Abstract:

In order to deeply analyze the mechanism of the effect of emotion on unsafe behavior, the correction method of unsafe behaviors were explored from the perspective of emotional control. Starting from the information cognition process, combining the eye-tracking technology and emotional arousal method, we designed an experiment on the influence of emotion on construction workers' unsafe behaviors based on the individual information cognition model. Using eye-tracking hotspot diagram and ANOVA(Analysis of Variance), the specific influence of emotion on construction workers' unsafe behaviors during the information cognition processing was explored by measuring the attention allocation, hazard recognition and risk propensity of workers in different emotional states. The results of the study show that: in the information acquisition stage of the cognitive process, positive emotions could promote workers' perception activities of on-site hazards, while in the information analysis stage, workers with positive emotions are more likely to have unsafe behaviors than those with negative emotions. Based on the emotional unsafe behavior model of individual information cognition, construction workers in positive emotional states are more inclined to intentional unsafe behaviors, while those in negative emotional states construction workers in positive emotional states are more inclined to unintentional unsafe behavior. It is suggested that construction enterprises should adopt targeted unsafe behavior control measures according to the emotional state of workers to improve the efficiency of on-site safety management.
