Children with autism spectrum disorder and other developmental disabilities often exhibit invariant responding (i.e., restricted behavioral repertoires), deficits in communication, and challenging behavior. Approaches demonstrated in the basic and applied literature to increase response variability include extinction, lag schedules of reinforcement, and percentile schedules of reinforcement. Results of basic studies have also indicated that delays to reinforcement often produce increases in response variability. The purpose of the current study was to evaluate the effects of a delay to reinforcement on the variability of communication responses during functional communication training with individuals with developmental disabilities and histories of engaging in challenging behavior. Results indicated that delays to reinforcement increased mand variability with all four participants with variable effects on challenging behavior across participants.
患有自闭症谱系障碍和其他发育障碍的儿童通常表现出固定反应（即行为模式受限）、沟通缺陷和具有挑战性的行为。基础和应用文献中证明的增加反应变异性的方法包括消退、强化的滞后时间表和强化的百分位数时间表。基础研究的结果还表明，强化延迟通常会导致反应变异性增加。本研究的目的是评估强化延迟对发育障碍且有挑战行为史的个体进行功能性沟通训练期间沟通反应变异性的影响。结果表明，强化延迟增加了所有四名参与者的要求变异性，对不同参与者的挑战行为产生了不同影响。
