Decades of research have established a link between emotional disorders and attentional biases for emotional stimuli, but the relationship between symptom severity and visual attention is still not fully understood. Depression has been associated with increased attention towards dysphoric stimuli and decreased attention on positive stimuli ("negativity bias"), and some studies have also shown this trend in anxiety disorders. We examined eye fixation variables in 47 participants with emotional disorders completing an emotion recognition task. Results showed that depression severity was not associated with increased fixations on dysphoric stimuli, however, higher levels of generalized anxiety predicted increased fixations in the mouth region of sad and happy faces. Higher levels of social interaction anxiety predicted reduced fixations in the eye region of happy faces. While we did not replicate the negativity bias that has been shown in prior studies, our sample was highly comorbid, indicating the need to consider comorbidity, disorder severity, and the task itself when conducting research on visual attention in clinical samples. Additionally, more attention should be paid to the mouth region of emotional faces, as it may provide more specific information regarding the visual processing of emotions.
数十年的研究已经确立了情绪障碍与对情绪刺激的注意力偏向之间的联系,但症状严重程度与视觉注意力之间的关系仍未完全阐明。抑郁症与对不愉快刺激的注意力增加和对积极刺激的注意力减少(“负性偏向”)有关,一些研究也表明焦虑症中存在这种趋势。我们在 47 名完成情绪识别任务的情绪障碍患者中检查了眼动变量。结果表明,抑郁严重程度与对不愉快刺激的注视增加无关,然而,广泛性焦虑水平越高,预示着对悲伤和快乐面孔的嘴部区域的注视增加。社交互动焦虑水平越高,预示着对快乐面孔的眼部区域的注视减少。虽然我们没有复制先前研究中显示的负性偏向,但我们的样本高度共病,这表明在对临床样本的视觉注意力进行研究时,需要考虑共病、疾病严重程度和任务本身。此外,应该更多地关注情绪面孔的嘴部区域,因为它可能提供有关情绪视觉处理的更具体信息。
