背景：先前的研究将侵入性认知（幻觉和强迫症）与抑制性失调联系起来。有意抑制和背景记忆的组合缺陷已经被提出来解释幻听的侵入性和感知的非自我起源（沃茨等人，2006年）。本研究测试了预测，从这个模型，即强迫症（OCD）的个人，谁不错误的起源，他们的侵入性思想，将显示出赤字的故意抑制，但完整的contextual memory.METHOD：14个人与强迫症和24名健康对照组的表现进行了比较，在两个措施的故意认知抑制和contextual memorytask.Results。强迫症的参与者显着受损的抑制措施，但没有显着不同的控制在任何条件下的上下文记忆task.CONCLUSIONS：预测得到证实。强迫症患者，像精神分裂症患者的幻听，表现出受损的故意抑制。这种损害可能是负责侵入性的想法在这两种疾病的报告，也可能部分占强迫症和精神分裂症的共病率高。最后，强迫症患者完整的上下文记忆能力可能有助于建立一个有效的记忆系统，并可能将这一群体与那些有幻觉的人区分开来。
BACKGROUND: Previous studies have linked intrusive cognitions (hallucinations and obsessions) with inhibitory dysregulation. Combined deficits in intentional inhibition and context memory have been proposed to explain the intrusive nature and perceived nonself origin of auditory hallucinations (Waters et al., 2006). This study tested the prediction, from this model, that individuals with obsessive-compulsive disorder (OCD), who do not mistake the origin of their intrusive thoughts, will show a deficit of intentional inhibition but intact contextual memory.METHOD: The performance of 14 individuals with OCD and 24 healthy controls was compared on two measures of intentional cognitive inhibition and on a context memory task.Results. Participants with OCD were significantly impaired on both measures of inhibition but were not significantly different from controls in any condition of the context memory task.CONCLUSIONS: The predictions were confirmed. Individuals with OCD, like schizophrenia patients with auditory hallucinations, showed impaired intentional inhibition. This impairment might be responsible for the intrusive thoughts reported in both disorders, and might also partially account for the high rates of comorbidity of OCD and schizophrenia. Finally, intact context memory abilities in OCD may contribute to an efficient memory system, and may differentiate this group from those with hallucinations.
