices and examined their explicit and more subtle consequences. In light of that, we discussed features of a collaborative methodological stance while working in the field that we wish to foster and encourage. We conclude by pointing out advantages of more in-depth and intensive relational methods for behavior analysts in community practice.

Combined effect of diazepam and polystyrene microplastics on the social behavior of medaka (Oryzias latipes)

The combined effect of microplastics and pharmaceuticals on aquatic organisms is an issue of concern. In this laboratory study, we evaluated the combined effect of polystyrene microplastics (2-μm diameter) and diazepam on the social behavior of medaka (Oryzias latipes) by using the shoaling behavior test with five treatment groups: solvent control, polystyrene microplastics exposure (0.04 mg/L), low-concentration diazepam exposure (0.03 mg/L), high-concentration diazepam exposure (0.3 mg/L), and polystyrene microplastics and low-concentration diazepam co-exposure. After 7 days of exposure, the shoal-leaving behavior of the high-concentration diazepam exposure group (8.9 ± 8.3 counts/medaka) and the co-exposure group (6.8 ± 6.7 counts/medaka) was significantly greater than that in the solvent control group (1.8 ± 2.6 counts/medaka). Even after 5 days of recovery, medaka in the co-exposure group left the shoal more often (7.3 ± 5.0 counts/medaka) than those in the solvent control group (2.6 ± 2.6 counts/medaka), whereas the shoal-leaving behavior in other exposure groups, except for the high-concentration diazepam exposure group, was restored. Our findings show that the combined effects of diazepam and polystyrene microplastics suppressed medaka social behavior, suggesting that the presence of microplastics can enhance the adverse effects of pollutants on the social behavior of aquatic organisms.

Remote Training of Dental Students and Professionals to Promote Cooperative Behavior in Patients with Intellectual and Developmental Disabilities

Many individuals diagnosed with intellectual and developmental disabilities (IDD) are uncooperative during routine dental exams, leading to poor oral health in this population. Few studies have evaluated methodologies for preparing dental students and professionals to work effectively with patients diagnosed with IDD. In this study, experimenters used remote behavioral skills training (BST) to train dental students and professionals how to implement a practical intervention that included tell-show-do, contingent praise, and noncontingent reinforcement. Results suggested that group training conducted via videoconferencing was effective for teaching six of seven participants to implement the intervention in the absence of post-training feedback. This approach appears useful for quickly and efficiently training current and future dental professionals to implement behavior techniques to promote patient compliance.

Cultural Responsiveness Framework in BCBA® Supervision

Behavior analytic supervisees need to master technical and conceptual skills in their fieldwork and training. Recently, the profession has recognized the need for cultural responsiveness to be emphasized and woven throughout clinical practice and supervision. However, findings from research within applied behavior analysis (ABA) yield limited information on specific methods to increase one's cultural responsiveness, as well as few tools to identify areas of development. This paper highlights challenges BCBA®s face in providing culturally responsive supervision. The authors also make recommendations for specific areas of focus in the pursuit of culturally responsive training and skill development through the introduction of the Culturally Responsive Supervision Self-Assessment (CRSS) tool. Cultural constructs that could be addressed using the CRSS tool include, but are not limited to, race, religion, gender conformity, and intersectional paradigms of culture.

Humble Behaviorism Redux

The need to bring behavior analysis to scale is no more obvious or urgent than now. Collaboration between behavior analysts and healthcare workers, educators, policymakers, mental health clinicians, social workers, and so many other professionals is critical to reaching under-resourced and traditionally marginalized populations. First, however, interprofessional collaboration must be adopted widely and reinforced within the behavior analytic community. Disciplinary centrism and hubris pose barriers to effective interprofessional collaboration, leading one to assume the position that practitioners of the same discipline are better trained and smarter than those of a different field. However, cultural humility (Wright, Behavior Analysis in Practice, 12(4), 805-809, 2019) is an alternative to disciplinary centrism that allows professionals to retain identities born of cultural histories and training (Pecukonis, Journal of Teaching in Social Work, 40(3), 211-220, 2020). Furthermore, cultural reciprocity is a process of self-observation and collaborative inquiry that involves questioning one's own assumptions and forces individuals (and professions) to confront the contradictions between their values and their practices (Kalyanpur & Harry, 1999). In this paper, we revisit the call for Humble Behaviorism first made by Alan Neuringer in 1991 and the recommendations of fellow behavior analysts since. Specifically, we introduce a framework of cultural reciprocity to guide humble behaviorists as they acquire behaviors necessary to establish and maintain productive interprofessional relationships. We encourage them to act on their ethical and moral duties to address social problems of global concern and bring behavior analysis to scale.

What's the Big IDEA? A Preliminary Analysis of Behavior Analysts' Self-Reported Training in and Knowledge of Federal Special Education Law

Many behavior analysts currently work in school settings or with individuals who may qualify for educational services through federal special education law. However, it remains unclear what training, if any, behavior analysts receive in this law. Behavior analysts have an ethical responsibility to practice within their scope of competency and in compliance with legal regulations. Thus, it is important to determine whether behavior analysts practicing in the United States are adequately prepared and familiar with federal special education law. The current study consisted of a survey wherein respondents answered questions pertaining to the relevance of federal special education law, their familiarity with core terminology, and the alignment between the law and the Professional and Ethical Compliance Code for Behavior Analysts (Behavior Analyst Certification Board, 2016). Respondents' self-report indicates that behavior analysts hold conflicting views on how federal special education law aligns with and influences their role as service providers. As such, practitioners and agencies alike may benefit from explicit clarification of the responsibility Board Certified Behavior Analysts have to seek training in and adhere to federal special education law.

Stimulus functions of nicotine

Behavioral pharmacology has made vital contributions to the concepts and methods used in tobacco and other drug use research, and is largely responsible for the now generally accepted notion that nicotine is the primary component in tobacco that engenders and maintains tobacco use. One of the most important contributions of behavioral pharmacology to the science of drug use is the notion that drugs can act as environmental stimuli that control behavior in many of the same ways as other stimuli (e.g., visual, gustatory, olfactory). The purpose of this chapter is to provide an overview of research that illustrates the respondent and operant stimulus functions of nicotine, using a contemporary taxonomy of stimulus functions as a general framework. Each function is formally defined and examples from research on the behavioral pharmacology of nicotine are presented. Some of the factors that modulate each function are also discussed. The role of nicotine's stimulus functions in operant and respondent theories of tobacco use is examined and some suggestions for future research are presented. The chapter illustrates how a taxonomy of stimulus functions can guide conceptions of tobacco use and direct research and theory accordingly.

Behavioral Ethics: Ethical Practice Is More Than Memorizing Compliance Codes

Disciplines establish and enforce professional codes of ethics in order to guide ethical and safe practice. Unfortunately, ethical breaches still occur. Interestingly, it is found that breaches are often perpetrated by professionals who are aware of their codes of ethics and believe that they engage in ethical practice. The constructs of behavioral ethics, which are most often discussed in business settings, attempt to explain why ethical professionals sometimes engage in unethical behavior. Although traditionally based on theories of social psychology, the principles underlying behavioral ethics are consistent with behavior analysis. When conceptualized as operant behavior, ethical and unethical decisions are seen as being evoked and maintained by environmental variables. As with all forms of operant behavior, antecedents in the environment can trigger unethical responses, and consequences in the environment can shape future unethical responses. In order to increase ethical practice among professionals, an assessment of the environmental variables that affect behavior needs to be conducted on a situation-by-situation basis. Knowledge of discipline-specific professional codes of ethics is not enough to prevent unethical practice. In the current article, constructs used in behavioral ethics are translated into underlying behavior-analytic principles that are known to shape behavior. How these principles establish and maintain both ethical and unethical behavior is discussed.

Soft Skills: The Case for Compassionate Approaches or How Behavior Analysis Keeps Finding Its Heart

As the field of behavior analysis expands, our need to develop ourselves as more effective collaborators, particularly with families who may be the primary consumers of our science, becomes paramount. As scientists, our training lies primarily in the behavior analytic technologies that we study and apply. But our ability to disseminate our science, collaborate with non-behavior analysts, and ultimately grow our field hinges on our ability to navigate interpersonal situations in a way that puts forth compassion and humanity. We have the opportunity and capability to use our empirical procedures to implement and assess the effectiveness of interventions that target the soft skills of our field. The current article discusses the benefits of empathic and collaborative approaches in fields related to behavior analysis and provides suggestions for current behavior analysts to incorporate compassionate care into their practices. We provide a checklist for compassionate interactions accompanied by possibilities for its use as a tool for self-evaluation, procedural fidelity, and comprehensive training in the area of collaboration with families. Finally, we discuss areas for future research with respect to assessing and improving behavior analysts' compassionate approaches to treatment.

Jack and Me

Although Jack Michael has greatly influenced the field of behavior analysis, very few have had the opportunity to be directly supervised by him. In this article, I share my personal history as one of Jack's last graduate students to illustrate his teaching and mentorship approach. Jack was a caring advisor who has had a long-lasting impact on both my personal life and my professional career.

Probabilistic generative modeling and reinforcement learning extract the intrinsic features of animal behavior

It is one of the ultimate goals of ethology to understand the generative process of animal behavior, and the ability to reproduce and control behavior is an important step in this field. However, it is not easy to achieve this goal in systems with complex and stochastic dynamics such as animal behavior. In this study, we have shown that MDN-RNN,a type of probabilistic deep generative model, is able to reproduce stochastic animal behavior with high accuracy by modeling the behavior of C. elegans. Furthermore, we found that the model learns different dynamics in a disentangled representation as a time-evolving Gaussian mixture. Finally, by combining the model and reinforcement learning, we were able to extract a behavioral policy of goal-directed behavior in silico, and showed that it can be used for regulating the behavior of real animals. This set of methods will be applicable not only to animal behavior but also to broader areas such as neuroscience and robotics.

Brazilian Government Strategies to Protect Women

In 2018, 22,000,000 Brazilian women experienced some type of violence (either physical or psychological), and 42% of these episodes occurred in the domestic environment. Therefore, government strategies have been developed to solve this problem. This study aimed to (a) carry out a survey of Brazilian government strategies for the protection of women after the creation of the Maria da Penha Law (Law No. 11.340, 2006) and (b) discuss these strategies from the concept of cultural design. Sixteen laws, five decrees, and two ordinances were found and analyzed. In a general way, the analysis suggests that they are not effective cultural plans because most do not show long-term results, and some of the laws that typify crimes and those that relate to the aggressor's behavior do not specify the target behaviors, so there is no explicit contingency. Despite this, such strategies are relevant, as they end up providing the protective context for women from a social, legal, and political point of view. Finally, it is expected that the discussions raised in the present work can help prepare interventions that favor socially beneficial cultural practices.

A Systematic Review and Quantitative Analysis of Interteaching

Interteaching is a behavioral teaching method that departs from the traditional lecture format (Boyce & Hineline in BA 25:215-226, 2002). We updated and expanded previous interteaching reviews and conducted a meta-analysis on its effectiveness. Systematic searches identified 38 relevant studies spanning the years 2005-2018. The majority of these studies were conducted in undergraduate face-to-face courses. The most common independent variables were manipulations of the configuration of interteaching or comparisons to traditional-lecture format. The most common dependent variables were quiz or examination scores. Only 24% of all studies implemented at least five of the seven components of interteaching. Prep guides, discussions, record sheets, and frequent assessments were the most commonly implemented. Meta-analyses indicated that interteaching is more effective than traditional lecture or other control conditions, with an overall large effect size. Furthermore, variations in the configuration of the interteaching components do not seem to substantially limit its effectiveness, as long as the discussion component is included. Future research informed by the present review includes: (a) investigating the efficacy of interteaching in additional academic areas, online environments, workplace training, and continuing education, (b) testing alternative outcome measures, generalization, and procedural integrity, (c) conducting systematic component analyses, and (d) measuring social validity from the instructor's perspective.

LINCE PLUS software for systematic observational studies in sports and health

This paper aims to offer a free software program, LINCE PLUS, suitable for systematic observational studies in sports and health, conducted in natural contexts such as training, education or psychology. Using one or several videos simultaneously, different parameters such as behaviors, decision-making or strategies can be analyzed. The software includes several functionalities for studies that researchers need to utilize throughout the observational study process. Collaborative work can be accomplished by using simultaneous videos and multiple observers. The results of all research conducted by LINCE PLUS are offered inside the application in real time, enabling common calculations or including specific analysis with R language without the need for any other external tool. Moreover, LINCE PLUS shows the results of each study with interactive charts or, if needed, it exports the data to specific data analysis software programs (e.g., SAS, Excel, Theme, GSEQ 5, Hoisan). We include examples of sports and health studies that have been conducted with LINCE PLUS to show the suitability of this software program.

Advocating for the Use of Restorative Justice Practices: Examining the Overlap between Restorative Justice and Behavior Analysis

Broadly defined, restorative justice (RJ) is a set of procedures based in Indigenous peacemaking practices that reduces recidivism and guides the effective reparation of harm. RJ practices provide harm-affected parties an opportunity for engagement in the resolution process, which theoretically enhances community well-being. RJ practices overlap significantly with behavior-analytic principles. Implementing RJ practices from a context-focused, appetitive-based approach that focuses on classes of behaviors may address harmful behaviors within police organizations. RJ practices may also facilitate changes in contexts that support behaviors valued by the community. The current review discusses criminal and restorative justice, RJ processes and practices, the effectiveness of RJ in various contexts, how RJ overlaps with behavior-analytic principles and existing behavior science models in general, research suggestions, and recommendations for behavior analysts implementing RJ within police organizations and communities to address officer misconduct.

A Look in the Mirror: How the Field of Behavior Analysis Can become Anti-Racist

Sparked by recent events, discussions of systemic racism and racial inequalities have been pushed to the foreground of our global society, leading to what is being called the largest modern-day civil rights movement (Buchanan et al., 2020). In the past, Black, Indigenous, and People of Color (BIPOC) activists and scholars, among others, have evaluated and critiqued systems and organizations within our society. Nonetheless, it was not until recently that this movement was truly noticed by a greater number of people, some of whom are now further assessing how BIPOC are viewed and treated within their organization and by society as a whole (Worland, 2020). This is not only due to the increase in video evidence (e.g., released body cam footage, social media postings), but also the previous administration's rhetoric and political agenda (Hubler & Bosman, 2021). Police departments, educational institutions, and large companies have, for decades, been under scrutiny for their systems and practices that promote racism, inequality, and inequity. The field of behavior analysis, with its Eurocentric roots and observed lack of diversity, equity, and inclusion, is not exempt from such evaluations. It is time that we take a look in the mirror and evaluate our own professional, research, educational, and clinical practices, and work towards creating a new, more inclusive, field of behavior analysis that promotes anti-racism and cultural humility.

Maintaining Aging Hippocampal Function with Safe and Feasible Shaking Exercise in SAMP10 Mice

INTRODUCTION

The disabling effects of dementia, an incurable disease with little effect on mortality, affect society far more than many other conditions.

OBJECTIVE

The aim of this study was to stop or delay the onset of dementia using low-cost methods such as physical exercise.

METHODS

Senescence-accelerated model-prone (SAMP) 10 mice were made to perform a user-friendly shaking exercise for 25 weeks. The motor function and hippocampal functions (learning, spatial cognition) of the mice were evaluated using behavioral experiments. The degree of hippocampal aging was evaluated based on brain morphology. The association between behavioral performance of the mice and the degree of hippocampal aging was then evaluated.

RESULTS

The behavioral test results showed that the shaking group had higher motor coordination (p < 0.01) and motor learning (p < 0.05). Significantly higher performances in the learning ability were observed in the shaking group at a middle-period experiment (p < 0.05); the spatial cognitive functions also improved (p < 0.05). The shaking group showed delayed ageing of cells in the dentate gyrus (DG; area: p < 0.01) and cornu Ammonis (CA; area: p < 0.01) regions of the hippocampus.

CONCLUSIONS

The shaking exercise enhances the activity of mice and reduces age-associated decreases in learning and spatial cognitive functions. Regarding hippocampal morphology, shaking exercise can prevent non-functional protein accumulation, cell atrophy, and cell loss. Specifically, shaking exercise protects cell growth and regeneration in the DG area and enhances the learning function of the hippocampus. Furthermore, shaking exercise maintained the spatial cognitive function of cells in the CA3 and CA1 regions, and prevented the chronic loss of CA2 transmission that decreased the spatial memory decline in mice.

A Behavior-Analytic Approach to Antivaccination Practices

In recent years, there has been an increase in outbreaks of diseases that are preventable by vaccination. As vaccination involves behavior, behavior analysts are uniquely positioned to contribute solutions to this socially significant problem. The present article explores a behavior-analytic approach to understanding the function of the behavior of both people who have their children vaccinated and those who do not have their children vaccinated, and potential interventions to increase vaccination rates. An introduction to the problem is followed by a brief history of the antivaccination movement. In our analysis, a failure to vaccinate is conceptualized as a noncompliance response (i.e., medical nonadherence), and conditions giving rise to that noncompliance are evaluated. In this process, the roles of avoidance, the functional-altering impact of rule-governed behavior, relational frames, and countercontrol are considered. Potential solutions informed by applied behavior-analytic literature, including contingency management and behavioral safety, are discussed.

Anger, Fear, and Sadness: How Emotions Could Help Us End a Pandemic of Racism

Racism, recently referred to as another kind of pandemic, affects the health and safety of diverse individuals within the United States and around the world. Emotions are a powerful and integral aspect of the experience of racism; however, within the field of behavior analysis, we have been hesitant to acknowledge emotion or explore how it relates to behavior and behavioral contingencies. As a result, the scope of our understanding of emotion is limited. To better understand the current experience and perception of practitioners in the field of behavior analysis, as they relate to emotion and racism, a brief survey was conducted. Findings indicated that although many may be comfortable discussing emotion and displaying emotions for themselves and others, this was not the case for everyone. Further, many were uncomfortable discussing racism. Although participants believed that emotions of racism are important and should be addressed by the field of behavior analysis, they think the field has not done enough work in this area. The results of the study lead to several recommendations, including additional antiracism research and the acknowledgment of emotional experience, as well as for how individuals can better understand, and maybe reduce, the negative emotions associated with oppression.

Cultivating the Ethical Repertoires of Behavior Analysts: Prevention of Common Violations

Violations of the Professional and Ethical Compliance Code for Behavior Analysts occur despite coursework, supervision, and training. In this discussion, we highlight the most common violation categories identified: (a) improper or inadequate supervision/delegation, (b) failure to report/respond to the Behavior Analyst Certification Board (BACB) as required, and (c) professionalism/integrity. The specific areas addressed under supervision/delegation involve behavior analysts' standards and performance as supervisors, as well as compliance with coursework. For failure to report, the focus is on responding, reporting, and providing updated information to the BACB in a timely manner. Finally, the section on professionalism and integrity addresses multiple code elements, including integrity, professionalism, and scientific relationships, as well as methods for promoting an ethical culture and decisions involving ethical violations by others. Importantly, we provide guidance on the structure and organization of supervision, methods and guidelines regarding reporting, and rubrics to shape and evaluate professionalism and integrity. We provide recommendations for the supervision process and for practitioners from the organizational perspective so that the organization supports and promotes an ethical culture.

The Function of the Police Force: A Behavior-Analytic Review of the History of How Policing in America Came to Be

The racial differentiation of policing in America has been widely researched and documented (Walker & Katz, 2008; Wilson & Kelling, 1982). Although these discrepancies are largely documented, there have been few changes within the policies, procedures and laws governing police officers. The results of this are two-fold. First, it has led to the continuation of individual acts of racism of police officers across the country. Second, it has upheld the systemic racism that results in the discrepancies in outcomes between Black people and white people, making it more likely that Black individuals will interact with police officers and have more negative outcomes as a result of these interactions. The reasons for this include lack of data regarding the race of the police officers involved in fatal officer-involved shootings, reliance on self-report of officers regarding instances of excessive force, and lack of accountability of individuals and departments alike. These issues are symptoms of the larger problems of individual and institutionalized racism that not only increases racism within those within the police force, but also increases the likeliness that any police officer will engage in violence against a person of color. To develop effective interventions that will change policing behaviors and the racism observed within the police force, one must first understand the historical development and function of policing and its intersection with both individual and institutional racism. This paper will provide a clear definition of racism followed by a function-based behavior analytic examination of the historical development of policing in America.

On the challenges of cognitive psychopathology research and possible ways forward: Arguments for a pragmatic cognitive approach

Cognitive psychology had a profound impact on psychopathology research. Nevertheless, the fact that cognition cannot be observed or manipulated directly complicates debates about the nature of the mental mechanisms that mediate psychopathology. This is less troublesome for psychopathology researchers who adopt an explicitly pragmatic approach that aims to use cognitive theories as tools for improving psychotherapy than for psychopathology researchers who seek to establish whether those theories are 'correct.' A pragmatic cognitive approach fosters progress by encouraging (a) reality-checks aimed at ending unproductive theoretical debates between cognitive theories, (b) a separation between to-be-explained psychological phenomena and explanatory mental constructs, (c) theoretical diversity, and (d) interactions with behavior analysis.

Impact of County Sociodemographic Factors and State Policy on Geographic Access to Behavior Analysts Among Children with Autism Spectrum Disorder

To examine the relationship between geographic access to Board Certified Behavior Analysts (BCBAs) among children with autism spectrum disorder (ASD) and county sociodemographic factors and state policy, we integrated publicly available data from the U.S. Department of Education’s Civil Rights Data Collection, Behavior Analyst Certification Board’s certificant registry, and U.S. Census. The study sample included U.S. counties and county equivalents (e.g., parishes, independent cities) in 49 states and D.C. (N = 3040). Using GIS software, we assigned BCBAs to counties based on their residence, allocated children via school districts to counties, and generated per-capita children with ASD/BCBA ratios. We distributed counties into five categories based on these ratios: no BCBAs (reference), ≥ 31, 21–30, 11–20, > 0–10. We used a generalized logit model to conduct analyses. Highly affluent and urban counties had the highest access to BCBAs with odds ratio estimates for affluence ranging from 2.26 to 5.26. County-level poverty was positively associated with access, yet this relationship was moderated by urbanicity. Race-ethnicity and healthcare insurance coverage were negatively related to access. Other variables were not significant. Targeting non-urban and less affluent counties for provider recruitment and maintenance could most improve access to BCBAs. In addition to strategies specific to BCBAs for improving geographic access, traditional strategies used for other healthcare providers could be useful.

Orange is the New Asylum: Incarceration of Individuals with Disabilities

Individuals with disabilities and/or mental health concerns were historically removed from society and placed in institutions and asylums. Advocacy groups, drawing on civil rights movements, protested and lobbied for deinstitutionalization and increased inclusion of disabled individuals in schools and communities (Chapman et al., 2014). Although disabled individuals have more rights and access than ever before, they are still segregated in schools, encounter the judicial system more often, and are murdered by police (Reingle Gonzalez et al. in Journal of Disability Policy Studies 27:106-115, 2016). We examine the history and ongoing incarceration of individuals with differences in the United States by analyzing contextual variables, as well as systemic inequities, including the school-to-prison pipeline, access to services, and prison infrastructure. We offer resources and actionable ways for behavior analysts to begin antiracist and anti-disableist work, apply principles of behavior analysis to address personal and systemic racism, and engage in advocacy toward a more just and equitable future for all.

Rules of Conduct for Behavior Analysts in the Presence of Hypothetical Constructs: A Commentary on Eckard and Lattal (2020)

Eckard and Lattal (2020) summarized the behavioristic view of hypothetical constructs and theories, and then, in a novel and timely manner, applied this view to a critique of internal clock models of temporal control. In our three-part commentary, we aim to contribute to the authors' discussion by first expanding upon their view of the positive contributions afforded by constructs and theories. We then refine and question their view of the perils of reifying constructs and assigning them causal properties. Finally, we suggest to behavior analysts four rules of conduct for dealing with mediational theories: tolerate constructs proposed with sufficient reason; consider them seriously, both empirically and conceptually; develop alternative, behavior-analytic models with overlapping empirical domains; and contrast the various models. Through variation and selection, behavioral science will evolve.

Animal Behavior and Learning: Support from Applied Behavior Analysis

Applied behavior analysis (ABA) is a relevant field for veterinarians helping clients whose animals engage in problem behaviors. In ABA, learning is defined as behavior change due to changes in the environment. Changing behavior then requires changes in conditions. Understanding the importance of control and the difference between emotional behavior and emotional feelings also is informed by ABA. Every behavior intervention should start with a systematic, analytical process called a functional assessment. Behavior change strategies are described, including an ethical procedural hierarchy based on the least intrusive, effective behavior change solution.

Free gait in a shallow pool accelerates recovery after exercise in model mice with fibromyalgia

This study aimed to determine the effect of pool gait exercise using fibromyalgia-induced model mice. The sensory threshold, locomotive behavior, electrocardiogram, and onset time after the gait test in shallow water using male C57BL/6J mice (weight, 30–35 g; n=21) were investigated. To induce fibromyalgia in model mice, reserpine was injected intraperitoneally into wild-type mice once a day for 3 days. Subsequently, the fibromyalgia-induced model mice were randomly classified into two groups as follows: the control group (n=11) and the pool gait group (n=10). The mice in the pool gait group walked in the same cage containing shallow warm water 5 times per week. Both groups underwent sensory thresholds and video recordings to determine locomotive behaviors weekly. Further, both heart rate and video recordings for observation of a recovery after the gait test in shallow water were undertaken (control group; n=5, pool gait group; n=5). The pool gait did not affect sensory thresholds and locomotive behavior; however, in the pool gait group, both the recovery after the test, such as onset time and gait distance, were considerably better than those of the control group. Furthermore, changes in heart rate and heart rate irregularity after the test were more apparent in the control group than in the pool gait group. The free gait in a shallow pool accelerated recovery after exercise, unlike the sensory threshold.

Tutorial: Applying Machine Learning in Behavioral Research

Machine-learning algorithms hold promise for revolutionizing how educators and clinicians make decisions. However, researchers in behavior analysis have been slow to adopt this methodology to further develop their understanding of human behavior and improve the application of the science to problems of applied significance. One potential explanation for the scarcity of research is that machine learning is not typically taught as part of training programs in behavior analysis. This tutorial aims to address this barrier by promoting increased research using machine learning in behavior analysis. We present how to apply the random forest, support vector machine, stochastic gradient descent, and k-nearest neighbors algorithms on a small dataset to better identify parents of children with autism who would benefit from a behavior analytic interactive web training. These step-by-step applications should allow researchers to implement machine-learning algorithms with novel research questions and datasets.

Behavior-Analytic Approaches to the Management of Diabetes Mellitus: Current Status and Future Directions

Diabetes mellitus is the seventh leading cause of death in the United States, requiring a series of complex behavior changes that must be sustained for a lifetime (e.g., counting carbohydrates, self-monitoring blood glucose, adjusting insulin). Although complex, all of these tasks involve behavior, making them amenable targets for behavior analysts. In this article, the authors describe interventions that have focused on antecedent, consequent, multicomponent, and alternate procedures for the management of diabetes, highlighting ways in which technology has been used to overcome common barriers to the use of these intensive, evidence-based interventions. Additional variables relevant to poorly managed diabetes (e.g., delay discounting) are also discussed. Future research and practice should focus on harnessing continued advances in information technology while also considering underexplored behavioral technologies for the effective treatment of diabetes, with a focus on identifying sustainable, long-term solutions for maintaining proper diabetes management. Practical implementation of these interventions will depend on having qualified behavior analysts working in integrated primary care settings where the interventions are most likely to be used, which will require interdisciplinary training and collaboration.

When Rules Are Not Enough: Developing Principles to Guide Ethical Conduct

Currently, certified behavior analysts are required to adhere to the ethical rules established by the Behavior Analyst Certification Board® (BACB®) known as the Professional and Ethical Compliance Code for Behavior Analysts (BACB, 2014; hereafter referred to as the BACB Code). Applying these rules without context, however, can result in an overly simplified and mechanistic approach to ethical problem solving. Ethical rules that lack guiding principles may also pose dissemination challenges for behavior analysts tasked with communicating the field's ethical ideals to nonbehavioral colleagues and stakeholders. This article describes the process that our applied behavior analysis organization used to develop a set of guiding ethical principles to supplement the BACB Code. These principles guide our members' ethical decision making and assist them in disseminating our organization's ideals. Following a description of the principle development process, we present our organization's ethical principles and discuss how behavior analysts can use them to make clinical and ethical decisions, and address dissemination challenges.

Using Delay Fading Procedures to Increase Self-Control

Children and adolescents, relative to adults, disproportionately favor smaller, immediate outcomes over larger, delayed outcomes. From a behavioral perspective, this sensitivity toward immediate rewards constitutes impulsive choice, which characterizes numerous behavioral health problems commonly observed during childhood (particularly among individuals with neurobehavioral disabilities). Accordingly, a variety of behavioral technologies have been developed and are widely implemented in applied settings (e.g., self-monitoring programs, interdependent group contingencies, individualized token reinforcement programs) to reduce impulsive responding and promote self-control. Although there is a plethora of research literature detailing these interventions, several promising delay fading procedures may also have clinical utility in applied treatment contexts. The purpose of the present review is to highlight contemporary behavior-analytic research involving delay fading procedures that may increase self-control among children and adolescents and facilitate additional research in the area of self-control.

Risky Business: Increasing Risky Betting Through Rule-Governed Behavior

The present study replicated and extended previous research by exploring the extent to which rules altered participants' engagement in risky betting in an electronic blackjack game. A multiple-baseline across-participants design with predetermined phase changes was used to assess 4 recreational gamblers' betting patterns in blackjack across 3 phases. During baseline, participants played blackjack with no exposure to rules. In the faulty rules phase, researchers gave participants a rule that suggested larger payouts would occur if gamblers played let-it-ride bets. Let-it-ride bets were placed after a winning hand and required participants to wager their entire winnings on the next hand. During the correct rules phase, researchers gave participants a rule that suggested that the let-it-ride bets did not result in larger payouts. Data on let-it-ride bets across each minute of play were collected. The results of the study demonstrated that the frequency of risky bets increased when participants were exposed to the incorrect rule. Following participants' exposure to correct rules, risky bets decreased, but most participants did not return to baseline rates.
