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.

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.

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 …

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.

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 …

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.

Children acquire many skills through play. These range from fine and gross motor skills, social skills, problem-solving, to even creativity. Creativity or creative engagement is frequently a component in early preschool curricula. A pivotal repertoire to engage in behaviors deemed creative, such as art, storytelling, problem-solving, and the like, is the ability to vary one's responses regardless of the specific repertoire. Researchers have developed methods to produce response variability. However, notwithstanding the significant contributions from the literature for prompting response variability, it remains unclear how much variation in responding is socially appropriate. To fill this research gap, the purpose of this study is to characterize and understand the different ways preschool children commonly interact with the activities and materials present in a preschool classroom. In our study, we assessed children's repeat item interactions, novel item interactions, and time allocation across seven concurrently available activity centers. A multifarious pattern for item interactions emerged across children. Some children had restricted levels of novel item and center interactions, while other children had more varied novel item and center interactions. However, the variance in interactions was predominantly controlled by the center type. This study bolsters our understanding of variability and creativity within a school …

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.

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.

Prejudice establishes coercive contingencies that restrict human rights and diminish quality of life. Social media has made the oppression experienced by individuals more apparent. Perspective taking and empathy can change prejudicial behavior by fostering relationships and encouraging self-identification with those who are different from ourselves. The purpose of the present study was to evaluate the effects of a guided collective shaping program on the occurrence of perspective taking and empathetic responses when viewing social justice media. The effects of the workshop were evaluated using a multiple baseline design across workshop topics. Written responses to video clips were analyzed before, during, and after training. The results of the study were inconclusive. The results of the training, based on the responses measured, indicate an increase in one measure of perspective taking and no changes in the other measures. At the same time, anecdotal observations indicated a change in the way participants talked about the issues over the course of the training. The results are discussed within the context of response form measurement, the COVID-19 pandemic, and potential research directions.

Researchers investigated how the contingent delivery of a cultural consequence on target culturants in an asymmetric iterated prisoner's dilemma game (IPDG) affected players' choices. The asymmetric IPDG creates an analogue to income disparities created by wage gaps and other cultural practices that create wealth inequalities between different members of the population and allows researchers to explore how these inequalities affect cooperation between players. Six undergraduate students divided into three dyads participated in an ABABCDCD reversal design. An asymmetric IPDG was arranged in Condition A and C such that one player received a greater number of points regardless of the second participants' selections - analogue to contingencies that produce income inequalities from wage gaps. In Condition B and D, a metacontingency was arranged such that delivery of a cultural consequence (CC; bonus points equally distributed among the dyad) was contingent on the oscillating production of target aggregate products (AP) across two consecutive cycles. When participants' coordinated responding and contacted the target AP→ CC relation, the wage gap was reduced. However, individual contingencies are in direct competition for the "wealthier" player, reducing the probability of cooperative responding. Results showed the CC selected certain oscillations between target APs resulting in a decrease of …

Current food production methods in the United States contribute to environmental degradation as well as food insecurity. Food production by means of community gardens has the potential to reduce the deleterious effects of current production methods. However, many community gardens face challenges that hinder their longevity, thereby reducing the likelihood of the support they might provide for environmentally sustainable food production and decreased food insecurity for community members. A behavioral systems science approach was combined with ethnographic research methods, matrix analysis, and a literature review regarding best practices for community gardens to study the cultural practices of three established community gardens in the southwest region of the US. The results of the analyses conducted are presented in terms of recommendations to support each target community garden's sustainability. Recommendations regarding future research include environmental manipulations to identify functional relations and potential outcome measures for improving the longevity of community gardens are provided.

The exponential growth of the human population has contributed to the overuse and degradation of common pool resources. Using science as a tool for informed policy-making can improve the management of our common pool resources. Understanding the conditions that influence groups of individuals to make ethical self-controlled choices may help solve problems related to the overuse and degradation of common pool resources. Ethical self-control involves the conflict of choice between one that will benefit the individual versus one that will benefit the group. The cumulative effect of many individuals behaving in an ethically self-controlled manner with common resource use may offset some of the harm posed by overuse of common pool resources. Metacontingency arrangements involving ethical self-control may provide some insight as to if and how groups may cooperate to manage a common pool resource. This manuscript proposes an experimental preparation and methodology to evaluate the effects of competing magnitudes of cultural consequences on culturants and their cumulative effect on common pool resources; and provides an analysis and discussion of five trends that might result from such a line of research.

The goal of this study was to use a nonlinear approach to create a program to teach positive and negative reinforcement and punishment. A specific interest was to determine whether the program and its testing allowed for specific recommendations for future iterations of the program. The tests and program developed for this study were completed by 18 participants. Pre-test and post-test data showed that participants learned the most about positive contingencies, nonexample items, and ambiguous contingencies. Participants learned the least about negative contingencies. The data also revealed where additions to the instructional program were needed to produce better outcomes in future versions of the program.

Sometimes, changes in consequences are accompanied by a clear stimulus change explicitly arranged by the experimenter. Other times when new consequences are in effect, there is little or no accompanying stimulus change explicitly arranged by the experimenter. These differences can be seen in the laboratory as multiple (signaled) schedules and mixed (unsignaled) schedules. The current study used college students and a single-subject design to examine the effects of introducing signaled and unsignaled schedules, and the transitions between them. In one phase, a card was flipped from purple to white every time the schedule was switched from VR-3 to FT-10. In another phase, the schedule still changed periodically, but the card always remained on the purple side. Results showed that the participants' responding was controlled by the schedule of reinforcement, by the color of the card, or both. These results suggest that changes in patterns of reinforcement lead to changes in stimulus control. In addition, the stimulus control for a behavior can come from several different sources. During teaching, it may facilitate the development of stimulus control to change the environment when a new behavior is required.

The term "resurgence" generally refers to the reappearance of certain behaviors during extinction. Different definitions describe these behaviors as previously reinforced, previously extinguished, or simply previously learned. At first glance, these definitions seem the same. And, researchers have not given much thought to the differences between them. However, these definitions could refer to different initial teaching procedures, and these differences may produce different results during extinction. The present study used the Portable Operant Research and Teaching Lab (PORTL) to examine how differences in the initial teaching procedure affected the behavior of college students during extinction. In the first condition, participants learned four behaviors. Each behavior was extinguished before the next behavior was taught. When all four behaviors were put on extinction, they resurged in the reverse order from how they were taught. A second condition followed the same procedure as the first with one difference. Each behavior was not extinguished before the next behavior was taught. When these four behaviors were put on extinction, they resurged in the order they were learned. These results indicate that the initial training procedure can influence the order in which behaviors appear during extinction.

Participants demonstrate the Stroop effect when, in naming the color in which a word appears, reaction times are longer when the color and word are incongruent (e.g., "yellow" printed in blue) compared to when they are congruent (e.g., "yellow" printed in yellow). The literature commonly refers to the difference in reaction times as a measure of the interference of word stimuli upon color stimuli, and is taken as support for the theory of automaticity. This study asks whether the Stroop effect can be analyzed as interactions within and across stimulus classes. Adult participants learned three 3-member classes (color, word, and pattern) in a serialized order of training. In the testing phase, participants were presented with compound stimuli formed from combinations of members within and across classes (e.g., word and color), and reaction times were recorded in similar fashion to the Stroop task. Results show that averaged participants' reaction times are faster to compound stimuli comprised of members within the same class, compared to compound stimuli formed with members from different classes. These group-level data are consistent with the Stroop literature in that congruent compounds produce faster reaction times relative to incongruent compounds. However, individual participant data do not consistently reflect …

The present series of experiments were designed to investigate the utility of the use of a masking system to assess the development of stimulus control. The first experiment compares sample observing time with response accuracy in a match-to-sample task. The second experiment more closely examines this relation by subdividing the sample stimulus mask into four quadrants. The third experiment compares sample observing time during training with accuracy during a subsequent testing condition to determine if the observed differentiation between the quadrants was correlated with the development of stimulus control.

There is a limited amount of research that has evaluated all three types of modalities and consequences during stimulus preference assessments (SPA) or examined problem behavior during preference assessments with individuals with tangible maintained problem behavior. Therefore, the purpose of this study was to extend this line of research in two ways: (a) compare results of SPAs across three modalities and two consequence, (b) evaluate problem behavior during these SPAs with individuals with problem behavior maintained by access to tangible items. The results indicated that for all participants, there was preference stability across modalities and conditions. For all participants, problem behavior occurred during the no access condition or removal regardless of modality.

Using a multiple baseline across participants with a changing criterion, this study explored and evaluated the effects of the individualized contingency management package (goal-setting, education, etc.) with sedentary typical adults while focusing on the mentoring component and the use of the technology of the exercise tracker to increase and sustain physical exercise to a level that increased health-benefiting physical activity. During initial mentoring meeting prior to the start of baseline, each participant was given a Garmin Viovsmart 3® exercise tracker, educated on the basic components of the device, and connected to the dashboard through the Garmin Connect™ app on their smartphones. Once each participant's activity stabilized, participant began intervention with weekly mentoring meetings focused on immediate feedback (social reinforcement), goal-setting and education. Through the Connect™ app, experimenter gave social reinforcement on a VR3 schedule to each participant, and participants were encouraged to participate by commenting to other participants through a private group set up for this study. The results indicate that the individualized contingency management package was effective for three of four participants whom increased their total activity minutes from pre-intervention range 0-104 min of weekly activity to post-intervention range of 269-404 min weekly. The two participants that completed two- …

Functional analysis is considered best practice for behavior analysts who work with people who have intellectual and developmental disabilities and engage in problem behavior. Unfortunately, a majority of practitioners do not complete functional analyses. The purpose of the present study was to train 10 practitioners to implement a practical functional assessment (PFA) decision making model and to evaluate the ecological validity of the model. Pre- and Post-training overall test scores increased, on average, by 38.18%. Testing subsections increased by 60.0% for foundations and concepts, 5.0% for graphical interpretations, and 40.0% for decision making. A job needs survey showed the greatest gains in reports of antecedent environmental supports, behavior supports in the environment, and antecedents related to the behavior repertoire. A post-training survey indicated that 8 of 8 trainees would recommend the training to others. Finally, at the conclusion of follow-up progress data collection, 3 of the 5 locations were progressing through the PFA model in their regular job duties whereas the other 2 locations experienced professional staffing issues that interfered with their workloads. These results indicate that the training was effective at increasing testing responses related to foundations and concepts as well as decision making. Additionally, when professional staffing was …

Training parents of a child with autism to increase the frequency of their child's social behavior may improve the quality of parent-child interactions. The purpose of this methodological study was to develop a direct observation method for rapidly sampling social harmony between parents and their toddlers with autism during parent training interactions. The current study used a pre and post probe design, with benchmark comparisons to test the discriminability of the measurement protocol across two sets of data. The first set of data came from pre and post training videos from a parent training program for children with a diagnosis of autism or at risk for a diagnosis. The second set of data came from videos of typically developing toddlers and their parents. The results of the study show that the measurement system differentiated in the level of harmonious engagement between the benchmark sample and the sample including children diagnosed with autism. The results are discussed in the context of future directions and the utility of the measurement system for behavior analytic practices in parent training and other settings where rapport and complex interactional behaviors are an intervention priority.

Although behavior analysts have studied the effects of motivation on preference assessments, consumer behaviorist have not. The purpose of this study was to analyze the effect of the temporary removal of a choice on the order and frequency of purchases after the candy returned. Seventy percent of the time the participant purchased the removed candy first and 60% of the time the participant purchased more than in the baseline.
