This paper describes two experiments designed to investigate how a current model of task perseveration, the mood-as-input hypothesis, might be applied to activities relevant to compulsive checking. The mood-as-input hypothesis predicts that perseveration at an open-ended task will be determined by a combination of the "stop rules" adopted for the task, and the valency of the mood state in which the task is conducted. Experiment 1 required participants to generate items that should be checked for safety/security if they were leaving their home unattended. Experiment 2 used an analogue recall task, in which participants were asked to recall items from a comprehensive list of items that should be checked if they were to leave their home safe/secure. Both experiments found that perseveration at the tasks was determined by particular configurations of mood and stop rules for the task. Of most relevance to compulsive checking was the fact that facilitated perseveration occurred when participants were asked to undertake the tasks in a negative mood using "as many as can" stop rules. Implications for the factors that develop and maintain compulsive checking are discussed.
本文描述了两项实验，旨在探究当前一种关于任务固执的模型——情绪输入假说，如何应用于与强迫性检查相关的活动。情绪输入假说预测，在开放性任务上的固执将由该任务所采用的“停止规则”以及执行任务时情绪状态的效价共同决定。实验1要求参与者生成一些物品，如果他们要无人看管地离开家，就应对这些物品进行安全检查。实验2使用了一个类似回忆的任务，要求参与者从一份全面的物品清单中回忆，如果他们要安全离开家，应该检查哪些物品。两项实验均发现，任务中的固执由情绪和任务停止规则的特定组合所决定。与强迫性检查最相关的是，当要求参与者在消极情绪下使用“尽可能多”的停止规则来执行任务时，会出现促进固执的情况。本文还讨论了对导致和维持强迫性检查的因素的启示。
