We conducted studies with an ultimate aim of elucidating neural computations for social decision making. While we made several achievements towards the aim, here we summarize the result of a most central study. Using human fMRI experiment, combined with so-called model-based analysis, we investigated brain functions for value-based decision making, comparing two situations ; when the subject makes value-based decisions for their self reward and when the subjects predicts what value-based decision another person would make, when the other person is in the same situation for themselves. We found that the ventromedial frontal cortex plays a central role in simulating the other's value-based decision making process.

我们进行研究的最终目的是阐明社会决策的神经计算。虽然我们朝着这个目标取得了一些成就，但在这里我们总结了一项最核心的研究结果。利用人体功能磁共振成像实验，结合所谓的基于模型的分析，我们研究了基于价值的决策的大脑功能，比较了两种情况；当被试为了自己的利益做出基于价值的决定时当被试预测另一个人会做出基于价值的决定时，当另一个人也处于同样的情况下。我们发现，腹内侧额叶皮层在模拟他人基于价值的决策过程中起着核心作用。
