功能性近红外光谱(FNIRS)是研究道德情绪神经基础的一种很有前途的脑成像手段。然而，使用fNIRS测量道德情绪的可行性还没有建立起来。在本研究中，我们使用fNIRS来检测两种典型的道德情绪--内疚和羞耻--所引起的大脑激活。我们向参与者呈现内疚和羞愧的情境，以唤起情绪反应，并使用fNIRS测量大脑活动。单变量一般线性模型分析显示，在眶前叶皮质、背外侧前额叶皮质和中回，两种情绪都被显著激活，而在右侧颞顶交界处，负罪感被特异性激活。多元分类分析表明，总体识别正确率为52.50%，显著高于对内疚、羞耻和中性情绪的识别正确率。这些结果表明，用fNIRS来评估内疚和羞耻引起的大脑激活是可行的，并显示了fNIRS在研究道德情绪的神经关联方面的潜力。
Functional near-infrared spectroscopy (fNIRS) is a promising brain imaging modality for studying the neural substrates of moral emotions. However, the feasibility of using fNIRS to measure moral emotions has not been established. In the present study, we used fNIRS to detect the brain activation evoked by two typical moral emotions-guilt and shame. We presented the participants with guilt and shame context to evoke emotional responses and measured the brain activity by using fNIRS. The univariate general linear model analysis showed significant activations for both emotions in the orbitofrontal cortex, dorsolateral prefrontal cortex, and middle temporal gyrus, and specific activation for guilt in the right temporoparietal junction. The multivariate classification analysis showed an overall recognition accuracy of 52.50%, which was significantly higher than the chance level in classifying the guilt, shame, and neutral emotions. These results suggested the feasibility of using fNIRS to assess the brain activation evoked by guilt and shame and demonstrated the potentials of fNIRS in studying the neural correlates of moral emotions.
