道路交通与生活场景诱发下驾驶人情绪的脑认知响应差异

为了探究道路交通场景和生活场景下驾驶人情绪脑认知响应差异,邀请10名被试分别在2种场景下完成情绪诱导实验。从离散情绪和连续情绪2个维度分析2种场景下前额与外额含氧血红蛋白和脱氧血红蛋白浓度的差异,进而推断脑区的激活程度。结果表明,道路交通场景相较于生活场景,愤怒与惊讶情绪下前额与外额的激活程度更强,快乐情绪下前额与外额的激活程度更低,恐惧情绪下仅在前额发现了显著差异,且激活程度更低;道路交通场景相较于生活场景,愤怒、恐惧、惊讶3种情绪前额与外额的脑功能连接强度更高,快乐与悲伤2种情绪下前额与外额的脑功能连接强度更低。

Difference in Brain Cognitive Responses to Driver Emotions Induced by Road Traffic and Daily Life Scenarios

To investigate potential differences in the brain cognitive responses to emotions between road traffic and daily life scenarios, ten participants were invited to complete emotion induction experiments in both road traffic and daily life settings. Then we analyzed the differences in concentrations of oxygenated and deoxygenated hemoglobin in the frontal and lateral lobes across two scenarios, discrete emotion and continuous emotion, in order to infer the activation degree of brain regions. The results show that the activation of the frontal and lateral lobes is stronger under anger and surprise emotions in road traffic scenario than that in daily life scenario, but lower in happiness emotion. However, significant differences are found only in the frontal lobe under fear emotion, and the activation is lower. In addition, compared with daily life scenario, the functional connectivity strength between the frontal and lateral lobes is higher under anger, fear, and surprise emotions in road traffic scenario, while it is lower under happiness and sadness emotions.
