Abstract: 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.

Key words: inducing noise, construction worker, risk-taking behavior, causation mechanism, event-related potential (ERP), cranial nerve experiment
