神经影像学研究已经彻底调查了当我们把自己放在另一个人的鞋子里时被招募的大脑区域。与第一人称视角（1 PP）相反，采用第三人称视角（3 PP）与下顶叶皮层、内侧后皮层和前额叶皮层的大脑激活有关。在这里，我们第一次调查的神经网络，产生认知的观点采择的发展。12名成人（年龄25-32岁）和12名学龄儿童（年龄8-10岁）进行了调查，使用功能磁共振成像（fMRI）。行为上，我们发现随着年龄的增长，3 PP和1 PP之间的反应时间差异减少，表明成年人在处理3 PP时更有效。尽管反应时间不同，但两组人的判断同样准确。脑成像数据表明，在左下顶叶皮质和楔前叶的成人在3 PP与1 PP判断相比，神经活动。此外，儿童的背外侧前额叶皮层和右下周皮层的活动也有所增强。我们发现组与右背外侧前额叶皮层和右下顶叶皮层的大脑激活之间存在显著的相互作用。这些结果表明，推理他人思想的能力的发展伴随着活动从额叶到后部大脑区域以及从双侧到单侧左下顶叶皮层的转变。(C)2009 Elsevier Inc.

Neuroimaging studies have thoroughly investigated brain regions that are recruited when we put ourselves in another person's shoes. Taking a third-person perspective (3PP) as opposed to a first-person perspective (1PP) has been associated with brain activation in the inferior parietal cortex, the medial posterior cortex and the prefrontal cortex. Here we investigate for the first time the development of the neural network that yields cognitive perspective taking. Twelve adults (aged 25-32 years) and twelve school-aged children (aged 8-10 years) were investigated using functional magnetic resonance imaging (fMRI). Behaviorally, we found a decrease of reaction time differences between 3PP and 1PP with age indicating that adults were more efficient in processing a 3PP. Despite the reaction time differences both groups were equally accurate in their judgments. Brain imaging data indicated neural activity in the left inferior parietal cortex and precuneus for adults during 3PP as compared with 1PP judgments. Children additionally showed enhanced activity in the dorsolateral prefrontal cortex and the right inferior perietal cortex. We found a significant interaction between groups and brain activation in the right dorsolateral prefrontal cortex and in the right inferior parietal cortex. These results suggest that the development of the ability to reason about another person's mind accompanies a shift in activity from frontal to posterior brain regions and from bilateral to unilateral left inferior parietal cortex.
