Providing a short break contingent on completed work may increase responding through positive reinforcement (e.g., access to preferred activities) or negative reinforcement (e.g., escape form work). In this investigation, three analyses conducted with a boy with profound mental retardation showed that (a) a 20-s break increased responding more than a positive reinforcer (cola) did, and (b) the reinforcing effect of a 20-s break were affected by the availability of positive reinforcers during the break were affected by the availability of positive reinforcers during the break.
根据已完成的工作给予短暂休息,可能会通过正强化(例如,获得喜欢的活动)或负强化(例如,从工作中解脱)来增加反应。在本研究中,对一名重度智力障碍男孩进行的三项分析表明:(a)20秒的休息比正强化物(可乐)更能增加反应;(b)20秒休息的强化效果受到休息期间正强化物可用性的影响。
