Previous research has found that individuals with social phobia differ from controls in their processing of emotional faces. For instance, people with social phobia show increased attention to briefly presented threatening faces. However, when exposure times are increased, the direction of this attentional bias is more unclear. Studies investigating eye movements have found both increased as well as decreased attention to threatening faces in socially anxious participants. The current study investigated eye movements to emotional faces in eight patients with social phobia and 34 controls. Three different tasks with different exposure durations were used, which allowed for an investigation of the time course of attention. At the early time interval, patients showed a complex pattern of both vigilance and avoidance of threatening faces. At the longest time interval, patients avoided the eyes of sad, disgust, and neutral faces more than controls, whereas there were no group differences for angry faces.
先前的研究发现,社交恐惧症患者在处理情绪面孔方面与对照组存在差异。例如,社交恐惧症患者对短暂呈现的威胁性面孔表现出更多关注。然而,当暴露时间增加时,这种注意力偏差的方向就更加不明确了。研究眼动的研究发现,社交焦虑参与者对威胁性面孔的注意力既有增加也有减少。本研究调查了8名社交恐惧症患者和34名对照组对情绪面孔的眼动情况。使用了三种不同暴露持续时间的不同任务,这使得能够研究注意力的时间进程。在早期时间间隔,患者对威胁性面孔表现出警惕和回避的复杂模式。在最长时间间隔,患者比对照组更多地回避悲伤、厌恶和中性面孔的眼睛,而在愤怒面孔上则没有组间差异。
