Typically, functional analyses of severe problem behavior have been conducted in two ways: (a) The target response is reinforced immediately after it occurs, or (b) the target response is reinforced on some schedule thought to mimic a naturally occurring schedule. We evaluated the effects of contingency strength in reducing levels of problem behavior with 2 participants who had been diagnosed with developmental disabilities. Results showed that under a neutral contingency, one in which the probability of reinforcement for aggression was equal to the probability of reinforcement for the nonoccurrence of aggression, rates of aggression were suppressed to low levels for both participants.
通常,对严重问题行为的功能分析采用两种方式进行:(a) 目标反应出现后立即给予强化,或者 (b) 按照某种被认为模拟自然发生模式的时间表给予目标反应强化。我们评估了2名被诊断为发育障碍的参与者在降低问题行为水平方面的应急强度效应。结果表明,在中性应急情况下,即攻击行为得到强化的概率与无攻击行为得到强化的概率相等时,两名参与者的攻击行为发生率均被抑制到较低水平。
