Establishing Foundational Nonarbitrary Distinctive and Categorical Relational Responding in Children with Autism.

The present study sought to evaluate a sequence of training procedures on the emergence of foundational relational responses that underly more complex distinctive (i.e., difference) and hierarchical (i.e., categorical) relational frames. In a multiple baseline design, an initial baseline period with three children with autism showed that the participants did not select nonidentical stimuli from an array when presented the contextual cue "different." Simple discrimination training was efficacious in establishing this response and the skill transferred to a novel set of stimuli without reinforcement. In a second baseline period, participants did not demonstrate conditional identical/nonidentical relational responses when provided the contextual cues "same" and "different." Conditional discrimination training with all three participants was again efficacious in establishing the conditional reflexive and distinctive responses and the skill transferred to untrained stimuli. In a third baseline period, participants did not demonstrate correct conditional categorization/sorting. Like in the prior two training conditions, training was efficacious in establishing the target response with a generalized transfer to untrained stimuli.

Top-Down Attentional Processing and Relational Density Evident in Word Search Performance of Children.

Relational frame theory and extensions (e.g., relational density theory; Belisle & Dixon, 2020a, 2020b) provides a behavioral model for top-down attentional processing, where attention is oriented in terms of arbitrarily applicable verbal relations through the transformation of stimulus function. Children's games may provide a strategy for testing transformations of stimulus function when developing new language skills, such as when working with children with autism. Three children with autism underwent relational training to establish lean and dense arbitrary classes. Prior-to relational training, participants were more likely to locate familiar words over unfamiliar words within a word-search task. Following relational training, participants were more likely to locate words that participated in high-density relational classes over neutral or low-density relational classes. These results support the use of common games to supplement relational training with children with autism and provide evidence that top-down attentional processing may involve transformations of stimulus function and can be predicted and influenced through relational training to establish high-density relational classes.

An Examination of the Intervention-Enhancing Effect of Acceptance and Commitment Therapy-Based Training on Direct Service Professionals' Performance in the Workplace.

Direct service professionals (DSPs) provide treatment to individuals with developmental disabilities; however, high levels of performance are not always prevalent among these professionals. The present study examined the effect of an intervention package with verbal and written performance feedback and a performance-based lottery alone as part of a treatment package including an acceptance and commitment therapy (ACT)-based training program on the frequency and technical competence of active treatment for individuals with disabilities provided by DSPs. Both intervention groups performed significantly better than the control group on all observational measures (p < .05). The performance enhancement intervention (PEI) plus ACT group outperformed the PEI group significantly in frequency of active treatment at posttest (p < .05). Self-reported levels of psychological flexibility, workplace stress, and job satisfaction remained stable for all three groups from pre- to posttest despite the increased performance among DSPs in the two intervention groups.

Relational Behavior and ACT: A Dynamic Relationship.

Acceptance and commitment therapy (ACT) and its counterpart, relational frame theory (RFT), represent emerging areas of research and professional interest for behavior analysts. We extend traditional RFT approaches by emphasizing relational framing as a dynamic pattern of behavior with implications for ACT-based strategies implemented by behavior analysts in practice and in research. We borrow from emerging approaches within affective dynamics, relational density theory, and the hyper-dimensional multilevel model to develop some immediate considerations for practitioners. We then extend an approach grounded in relational dynamics to the six core processes of the ACT hexaflex not only to influence negative affective patterns of relational behavior but also to promote greater psychological flexibility and well-being. Finally, we turn this account inward to discuss our own rigidity as a field and the necessity to engage more flexibly with our own science, ultimately to improve the lives of clients whom we serve.

A Large-Scale Naturalistic Evaluation of the AIM Curriculum in a Public-School Setting.

This study evaluated the effectiveness of the AIM curriculum when implemented in a public-school setting by schoolteachers and direct care staff. Three hundred eighteen students took part in this quasiexperimental design where all received the AIM curriculum every day for an entire school year. The participants completed a series of self-assessments (the Avoidance and Fusion Questionnaire for Youth, the Child and Adolescent Mindfulness Measure, and the Strength and Difficulties Questionnaire) at the onset of the study and at the end of the school year to assess psychological flexibility, mindfulness, and emotional behavioral skills. Results suggest that at the end of the school year, participants increased psychological flexibility and mindfulness. State standardized testing scores also showed increases school-wide as compared to the previous 2 years. These results suggest that the AIM curriculum may be effective in large school settings, appeared easy to implement by school staff to address the needs of both the individual student and the entire student body, and likely participated in improving school-wide academic success.

Using Relational Training to Improve Performance During Acceptance and Commitment Training Sessions.

The current study investigated the effect of relational training on improving engagement during acceptance and commitment training (ACT) sessions that aimed to reduce maladaptive behavior. Three female children diagnosed with autism participated in the current research. The relational training protocol involved eight programs designed to improve participants' ability to engage in relational responding. A concurrent multiple-baseline across-participants design was used, and participants' maladaptive behavior during ACT sessions was recorded. Results indicated a decrease in maladaptive behavior for one of the three participants, with a medium to large treatment effect. A secondary measure also showed improvement in all three participants' performance during ACT sessions. The percentage of nonoverlapping data and Cohen's d suggest a small to moderate treatment effect. Implications for implementing ACT with individuals diagnosed with autism are discussed.

Utilizing the AIM Curriculum to Improve Job Performance in an Educational Setting for Children With Autism and Related Disabilities.

The current study evaluated the effect of brief, daily present moment awareness activities on the work performance of paraprofessionals working at a school for children with disabilities. A nonconcurrent multiple-baseline design across three participants evaluated changes in staff-initiated interactions with students and staff's accuracy of data collection on student behavior. Relative to baseline, participants demonstrated an average increase in staff-initiated interactions and an increase in the average percentage accuracy of data collection. Participants averaged 10.02 (range 3.4-16.67) staff-initiated interactions during baseline and 15.38 (range 9.75-24.4) during the intervention phase. Relative to baseline, two of the three participants demonstrated an increase in their average accuracy of data collection on student behavior. Participants' average data collection accuracy was 56.9% (range 40%-86.67%) during baseline and 91.98% (range 86.41%-100%) during intervention. The average percentage of nonoverlapping data was 61.67% (range 25%-100%) for staff-initiated interactions and 33.33% (range 0%-100%) for data collection accuracy. Implications and possibilities for future research related to acceptance and commitment training interventions in workplace environments are discussed.

Transformation of Hierarchical Multiply Controlled Verbal Relations in Children With Autism in a Game of I Spy.

We evaluated the development of mutually entailed arbitrary hierarchical relations and associated transformations of stimulus function across 3 children with autism in a game of I Spy. Top-down hierarchical relational training was efficacious in establishing 4 relational categories (A) containing a total of 5 stimuli (B), where 3 of the stimuli were contained in 2 different categories. Following relational training, all participants demonstrated a transformation of function by identifying the stimuli when provided a multiple verbal stimulus with two category names during I Spy. The procedures were adapted from the PEAK Relational Training System.

Effectiveness of Environmental Manipulation to Enhance Engagement and Ecological Validity at an Agency Serving Individuals With Autism Spectrum Disorder and Other Disabilities.

The ecological validity of interventions can be enhanced when we first consider the environment in which our students participate. Antecedent interventions such as environmental manipulations can be easily and effectively implemented to enhance student engagement and decrease challenging behaviors in classrooms. The current study explored the use of a measurement system developed for widespread use within a school for students with autism spectrum disorder that helped to inform a classroom-wide environmental manipulation in the form of classroom arrangements. Baseline data across three classrooms suggested high, variable rates of challenging behavior and low rates of engagement with staff and materials. After the introduction of the antecedent intervention, engagement increased and challenging behavior decreased. Helping practitioners develop environmental and systems changes may help to complement individual behavior intervention plans.

Evidence From Children with Autism that Derived Relational Responding is a Generalized Operant.

We conducted an empirical examination of derived relational responding as a generalized operant and concurrently evaluated the validity and efficacy of program items contained in the Promoting the Emergence of Advanced Knowledge - Equivalence (PEAK-E) curriculum. A first study utilized a multiple-baseline across-skills experimental arrangement to determine the efficacy of equivalence-based instruction guided by PEAK-E, replicated across 11 children with autism. A total of 33 individualized skills were taught, and the subsequent emergence of untrained relations was tested throughout the investigation. The mastery criterion was achieved for 29 of the 33 instructional targets. Additionally, for 3 participants, results were again replicated with a novel set of stimuli. A second study evaluated the degree to which multiple-exemplar equivalence-based instruction led to the emergence of derived relational responding as a generalized operant. The organized nature of the PEAK curriculum allowed the impact on derived relational responding to be compared to that produced by earlier PEAK models that are focused on the direct training of traditional verbal operants. PEAK-E instruction was introduced in a multiple-baseline design across two participants, with a third staying in a training baseline throughout. Increases in derived relational responding using novel, untrained stimuli were only observed when multiple-exemplar equivalence-based instruction was introduced. Taken together, these results provide support for derived relational responding as a generalized operant and demonstrate the utility of conducting larger scale evaluations of higher order behavioral phenomena in single-case experimental arrangements.

Selection by consequence: A response to Hayes and Fryling (2019).

The paper by Hayes and Fryling (2019) seeks to inform readers that the Kantorian system of Interbehaviorism has been misunderstood and misrepresented by contextual behavior scientists. Furthermore, these authors suggest that much is to be gained by embracing the system developed by Kantor, most importantly that being large scale system building efforts. We disagree with this position, and find the Kantorian system to be of questionable relevancy and at risk of potential extinction within the behavioral community. We also have concerns that perhaps the insights provided by Hayes and Fryling will fail in recruitment of additional members to the Interbehavioral cause. Although the overarching theme of Interbehaviorism is present within emerging dynamical approaches to behavior science, adopting the vernacular of Kantor may be unnecessary to continue his tradition. We recommend allowing empirical selection to run its course in determining the eventual fate of Kantor's Interbehaviorism.

Developing and Enhancing Adherence to a Telehealth ABA Parent Training Curriculum for Caregivers of Children with Autism.

The current COVID-19 pandemic poses unique challenges to the delivery of applied behavior analysis (ABA) services, and there has been a growing demand for evidence-based practices on how to develop a telehealth ABA service model. The current article provides a detailed technological guide on how to develop a telehealth ABA parent training curriculum. Our model also includes a series of brief acceptance and commitment training (ACT) protocols to enhance parental adherence. We provide the details for replicating our telehealth model and also demonstrate its effectiveness. To begin, a step-by-step guide on how to develop this curriculum is presented, as well as protocols used in a 60-day telehealth ABA parent training program. Afterward, we describe a randomized controlled trial design to examine the effectiveness of this protocol. Thirteen families from the southern Illinois region participated in the curriculum before the COVID-19 outbreak. Obtained data indicated training was effective to teach skills, and parents with supplemental ACT material made significantly more progress than those in the control group, t(11) = 2.36, p = .038. Halfway through the training, the outbreak of COVID-19 occurred, and parents in the ACT group were more likely to continue the program, whereas parents in the control group were significantly more likely to postpone their participation, χ2 = 6.96, p = .008. Social validity measures indicated that parents rated the curriculum favorably. Limitations and suggestions for practitioners are discussed.

Generalized Reflexive Responding and Cross-Modal Tactile Transfer of Stimulus Function in Children with Autism.

We sought to evaluate the efficacy of successive matching training for establishing generalized reflexive matching across 4 children with autism. In Experiment 1, differential reinforcement with delay fading was efficacious in establishing "yes" and "no" matching and nonmatching responses in 2 participants when 2 identical or nonidentical picture stimuli were presented. In addition, emergent visual-visual reflexive relational responses were observed using novel picture stimuli in a transfer test phase. In Experiment 2, differential reinforcement alone was efficacious in establishing matching and nonmatching responses in the other 2 participants when 2 identical or nonidentical objects were presented. Transfer to identical objects presented through touch (i.e., tactile discrimination) was additionally observed for both participants. Procedures in the study were adapted from the PEAK Relational Training System to aid in clinical replication, and the translational results have implications for language training with individuals with autism.

Relational Density Theory: Nonlinearity of Equivalence Relating Examined through Higher-Order Volumetric-Mass-Density.

We propose relational density theory, as an integration of stimulus equivalence and behavioral momentum theory, to predict the nonlinearity of equivalence responding of verbal humans. Consistent with Newtonian classical mechanics, the theory posits that equivalence networks will demonstrate the higher order properties of density, volume, and mass. That is, networks containing more relations (volume) that are stronger (density) will be more resistant to change (i.e., contain greater mass; mass = volume * density). Data from several equivalence experiments that are not easily interpreted through existing accounts are described in terms of the theory, generating predictable results in most cases. In addition, we put forward the higher-order properties of relational acceleration and gravity, which follow directly from the theory and may inspire future researchers to evaluate the seemingly self-organizing nature of human cognition. Finally, we conclude by describing avenues for real-world translation, considering past research interpreted through relational density theory, and call for basic experimental research to validate and extend core theoretical assumptions.

Behavior and Substance Addictions in Children: A Behavioral Model and Potential Solutions.

Behavior and substance use addictions are increasingly prevalent in children with increased risk for substance abuse and mental health diagnoses in adulthood. This article proposes a comprehensive model of addiction to inform research on the prevention and treatment of childhood addiction, emphasizing skills training, mindfulness training, and broader treatment strategies consistent with acceptance and commitment therapy.

Intervention Enhancing Effects of Acceptance and Commitment Training on Performance Feedback for Direct Support Professional Work Performance, Stress, and Job Satisfaction.

Direct service professionals (DSPs) provide the majority of treatment to individuals with developmental disabilities in community and residential settings; however, their ability to implement high-quality care is often limited by workplace factors and stress. The present study examined the effect of a verbal and written performance feedback intervention and the addition of an acceptance and commitment therapy (ACT)-based training program on the frequency and technical competence of active treatment provided by DSPs using a multiple-baseline design across 5 participants. Each participant demonstrated an increase in active treatment and technical performance following the implementation of both feedback-only and feedback plus ACT training interventions. Self-reported levels of psychological flexibility, workplace stress, and job satisfaction remained relatively stable for all participants from baseline to intervention despite the increased performance of the DSPs. Implications of the inclusion of an ACT-based training program with traditional behavior-analytic workplace interventions are discussed.

Evaluating the Emergence of the Transformation of Stimulus Function through Representational Drawing in Children with Autism.

The present study aimed to evaluate the utility of representational drawing as an alternative to selection-based responses for evaluating the emergence of the transformation of stimulus function. Two children with autism were initially taught relations among pictures, arbitrary symbols, and arbitrary words. Nonreinforced tests were also conducted to evaluate the possibility of a transformation of stimulus function across stimuli when presented with a generative drawing task. The results suggested that both participants responded at high accuracy following initial training and also were able to transform the functions of these training stimuli such that novel drawings that were never reinforced actually emerged under extinction conditions. These data add to the body of literature supporting the utility of exposing children with autism to applied behavior-analytic interventions that incorporate derived relational responding as a target operant, and this generalized operant also is capable of a transformation of stimulus function.

Establishing Multiple-Control Responding of Children with Autism to People and Emotions in Context by Utilizing Derived Stimulus Relations.

This study evaluated the efficacy of a set of procedures in evoking responding under multiple stimulus control (identifying emotions when provided a person and context) in a match-to-sample arrangement. Three participants with autism achieved a mastery criterion following direct training of the target relations, and two of the participants additionally demonstrated derived relations without direct training (identifying people when provided an emotion and context). Corrective procedures were effective in promoting the emergence of derived relations for the third participant. These data suggest that incorporating derived stimulus relation training and testing procedures may have utility for clinical interventions in children with autism.

Teaching Children with Autism to Tact the Private Events of Others.

We evaluated the efficacy of a most-to-least intrusive error-correction/prompting procedure for teaching 3 children with autism to tact the private events of others through publicly accompanying stimuli. Participants did not reliably demonstrate correct tact responses to publicly observable stimuli that accompany common emotions reported by others (e.g., bandage = hurt) in baseline. Procedures were taken from the Promoting the Emergence of Advanced Knowledge Relational Training System: Direct Training Module (PEAK-DT) to aid in clinical replication, and training was introduced in a multiple-baseline design. Results showed that the procedures were efficacious in teaching this skill to each of the participants, and fast rates of acquisition were observed.
