In the present research we investigated whether the direction of the attentional bias in line bisection judgment displayed by healthy subjects is influenced by the evaluation of the social distance between self and other. We used inhibitory repetitive transcranial magnetic stimulation (rTMS) trains over the right and left parietal cortex to investigate the role of these regions in the task. Following right parietal rTMS, the self face is perceived as closer when it is located at the right line endpoint; following left parietal rTMS, the self face is perceived as closer when it is located at the left line endpoint. In both cases, the side of space ipsilateral to the rTMS is underestimated from an attentional point of view, while it is overestimated from a social point of view. These results are a projection of how an individual perceives himself in the social relational space.
在本研究中，我们调查了健康受试者在直线二分判断中表现出的注意偏向方向是否受到自我与他人之间社会距离评估的影响。我们使用抑制性重复经颅磁刺激（rTMS）对右顶叶和左顶叶进行刺激，以研究这些区域在任务中的作用。右顶叶 rTMS 刺激后，当自我面孔位于右侧线终点时，自我面孔会被感知为更近；左顶叶 rTMS 刺激后，当自我面孔位于左侧线终点时，自我面孔会被感知为更近。在这两种情况下，从注意的角度来看，rTMS 同侧的空间被低估，而从社会角度来看，它被高估。这些结果反映了个体如何在社会关系空间中感知自己。
