Animal trainers use shaping to teach many behaviors. However, during shaping, the organism may engage in behaviors other than the target behavior or approximations to the target behavior. If the animal is engaged in other behaviors, the rate of reinforcement may decrease and the trainer may resort to what is sometimes referred to as a “desperation click.” That is, the trainer delivers one reinforcer for a behavior that is not a successive approximation to the target response. Anecdotal reports from trainers suggest that sometimes the animal continues to repeat this other behavior that received only one reinforcer, even in the absence of further reinforcement for that behavior. This study compared whether, during a one minute extinction period, participants spent more time engaged in a behavior that had been reinforced only once after a brief period of no reinforcement or in a behavior that had been reinforced multiple times. Participants, who were university students, played a tabletop game that involved touching and manipulating small objects. Five conditions were repeated twice for each participant: reinforcement for interacting with a training object alone, reinforcement for interacting with a training object with other objects present, reinforcement for interacting with a target object, one reinforcer …

The study applied behavior analytic principles to foreign language instruction in a college classroom. Two study methods, vocabulary banks and scripts, were compared by assessing the effects on Italian language acquisition, retention, and generalization. Results indicate that students without prior exposure to Italian engaged in more exchanges and emitted more words in script tests compared to vocabulary bank tests. Participants with at least two classes in Italian prior to the study engaged in more exchanges and emitted more words during vocabulary bank tests. Data suggest that different teaching strategies may work for different learners. More research is needed to determine efficient teaching methods and how to ascertain which approaches work best for learners with different histories.

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 …

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.

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 …

Human operant studies frequently use points exchangeable for money as reinforcers. Some studies employ more immediately consumable reinforcers to emulate properties of food reinforcers. This study examined demand for points/money and for sound-clips to compare their economic characteristics. Across four participants, demand was often higher and less elastic for points/money than for sounds. During subsequent exposures at each response requirement, demand for sounds often decreased to a greater degree than demand for points/money. Thus, sound-clips seem less durable than points/money across prices and across repeated exposure to the same price. Response rates for points/money were often higher than for sounds, suggesting that reinforcers that generate higher response rates may be less elastic than reinforcers that generate lower response rates.

This experiment examined the effects of extinction on rate of responding and several topographical and temporal measures in adult humans. Three college students were trained to type the sequence 1•5•3 on a numeric keypad on a computer. The subjects were exposed to different fixed-ratio schedules of reinforcement (FR1, FR 5, and FR10 respectively) and extinction. Subjects displayed typical schedule performances during the maintenance phase of the experiment. During extinction the performances were disrupted, they showed a "break and run" pattern and a general decrease in responding. Also, new topographical and temporal patterns emerged. These data are consistent with those reported for non-human species and special human populations.

Literacy is a fundamental to all areas of learning. Early reading experiences prior to elementary school and kindergarten years are critical factors for later reading success. This study evaluated the effect Direct Instruction® reading procedures vs. Scholastic Early Childhood Program® reading procedures on the production of letter names, letter sounds, CV and CVC blends by preschool-aged students in a Head Start program. Results showed the intervention group improved in all areas, while the control group improved only in letter naming and letter sounds. This study discusses reading as a behavioral cusp as well as limitations, and recommendations for future research.

The present experiment compared two methods of training a simple arm position using auditory feedback: capture and search. The participants were four right-handed female college students. During capture, auditory feedback was delivered by the experimenter after the participant moved along a single axis into the target position. During search, auditory feedback was produced by the computer after the participant left clicked a mouse inside the target location. The results of a multi-element design showed that participants performed more accurately during capture training than search training. Pre-training and post-training probes, during which no auditory feedback was provided, showed similar fluctuations in accuracy across probe types. A retention check, performed seven days after the final training session, showed higher accuracy scores for search than capture, across all four participants. These findings suggest that TAGteach should incorporate an approach similar to search training to improve training outcomes.

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.

College students participating in dyads played a game designed as an analog of early hunters whose survival, as a dyad and ultimately individually, depend on rabbits they hunt. Dyadic fitness was defined as both participants being able to hunt and it was measured by the proportion of trials in a condition that both participants hunted. The effects of scarcity (alternating rich and poor conditions) on dyadic fitness were examined in two experiments. First experiment results did not show a difference in dyadic fitness as a function of the independent variable. The second experiment increased the number of hunting seasons and also the discrepancy between scarcity in rich and poor seasons. Second experiment results show that dyads start fit in rich seasons and become increasingly fit in poor seasons. External variables could not be ruled out; therefore, additional experiments still need to be carried out to clarify results.

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.

Observing emotional responses is recognized as a valuable clinical skill in a variety of professions, including applied behavior analysis. Emotional responses can flag possible contingencies thereby guiding a behavior analyst to better select valid measures, goals, and procedures. Additionally, emotional responses can be goals in and of themselves. The purpose of the present study was to evaluate the effects of a workshop on the observation and description of emotional responses by behavior analysts-in-training. The procedures included instructions, modeling, practice, discussion and feedback. The workshop included a blend of trainer presentation and interteaching strategies. The effects of the workshop were evaluated using a single-subject A-B design with multiple probe measures across four students. During probe assessments participants watched short video clips of family interactions and wrote a descriptive narrative in response to several questions. This created a permanent record for quantitative evaluation and analysis. The study resulted in an increase in the number of descriptions of emotional responses among all participants. The participants also increased responses tying the emotional response to external environmental events more often in the post-workshop assessment than the pre-workshop assessment. Results are discussed within the context of training applied behavior analysts, the analysis of verbal behavior, and …

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.

The banquet staff at a north Texas hotel were responsible for setting up 11 different functions (e.g., buffet dinners) for conferences and meetings. The functions were often set up late and items were often omitted. An analysis suggested that performance problems were the result of weak antecedents, inefficient work procedures, inadequate training and a lack of motivating consequences. An intervention consisting of task checklists, feedback, goal setting, monetary bonuses, training and job aids was designed to enhance the accuracy and timeliness of function setups. Performance increased from an average of 68.8% on the quality measure (accuracy plus timeliness) in baseline, to 99.7% during the intervention phase. Performance decreased to 82.3% during a follow-up phase in which parts of the intervention were discontinued by hotel management. Performance increased to 99.3% with the reintroduction of the intervention phase.

This study was a program evaluation for an autism treatment center for the period of April 2008 through August 2011. the study extended previous evaluations of the autism treatment center. the purpose of this evaluation was to determine the degree to which the center’s measures corresponded with its stated mission goals. a number of data sources were reviewed including client records of demographic and outcome information. Findings suggest the center maintained records that allow for the evaluation of most of its mission’s goals. There were, however, difficulties with data collection, storage, and retrieval. the present program evaluation found that missing information and lack of follow-up information hindered efforts toward mission evaluation.

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.

An analysis of interrater agreement across multiple respondents on two anecdotal assessments, the Motivation Assessment Scale (MAS) and the Functional Analysis Screening Tool (FAST), was completed for an individual who displayed aggressive behavior. The results of the assessments indicated high agreement across assessments and respondents that the problem behavior was maintained by social positive reinforcement in the form of contingent delivery of tangible items. By contrast, a subsequent experimental analysis indicated that the behavior was maintained by escape from demands. A treatment was implemented based on the functional analysis outcomes to determine if the functional analysis had correctly identified the maintaining variable of the aberrant behavior. Results of the treatment analysis showed significant reductions in the occurrence of aberrant behavior suggesting that the MAS and FAST may not have accurately identified the maintaining variable of the aberrant behavior.

Earlier identification of autism allows for interventions to begin during toddlerhood. Literature suggests that parents are an important part of very early intervention and specific goals have indicated that they are important to progress. The use of telemedicine may increase access to interventions. The purpose of the study was to evaluate a parent-toddler training program that targeted social-communication skills and incorporated a telemedicine component. Measures included parent teaching targets, child attending, vocal requesting, and coordinated joint attention and the parent's response to coordinated joint attention. Results indicate that parent teaching increased, child attending and vocalizations increased, child coordinated joint attention increased, and the parent's response to coordinated joint attention was primarily social in nature. Analysis of the home observations indicates that direct in home observations or teleconference observations neither under or overestimated behaviors. The results are discussed in the context of teaching and feedback delivery and selection of teaching targets.

This study examined the effects of fluency-based instruction on the identification of six component-composite relations for early reading skills. Five participants (ages 5-8) who struggled with reading participated. A multiple probe design was used to assess the effects of frequency building on prerequisite skills on the emergence of composite reading skills. The results show that the prerequisite skills taught did not have an effect on the composite skill probes but did have an effect on the assessment scores. The data expand the research pertaining to Precision Teaching, fluency-based instruction, and component-composite relations. These data suggest that additional skills may be needed to be taught in order to effects on the composite skills. In addition, these authors identify the need for the identification of the component skills necessary to teach rapid autonomic naming.

A comprehensive measurement system was developed to monitor play in children with autism and typically developing children. The study was conducted in a preschool operated in conjunction with a center-based program for children with autism. The development of the measurement system was based on observations of four children with autism and three typically developing children during social and play activites. Data were collected on material use and several dimensions of play: Simple Manipulation, Functional Manipulation, Symbolic Toy Play, Symbolic Role Play and Play Themes. The results indicated that the measurement system consistently measured a wide range of play behaviors across children and materials. Significance of the information gathered from the measurement system in assessing play and designing interventions is discussed.

In order for the benefits of a behavior management skills training program to reach clients, caregivers must use the behavior management skills in the natural environment. The current study took place at a large residential facility for adults with disabilities, in which caregivers had received prior training in which they demonstrated behavior management skills and maintained those skills in contrived role plays. The current study represents a preliminary analysis of generalization of these skills in the natural environment; thus, a measurement system for when caregivers should demonstrate the tools was developed. The specific purpose of this study was to develop and evaluate a program to establish stimulus control over observers' measurement of appropriate behaviors. Researchers systematically developed and validated a measurement system of "good behaviors" that could be used across clients. The process of development and refinement of the measurement system is described. When the system was finalized, three observers' accuracy in using the system was assessed by comparing measured values to that of the code writer. Following feedback on individual instances of behavior, all observers scored the three target behaviors accurately. Ecological validity was assessed by surveying professionals at the facility and ecological validity results suggested a valid measurement …

Online shopping has rapidly expanded in the last decade. Online shopping necessarily imposes delays on all transactions. Behavior analysis has long studied the effects of delay on choice. Additionally, a number of researchers are beginning to study consumer behavior using a behavior-analytic approach. The current study attempted to extend research focusing on consumer behavior in online contexts. The experimenters attempted to evaluate whether goods acquire functional properties and whether these properties influence consumer choice. The researchers were specifically interested in studying acquisition costs and durability and in simulating a natural online shopping environment. Results from the current study extend the findings showing that delay and price influence choice. The data from the current study provide mixed evidence for control by item durability.

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.
