Four surveys have shown that more than 80% of normal subjects have obsessive thoughts with content similar to those found in obsessive compulsive patients. "Abnormal" and "normal" intrusive thoughts do not differ in content but in duration, frequency and rejectability. Thirteen DSM III-R non-depressed obsessive compulsive patients with checking rituals were compared with 13 sex-, age-, and education matched control subjects. Our study compared the content of abnormal and normal obsessions. No between-group difference was found suggesting that a sub-group of obsessive compulsive patients with checking rituals did not change the general result. The memory processes were also compared. Several investigators have shown an impairment in visual spatial memory tasks but none in verbal tasks with obsessive compulsive patients. In three studies non clinical checkers were found to show some deficits in memory compared to non checkers. In our study we used the Wechsler memory scale. Clinical checkers appear to have difficulties recalling details of meaningfully linked verbal sequence and immediate visual reproduction.
四项调查显示，超过80%的正常受试者存在强迫观念，其内容与强迫症患者的相似。“异常”和“正常”的侵入性思维在内容上并无差异，只是在持续时间、频率和可拒绝性方面有所不同。将13名有检查仪式行为的DSM III-R非抑郁强迫症患者与13名性别、年龄和教育程度相匹配的对照受试者进行比较。我们的研究比较了异常和正常强迫观念的内容。未发现组间差异，这表明有检查仪式行为的强迫症患者亚组并未改变总体结果。同时也对记忆过程进行了比较。几位研究者发现强迫症患者在视觉空间记忆任务中存在损伤，但在言语任务中没有。在三项研究中，发现非临床检查者与非检查者相比在记忆方面存在一些缺陷。在我们的研究中，我们使用了韦氏记忆量表。临床检查者在回忆有意义关联的言语序列细节和即时视觉再现方面似乎存在困难。
