We evaluated a multiple schedule in which the extinction (S-) components were signaled overtly by a black lanyard and the reinforcement (S+) components were not correlated with any programmed stimuli in developing stimulus control over the high-rate social-approach responses of an adult with mental retardation. Responding was consistently low in the presence of the S- and consistently high when the lanyard was absent (i.e., the S+ condition). Component durations were thinned successfully to a level that was manageable for caregivers.
我们评估了一种多重时间表,其中消退(S-)成分通过黑色挂绳进行明显的信号指示,而强化(S+)成分与任何程序刺激均不相关,以此在发展对具有智力障碍的成年人的高反应率社交趋近反应的刺激控制方面进行干预。在 S-存在的情况下,反应始终较低,而当挂绳不存在时(即 S+条件),反应始终较高。组件持续时间成功地减少到可由护理人员管理的水平。
