Differential Reinforcement Of Alternative Behavior Research Articles

DRA dengan Token Ekonomi untuk Menurunkan Perilaku Makan yang Menyimpang: Sebuah Studi Kasus pada Anak

Children of homeless people often experience various issues, one of which is eating behavior problems. Eating food from trash cans is a common eating behavior problem encountered. Therefore, an intervention is needed to reduce this issue. This case study aims to test the effectiveness of differential reinforcement of alternative behavior (DRA) with token economy in reducing eating behavior problems. Assessment is conducted through interviews, observations, and psychological tests, while the intervention is carried out over nine sessions. The results of the intervention show a decrease in the behavior of taking food from trash cans. In addition to replacing old behavior with more adaptive behavior, the role of attention from adults around them is one of the main contributors to the effectiveness of the intervention.

Increasing leisure‐item engagement in individuals with autism

AbstractThe goal of the current study was to increase functional engagement with multiple leisure items for five individuals with ASD, who had limited leisure item engagement (i.e., they engaged with only one leisure item, and after that item was restricted, they exhibited no functional engagement with alternative activities). Response restriction (RR) preference assessments were conducted to assess pre‐ and post‐training performance to determine if training was necessary and if performance maintained following training. A component analysis that involved progressively adding intervention components (prompting alone; prompting plus differential reinforcement of alternative behavior), and targeting simple engagement prior to functional engagement, was conducted. For all participants, the progressive treatment approach was effective in increasing functional engagement to criterion levels for all trained items. However, the effective training component(s) varied across participants and items. During the final post‐training RR assessment, functional engagement maintained with all trained items for all participants.

Resurgence of goal-directed actions and habits.

This study investigated how goal-directed and habitual behaviors recover after extinction within the context of the resurgence effect, a form of relapse induced by the removal or worsening of alternative reinforcement. Rats were trained to press a target lever with one reinforcer (O1) for either minimal (4) or extended (16) sessions. An extinction test after the completion of O1 devaluation confirmed that minimal and extended training formed goal-directed and habitual behaviors, respectively. Then, pressing an alternative lever was reinforced with a second reinforcer (O2) while the target response was placed on extinction. When O2 was discontinued, the minimally trained target response resurged with goal-directed status as in the extinction test. However, the extinguished habitual behavior in the extensively trained rats did not recover as a habit but instead with goal-directed status, possibly due to the context specificity of habits or the introduction of a new response-reinforcer contingency. The critical finding that reinforcer devaluation consistently led to less resurgence regardless of the amount of acquisition training provides a clinical implication that coupling differential-reinforcement-of-alternative-behavior (DRA) treatments with the devaluation of the associated reinforcer of problematic behavior could effectively diminish its recurrence.

Translational evaluation of on/off alternative reinforcement cycling.

Cycling between the availability and unavailability of reinforcement for alternative responding has successfully reduced resurgence in basic laboratory evaluations, but this approach represents a marked departure from current standards of care when treating problem behavior, warranting careful translation before its use clinically. Therefore, with extinction arranged for target responding across groups in Phase 2, we evaluated the effects of cycling between the availability and unavailability of differential reinforcement of alternative behavior (DRA) using a computer-based task with adult humans recruited through Amazon MTurk. Two control groups experienced constant DRA in Phase 2, with one group experiencing a dense DRA schedule and another group experiencing a lean DRA schedule. The cycling DRA group tended to show greater reductions in target responding and improved discrimination in Phase 2 and less target responding across Phases 2 and 3 than the lean DRA and dense DRA groups. These preliminary findings suggest that on/off DRA cycling procedures may produce more desirable treatment outcomes than constant DRA without producing negative side effects; however, further research is needed to confirm these possibilities.

Examining resurgence in rats following expanded-operant treatments.

Resurgence of previously reinforced behavior represents a challenge to otherwise successful interventions based on differential reinforcement of alternative behavior (DRA). Expanded-operant treatments seek to increase the number of functional alternative behaviors through DRA, thereby potentially mitigating resurgence. However, the few studies that have directly examined these methods as a tool for resurgence mitigation have provided limited and unclear results. Thus, the present experiments were designed to investigate the effect of expanded-operant DRA methods on resurgence of previously reinforced behavior using rat subjects. In two experiments, following a baseline phase in which a target response was trained, groups of rats experienced concurrent (i.e., five simultaneous alternative responses), serial (i.e., five sequentially available alternative responses), or single DRA interventions arranging similar rates of alternative reinforcement in order to examine potential differences in resurgence. Both experiments showed that neither serial nor concurrent DRA expanded-operant treatments reduced resurgence compared with single DRA regardless of whether stimuli associated with previously reinforced alternative responses were removed (Experiment 1) or remained present (Experiment 2) for the serial-DRA group. Further, a primacy effect in resurgence was obtained for the serial-DRA group in both experiments. Overall, these results suggest that expanded-operant treatments may not help to reduce resurgence.

Concurrent schedules of differential reinforcement of alternative behavior in the treatment of problem behavior without extinction.

Differential reinforcement of alternative behavior (DRA) without extinction is an effective intervention for reducing problem behavior maintained by socially mediated reinforcement, particularly when implementing dense schedules of reinforcement for appropriate behavior. Thinning schedules of reinforcement for an alternative response may result in resurgence of problem behavior. Resurgence may be of particular concern in the treatment of problem behavior without extinction because problem behavior that resurges is also likely to encounter reinforcement and thus can be expected to maintain. In the present investigation, we compared the effectiveness of single and concurrent DRA schedules in decreasing the probability of resurgence when problem behavior continues to produce reinforcement throughout all phases of the evaluation. Concurrent DRA schedules reduced or eliminated the likelihood of resurgence compared with a single DRA schedule during a treatment challenge.

Varying reinforcer dimensions during differential reinforcement without extinction: A translational model.

Procedural arrangements of differential reinforcement of alternative behavior without extinction often involve presenting the same reinforcers for problem behavior and appropriate behavior, which is typically ineffective at reducing problem behavior and increasing an alternative response. However, manipulating reinforcement dimensions such that the contingencies favor the alternative response may improve treatment outcomes when using differential reinforcement of alternative behavior without extinction by increasing appropriate behavior and reducing problem behavior. We conducted this translational study with 32 college students completing a button-pressing task on a computer program in which they could engage in analogs to problem behavior and appropriate behavior. The effects of manipulating magnitude, immediacy, quality, and a combination of all three dimensions for the alternative response were evaluated. Overall, all dimension manipulations reduced the analog to problem behavior, with the largest reductions observed during the quality probe and the probe with all dimensions combined. These results support the notion that differential reinforcement of alternative behavior without extinction can be an effective form of treatment.

Response-strengthening effects of same- and different-context DRA training: The effects of two disruptors.

Differential reinforcement of alternative behavior (DRA) involves placing problem behavior under extinction and simultaneously reinforcing a desirable behavior. Recent research revealed that, as predicted by Behavioral Momentum Theory, DRA may also increase the persistence of the problem behavior. This research has also shown that a different approach to DRA, in which an alternative behavior is trained in a separate context from the target behavior, produces less persistence than the standard procedure. The research on this phenomenon, so far, assessed persistence using extinction as the disruptor. DRA, however, is often implemented under conditions in which extinction of the problem behavior is not feasible. This study evaluated persistence of problem behavior following same- and separate- context DRA training using an alternative disruptor, an additional source of reinforcement. Following a successful reproduction of a previous study of extinction as a disruptor but with domestic hens, this study produced similar findings using an additional source of reinforcement as the disruptor. These findings add to the evidence that alternative DRA arrangements may avoid the response-strengthening effects found with traditional DRA procedures. The findings also demonstrate that disruptors other than extinction can be used to investigate response persistence following DRA and other procedures.

Nominally acceptable integrity failures negatively affect interventions involving intermittent reinforcement.

The finding that differential reinforcement of alternative behavior (DRA) is efficacious at 80% integrity when continuous reinforcement is programmed for alternative responding may have contributed to a perception that integrity at 80% or above is acceptable. However, research also suggests that other interventions (e.g., noncontingent reinforcement) may not remain effective at 80% integrity. The conditions under which 80% integrity is acceptable for common behavioral interventions remains unclear. Therefore, we conducted two human-operant studies to evaluate effects of 80% integrity for interventions with contingent or noncontingent intermittent reinforcement schedules. During Experiment 1, we compared noncontingent reinforcement (NCR) and DRA when implemented with 80% integrity. During Experiment 2, we compared 2 variations of DRA, which included either a ratio or interval schedule to reinforce alternative behavior. Results replicated previous research showing that DRA with a FR-1 schedule programmed for alternative responding resulted in consistent target response suppression, even when integrity was reduced to 80%. In contrast, neither NCR nor interval-based DRA were consistently effective when implemented at 80% integrity. These results demonstrate that 80% integrity is not a uniformly acceptable minimal level of integrity.

Accumulated‐ and distributed‐reinforcer arrangements in the treatment of challenging mealtime behavior

AbstractTreatment for inappropriate mealtime behavior often includes extinction and differential reinforcement of alternative behavior (DRA) in a distributed arrangement in which delivery of brief reinforcer access immediately follows each appropriate mealtime response. Alternatively, DRA may be arranged using accumulated reinforcement wherein delivery of longer, continuous access to reinforcers follows the consumption of multiple consecutive bites. Research has suggested that individuals prefer and perform better under accumulated arrangements in academic settings; however, no research to date has evaluated the efficacy of accumulated arrangements with children with feeding disorders. We compared preference for and efficacy of distributed and accumulated (with and without tokens) reinforcement with nonremoval of the spoon. All three treatments effectively reduced inappropriate mealtime behavior and increased acceptance for two participants and decreased packing and increased mouth clean for one participant. Two participants preferred distributed reinforcement and one preferred accumulated reinforcement without tokens. Findings differ from some previous research, which demonstrated that participants favored accumulated arrangements in academic contexts.

Brief assessment and treatment of pica using differential reinforcement, response interruption and redirection, and competing stimuli

AbstractPica is a life threating form of challenging behavior displayed by individuals with intellectual and developmental disabilities. In most cases, pica is maintained by automatic reinforcement. Common interventions for pica use some combination of response blocking, response interruption and redirection (RIRD), differential reinforcement of alternative behavior (DRA), and noncontingent reinforcement with competing stimuli. However, there is need for additional research regarding DRA procedures that emphasize skills acquisition by teaching alternative behaviors that modify the established behavioral chain of pica responses that occur in the presence of non‐edible stimuli. There is also a need to examine the generality of recent advances in competing stimulus assessment (CSA) methodologies—namely, the augmented‐CSA (A‐CSA)—to pica. Thus, the purpose of the present investigation was to systematically replicate and extend previous research for the assessment and treatment of pica in an individual with IDD. First, we conducted a functional analysis to identify environmental variables associated with pica. Next, taught Patrick a differential response (i.e., discard pica items in trash receptacle) to earn reinforcers in conjunction with a RIRD procedure. Finally, we conducted an A‐CSA for pica. Overall, low rates of pica were maintained over time with a combination of these procedures, and treatment was generalized across settings and people.

Examining combinations of stimulus and contingency changes with children diagnosed with autism spectrum disorder and pigeons

Resurgence and renewal are relapse phenomena in which behavior undergoing extinction returns as a result of worsening of reinforcement conditions or changes in environmental context, respectively. The present experiments examined laboratory models of resurgence and renewal in isolation and in combination to assess the potential influences of these effects during treatments with differential reinforcement of alternative behavior (DRA). Experiment 1 demonstrated a greater return in arbitrary target responding in children diagnosed with autism when both changing context and removing alternative reinforcement compared with only a change in context. Experiment 2 evaluated a similar comparison by exposing pigeons to changes in context and changes in the contingency for alternative responding in isolation or combination. Consistent with Experiment 1, target responding increased most when combining contingency and context changes. Experiment 3 demonstrated greater increases in target responding with pigeons when returning to the training context and omitting higher compared with lower percentages of alternative reinforcers. This study replicated and extended previous findings that revealed resurgence of target behavior is greater when combining context changes and greater reductions in alternative reinforcement. These findings imply that context changes can exacerbate relapse with DRA treatments resulting from decreases in alternative reinforcement either through breakdowns in treatment integrity or planned maintenance strategies.

The mitigating effects of enhanced reinforcer magnitude and quality on treatment degradation.

Differential reinforcement of alternative behavior is a common intervention for problem behavior in persons with neurodevelopmental disorders, but it is susceptible to integrity errors that can degrade treatment effects. Manipulating reinforcement parameters to favor alternative behavior might make it more persistent in the face of integrity errors. We devised an analog of differential reinforcement of alternative behavior to examine if enhanced reinforcer magnitude or quality for the alternative response could protect against treatment degradation. Across 2 experiments, reinforcer magnitude or quality was manipulated to favor the alternative response in 1 condition but kept constant across both alternative and target responses in a second condition. Comparisons of the 2 conditions indicated that higher-magnitude or higher-quality reinforcement for alternative behavior can mitigate against treatment degradation when treatment errors occur and provided support for the utility of considering parameters of reinforcement when developing behavioral interventions for problem behavior.

Further evaluation of contingency modeling to increase consumption of nutritive foods in children with autism and food selectivity

AbstractResearch suggests contingency modeling with differential reinforcement of alternative behavior can increase consumption of nonpreferred foods in some children with feeding problems. The current study further evaluated the effectiveness of this treatment with three children with food selectivity and autism. Participants first observed a positive reinforcement contingency in which the confederate model accessed preferred items and edibles contingent on consuming all of the target foods on their plate. If the participant imitated the model and consumed all of their food, they too received access to the same preferred items and edibles. When this contingency was ineffective for two participants, the confederate and feeder modeled nonremoval of the spoon, which increased consumption for both participants. We conclude with a discussion of potential underlying mechanisms for the effects and future research.

A brief assessment of pica

AbstractThe settings and procedures described in published studies focused on assessing and treating pica may not be relatable or feasible for all practitioners. This brief report demonstrates a successful replication of modified methods for assessing and treating a 16‐year‐old diagnosed with Autism Spectrum Disorder who engaged in pica. The study extended the existing research on pica in the following ways: First, it supported the utility of brief analysis methods, including brief functional analysis (FA) sessions, fewer FA sessions, and a preference assessment requiring less time to complete. Second, it described an FA for pica in a home setting. Finally, it evaluated the utility of differential reinforcement of alternative behavior in the form of mands in treating pica.

Resurgence Following Traditional and Interdependent Differential Reinforcement of Alternative Behavior.

Clinicians frequently prescribe functional communication training (FCT) as a treatment for severe destructive behavior. Recent research has shown that FCT treatments are susceptible to treatment relapse in the form of resurgence of destructive behavior when individuals contact periods in which reinforcers are unavailable. Results of preliminary studies suggest that teaching multiple response alternatives can mitigate the resurgence of target behavior. The current evaluation serves as a preliminary study in which we used a laboratory arrangement to evaluate the effects of a novel approach to training multiple alternative responses on the resurgence of target behavior. Findings showed that multiple-response training did not decrease resurgence of target responding consistently; however, it increased the total amount of target and alternative responding observed during the resurgence phase and decreased the overall probability of the target response.

A comparison of brief and extended session duration functional analyses.

Many behavior analysts do not conduct a functional analysis (FA) prior to treatment in a clinical setting (e.g., Roscoe et al.,2015). When asked for an explanation, respondents commonly report that an FA is too time consuming. One way to address this perceived constraint is to evaluate the utility of an abbreviated FA with 5-min session durations. In the current study, 2 independent FAs, 1 with 5-min sessions and 1 with 10-min sessions, were conducted for the problem behavior of 5 individuals diagnosed with autism spectrum disorder (ASD). For all participants, the 5- and 10-min session duration FAs yielded the same identified function of problem behavior: escape from demands. A brief differential reinforcement of alternative behavior (DRA) analysis was subsequently conducted and found to be effective at decreasing problem behavior and increasing an appropriate communication response across participants. These findings demonstrate the utility of conducting an FA using briefer session durations followed by a brief DRA analysis.

Effects of response cost magnitude on resurgence of human operant behavior

Extensive research has been dedicated to the study of resurgence following extinction and differential reinforcement of alternative behavior. Less is known about the effects of punishment on resurgence. This study extended previous research by examining whether the magnitude of response cost punishment affects resurgence of human operant behavior. College students engaged in a computer task using the three-phase resurgence procedure where points were used to reinforce target (Phase 1) or alternative (Phase 2) behavior. Across three groups, Phase 2 contingencies for the target response were manipulated. In one group, only extinction was implemented. In the other two groups, response cost was also implemented. Response cost was equal to or double the number of points that could be gained for alternative responding. Resurgence was similar in Phase 3 across the three groups, demonstrating that neither the addition nor the magnitude of punishment differentially affected response recovery under these conditions. Future research should examine other parameters of punishment (e.g., delay, schedule) and how these variables interact with different parameters of alternative reinforcement to increase our understanding of the conditions under which resurgence may be exacerbated or minimized.

On the definition of differential reinforcement of alternative behavior.

Differential reinforcement of alternative behavior (DRA) has a long history as a behavioral treatment. The term has usually been defined in a manner that suggests one form of behavior (usually some appropriate alternative) is reinforced, while another form of behavior (usually problem behavior) is placed on extinction. In this paper, we will suggest that DRA should not require extinction, either procedurally or by definition. Ideally, problem behavior would be placed on extinction when possible; however, when problem behavior is not or cannot be placed on extinction, the procedure used is still DRA. Thus, we propose the following definition: Providing greater reinforcement, along at least one dimension, contingent on the occurrence of one form or type of behavior, while minimizing reinforcement for another form or type of behavior.

Increasing item engagement and decreasing automatically reinforced problem behavior within a modified competing stimulus assessment.

A competing stimulus assessment (CSA) is commonly used to identify leisure items for use in treatments designed to decrease automatically reinforced problem behavior. However, this type of assessment may not yield useful information if participants do not readily engage with leisure items. The purpose of this study was to evaluate a modified CSA that included additional treatment components (i.e., prompting, prompting plus differential reinforcement of alternative behavior). The modified CSA identified the treatment components and leisure items that were most effective for increasing leisure-item engagement and decreasing problem behavior for each participant. Modified CSA outcomes maintained during an extended treatment analysis in a natural setting and when intervention components were faded.
