We evaluated the effects of a response-effort intervention on the occurrence of self-injurious hand mouthing and a competing response (object manipulation) with 4 individuals who had profound developmental disabilities. During Phase 1, results of functional analyses showed that all participants engaged in high levels of hand mouthing in the absence of social contingencies, suggesting that the behavior was maintained by automatic reinforcement. In Phase 2, preferred leisure items were identified for participants during assessments in which duration of leisure item manipulation was used as the index of preference. In Phase 3, participants were observed to engage in high levels of hand mouthing and in varying levels of object manipulation when they had free access to their most preferred leisure items during baseline. The effects of increased response effort on hand mouthing and object manipulation were then evaluated in mixed multiple baseline and reversal designs. The response-effort condition was identical to baseline, except that participants wore soft, flexible sleeves that increased resistance for elbow flexion but still enabled participants to engage in hand mouthing. Results showed consistent decreases in SIB and increases in object manipulation during the response-effort condition for all participants. These results suggested that a less preferred reinforcer (produced by object manipulation) may substitute for a more highly preferred reinforcer (produced by hand mouthing) when response effort for hand mouthing was increased.

Lattal and Perone's Handbook of methods used in human operant research on behavioral processes will be a valuable resource for researchers who want to bridge laboratory developments with applied study. As a supplemental resource, investigators are also encouraged to examine the series of papers in the Journal of Applied Behavior Analysis that discuss basic research and its potential for application. Increased knowledge of behavioral processes in laboratory research could lead to innovative solutions to practical problems addressed by applied behavior analysts in the home, classroom, clinic, and community. 相似文献

An adolescent with severe mental retardation and cerebral palsy who displayed attention-maintained destructive behavior was exposed to noncontingent reinforcer delivery (NCR) with either a high-preference or a low-preference stimulus while reinforcement for destructive behavior with attention remained in effect (i.e., NCR without extinction). NCR without extinction was effective only when the high-preference stimulus was available, suggesting that systematic assessment of stimulus quality may enhance the effectiveness of NCR with alternative stimuli. 相似文献

Noncontingent reinforcement (NCR) consists of delivering a reinforcer on a time-based schedule, independent of responding. Studies evaluating the effectiveness of NCR as treatment for problem behavior have used fixed-time (FT) schedules of reinforcement. In this study, the efficacy of NCR with variable-time (VT) schedules was evaluated by comparing the effects of VT and FT reinforcement schedules with 2 individuals who engaged in problem behavior maintained by positive reinforcement. Both FT and VT schedules were effective in reducing problem behavior. These findings suggest that VT schedules can be used to treat problem behavior maintained by social consequences. 相似文献

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. 相似文献

A primary characteristic of autism spectrum disorder includes restrictive and repetitive patterns of behavior. Because having few preferred items and activities can lead to social, communicative, and educational barriers, it is important to increase the number of preferred stimuli in the individual's environment. One way to do this is through conditioned reinforcement via observation. Such procedures involve the acquisition of a skill or change in behavior as a result of indirect contact (i.e., observation) with contingencies received by others. While conditioning through observation has been shown to be effective, one novel approach is video self-modeling. The purpose of the current study was to assess the effects of video self-modeling on the preference and reinforcer value of toys for children diagnosed with autism spectrum disorder. 相似文献

Deficits in social communication and restricted, repetitive patterns of behavior or interests are displayed by individuals with autism spectrum disorder (ASD; American Psychiatric Association, 2013). Given this, individuals with ASD may engage with a limited variety of reinforcers. Treatments designed to modify the distribution of manding may allow individuals to contact a broad array of reinforcers that could improve the quality of life for individuals with ASD (Seaver & Bourret, 2020). The purpose of the current study was to replicate the results of Seaver and Bourret (2020) by evaluating the effects of manipulating concurrent schedules of reinforcement, alone and with prompts, on the rates of target manding in three boys with ASD, aged 7–9 years, in the United Arab Emirates. All three participants showed increased target manding following intervention. The findings support the use of concurrent reinforcement schedules and prompts as an effective intervention to produce varied manding. 相似文献

This study analyzed the effects of nursing assistants' use of prompts and praise to increase the engagement of older adults with dementia in daily living activities. The multiple baseline design across morning and afternoon work shifts showed consistent increases in engagement by each of the 5 residents during the intervention. These results suggest that increasing prompts and praise by nursing assistants may, in turn, increase the rate of engagement of older adults with dementia. 相似文献

Wandering behavior of 4 geriatric patients with dementia residing in a long-term care facility was assessed using direct behavioral observations. The consequences identified during the observations as maintaining wandering for each patient were then applied for the absence of wandering using differential reinforcement of other behavior (DRO). The effectiveness of the DRO procedure was evaluated using an ABAB design. Results indicated significant reductions in wandering during treatment. 相似文献

We conducted several comparative analyses to determine the relative effectiveness of variable-momentary differential-reinforcement-of-other-behavior (VM DRO) schedules. Three individuals who had been diagnosed with mental retardation participated. Results of functional analyses indicated that their self-injurious behavior (SIB) was maintained by social-positive reinforcement. Two individuals participated in a two-stage comparative analysis within multielement and multiple baseline designs. Fixed-interval (FI) and variable-interval (VI) DRO were compared in the first stage; VI DRO and VM DRO were compared in the second. All three schedules effectively reduced the participants' SIB. Treatment for the 3rd individual was conducted in a reversal design to examine the effects of VM DRO when it was implemented in isolation, and results indicated that the procedure was effective in reducing SIB. These findings suggest that VM DRO schedules may represent attractive alternatives to traditional FI schedules because momentary schedules do not require continuous monitoring and may result in higher rates of reinforcement. 相似文献
