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

Abstract:

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.
