人与人之间的比较在社会判断和人类决策中普遍存在，但其神经基础研究甚少。当参与者比较名人的心理（智力）和身体（身高）特征时，我们测量了大脑活动，发现内侧额叶，眶额和边缘区以及颞顶交界处的激活。这个网络在很大程度上是由心理比较驱动的，在内侧前额叶皮层的几个区域中，智力活动高于身高比较，这表明它们的激活与人的比较需求有关。人的比较网络与经典心理理论任务中通常描述的网络惊人地重叠。我们将这种重叠解释为索引使用的角度采取共同的人的比较和心理理论。(C)2007年爱思唯尔公司All rights reserved.
Person comparison is pervasive in social judgment and human decision making and yet its neural substrate is poorly explored. We measured brain activity when participants compared psychological (intelligence) and physical (height) characteristics of famous people and found activation of medial frontal, orbitofrontal and limbic areas and the temporoparietal junction. This network was largely driven by the psychological comparison, with activity being higher for intelligence than height comparison in several areas in medial prefrontal cortex, suggesting that their activation scales with the demand on person comparison. The person comparison network overlaps strikingly with that commonly described for classic theory of mind tasks. We interpret this overlap as indexing the use of perspective taking common to person comparison and theory of mind. (C) 2007 Elsevier Inc. All rights reserved.
