众所周知，他人的注视是社交焦虑的一个特别常见的原因。在目前的研究中，我们测量了事件相关电位（ERP）在注视知觉的人或没有高社交焦虑倾向（HSA）。实验刺激是面部眼睛区域的灰度图像，显示直接或转移的眼睛凝视（凝视或凝视）或闭上的眼睛。我们发现，在右枕颞部位（N170）的负性ERPs和额中央区（P2）的正性ERPs被眼睛注视刺激所诱发。虽然N170不受社交焦虑倾向的影响，但HSA组的P2振幅显著大于低社交焦虑倾向（LSA）组。此外，P2潜伏期组和条件之间的显着的相互作用：HSA组表现出更短的P2潜伏期，在响应于直接凝视比转移凝视，而LSA组没有。这些结果表明，眼睛凝视的神经处理强烈影响社会焦虑倾向。特别是，直接凝视的注意处理在具有HSA倾向的个体中更为突出。
The gaze of others is known to be a particularly common cause of social anxiety. In the current study, we measured event-related potentials (ERPs) during gaze perception among people with or without high socially anxious tendencies (HSA). The experimental stimuli were grayscale images of the eye region of a face, showing direct or averted eye gaze (leftward gaze or rightward gaze) or closed eyes. We found that negative ERPs at a right occipito-temporal site (N170) and positive ERPs at the fronto-central region (P2) were evoked by eye gaze stimuli. While the N170 was not affected by socially anxious tendencies, the amplitude of the P2 was significantly greater in the HSA group than in the low socially anxious tendencies (LSA) group. Furthermore, P2 latency showed a significant interaction between groups and conditions: the HSA group exhibited shorter P2 latencies in response to direct gaze than averted gaze, while the LSA group did not. These results indicate that the neural processing of eye gaze is strongly influenced by socially anxious tendencies. In particular, the attentional processing of direct gaze is more prominent in individuals with HSA tendencies.
