Noncontingent Reinforcement Research Articles

Noncontingent reinforcement in the treatment of pediatric feeding disorder: A concise review.

This concise review summarizes the literature on noncontingent reinforcement in the treatment of pediatric feeding disorder from 2018 to 2022. We reviewed 15 published behavior-analytic feeding studies to identify how often the term noncontingent reinforcement is used, what form of noncontingent reinforcement is delivered, and what the effects of noncontingent reinforcement are on behavior when it is included in treatment. Implications and directions for future research are discussed.

Effects of contingent and noncontingent reinforcement on the emotional behavior of domestic dogs (Canis familiaris)

Intermittent schedules of reinforcement are frequently used in dog training. During fixed-time (FT) schedules, reinforcement delivery is time-based and response-independent. In contrast, during fixed-interval (FI) schedules, a response produces a reinforcer if a certain amount of time has elapsed since the last reinforcer was delivered (i.e., FI schedules are time-based and response-dependent). FT schedules are typically used in noncontingent-reinforcement interventions with the aim of decreasing an undesired behavior. Although the effectiveness of these interventions has been reliably shown with human and nonhuman animal learners, little is known about the emotional behavior that is related to these contingencies. In the present study, the target behavior (stepping on a mat) of six dogs was initially trained (shaped) and maintained on a FI 15s schedule. In addition, dogs were exposed to a FT 15s schedule, a combination of FT 15s and FI 15s schedules, and an extinction-only condition (no reinforcement was delivered for the target response). We found that rates of emotional responses (e.g., lip/nose licking, vocalizing) varied in prevalence across dogs and phases. Although lip/nose licking was displayed in high rates across all dogs and phases, it was generally lower in baseline and extinction phases. This suggests that these phases produced less frustration-related behavior. The effect-size calculations for dogs engaging in pacing, sneezing, and vocalizing underscored the varied prevalence of the behaviors across phases and dogs and yielded mostly small- to medium-size effects. These results are especially relevant for the training of companion and working dogs and their well-being during training sessions. Future research should continue investigating emotional behavior in dogs across various schedules of reinforcement (e.g., variable schedules).

Evaluation of an automated response-independent schedule on the behavioral welfare of shelter dogs.

Response-independent schedules involve the delivery of an item independent of a response requirement. Often described in the applied behavior analytic literature as "noncontingent reinforcement," they have also frequently been used to reduce undesired or problematic behaviors. The current study examined the use of an automated response-independent food schedule on the behaviors and sound levels of shelter dogs. Several dogs were included in a 6-week reversal design, where a fixed-time 1 min schedule was compared with a baseline condition. Eleven behaviors were measured, as were two areas of each kennel and the overall and session sound intensity (dB) that occurred during the study. The results demonstrated that the fixed-time schedule increased overall activity while decreasing inactivity and led to a reduction in the overall sound intensity measured. Session and hour-to-hour sound-intensity data were less clear, suggesting a potential contextual conditioning effect as well as a need for adjusted methods to study shelter sound. The above are discussed in terms of their potential welfare benefits for shelter dogs as well as the translational approach that this and similar research could contribute to the application and functional understanding of response-independent schedules.

Bridging the gap between laboratory and applied research on response-independent schedules.

In 1948, Skinner described the behavior of pigeons under response-independent schedules as "superstitious," and proposed that the responses were reinforced by contiguous, adventitious food deliveries. Subsequently, response-independent schedules have been of interest to both basic and applied researchers, first to understand the mechanisms involved, and later, as "noncontingent reinforcement" (NCR) to reduce undesirable behavior. However, the potential superstitious effects produced by these schedules have been challenged, with some researchers arguing that antecedent variables play a significant role. This paper examines the evidence for adventitious reinforcement from both laboratory and applied research, the results of which suggest that antecedent, nonoperant functions may be important in fully understanding the effects of NCR. We propose an applied-basic research synthesis, in which attention to potential nonoperant functions could provide a more complete understanding of response-independent schedules. We conclude with a summary of the applied implications of the nonoperant functions of NCR schedules.

The effects of noncontingent reinforcement on an arbitrary response in domestic dogs (Canis lupus familiaris)

Noncontingent reinforcement (NCR) procedures entail the response-independent, time-based delivery of a reinforcer (e.g., delivery of a reinforcer on a fixed-time 15 s schedule – FT 15 s). Although NCR has been demonstrated to be effective for the treatment of undesired behaviours in human learners, very few studies have examined it in nonhuman animals. We investigated how NCR with and without extinction (another well-studied behavioural intervention) affected an arbitrary response in companion dogs. The ‘stepping on a rug’ response was shaped and established in lieu of a problem behaviour in six dogs. Stepping was then exposed to fixed-interval (FI 15 s), fixed-time (FT 15 s), a combination of these schedules of reinforcement (FT 15 s + FI 15 s), and an extinction-only condition. The results indicated that NCR was effective in reducing the target behaviour in three out of the six dogs. These effects were greater in the NCR-with-extinction procedure than in the NCR-without-extinction condition. Future research should investigate the effects of schedule thinning and other schedules of reinforcement (e.g., variable-time schedules) on the behaviour of companion dogs.

The effects of noncontingent reinforcement on task disengagement following failure of differential reinforcement treatment

AbstractFollowing the failure of applications of differential reinforcement (DR), the effects of reinforcement delivered noncontingently (NCR) on task disengagement and task completion were evaluated within reversal designs for three children with autism spectrum disorder. In Experiment 1, we compared DR and NCR schedules that combined positive and negative reinforcement. In Experiment 2, we replicated the results of Experiment 1 and then evaluated NCR schedules composed solely of negative reinforcement and NCR schedules that combined negative reinforcement with high‐or low‐preferred stimuli. In Experiment 3, we further analyzed NCR schedules that included different types and qualities of positive reinforcement, but without the inclusion of negative reinforcement. The results showed that NCR schedules using positive reinforcers can be effective as a treatment for task disengagement, but the type and preference of the reinforcer can alter effectiveness. These results are interpreted in terms of the motivating operations associated with task disengagement.

Multiple Schedules Facilitate Rapid Noncontingent Reinforcement Schedule Thinning.

We evaluated a noncontingent reinforcement treatment that included initial brief exposures to signaled alternation of availability and nonavailability of reinforcement, followed by rapid schedule thinning. Results confirmed findings from previous research (typically with differential reinforcement schedules) that establishing stimulus control across multiple treatment components facilitated schedule thinning. We discuss both the clinical utility of this procedure and the utility of stimulus control for making interventions more practical for clinicians.

Reducing the occurrence of mouthing and jumping in a dog through conditional discrimination training.

Many approaches for reducing unwanted behavior use punishment, extinction, or noncontingent reinforcement. Other methods focus on teaching and reinforcing alternative behaviors that can replace the unwanted behavior. Another strategy can be to change the stimulus control of the unwanted behavior. The present study investigated if conditional discrimination training using positive reinforcement could reduce undesirable behaviors in a pet dog. After conditional discrimination training, two unwanted behaviors (jumping and mouthing) occurred reliably in the presence of new discriminative stimuli, while other behaviors occurred in the presence of the discriminative stimuli that had previously produced these unwanted behaviors. This experiment demonstrates that conditional discrimination training can be an effective way to control the frequency of an unwanted behavior by controlling the frequency of the presentation of a discriminative stimulus.

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.

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.

Remote Training of Dental Students and Professionals to Promote Cooperative Behavior in Patients with Intellectual and Developmental Disabilities.

Many individuals diagnosed with intellectual and developmental disabilities (IDD) are uncooperative during routine dental exams, leading to poor oral health in this population. Few studies have evaluated methodologies for preparing dental students and professionals to work effectively with patients diagnosed with IDD. In this study, experimenters used remote behavioral skills training (BST) to train dental students and professionals how to implement a practical intervention that included tell-show-do, contingent praise, and noncontingent reinforcement. Results suggested that group training conducted via videoconferencing was effective for teaching six of seven participants to implement the intervention in the absence of post-training feedback. This approach appears useful for quickly and efficiently training current and future dental professionals to implement behavior techniques to promote patient compliance.

Relapse after incentivized choice treatment in humans: A laboratory model for studying behavior change.

Behavior change interventions that incentivize desired behavior are highly effective for improving personal health, but difficult to maintain long term. Relapse is common and examining the mechanisms that contribute to relapse in experimental settings can identify processes relevant to substance abuse treatment. We developed a laboratory task that parallels a recent operant model of relapse after incentivized choice reported in the rodent laboratory. In two experiments, undergraduate participants first learned to make an operant response (keyboard button; R1) to earn a reinforcer consisting of an image of a preferred snack food (O1). In a second phase (Phase 2), R1 was still reinforced, but a new response (R2) was introduced and reinforced with a different reinforcer (a coin; O2). In a test phase, contingent incentives for R2 were removed (extinction) and relapse of R1 was assessed. Experiment 1 found that the O2 contingency suppressed R1 during Phase 2, and R1 relapsed rapidly in the test. Neither effect was consistently related to O2 value. Experiment 2 examined whether noncontingent presentations of O1 or O2 during the test could weaken relapse. Here, we found that noncontingent reinforcers did little to reduce or slow the increase in R1 responding. The present experiments highlight a laboratory approach to studying variables that may influence relapse after incentivized treatment. We identify and discuss areas for development to address differences between the present results and prior observations from animal and clinical studies.

Indices of happiness and unhappiness during treatment of pediatric feeding disorders

AbstractTo date, there is no research on the measurement of indices of happiness and unhappiness for children receiving behavior‐analytic treatment for feeding disorders and the research on caregiver treatment acceptability during feeding treatment is limited. The purpose of the current study was to measure child indices of happiness and unhappiness during extinction‐based treatment with and without noncontingent reinforcement and to evaluate caregiver treatment acceptability through the course of treatment. Child indices of happiness were idiosyncratic, while indices of unhappiness increased at the onset of treatment and were higher during extinction without noncontingent reinforcement, but eventually decreased. Overall, caregiver treatment acceptability remained high despite temporary increases in emotional responding. The current study introduces measures of social validity to use during feeding treatment (i.e., indices of happiness and unhappiness) and provides evidence that dense schedules of noncontingent reinforcement could serve to mitigate indices of unhappiness during the initial implementation of extinction‐based treatment.

On the generality of preference for contingent reinforcement

Reinforcers can be delivered dependent on or independent of responding. Both human and nonhuman animals have shown a preference for contexts involving contingent reinforcement, but the generality of this phenomenon to humans and its implications have not yet been described. We present an integrative summary of studies evaluating preference for contingent versus noncontingent reinforcement, including (a) study participants, reinforcer types, response topographies, and contexts; (b) outcomes; (c) potential variables influencing preference outcomes; and (d) suggestions regarding research to expand behavior analysts' ability to design preferred contexts.

Treatment Acceptability for Interventions Addressing Challenging Behavior Among Chinese Caregivers of Children with Autism Spectrum Disorder.

The present study evaluated treatment acceptability for behavioral interventions addressing challenging behaviors with Chinese caregivers of children with autism spectrum disorder. Factors influencing treatment acceptability (i.e., severity of challenging behavior and Chinese child-rearing values) were investigated. Caregivers of children aged 2-12years (N = 216) participated in this survey study. Results suggest that caregivers found positive strategies including noncontingent reinforcement and positive reinforcement the most acceptable; punishment-based strategies were rated as the least acceptable. Furthermore, positive punishment was perceived as more acceptable for severe challenging behavior. Caregivers who endorsed training were more likely to find positive strategies acceptable, whereas those who endorsed shaming were more likely to rate punishment-based strategies as more acceptable. Implications for future research and culturally competent behavioral treatments in Chinese context are provided.

Further evaluation of noncontingent reinforcement to treat mealtime problem behavior

AbstractWe evaluated the effects of noncontingent reinforcement (NCR) without escape extinction (EE) on problem behavior emitted by a young boy with autism spectrum disorder during meals. Results indicated that NCR (i.e., continuous access to a highly preferred activity) was effective in reducing problem behavior and moderately increasing food acceptance. Subsequently, we evaluated a total session‐based thinning of the NCR schedule. Although problem behavior remained low during schedule thinning, differential reinforcement was necessary to maintain adequate levels of food acceptance.
