摘要
Crowd behavior in group incidents is often like herd behavior. Neuroscience is an emerging research field, which contributes to revealing the mechanisms of decision-making behavior. This study investigated the influence of emotion on decision-making in herd behavior and the cognitive characteristics in group incidents from a two-stage experiment. The behavior data demonstrated that herd behavior really existed in group incidents, and interaction between emotion and participation rate influenced the decision making. When participation, rate was 0% or 25%, compared with the negative emotion, decision makers who felt positive emotion tended to choose not to participate in the herd behavior. When the rate rose to 75%, compared with the positive emotion, the decision-makers in negative emotion may be more inclined to herd behavior. The ERP analysis of the emotion presentation demonstrated, an increased early, negativity (NI) and attenuated early negativity (N2) elicited by an angry or sorrowful mood compared with positive emotion. The weakness of early negativity (N2) would make people experience less struggle while making decisions, and it also led to an increase in the amplitude of P3, which reduced the difficulty of decision making.
