Previous research has documented high trait cognitive self-consciousness (CSC) in obsessive-compulsive disorder (OCD). It remains unclear whether elevated CSC levels can also explain cognitive performance deficits that have frequently been found in OCD. This study examined whether experimentally heightened CSC affects visual memory performance in OCD. OCD participants and healthy controls completed a complex figure test under three experimental conditions: simultaneously focusing on their thoughts (= CSC condition), simultaneously focusing on acoustic stimuli (= dual-task condition), and without a parallel task (= standard condition). In the OCD sample both the CSC condition and the dual-task condition reduced memory performance compared to the standard condition, whereas in controls only the dual-task condition led to reduced performance. Results indicate that raising CSC in OCD has a deteriorating effect on memory encoding that parallels the effect of a secondary task. High CSC and its effects on cognitive performance might be amenable to meta-cognitive treatment approaches.
先前的研究已经证明，强迫症（OCD）患者具有较高的特质认知自我意识（CSC）。目前尚不清楚升高的 CSC 水平是否也可以解释 OCD 患者经常出现的认知表现缺陷。本研究旨在检验实验中升高的 CSC 是否会影响 OCD 患者的视觉记忆表现。OCD 患者和健康对照组在三种实验条件下完成了复杂图形测试：同时关注自己的想法（=CSC 条件）、同时关注声音刺激（=双重任务条件）和不进行平行任务（=标准条件）。在 OCD 样本中，CSC 条件和双重任务条件都导致记忆表现较标准条件下降，而在对照组中，只有双重任务条件会导致记忆表现下降。结果表明，在 OCD 中升高 CSC 会对记忆编码产生恶化作用，这种作用类似于次要任务的作用。高 CSC 及其对认知表现的影响可能适合元认知治疗方法。
