<p>Information about emergencies affects decision-making and cognitive processing.

In this study, we used normal negative events as a reference to investigate the impact of emergencies on risky decision-making preferences. In addition, we used deviant stimuli to induce visual mismatched negative (vMMN) to investigate the effect of emergencies on the brain’s automatic processing.

摘要

Information about emergencies affects decision-making and cognitive processing. However, the majority of existing research has been based on the assumption that critical incidents lead to negative emotions such as fear and anxiety. We argue that this argument fails to consider the distinctive nature of emergencies. In this study, we used normal negative events as a reference to investigate the impact of emergencies on risky decision-making preferences. In addition, we used deviant stimuli to induce visual mismatched negative (vMMN) to investigate the effect of emergencies on the brain’s automatic processing. The results showed that participants in the emergency induction performed more conservatively in several decision-making tasks and the amplitude of P2 was significantly larger. Participants produced vMMN in the emergency condition but not in the normal negative condition. This study demonstrates that emergencies lead to more conservative decision-making preferences and stronger P2 responses, without affecting automatic processing capacity during the initial stages of attention. These findings provide valuable insights into understanding the impact of emergency events on individuals.
