Renewal gives an experimental model for the relapse of fear symptoms following exposure therapy. While renewal of extinguished fear in humans has been observed following a return to the original context in which fear was acquired (ABA design), it has been more difficult to show upon presentation of a novel context (ABC design). The present experiment used a particularly strong context manipulation in a fear conditioning procedure. Context was manipulated by using large photographs of real environments taken from various angles and was present throughout the entire experiment. A renewal of cognitive expectancy was found in both ABA and ABC renewal designs, although it was larger in the former than in the latter. Response times in making the expectancy judgments increased when there was a change to a new context. The results demonstrate consistency in fear renewal effects between human and animal studies and suggest that relapse following exposure therapy via renewal remains a danger when people encounter a previously feared object in a novel context.
更新为暴露疗法后恐惧症状复发提供了一个实验模型。虽然在人类中已经观察到在回到最初获得恐惧的情境中（ABA 设计）时，已消除的恐惧会重新出现，但在呈现新情境时（ABC 设计）则更难观察到。本实验在恐惧条件反射程序中使用了一种特别强烈的情境操作。通过使用从不同角度拍摄的真实环境的大照片来操纵情境，并且整个实验过程中都存在情境。在 ABA 和 ABC 更新设计中都发现了认知预期的更新，尽管前者比后者更大。当环境变化到新环境时，做出预期判断的反应时间会增加。结果表明，人类和动物研究中的恐惧更新效应具有一致性，并且表明当人们在新情境中遇到以前恐惧的物体时，通过更新来进行暴露疗法后的复发仍然是一种危险。
