灾害的突然发生往往会使人们情绪激动，使他们难以进行有计划的疏散活动。然而，尚未对自然灾害情况下的生物反应进行调查。本研究旨在：1）发现地震视频观看和中性视频观看条件下的情绪反应的差异; 2）调查观看地震视频时的情绪反应与主观情绪评估/个体焦虑特质的关系。健康的年轻人（n= 12）观看地震和中性视频，我们测量生物信号并进行情绪评估。我们使用可穿戴的双通道近红外光谱（NIRS）装置测量生物信号，如脉搏率和背外侧前额叶皮层的脑血流量。根据近红外光谱数据计算自主神经指数（交感神经和副交感神经指数）。主观情绪评估是使用自我评估模型。同时进行状态-特质焦虑问卷调查。我们发现，在观看地震录像的条件下，交感神经活动显着低于中性的。生物学指标可以推断观看地震录像时的主观情绪评价和个体的焦虑特质。基于双通道NIRS数据的自主神经指数可能能够估计对不同刺激的情绪反应。
Sudden occurrences of disasters often agitate people emotionally and make their planned evacuation activities difficult. However, the biological responses to natural disaster situations have not been investigated. This study aimed to: 1) discover the difference in emotional responses between earthquake video-watching and neutral video-watching conditions, and 2) investigate the relationship between emotional responses during watching an earthquake video and subjective emotion assessment/individual anxiety traits. Healthy young adults (n= 12) watched earthquake and neutral videos, and we measured biological signals and performed emotional assessment. We measured biological signals, such as pulse rate and cerebral blood flow in the dorsolateral prefrontal cortex, using a wearable two-channel near-infrared spectroscopy (NIRS) unit. Autonomic nerve indexes (sympathetic and parasympathetic indexes) were calculated from the NIRS data. Subjective emotion assessment was made using the Self-Assessment Manikin. The State-Trait Anxiety Inventory Questionnaire was also performed. We found that sympathetic nerve activity was significantly lower in the earthquake video-watching condition than during the neutral one. Biological indicators inferred both subjective emotion assessment during watching the earthquake video and individual anxiety traits. Autonomic indices based on 2-channel NIRS data may be able to estimate emotional responses to different stimuli.
