In order to reduce the occurrence of safety accidents in coal mine production,from the perspective of emotion control,based on Valence-Arousal(V-A)emotional model,combined with emotional arousal methods and physiological measurement techniques,a cognitive experiment of miners'safety behavioral competence was conducted.Attention and decision-making time under different emotional states were measured.The regression analysis was used to investigate the continuous effects of degree-of-arousal on attention and risk preference under different emotional valence.The results show that in low degree-of-arousal and positive emotions,decreasing degree-of-arousal leads to weaker attention and more risk aversion in decision making in miners.In the high degree-of-arousal and positive emotions,with the increase of degree-of-arousal,the level of attention and risk aversion of miners in decision-making first increases and then decreases,until it is lower than neutral emotions.In low degree-of-arousal and negative emotions,decreasing degree-of-arousal would make miners pay less attention and have lower risk aversion in decision-making.In the high degree-of-arousal and negative emotions,an increase in degree-of-arousal increases and then decreases the attention and risk aversion in decision making,even until they are lower than the level of neutral emotions.By contrast,in the high degree-of-arousal range,increasing degree-of-arousal in positive emotion is more likely to reduce miners'safety behavioral competence to lower than the level of neutral emotional.
