Abstract
Unsafe decision-making in coal mining can endanger not only the individual making the decision but also their colleagues and the overall safety of the mine. While prior studies have mainly examined decisions in self-involved safety risk scenarios, the impact of non-self-involved scenarios, where the risk affects others, remains underexplored.This study combines questionnaire surveys with an event-related potential (ERP) experiment to investigate how miners with varying levels of unsafe psychology make decisions in self-involved and non-self-involved safety risk scenarios.Behavioral findings indicate that both low and high unsafe psychology groups are more prone to unsafe decisions in non-self-involved scenarios, suggesting that self-involvement significantly influences decision-making. ERP results revealed that safety risk tasks elicited significant P300 and LPC components, with greater amplitudes observed in self-involved scenarios, reflecting higher attentional engagement. Furthermore, miners with low unsafe psychology showed larger P300 amplitudes and shorter latencies in self-involved scenarios, likely due to deeper cognitive processing and similar cognitive load. In non-self-involved scenarios, latency differences between groups were not significant, possibly due to stronger negative emotional responses among low unsafe psychology individuals.This study underscores the role of self-involvement in safety risk decision-making and provides new neurophysiological evidence (P300, LPC) to better understand the cognitive and emotional processes influencing mining safety behavior.
