Direct-gaze signals are known to modulate human cognition, including self-awareness. In the present study, we specifically focused on 'bodily' self-awareness and examined whether direct gaze would modulate one's interoceptive accuracy (IAcc)-the ability to accurately monitor internal bodily sensations. While viewing a photograph of a frontal face with a direct gaze, an averted face or a mere white cross as a baseline, participants were required to count their heartbeats without taking their pulse. The results showed higher IAcc in the direct-gaze condition than in the averted-face or baseline condition. This was particularly the case in participants with low IAcc at baseline, indicating that direct gaze enhanced the participants' IAcc. Importantly, their heart rate was not different while viewing the direct gaze and averted face, suggesting that sensitivity to interoceptive signals, rather than physiological arousal, is heightened by direct gaze. These findings demonstrate the role of social signals in our bodily interoceptive processing and support the notion of the social nature of self-awareness.

直接注视可以提高感知的准确性。

已知直接注视信号可调节人的认知,包括自我意识。在本研究中,我们特别关注“身体”自我意识,并研究了直接注视是否会调节人的感知准确性(IAcc),即准确监测内部身体感觉的能力。在以直视,张开的脸或仅以白色十字作为基准查看正面的照片时,要求参与者计数心跳而不用脉动。结果表明,在直接注视条件下,IAcc高于在转脸或基线条件下的IAcc。在基线时IAcc较低的参与者中尤其如此,这表明直接注视会增强参与者的IAcc。重要的是,他们在观察直接注视和避免面部表情时的心率没有变化,提示直接注视会提高对感受性信号的敏感性,而不是生理唤醒的敏感性。这些发现证明了社会信号在我们的身体感受过程中的作用,并支持自我意识的社会性质的概念。
