An Analysis of Dependent Contingencies in a Triadic Interaction Using an Exchange Task to Understand Dynamic Concurrent Contingencies under Independent and Reciprocal Conditions

Although behavioral science, due to its emphasis on the use of single-subject research design, appears to focus solely on individual behaviors, behavioral scientists have a long history of lamenting the trajectory of humans, societies, and the discipline itself. Some scholars, for instance, called for our attention to expand our focus beyond individual behaviors to generate solutions for societal issues that we face. When we attempt to develop solutions for issues that require multi-level analysis, we must be cognizant of how institutional contingencies operate at the individual level. The current study analyzed triadic interactions using an exchange task in six triads. The result of this study showed that one common pattern of interactions among participants across triads was direct reciprocation between two participants. The implications of such findings, how they inform social behavior and metacontingency experiments, and future directions are discussed.

Analysis of Sensory Integration Techniques on Automatically Maintained Problem Behavior (open access)

Analysis of Sensory Integration Techniques on Automatically Maintained Problem Behavior

Sensory integration techniques are a common treatment procedure among occupational therapists. The goal is to "apply" input that competes with input from problem behavior. Although this is a commonly recommended intervention, there is limited empirical evaluation with adults with intellectual disabilities. Therefore, we evaluated the effectiveness of occupational therapist-suggested sensory stimuli on the automatically maintained problem behavior of adults. Specifically, we compared the effects of non-contingent access to sensory stimuli and non-contingent access to highly preferred stimuli on the rate of problem behavior. Results suggested that, relative to highly preferred stimuli, sensory stimuli had either a limited effect on problem behavior, or in some cases, were correlated with increases in problem behavior. This suggests that sensory stimuli may not produce the same automatic stimulation as problem behavior. We will discuss implications for treatment, including methods for better identifying stimuli for use in the treatment of automatically maintained problem behavior.

An Assessment and Intervention Model for Establishing Observational Learning During Tact Trials

Observational learning (OL) allows an individual to acquire novel responses by observing others' behavior and the corresponding consequences. The complexity of skills involved with OL may vary with the learning context. A learner may observe modeled responses to both trained (known) and untrained (unknown) stimuli or they may observe both reinforced (correct) and nonreinforced (incorrect) responses. The purpose of this study was to develop assessment and training procedures for OL component skills when the learner observes a combination of learning contexts: reinforced and nonreinforced responses to both trained and untrained stimuli. Two children with autism, Tom and David, participated. We assessed the following component skills in the context of tact trials: (1) Discriminating trained and untrained stimuli, (2) attending to the modeled performance, (3) discriminating consequences, and (4) conditionally responding based upon a name call. Next, we trained the component skill(s) for which the learner's performance did not meet criterion and then reassessed for OL. For both participants, immediate increases in OL were observed; however, modifications to the post-assessment (differential observing response for consequences and/or differential reinforcement) were required to produce (Tom) or maintain (David) criterion levels of responding. Interpretations of these outcomes, as well as limitations and directions for …

An Assessment of Digital Stimulus Prompts to Teach Conditional Discriminations to Children with Autism (open access)

An Assessment of Digital Stimulus Prompts to Teach Conditional Discriminations to Children with Autism

Effective and efficient skill-acquisition procedures must be identified to support individualized behavioral programming for children with autism spectrum disorder (ASD). To do this, practitioners and researchers may use assessment-based instruction. Prompts are a common teaching strategy to promote skill acquisition. The purpose of this applied study was to use assessment-based instruction to evaluate the efficacy and efficiency of within- and extra-stimulus prompts to teach conditional discriminations to two children with ASD. We identified stimulus prompts using a survey of popular children's games and conducted a tablet-based instruction readiness assessment. Stimulus prompts involved motion (within-stimulus) and pointing (extra-stimulus) to evoke correct responses in the presence of a discriminative stimulus. We used an adapted alternating treatments design with a no-treatment control condition to evaluate the effects of both prompt types across multiple sets of stimuli. Both stimulus prompt types were efficacious in facilitating skill acquisition for two of three participants. Little difference was observed in the time to mastery with either prompt. Neither stimulus prompt was efficacious for the third participant. Assessment results will be used to inform clinical programming to teach conditional discriminations to participants and contribute to research on designing and implementing assessments of skill-acquisition procedures.

A Behavior Analytic Account of Humor Responses: Taking a Joke Way Too Seriously (open access)

A Behavior Analytic Account of Humor Responses: Taking a Joke Way Too Seriously

Compared to other examples of human behavior, humor responses have received relatively little attention from the scientific community and by the behavior analytic community in particular. This study investigated what some of the controlling variables for humans to emit a humor response may be. Participants were randomly presented two types of word sequences/jokes: one with a matching punchline and one without a matching punchline. Participants rated whether the jokes were funny or not funny, and reaction time was measured for all stimuli presented. Generally, the results showed that reaction times to punchlines rated as not funny were shorter than punchlines that were rated funny. These differences in reaction time were interpreted with priming, intraverbal control, and multiple control as an experimental foundation. Limitations include the absence of physiological measures due to COVID-19 restrictions and the forced choice of two rating responses. The implications of this research reveal opportunities for future research of humor responses.

Can In-vivo Self-Monitoring Improve Discrete Trial Instruction Implementation? (open access)

Can In-vivo Self-Monitoring Improve Discrete Trial Instruction Implementation?

Beneficial consumer outcomes are most likely when behavior-analytic interventions are implemented with high procedural fidelity (i.e., degree to which the procedure is implemented as intended). Video self-monitoring, which involves teaching staff members to monitor their own procedural fidelity when watching recordings of themselves, can be used to improve and maintain high procedural fidelity, but video self-monitoring requires additional staff time and resources. In-vivo self-monitoring, which involves monitoring procedural fidelity during or immediately following implementing a behavior-analytic intervention, could be a cost-effective option. However, in-vivo self-monitoring needs additional research to understand its effects on procedural fidelity. This current study analyzed the effects of in-vivo self-monitoring on the procedural fidelity of three behavior technicians implementing discrete trial instruction with children with autism. We used a nonconcurrent multiple baseline across participants design to teach participants how to score their procedural fidelity during their discrete trial instruction session. Data suggested that in-vivo self-monitoring was effective for two out of three participants, and those two participants were more likely to be accurate in their self-scored procedural fidelity. Procedural fidelity for the third participant did not increase with in-vivo or video self-monitoring, and the third participant was less likely to be accurate in their self-scored procedural …

Change AGENT Project Part 1: Training Staff to Make Responsive Decisions Based on Goals and Rationales and Evaluating the Effects on the Manding Progress of Children with Autism

When autism interventionists within behavioral intervention programs continually assess the child's behavior and context and adjust their teaching behaviors accordingly, the child can quickly progress towards their goals. While evaluations of flexible behavior-change techniques implemented by experienced clinicians are present in the literature, systematic evaluations of staff training procedures to train interventionists in responsive decision making are lacking. In the current study, flexible training procedures were utilized to not only teach direct-line staff to make decisions based on the learner's behavior, but also to understand and articulate the variables they were responding to. During in vivo training sessions, trainers tailored their use of instructions, modeling, practice, feedback, narration modeling and shaping, and decision-making guidance to the dynamic needs of the staff and child. The effects of the treatment package, which consisted of an in-service training and in vivo training sessions, were measured by observing staff teach vocal manding, which was chosen based on the importance of the skill for the child and because it afforded many opportunities for the staff to learn to make decisions about how to occasion and shape responses. The three children with autism who participated in the study made progress in terms of increasing their frequency …

Change AGENT Project Part 2: Further Analyses of Progress Following Staff Training on Responsive, Goal-Directed, and Rationale-Based Decision Making

Evidence-based practice in ABA is a complex decision-making process involving frequent adjustments in goals and procedures as informed by science, client need, and clinical wisdom. Consistent with the science's foundations, incredible gains are possible for children with autism when practitioners are systematically trained to understand, produce, and be responsive to shifting conditions for change. However, minimal standards for training promote inflexibility and rule following, at the expense of frequent and responsive adjustments. Although research has demonstrated that well-trained staff can effectively implement flexible procedures using in-the-moment assessment and clinical judgment, minimal research has targeted and evaluated the development of these repertoires. Therefore, the purpose of this study was to evaluate the effects of a staff training package, including an in-service training and in vivo training sessions, on staffs' ability to make responsive, goal-directed, and rationale-based decisions directed towards accelerating progress with vocal manding for children with autism. The evaluation was the second part of the larger Change AGENT Project. Results suggested the training was effective at producing socially validated progress across staff and child measures. In essence, the trainer, staff, and child acted as change agents for one another's behavior within the flexible paradigm. Implications, limitations, and future directions are …

Coloniality and the Science of Applied Behavior Analysis

Human life is to be universally cherished and valued. Policies about how to value lives are often developed following gross human rights violations. Some of the most horrific violations have occurred under the guise of biomedical and behavioral research. As a result, policies have been developed to protect participants. Presumably, the primary responsibility of the researcher is their protection. There are, however, potential tensions between protections and research agendas, which set the occasion for over selection of participants with vulnerabilities. This dynamic may establish competing contingencies that devalue, and potentially harm, participants. Power imbalances inherent in the researcher-participant relationship establish the researcher as the dominant knowledge seeking authority and the participant as the subservient subject. Ideally, research in applied behavior analysis is driven by a steadfast orientation toward the enhancement of human life and the amelioration of suffering. The purpose of this paper is to present an analysis of human rights trends in the Journal of Applied Behavior Analysis. The dependent measures are based on ethical principles established for the protection of participants and recommendations concerning participatory research practices in applied behavior analysis. The results indicate that in some cases, protections have been minimally reported. Furthermore, power imbalances are highly …

Comparing a Hear-Say and See-Say Teaching Procedures during Verbal Behavior Instruction

Establishing effective language intervention for those who struggle to acquire it early on has received significant attention from researchers within the field of behavior analysis. The procedures of the present study were adapted from Spurgin' thesis research from 2021, in which a stimulus specific consequence was used during teaching after participants made correct responses. In this case, the stimulus specific consequence was a label for a picture that participants were required to point to during teaching trials. When participants pointed to the correct card, the researcher would label the card and deliver a small wooden block which the participants were told they were working for. In the hear-say procedures, participants were taught one set of cards and instructed to echo the researchers' labels. In the see-say participants were taught a second set of cards and instructed to "beat' the researcher to saying the word. After all cards were taught, were tested with a non-vocal receptive identification test. Immediately following this, participants were tested with a vocal expressive identification test. An extended teaching was included to determine the effects of additional practice within each condition. Results indicated that the participants were able to require some receptive and expressive language but targets …

The Correspondence between Receptive and Expressive Task Performances: A Further Analysis of Necessary Conditions

This study was a replication and an extension of the 2021 research performed by Spurgin and Borquez on the correspondence between receptive and expressive behavior. Spurgin examined the role of the echoic in a hear-say procedure with adult learners, while Borquez examined the role of the echoic in both hear-say and see-say procedures. Both studies found that receptive and expressive correspondence did not occur consistently across participants. The present study asked if the fading steps used during training contributed to the results of the previous researchers. In the present study, the fading steps were changed to minimize the chance that the participant developed a position bias. The conditions were also counterbalanced to analyze the effects of hear-say vs. see-say, easy vs. difficult words, and the order in which the words were trained on the acquisition of receptive labels and the emergence of expressive labels. The study consisted of five phases: pre-training, hear-say teaching, see-say teaching, receptive testing, and expressive testing. Results indicated that although that acquisition of receptive labels improved, the change in fading steps did not make a significant difference in the correspondence of receptive and expressive language. Results showed similar correspondence in the hear-say and see-say procedures. Easy …

Cultivating Liberation: The Effects of Collective Shaping on Context and Power Dynamics within Social Justice Narratives

Social issues are becoming increasingly apparent. More people are experiencing the impact of social issues directly and through their media consumption. It is important to understand and reflect on our collective impact on the media and how the media affects the collective. The purpose of the present study was to evaluate the effects of a collaborative workshop (collective shaping) and a verbal community that examined media depictions of social justice and injustice related to context and power dynamics. The effects of the workshop were evaluated using an A-B design with multiple probe measures across three participants. During the pre-, probe, and post-training assessments, participants watched videos and responded to a written prompt. Results of the study suggest that written responses were not adequately trained during the workshop. However, anecdotally, participant's verbal responding shifted drastically during the training workshop. The results are discussed within the context of the training apparatus, effects the workshop had on the participants and researchers, and progression forward.

Cultivating Liberation within a Verbal Community: Evaluating the Effects of Collective Shaping on Written Narratives and Reflective Statements about Social Issues

The purpose of this study was to evaluate the effects that a training workshop and collective shaping had on the reflective statements and feeling and emotion labels in a written response to videos relating to social issues. The workshop included a presentation interspersed with videos to help practice dialoguing and guide discussion toward generating discourse for social change. The effects of the workshop were evaluated using a single subject A – B design with multiple probe measures across three participants. Participants were given a prompt to write a descriptive narrative in response to a video clip, creating a permanent product for quantitative and qualitative analyses. The study resulted in slight increasing trends for both reflective statements and feeling and emotion labels for Participants 1 and 2. Further analyses show that Participant 3, despite showing little change across reflective statements and feeling and emotion labels, showed significant increase and more stability in the percentage of total words within reflective statements. The results of the workshop are discussed in the context of future research, including the role of social issues in our everyday language and how that affects us at a personal level.

Designing, Implementing, and Evaluating an Online Instructional Program to Teach Students to Evaluate Systemic Social Issues Using a Matrix Analysis

This research aimed to determine the effects of an online training program on the accurate articulation of the concepts and elements needed to conduct a matrix analysis, the accuracy with which participants embedded these elements in a matrix analysis diagram, and the qualitative value of those elements. The development of the online training program was completed through a series of recursive steps. First, four literature searches regarding the matrix analysis, its foundational concepts, and underlying theoretical frameworks; systems analysis; culturo-behavior science; behavior analytic approaches to education; wicked and super wicked problems; and behavioral community psychology were conducted. Second, a tentative list of definitions for each element that collectively forms a matrix analysis was formed used to complete a component-composite analysis for each of the elements, and to determine the component skills individuals would need to develop to complete a matrix analysis and corresponding diagram. The component-composite analysis served as the basis for the general outline of the training program and the structure for the development of the training program presentations, activities, and assessments using Google Classroom. The online training program was piloted with 17 individuals enrolled in a graduate level course on behavioral systems analysis. Following the pilot of the …

Development and Disruption of Collateral Behavior and DRL Performances: A PORTL Exploration (open access)

Development and Disruption of Collateral Behavior and DRL Performances: A PORTL Exploration

One schedule of reinforcement that is used to decrease the rate of a target behavior is differential reinforcement of low rates (DRL). During this schedule, reinforcement is delivered for a target response if it occurs after a certain amount of time has passed since the last instance of this target response. The current study used a table-top game called PORTL and college student participants to investigate how collateral patterns develop and are disrupted during DRL schedules. After the participant developed a collateral pattern of behaviors with the objects, the researcher removed one of the objects that was part of the pattern and waited for a new pattern of behaviors to develop. Once the participant developed a new collateral pattern, the researcher removed a second object. This continued until there was only one object present. Results showed that the rate of reinforcement decreased following the removal of each object, then slowly increased as a new pattern developed.

Discriminative Control of Behavioral Variability in Video Game Play (open access)

Discriminative Control of Behavioral Variability in Video Game Play

Creativity can be a useful skill in today's classrooms and workplaces. When individuals talk about creativity, it's unclear what the controlling variables are when we tact behavior as "creative." Research in understanding the processes behind behaviors that are considered "creative" would assist in identifying functional relations and provide insight on how to teach creativity. Since creativity is often described as doing something different from the norm, behavioral variability may be a potential aspect of creativity. This study aimed to replicate previous findings by investigating the effects of discrimination training in a multiple schedule of varied and repetitive responding in the context of a video game. Participants played through a 2D online video game made in Bloxels. Different alternating-colored platforms served as the discriminative stimuli for the vary and repeat components. Three parameters of variability were measured (e.g., left jumps, right jumps, and double jumps). The results of the study indicate that participants were able to learn the discrimination of when to repeat and vary their responses depending on which colored platform they encountered.

The Effects of a Contingent S-Delta

This thesis attempted a cross-species replication of Bland, et. al., 2018. Human participants went through a computerized, automated shaping procedure that trained them to click on and discriminate between a blue square (SD) and red square (S-delta) on a VR 12 schedule of reinforcement. Three conditions were then presented to the participants consisting of a baseline, punishment, and control condition. In the punishment and control conditions, the SD was replaced by the S-delta or a novel stimulus respectively for 1-second on a VR 5 schedule. With each click, the reaction time and specific object clicked on were recorded. While the present study partially replicated the effect seen in earlier research, our results suggest that, depending on the lens of analysis used, either a punishment or an extinction effect may be causing the results seen.

The Effects of Implementing a Reward-Based Version of Ostrom's Eight Design Principles as an Intervention Package on Responses in a Common Pool Resource (CPR) Game (open access)

The Effects of Implementing a Reward-Based Version of Ostrom's Eight Design Principles as an Intervention Package on Responses in a Common Pool Resource (CPR) Game

The aim of behavior analysis has always been to apply technologies rooted in basic behavioral principles to problems of societal importance (e.g., Skinner, 1948; 1953; 1987). One such problem is the Tragedy of the Commons - a phenomenon arising from systemic failures among a community, leading to the total collapse of a critical resource (Hardin, 1968). Elinor Ostrom's Eight Design Principles were developed to provide a framework for the self-management of common pool resources (CPRs; Ostrom, 1990/2015). When applied as an independently manipulated variable, Ostrom's design principles have shown strong effects in the management of CPRs within the context of a tabletop board game Catan® (Smith & Becker, 2023). This preparation included both rewards (i.e., positive reinforcement) and sanctions (i.e., positive punishment) as a feature of the independent variable. However, it has been well documented that punishing and coercive contingencies can lead to problematic outcomes for individuals and societies (e.g., Sidman, 2001; Skinner, 1976). This study evaluated the effects of utilizing only rewarding consequences in lieu of sanctions in an effort to produce the previously observed control over self-management of a CPR, utilizing the previously adapted rules of the Catan® board game.

The Effects of Instructions on Schedule Sensitivity (open access)

The Effects of Instructions on Schedule Sensitivity

There are many situations in which human performances appear insensitive to changing contingencies of reinforcement when compared to nonhuman operant performances. Explanations of these discrepancies have appealed to rule-governance and have provided some evidence that instructions produce these differences by restricting response alternatives as well as functioning as discriminative stimuli for other contingencies. In order to further evaluate these potential functions, a canonical study on rule-governance was systematically replicated. Five undergraduate participants were tasked with earning blocks by pressing a button during LED-signaled, fixed-ratio 7 and differential-reinforcement-of-low-rate 5-s schedules of reinforcement. Phase 1 of the experiment switched between these two schedules, with the schedule alternating every 1 minute. Phase 2 added instructions to "Go Fast" and "Go Slow" to the LEDs and programmed the lit LED to switch 30 seconds into each 1-minute session. Phase 3 removed the instructions from the LEDs and returned to the procedures of phase 1, with only one LED lit during each 1-minute session. Results showed that instructions influence the response rates as well as stimulus control over those rates. Results also showed that all participants ignored instructions conflicting with the reinforceable rate by the end of Phase 2. These findings indicate that instances of …

The Effects of Prompts on Variability in Children with ASD

The concept of "creativity" has been studied under the perspective of variability in behavior analysis. Creativity and variable responding contributes to problem solving in novel situations, learning new responses in different environments, and promote interactions that would otherwise be prohibited by repetitive behaviors and routines. During childhood, play contributes to the emergence of creativity and variability. Children develop many skills that are important to their lives while engaging in play behaviors. Some of those skills include self-advocacy, communication, and problem solving. Researchers have investigated different methods to promote variable play skills in children with autism spectrum disorder (ASD). There is limited research on prompting as an isolated variable in increasing variability in play responses. The purpose of this study was to investigate the effects of prompting on variable play skills. Results indicated that verbal instructions and modeling were effective in increasing variable play responses. Both participants displayed a sustained increase in novel item engagement when exposed to prompting.

The Effects of Skilled Dialogue Simulation Coaching on the Collaborative Verbal Behavior of Behavior Analysts in Training

Despite the evidence that supports the benefits of a holistic, collaborative approach to autism intervention, but there is little training to teach those skills to professionals. Behavior analysts working in applied settings will often partner with different individuals from very different backgrounds and disciplines. Skilled Dialogue has been recommended as an approach to conversations that values everyone's contributions in fostering compassionate, collaborative, and culturally responsive care to benefit the children served. The purpose of this study was to evaluate the effects of a training workshop to teach the concept and strategies of skilled dialogue to behavior analysts in training. The participants were taught and practiced using the six strategies of Skilled Dialogue: welcoming, allowing, sense-making, appreciating, joining, and harmonizing through use of instructions, rationales, activities, simulations, and feedback. The success of the training was evaluated using a multiple baseline design across training components. Audio and video responses to role-play scenarios were recorded, transcribed, and scored to measure the results of the training workshop on communication skills.

The Effects of Skilled Dialogue Training on Behavior Analysts' Verbal Behavior Related to the Provision of Compassionate, Collaborative, and Culturally Responsive Care

Despite the growing recognition of the importance of compassionate, collaborative, and culturally responsive care in behavior analysis, the training programs to develop relevant skills are meager. The purpose of the current study is to evaluate the effectiveness of Skilled Dialogue training for behavior analysts in improving the use of six strategies–welcoming, allowing, sense-making, appreciating, joining, harmonizing–when engaging in conversations with clients, colleagues and other professionals.

The Effects of Specific and Disguised Mands on Staff's Reinforcer Delivery (open access)

The Effects of Specific and Disguised Mands on Staff's Reinforcer Delivery

Residential facilities for adults with developmental disabilities offer essential accommodations and support services, with fostering communication for residents as an important aspect of care. Despite the importance of communication, previous research has identified concerns about staff performance (SP) in facilitating positive social interactions, such as engaging in consequent-mediating behavior for residents' mands. Previous research has primarily focused on improving SP through skills-based training. Yet, Skinner's theory of verbal behavior emphasizes the social and reciprocal nature of mands. Skinner suggests that the listener's behavior, engaging in consequence-mediating behavior, must be conditioned by the verbal community. However, empirical investigations into the reinforcing practices of staff in residential facilities, such as the shaping and sustaining of different types of resident mands, is limited. The current investigation sought to address this gap in research by evaluating if distinct mand topographies, disguised or specific mands, influenced the likelihood of staff engaging in consequence-mediated behavior across three staff-resident dyads. Results suggest a low probability of staff responding to, or reinforcing, mands, thus limiting conclusions on the effects of mand topographies on staff performance. Future directions and considerations regarding resident-staff interactions are discussed.

The Effects of Using Arbitrary Symbols in Naming Procedures with Adults (open access)

The Effects of Using Arbitrary Symbols in Naming Procedures with Adults

Naming refers to encountering a new word and subsequently being able to use it both expressively and receptively. Sometimes, this can happen in as little as a single experience. Several recent studies have explored factors that influence the acquisition of naming in adults. However, these studies used familiar stimuli for which the participants already had names. In these studies, preexisting stimulus-response relations with the stimuli could have impeded the acquisition of new names for some participants. In contrast, the present study used unfamiliar ("arbitrary") stimuli. In addition, an equivalence test was used to validate the findings because some theorists have claimed that naming is required for equivalence. The results revealed some advantages to teaching naming with arbitrary stimuli. Interestingly, a subset of participants had high scores on equivalence tests without having high scores on expressive tests. This indicates that, contrary to naming theory, naming may not be necessary for equivalence and match-to-sample tests may not be the best test of equivalence. These findings support the independence of the expressive and receptive repertoires both in the development of naming and equivalence.
