The authors hypothesize that the symptoms of obsessive-compulsive disorder (OCD), despite their apparent nonrationality, have what might be termed an epistemic origin--that is, they stem from an inability to generate the normal "feeling of knowing" that would otherwise signal task completion and terminate the expression of a security motivational system. The authors compare their satiety-signal construct, which they term yedasentience, to various other senses of the feeling of knowing and indicate why OCD-like symptoms would stem from the abnormal absence of such a terminator emotion. In addition, they advance a tentative neuropsychological model to explain its underpinnings. The proposed model integrates many previous disparate observations and concepts about OCD and embeds it within the broader understanding of normal motivation.
作者们推测，尽管强迫症（OCD）的症状表面上不合理，但它们可能有认知根源——也就是说，它们源于无法产生正常的“知晓感”，否则这种感觉会标志任务完成并终止安全动机系统的表达。作者们将他们称为“饱足感信号”的结构（即“yedasentience”）与其他各种知晓感进行比较，并指出类似强迫症的症状为何会源于这种终止性情绪的异常缺失。此外，他们还提出了一个初步的神经心理学模型来解释其基础。该模型整合了许多先前关于强迫症的不同观察和概念，并将其置于对正常动机的更广泛理解之中。
