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. While one participant's verbal responses in all six strategies during the role plays improved after the training, the other participant showed mixed results. High variability in both participants' data suggests that the effectiveness of the training can be better evaluated with tighter control of the components of the training and the measurement system. The potential ways to improve the experimental control in future studies are discussed.

Approximately 50% of individuals who undergo total knee arthroplasty (TKA) fail to achieve a full functional recovery. Current physical therapy practices commonly utilize neuromuscular electrical stimulation (NMES) to passively activate quadriceps muscles. This passive approach does not directly reteach the lost response, but can strengthen the atrophied muscle. Study 1 compared surface electromyography with biofeedback (sEMGBF) with a changing criterion design to NMES alone. Study 2 compared static sEMGBF to NMES with feedback. Study 3 compared surface electromyography (sEMG) with instructions only to NMES. All other methods were constant across the three studies, where I compared the passive and active approach within-subject, across knees, and across groups while controlling for condition order and leg dominance. Each participant receives both NMES and the shaping procedure. Each condition lasts five minutes and consists of 30 muscle contractions. Each contraction lasts 5 seconds and was followed by a 5 second rest. I compared pre and post adapted maximal voluntary isometric contraction (A-MVIC) tests to determine the effectiveness of each condition. Results of the three studies demonstrated that actively teaching voluntary vastus medialis oblique (VMO) engagement using sEMG is more effective than NMES at increasing maximum voluntary isometric contractions of the VMO.

An important predictor of the success of a peer-mentoring program is the quality of the relationship between the peer mentor and the mentee. A previous study identified target outcomes, operationally defined target behaviors, and developed a computer-based instruction (CBI) training module to teach peer mentors relationship skills. The previous study suggested that the CBI training module increased target behaviors in pre-and post-tests that were typed. The current study replicated and extended the previous study with additional participants and analyzed responding during a video-chat generalization assessment. We observed an increase in target behaviors during the CBI post-test for 7 out of 8 modules across two participants and an increase in target behaviors for 5 out of 12 target behaviors across three participants for the generalization assessment. Results suggest that the CBI training modules may be an effective way to teach behaviors that contribute to a high-quality relationship when participants engage in typed responses. However, the extent to which these behaviors generalize to a video-chat generalization assessment may need further research.

Extensive speech on preferred conversation topics may limit conversations with others. For individuals with ASD, extensive speech on a topic may be a form of restricted or repetitive behavior that may be addressed through skill building. However, previous research suggests that skill building may not be necessary if the behavior is sensitive to differential reinforcement contingencies. To evaluate the effects of differential reinforcement in the form of attention on conversation topics, we replicated the results of Stocco et al. by assessing sensitivity to conversational attention with participant-only topic initiations. Additionally, we extended the procedures by evaluating the effects of topic initiations from the participant and the experimenter (shared initiations). Similar to previous research, our results yielded that speech was sensitive to conversational attention across all participants. That is, differential reinforcement contingencies altered levels of speech on topics of conversation, indicating that differential reinforcement procedures may be sufficient in addressing performance deficits. Lastly, we assessed participant preference for participant-only initiation or shared initiation conversations.

One goal of this study was to evaluate the emergence of mands and intraverbals following tact acquisition for individuals with aphasia due to acquired brain injury. A second goal was to evaluate the transfer of shortened latencies as a function of tact training across untrained operants. In Study 1, the dependent measure was accuracy of responding and in Study 2, the dependent measures were rate and latency of responding. Participants for Study 1 were two uninjured adults (pilot) and two adults with brain injury (ABI). Both sets of participants were directly taught to tact up to 6 stimuli. Once tacts were acquired, the response forms were assessed under mand and intraverbal conditions. All pilot participants and one ABI participant showed mand transfer for all stimuli. Tact to intraverbal transfer varied across participants. One adult with brain injury served as a participant for Study 2. Fluency training was used to teach tacts for 15 stimuli. Response latencies were gathered for all operants before and after training. The participant met the designated aim (rate of responding) and showed a decrease in latencies for tacts and untrained intraverbals. Changes in mand latencies varied. Fluency gains showed partial retention. Results from Study 1 provide …

The study of choice and allocation has often focused on certain parameters of reinforcement, but rarely on historical variables. The goal of this study was to investigate the potential effects of gradual vs. abrupt teaching methods on future response allocation. A secondary goal was to see if the results of teaching-method manipulations might be correlated with the parameters that the teaching method produced, specifically unit costs, rate of reinforcement, or error rates. Results indicate that these teaching procedures can produce transient shifts in allocation, but not in a consistent direction. Neither unit cost nor rate or reinforcement alone can account for observed response allocation shifts after training. Researchers saw that subjects reliably shifted towards a manipulanda that produced higher rates of errors, therefore investigating the influence that error rate (or types of errors) may have on response allocation may aid in general teaching method preferences. Future research could focus on the combination of historical procedural variables and current variables that could determine response allocation.

The present study evaluates the effects of incompatible verbal behavior when engaging in the Wisconsin Card Sorting Test (WCST). The WCST is a complex task that requires participants to match stimulus cards based on self-generated rules. After a varying number of trials, the rule changes and the participant will have to self-generate a new rule. Verbal behavior, specifically joint control, is likely involved in rule-following. Seven participants took part in this study. Participants engaged in the WCST either silently or while performing a putatively incompatible behavior, counting backward from 100 to 0. Results suggest joint control might be involved as when participants engaged in the incompatible behavior their performance was affected in terms of lower accuracy and longer reaction times compared to the silent baseline.

Storytelling is a practice that is used to pass down important information about culture, environment, and history. From a behavior analytic perspective, the process of storytelling involves contingencies and can be viewed within the framework of the Skinner's analysis of verbal behavior. For each listener, based on their history of learning and experiences, stories enable a unique type of learning about reinforcers, punishers and cultural context. In African American oral tradition, storytelling was and still is important in preserving the identity, safety, and wellbeing of African Americans. The purpose of this project was to inductively explore story telling between youth and elders in an African American community. A training workshop was developed that included an overview of the importance and role of storytelling in the black community and ways for youth to respectfully listen and learn from elders. The participants included two children and one elder. The independent variable was the training package, the dependent measures included the levels of synchronous engagement, the listener behaviors of the youth and the participant voices, that is, the descriptions and reflections of children and elders about the process and outcomes of this project. A multiple probes design across skills with in-vivo generalization check …

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.

This study explored the effects of cultural consequences identified through a ranking task on the selection of interlocking behavioral contingencies and aggregate products constituting ethically self-controlled responses when participants had pre-existing relationships. Two experiments were conducted to explore these effects. Experiment 1 had two triads of three participants each recruited from a university-based autism center. Experiment 2 had three triads of three participants each; participants in Triads 3 and 4 were recruited from a university-based rock-climbing club while participants in Triad 5 were recruited from the same university-based autism center as in Experiment 1. All participants were exposed to a task that involved choosing odd or even rows from a matrix displayed throughout the experimental session. Individual contingencies were programmed in all conditions while metacontingencies were programmed in some conditions. Participants selected the topography of the cultural consequence through a pre-experimental ranking task prior to the onset of the experimental session. A change was made to the experimenter's verbal behavior in all operant and metacontingency conditions for Experiment 2. The results of both experiments indicate that identification of the cultural consequence through a ranking task with participants having pre-existing relationships did have an effect on the continued selection of the …

Percentile reinforcement schedules have been used to systematically alter inter-response times, behavioral variability, breath carbon monoxide levels, duration of social behaviors, and various other properties of behavior. However, none of the previous studies have examined the effectiveness of percentile schedules in relation to the magnitude of muscular contractions. This control over magnitude of muscular responding has important implications relating to the strengthening of muscles and correct movements for patients receiving physical rehabilitation. There would be great utility in percentile schedules that can be implemented in rehabilitation situations by physical therapists and patients themselves to improve treatment outcomes – all of which could be possible without any behavioral training if the procedure is implemented via body sensors and smartphone applications. Using healthy adults and the aforementioned technology, this thesis focused on the design and testing of three percentile reinforcement schedule procedures to increase the strength of the vastus medialis muscle. Results indicate that the magnitude of muscular responses can be shaped using body sensors and contingent feedback, and the percentile schedule procedures have promising applications in the domain of physical therapy.

Interobserver agreement (IOA) was calculated across three participant dyads for a generalized treatment integrity tool. No dyads achieved 80% agreement during baseline. Task clarification was piloted as an intervention for two of the three dyads. Form agreement produced stabilization in both dyads and improvement in one dyad. Time agreement did not improve but demonstrated marked trends in one dyad.

Most horse owners administer oral deworming medication to their horses on a set schedule, often six times per year. The deworming process involves using a plastic syringe to inject a thick paste into the horse's mouth. Most horse owners do not specifically train their horses to accept this procedure. Consequently, many horses resist the procedure and some horses engage in behaviors, such as head shaking, pulling away, or even rearing, that may be dangerous to humans or to themselves. This study used a negative reinforcement shaping procedure to train six horses to accept dewormer medication. The procedure consisted of a food sampling phase followed by three shaping phases that simulated the deworming task, first using only the experimenter's hand, then a small syringe, and finally a large syringe. Once the horse was acclimated to the syringe, the horse's preferred liquid food was delivered through the syringe at the end of each trial. By the end of the study, all participants successfully completed the procedure and were able to stand still with no or minimal head movements while being dewormed.

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.

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 …

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 …

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.

Diversity can serve as both a unifying force as well as grounds for intolerance of differences. Behavior analysts working in applied settings often encounter diversity and it is in these settings that meaningful relationships and harmonious collaboration are vital. Skilled dialogue has been recommended as an approach to capitalizing on diverse perspectives so that new solutions and meaningful relationships are developed. The purpose of the present study was to evaluate the effects of a training workshop to teach skilled dialogue to behavior analysts. The participant was trained to provide welcoming, allowing, sense-making, appreciating, joining, and harmonizing statements using instructions, rationales, models, role-plays, and feedback. The effects of the training workshop were evaluated using a multiple baseline design across training components. Audio responses to role-play scenarios were recorded, transcribed, and scored in order to assess the effects of the training workshop on communication skills. The results of the study indicated that this training workshop is an effective method to teach behavior analysts to engage in the components of skilled dialogue, hopefully contributing to harmonious collaborative communication in their work settings.

Behavior analysts often work with families from diverse cultural backgrounds. Ideally, behavior analysts and families interact in ways that are responsive to the family's culture and valued outcomes. The data indicate that most behavior analysts, however, come from one dominant cultural group. This is a proposal for training program and evaluation method to support culturally responsive professional-family interactions. This proposed study is designed to be conducted via Zoom-- a cloud-based video conferencing service. A pre-post treatment design is proposed to assess the effects of the training. Hypothetical data were generated to consider the range of effects such a program might have on trainee responses to written/live scenarios. Responses in the observation protocol included written descriptions, empathetic statements, perspective taking statements, and non-verbal behaviors. Overall, the program was designed using evidence-based procedures and is likely to support behavior analysts in training and in practice to improve their interactions with families and become more culturally responsive to groups of people that are from the non-dominant culture.

University peer-mentoring programs have shown to increase the retention rates of students, including students with autism spectrum disorder (ASD), and improved satisfaction with the college experience. The perceived quality of a mentee-mentor relationship may predict satisfaction with a peer-mentoring program; therefore, teaching peer mentors to engage in behaviors that could contribute to a high-quality mentee-mentor relationship may be beneficial. The current study identified target outcomes, operationally defined target behaviors, and developed a computer-based instruction (CBI) training module. The CBI training module was divided into four submodules that incorporated teaching through examples and nonexamples and discrimination training. The efficacy of each CBI submodule was evaluated using a pretest/posttest design with two mentors in a university peer-mentoring program. Results suggested that the CBI training module produced an increase in the frequency of correct responses in seven out of eight submodule posttests across both participants. The CBI training program also produced an increase in the frequency of target behaviors emitted by both participants across all submodules. These findings suggest that this CBI training module can be used to teach peer-mentors the behaviors that may improve their relationship with their mentee.

Previous research has incorporated instructive feedback (IF) within mastered listener-by-name trials with two children diagnosed with autism spectrum disorder (ASD). Participants in a previous study acquired the secondary targets and also demonstrated emergent responding (i.e., listener-by-feature, tact-by-feature, intraverbal, and reverse intraverbal). The current study replicated a previous study on IF with two children with ASD. Therapists conducted a series of three sessions of mastered listener-by-name trials (e.g., "Show me otter," and the participant selecting the picture of the otter) and provided IF statements for features of the target stimuli (e.g., "It lives in rivers."). We measured participants' echoic responding and required attending to the target stimulus during IF trials, and we evaluated acquisition of secondary targets and emergent responses using a concurrent multiple probe design across sets. We observed increased correct responding for secondary targets and emergent responses for the first set of stimuli with both participants. However, one participant did not engage in emergent responses for the two remaining sets. Results suggest that related verbal operant response relations of secondary targets may result after IF, but the extent of emergence may be idiosyncratic.

An important question in teaching language is, what accounts for the emergence of either receptive or expressive labels when teaching only one of them? The teaching procedures in the present study were intended to reproduce the natural development of bidirectional naming in which caregivers comment on the items a child is interacting with and children echo those vocalizations they hear. Thus, the only vocalizations presented by the researcher during teaching occurred after the learner pointed to a specific stimulus, and were specific to the stimulus being targeted. These vocalizations are referred to in this study as stimulus-specific consequences. The purpose of this research was to investigate if the stimulus-specific consequences could become discriminative stimuli for receptive labels, and lead to the emergence of expressive labels. Three studies were conducted, each with four adults. Results demonstrated that using a stimulus-specific consequence during teaching led to receptive labels for all participants, but led to the emergence of expressive labels for only four participants. In other words, bidirectional naming did not occur for the majority of participants. Factors that may improve interrelations between receptive and expressive labels were analyzed, but further evaluations are needed to account for the inconsistent demonstrations of naming.

The present study investigated how engaging in a behavior that is potentially incompatible with covert verbal behavior, singing aloud, affected the percent of correct responses and reaction time during equivalence tests as compared to engaging in a behavior considered compatible with covert verbal behavior, alternating foot tapping, during testing. Results varied between participants with some participants showing higher accuracies in the incompatible condition and some in the compatible condition. Performance in terms of accuracy and reaction time were correlated, with higher accuracies in the compatible condition being correlated with faster reaction times in the compatible condition. Limitations discussed include a low number of participants due to COVID-19, the covert nature of the behavior of interest, the length of time required to complete the experiment, and the challenges to monitoring the incompatible behavior due to social distancing requirements. Potential future research is discussed in light of these limitations.

Wii Fit U games utilize a Wii Balance Board™ (WBB) in a manner that can provide precise feedback contingencies similarly to some forms of balance rehabilitation, thereby potentially increasing the dose of quality therapy with or without the presence of a therapist during post-brain injury rehabilitation. Additionally, an engaging video-game could improve treatment adherence, a critical aspect of making positive functional gains, by potentially increasing the rate and quality of reinforcement embedded in therapy. The present study had three aims: (1) develop a rigorous behavioral therapy for improving balance in individuals living with chronic brain injury using a Wii Fit U game and the WBB; (2) evaluate the program's effects on balance measures using a within-subject experimental design; and (3) assess social validity of behavioral gains by evaluating the program's effects on participant's "subjective balance confidence" (i.e., their Activities-Specific Balance Confidence (ABC) scores). A reversal design is proposed for use with primary study participants, wherein the experimental gameplay condition and no intervention condition are alternated for 6 to 10 weeks. A similar design was used in a truncated fashion with pilot participants, and a multiple baseline design was used with follow-up pilot participants. It was expected that participants would exhibit …
