Patients with body dysmorphic disorder (BDD) have difficulty in recognising facial emotions, and there is evidence to suggest that there is a specific deficit in identifying negative facial emotions, such as sadness and anger.
This study investigated facial emotion recognition in 19 individuals with BDD compared with 21 healthy control participants who completed a facial emotion recognition task, in which they were asked to identify emotional expressions portrayed in neutral, happy, sad, fearful, or angry faces.
Compared to the healthy control participants, the BDD patients were generally less accurate in identifying all facial emotions but showed specific deficits for negative emotions. The BDD group made significantly more errors when identifying neutral, angry, and sad faces than healthy controls; and were significantly slower at identifying neutral, angry, and happy faces.
These findings add to previous face-processing literature in BDD, suggesting deficits in identifying negative facial emotions. There are treatment implications as future interventions would do well to target such deficits.
躯体型变形障碍(BDD)患者对面部情绪的识别存在困难,有证据表明,他们在识别悲伤和愤怒等负面面部情绪时存在特定的缺陷。
本研究调查了 19 名 BDD 患者和 21 名健康对照者的面部情绪识别能力,他们完成了一项面部情绪识别任务,要求他们识别中性、快乐、悲伤、恐惧或愤怒表情所表现出的情绪。
与健康对照组相比,BDD 患者在识别所有面部表情时通常准确性较低,但对负面情绪表现出特定的缺陷。BDD 组在识别中性、愤怒和悲伤面孔时的错误明显多于健康对照组;在识别中性、愤怒和快乐面孔时的速度也明显较慢。
这些发现增加了 BDD 之前的面部处理文献,表明在识别负面面部情绪方面存在缺陷。这有治疗意义,因为未来的干预措施将很好地针对这些缺陷。
