先前关于空间透视的神经影像学研究往往不会激活大脑的心理网络。我们预测，需要在交流环境中使用观点采择的任务将导致心智化区域的激活。在当前任务中，参与者按照听觉指令移动一组架子中的物体。采用 2 x 2 因子设计。在导演因素中，两名导演（一名女性和一名男性）要么站在货架后面或旁边，要么被象征性线索所取代。在物体因素中，参与者需要利用提示（导演的位置或象征性提示）从三个可能的物体中选择一个，或者只能选择一个物体。仅仅董事的存在就与上背侧内侧前额叶皮层（MPFC）和上/中颞沟的活动相关，延伸到纹外体区域和后上颞沟（pSTS），先前发现这些区域分别对人体和面部做出反应。导演和客体因素之间的相互作用，要求参与者考虑导演的视角，导致额外招募上背侧 MPFC（在思考不同他人的心理状态时激活的区域）和颞中回，延伸到左颞极。我们的研究结果表明，在交流环境中使用观点采择，要求参与者不仅要思考对方所看到的内容，还要思考他/她的意图，这会导致上背侧 MPFC 和部分社交大脑网络的募集。 (c) 2010 Elsevier Inc. 保留所有权利。
Previous neuroimaging studies of spatial perspective taking have tended not to activate the brain's mentalising network. We predicted that a task that requires the use of perspective taking in a communicative context would lead to the activation of mentalising regions. In the current task, participants followed auditory instructions to move objects in a set of shelves. A 2 x 2 factorial design was employed. In the Director factor, two directors (one female and one male) either stood behind or next to the shelves, or were replaced by symbolic cues. In the Object factor, participants needed to use the cues (position of the directors or symbolic cues) to select one of three possible objects, or only one object could be selected. Mere presence of the Directors was associated with activity in the superior dorsal medial prefrontal cortex (MPFC) and the superior/middle temporal sulci, extending into the extrastriate body area and the posterior superior temporal sulcus (pSTS), regions previously found to be responsive to human bodies and faces respectively. The interaction between the Director and Object factors, which requires participants to take into account the perspective of the director, led to additional recruitment of the superior dorsal MPFC, a region activated when thinking about dissimilar others' mental states, and the middle temporal gyri, extending into the left temporal pole. Our results show that using perspective taking in a communicative context, which requires participants to think not only about what the other person sees but also about his/her intentions, leads to the recruitment of superior dorsal MPFC and parts of the social brain network.
