社交孤僻的人在广泛的环境中与陌生和熟悉的同伴一起表现出孤独的行为。这种退缩倾向可能是由过去或预期的负面社交遭遇造成的。此外，社交孤僻的人在基线和压力下经常表现出右额叶脑电图（EEG）不对称。在当前的研究中，我们检查了年轻人（N = 41）在基线时额叶脑电图活动的变化，因为他们观看了引发焦虑或良性的演讲视频，以及他们随后为自己的演讲做准备。结果表明，只有暴露于焦虑视频的社交孤僻参与者的右额叶脑电图活动相对于左额叶有所增加。这些结果表明，情境情感线索可能会引发个人对压力的反应，特别是如果它们说明或证实了预期的负面事件。 (C) 2011 Elsevier Inc. 保留所有权利。
Socially withdrawn individuals display solitary behavior across wide contexts with both unfamiliar and familiar peers. This tendency to withdraw may be driven by either past or anticipated negative social encounters. In addition, socially withdrawn individuals often exhibit right frontal electroencephalogram (EEG) asymmetry at baseline and when under stress. In the current study we examined shifts in frontal EEG activity in young adults (N = 41) at baseline, as they viewed either an anxiety-provoking or a benign speech video, and as they subsequently prepared for their own speech. Results indicated that right frontal EEG activity increased, relative to the left, only for socially withdrawn participants exposed to the anxious video. These results suggest that contextual affective cues may prime an individual's response to stress, particularly if they illustrate or substantiate an anticipated negative event.
