Abstract

In order to improve safety management in construction and effectively reduce unsafe behavior of construction workers, seven types of individual factors and four types of environmental factors affecting cognitive process failure of their unsafe behaviors were sorted out. Then, a four-stage causation model of failure was established, and Matlab was used to simulate process of cognitive failure caused by multiple factors. The results show that environmental factors affect workers ' cognitive processes by influencing individual factors. Inadequate safety awareness and safety knowledge will lead to cognitive failure in first stage while underestimating risk is a main reason for it in second stage. Failure to choose a safe motivation and lower risk acceptance will lead to cognitive failure in third stage, and failure to perform actions properly leads to that in fourth stage. Moreover, good subjective norms help to correct cognitive bias in second stage of workers' cognitive process. © 2020 China Safety Science Journal
