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.
非连续性强化（NCR）包括按照基于时间的时间表给予强化物，与反应无关。评估NCR作为问题行为治疗方法有效性的研究使用了固定时间（FT）强化时间表。在本研究中，通过比较可变时间（VT）和FT强化时间表对两名通过正强化维持问题行为的个体的影响，评估了NCR与VT时间表的疗效。FT和VT时间表在减少问题行为方面均有效。这些发现表明，VT时间表可用于治疗由社会后果维持的问题行为。
