Abstract：
A questionnaire survey and an event-related potential (ERP) experiment were used to reveal the impact of safety attitudes on risk perception. The results revealed that during hazard identification, the N130 amplitude of subjects with negative safety attitude was significantly higher, which implied that subjects with negative safety attitude were more likely to feel confused. During risk analysis, subjects with positive safety attitude were more inclined to overestimate the probability and damage degree of risks; subjects with positive safety attitudes displayed higher P150 and late positive potential amplitudes, which indicated that subjects with positive safety attitudes devoted more attention to risks in the early stage of risk analysis and had a more intense affective response in the later period. The risk judgment ability of subjects with positive safety attitude was affected by time pressure, and they exhibited higher risk judgment accuracy only under no time pressure.
摘要：
使用问卷调查和事件相关电位（ERP）实验来揭示安全态度对风险感知的影响。结果表明，在危害识别过程中，消极安全态度受试者的N130波幅明显较高,这意味着具有消极安全态度的受试者更容易感到困惑。在风险分析期间，具有积极安全态度的受试者更倾向于高估风险的概率和损害程度；具有积极安全态度的受试者表现出更高的P150和晚期正电位振幅，这表明，具有积极安全态度的受试者在风险分析的早期阶段更加关注风险，而在后期有更强烈的情感反应。具有积极安全态度的受试者的风险判断能力受到时间压力的影响,只有在没有时间压力的情况下，他们才表现出更高的风险判断准确性。
