We evaluated the effects of noncontingent reinforcement (NCR) without escape extinction (EE) on problem behavior emitted by a young boy with autism spectrum disorder during meals. Results indicated that NCR (i.e., continuous access to a highly preferred activity) was effective in reducing problem behavior and moderately increasing food acceptance. Subsequently, we evaluated a total session‐based thinning of the NCR schedule. Although problem behavior remained low during schedule thinning, differential reinforcement was necessary to maintain adequate levels of food acceptance.

非偶然性补强对进餐时间问题行为的进一步评估

我们评估了未逃生灭绝（EE）的非临时性强化（NCR）对自闭症谱系障碍的年轻男孩进餐时发出的问题行为的影响。结果表明，NCR（即持续获得高度优先的活动）可有效减少问题行为并适度提高食品接受度。随后，我们评估了基于会话的NCR计划的总体精简。尽管在计划稀疏过程中问题行为仍然很低，但是必须采取差异加固措施以保持足够的食物接受水平。
