摘　　要：为揭示施工噪声诱发冒险行为的机制,提高安全绩效,基于最大适应性理论和风险情感理论,构建施工噪声诱发建筑工人冒险行为的心理机制模型,采用事件相关电位(ERP)技术开展脑神经试验,研究不同声音条件下建筑工人的行为变化和心理特性。结果表明:噪声能影响信息感知、加工过程,与安静环境相比,高水平施工噪声诱发P2、P3、晚正电位(LPP)成分更大的波幅,促进自我损耗和奖赏寻求倾向,从而导致行为决策的反应时间延长、冒险行为增加。In order to reveal mechanism of risk-taking behavior induced by construction noise so as to improve safety performance,a psychological mechanism model of it was established based on maximum adaptability and risk-as-feelings theories.Then,brain nerve experiments were conducted by utilizing ERP technique,and behavioral changes and psychological characteristics of construction workers under different sound conditions were studied.The results show that noise can affect information perception and processing.Compared with cases of quiet environment,high level construction noise induces greater amplitude of P2,P3 and LPP components,which promotes self-depletion and reward-seeking tendency,resulting in longer response time for behavioral decision-making and an increase of risk-taking behavior.
