BACKGROUND
Patients with basal ganglia abnormalities misclassify facial expressions of disgust as expressions of anger when asked to identify the emotion depicted in photographs of individuals displaying different emotions. Sprengelmeyer, Young, Pundt et al. (1997) reported a similar disgust recognition deficit in patients with obsessive-compulsive disorder (OCD)--an anxiety disorder associated with basal ganglia abnormality.
METHODS
In the present experiment, we attempted to replicate Sprengelmeyer, Young, Pundt et al.'s (1997) findings.
RESULTS
We failed to replicate Sprengelmeyer, Young, Pundt et al.'s finding of disgust recognition deficits in OCD patients relative to healthy control subjects. One patient with especially severe OCD did, however, exhibit impairment by misclassifying disgust expressions as anger expressions.
DISCUSSION
These data do not confirm the presence of disgust recognition deficits in individuals with OCD. In light of the deficits exhibited by one subject with severe OCD, disgust recognition deficits may be confined to an unidentified subset of people with OCD.
背景
基底神经节异常的患者在被要求识别展示不同情绪的个体照片中所描绘的情绪时，会将厌恶的面部表情误分类为愤怒的表情。施普伦格尔迈尔、杨、庞特等人（1997年）报告称，强迫症（OCD）患者——一种与基底神经节异常相关的焦虑症——也存在类似的厌恶识别缺陷。
方法
在本实验中，我们试图重复施普伦格尔迈尔、杨、庞特等人（1997年）的研究结果。
结果
我们未能重复施普伦格尔迈尔、杨、庞特等人关于强迫症患者相对于健康对照受试者存在厌恶识别缺陷的研究结果。然而，一名患有特别严重强迫症的患者确实表现出了缺陷，他将厌恶表情误分类为愤怒表情。
讨论
这些数据并未证实强迫症患者存在厌恶识别缺陷。鉴于一名患有严重强迫症的受试者所表现出的缺陷，厌恶识别缺陷可能仅限于未被识别的一部分强迫症患者。
