基础研究表明，行为持久性往往与强化率正相关。这种关系以行为动量的隐喻来表达，对临床应用具有潜在的重要意义。当前的研究检验了对自动强化行为的动量隐喻的一项预测。参与者是 3 名被诊断患有自闭症谱系障碍的儿童，他们通过自动强化维持刻板行为。结果表明，与不接受偏好刺激的时期相比，在可变时间安排上获得偏好刺激的时期，刻板行为更能抵抗破坏。讨论了这些发现对治疗自动强化行为的影响。
Basic research has shown that behavioral persistence is often positively related to rate of reinforcement. This relation, expressed in the metaphor of behavioral momentum, has potentially important implications for clinical application. The current study examined one prediction of the momentum metaphor for automatically reinforced behavior. Participants were 3 children who had been diagnosed with an autism spectrum disorder and who engaged in stereotypic behavior maintained by automatic reinforcement. Results suggested that stereotypic behavior was more resistant to disruption following periods of access to preferred stimuli delivered on a variable-time schedule than following periods without access to preferred stimuli. The implications of these findings for the treatment of automatically reinforced behavior are discussed.
