Yang等人（1）认为性别和年龄是我们研究中的混杂因素（2）。然而，根据定义，它们实际上不是。他们的性别差异论点对我们从日本年轻男性样本中得出的结果没有任何影响。在我们的文章中，我们感兴趣的是在最后通牒博弈中观察到的不公平反应的个体差异。我们充分意识到，性别和年龄是许多大脑功能及其障碍的主要因素（3，4）。我们还了解到，性格的性别差异是一个主要的研究课题。因此，我们将重点放在年轻男性志愿者身上。此外，为了防止年轻女性受到不必要的辐射，我们首先只招募男性志愿者。性别差异已经作为一种限制因素得到了解决。如果在女性样本中也能观察到类似的结果，那么我们强烈建议对此进行测试。至于中介分析，我们也测试了自举方法。我们从我们的数据中生成了1,000个样本，并使用自助偏差校正和加速自助95%置信区间（CI）（5）测试了间接效应的显著性。如果CI为
Yang et al (1) argue that sex and age are confounding factors in our study (2). However, by definition, they actually are not. Their sex difference argument does not have any influence on our result from a young Japanese male sample. In our article, we were interested in individual differences in reaction to unfairness observed in the ultimatum game. We were fully aware that sex and age are major factors to account for many brain functions and their disorders (3, 4). We also understand that sex difference in personalities is a major research topic. Therefore, we focused on young male volunteers. In addition, to prevent young females from unnecessary radiation exposure, we recruited only male volunteers as a first step. Sex difference was already addressed as a limitation. Needless to say, it is highly recommended to test this if a similar result could be observed in a female sample as well.As for mediation analysis, we have also tested a bootstrapping method. We generated 1,000 samples from our data and tested the significance of the indirect effect using the bootstrap biascorrected and accelerated bootstrap 95% confidence intervals (CI)(5). The indirect effect was considered significant if CI of
