在本研究中，我们考察了健康被试在线等分判断中的注意偏向是否受自我与他人之间的社会距离评价的影响。我们在右侧和左侧顶叶皮质上使用抑制性重复经颅磁刺激(RTMS)训练，以研究这些区域在任务中的作用。在右顶叶rTMS之后，当自体位于右线终点时，它被感知为更近；在左顶端rTMS之后，当自体位于左线端点时，自体被感知为更近。在这两种情况下，从注意的角度来看，与rTMS同侧的空间被低估了，而从社会的角度来看，它被高估了。这些结果是个人如何在社会关系空间中感知自己的投射。
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.
