Physical inactivity has increasingly affected public health in the United States during the COVID-19 pandemic as it is associated with chronic diseases such as arthritis, cancer, and heart disease. Contingency management has been shown to increase physical activity. Therefore, the present study sought to evaluate the effects of an escalating schedule of monetary reinforcement with a reset contingency on physical activity, as compared between 2 counterbalanced groups in which a monetary deposit of $25 was either required (deposit group) or not (no-deposit group). Twenty-five adults wore Fitbit accelerometers to monitor step counts. An ABA reversal design was used; in the 2 baseline phases, no programmed contingencies were in place for step counts. During intervention, step goals were set using a modified 70th percentile schedule with a 7-day window: Reaching the first goal would result in $0.25, and incentives increased by $0.25 for each subsequent day in which the goal was met. Failure to reach a goal resulted in a reset of the monetary incentive value to $0.25. Ten out of 12 participants from the deposit group were determined to be responders to intervention, whereas 8 out of 13 participants from the no-deposit group were determined to be responders to intervention. Overall, there were no significant differences between the groups' step counts. However, the deposit group's intervention was cheaper to implement, which suggests that deposit contracts are a viable modification for physical activity interventions. 相似文献

Hardly anyone denies that (nearly) all human beings have equal moral status and therefore should be considered and treated as equals. Yet, if humans possess the property that confers moral status upon them to an unequal degree, how come they should be considered and treated as equals? It has been argued that this is because the variations in the degree to which the status-conferring property is held above a relevant threshold are contingencies that do not generate differences in degrees of moral status. Call this the contingency argument for the basis of moral equality. In this paper, I reject the contingency argument. Instead, I develop an attitude-based account of the basis of moral equality: according to this account, the basis of moral equality lies in a fitting, basic, and independent moral attitude which is owed to human beings qua moral status-holders, and provides a coherent and plausible explanation for why the variations above the threshold for moral status do not matter. 相似文献

In two laboratory experiments, we examined whether stimuli paired with alternative reinforcers could mitigate resurgence of a previously reinforced target response with pigeons (Experiment 1) and children diagnosed with Autism Spectrum Disorder (Experiment 2). In Phase 1, we arranged food reinforcement according to a variable-ratio schedule for engaging in a target response. In Phase 2, we arranged extinction for target responding and differentially reinforced alternative responding according to a fixed-ratio schedule, with every alternative-reinforcer delivery paired with a change in keylight color (Experiment 1) or automated verbal (praise) statement (Experiment 2). In Phase 3, we assessed resurgence during extinction of target and alternative responding in the presence versus absence of continued presentation of the paired stimulus. Despite variation across sessions, resurgence on average was lower when continuing to present the paired stimuli in all pigeons and children while maintenance of alternative responding did not differ between assessments. These findings indicate that stimuli paired with alternative reinforcement can modestly decrease resurgence, but further examination of their efficacy and a better understanding of the underlying processes are necessary before they can be recommended for clinical use in reducing resurgence of clinically relevant problem behavior. 相似文献

Recent research suggests that combining putative reinforcers for problem behavior into a single, synthesized contingency may increase efficiency in identifying behavioral function relative to traditional functional analysis (FA). Other research suggests potential shortcomings of synthesized contingency analysis (SCA), such as the potential for false-positive outcomes. In prior comparisons of traditional FAs and SCAs, investigators could not ascertain with certainty the true function(s) of the participants' problem behavior for use as the criterion variable. We conducted a translational study to circumvent this limitation by training a specific function for a surrogate destructive behavior prior to conducting a traditional FA and SCA. The traditional FA correctly identified the previously established function of the target response in all six cases and produced no iatrogenic effects. The SCA produced differentiated results in all cases and iatrogenic effects (i.e., an additional function) in three of six cases. We discuss these findings in terms of the mechanisms that may promote iatrogenic effects. 相似文献

Adults with developmental disabilities are less likely to meet physical activity guidelines than typically developing counterparts. Contingency management (CM) interventions increase physical activity in sedentary adults. The current study systematically replicated previous research among sedentary adults diagnosed with developmental disabilities living in a residential group home, using a token economy in the context of a CM intervention. Using a changing criterion design, participants (N = 4) were given tokens contingent on meeting increasing step goals over 8 weeks, tracked via a Fitbit Flex?. CM increased the number of steps substantially for three of four participants. These findings extend previous research supporting the use of token‐based CM interventions for increasing daily steps among individuals with developmental disabilities. Because the current study was conducted in a residential group home setting, it may offer a long‐term sustainable approach to improving the health of some individuals living with developmental disabilities. 相似文献

The generality and long-term maintenance of a pairing procedure designed to improve the efficacy of less intrusive procedures were evaluated for the treatment of problem behavior maintained by automatic reinforcement exhibited by 2 individuals with developmental disabilities. Results suggested that a less intrusive procedure could be established as a conditioned punisher by pairing it with an effective punisher contingent on problem behavior. Generalization across multiple therapists was demonstrated for both participants. However, generalization to another setting was not achieved for 1 participant until pairing was conducted in the second setting. Long-term maintenance was observed with 1 participant in the absence of further pairing trials. Maintenance via intermittent pairing trials was successful for the other participant. 相似文献

自我价值感权变性是近年在西方关于自尊的研究中出现的新概念。为了探讨自我价值感权变性的作用和性质,特别是其对行为产生的调控作用,以90名大学本科生为被试进行测验,Logistic回归分析显示,在控制了自我价值感、性别、家庭所在地等变量的情况下,自我价值感权变性对被试的活动或任务选择产生显著影响。结果表明,自我价值感权变于个人目标的个体较少愿意参加助人活动,较少选择难度大但有利自身成长的任务。 相似文献

Three experiments were conducted with rats in which responses on one lever (labeled the functional lever) produced reinforcers after an unsignaled delay period that reset with each response during the delay. Responses on a second, nonfunctional, lever did not initiate delays, but, in the first and third experiments, such responses during the last 10 s of a delay did postpone food delivery another 10 s. In the first experiment, the location of the two levers was reversed several times. Responding generally was higher on the functional lever, though the magnitude of the difference diminished with successive reversals. In the second experiment, once a delay was initiated by a response on the functional lever, in different conditions responses on the nonfunctional lever either had no effect or postponed food delivery by 30 s. The latter contingency typically lowered response rates on the nonfunctional lever. In the first two experiments, both the functional and nonfunctional levers were identical except for their location; in the third experiment, initially, a vertically mounted, pole-push lever defined the functional response and a horizontally mounted lever defined the nonfunctional response. Higher response rates occurred on the functional lever. These results taken together suggest that responding generally tracked the response-reinforcer contingency. The results further show how nonfunctional-operanda responses are controlled by a prior history of direct reinforcement of such responses, by the temporal delay between such responses and food delivery, and as simple generalization between the two operanda. 相似文献

We evaluated the differential effects of 2 variations of a stimulus–stimulus pairing procedure on the vocalizations of 2 children with autism. For both participants, presenting 1 sound per pairing trial resulted in a higher rate of vocalizations than 3 sounds per pairing trial. 相似文献
