The major aims of this study were to examine how, if at all, having higher levels of PTSD would be associated with performance on a facial affect recognition task in which facial expressions of emotion are superimposed on emotionally valenced, non-face images. College students with trauma histories (N = 90) completed a facial affect recognition task as well as measures of exposure to traumatic events, and PTSD symptoms. When the face and context matched, participants with higher levels of PTSD were significantly more accurate. When the face and context were mismatched, participants with lower levels of PTSD were more accurate than were those with higher levels of PTSD. These findings suggest that PTSD is associated with how people process affective information. Furthermore, these results suggest that the enhanced attention of people with higher levels of PTSD to affective information can be either beneficial or detrimental to their ability to accurately identify facial expressions of emotion. Limitations, future directions and clinical implications are discussed.
这项研究的主要目的是探讨,如果有的话,较高水平的 PTSD 是否与在一个面部表情识别任务中的表现相关,在这个任务中,情绪相关的非面部图像上会叠加面部表情。有创伤史的大学生(N=90)完成了面部表情识别任务以及暴露于创伤性事件和 PTSD 症状的测量。当面部和背景匹配时,PTSD 水平较高的参与者的准确性显著更高。当面部和背景不匹配时,PTSD 水平较低的参与者比 PTSD 水平较高的参与者更准确。这些发现表明,PTSD 与人们处理情感信息的方式有关。此外,这些结果表明,PTSD 水平较高的人对情感信息的增强注意力对他们准确识别面部表情的能力既有好处也有坏处。讨论了局限性、未来方向和临床意义。
