认知负荷对胶轮车司机不安全行为的眼动研究
Eye movement study of cognitive load on the rubber wheel drivers' unsafe behavior
摘要
Abstract
In order to explore the influence of cognitive load on the unsafe behavior of rubber wheel drivers in coal mines,we designed eye movement experiments based on cognitive load from the physio-logical characteristics and psychological needs of unsafe behavior of rubber wheel drivers.The study collected subjective scale scores and unsafe behavior characteristic indicators such as pupil diameter,fixation times,gaze duration,electrocardiogram signal,and response time and accuracy rate to tasks in low,medium,and high cognitive load states.SPSS 26.0 was used to analyze the significance,mean,and standard deviation of each indicator.The research results show that:As the difficulty of the experiment increases,the NASA-TLX score of rubber wheel drivers significantly increases,indicating that the N-back paradigm of the experiment effectively induces varying degrees of cognitive load in the subjects;As the cognitive load increases,the reaction time,pupil diameter,gaze duration of rubber wheel drivers increase significantly,the accuracy rate and the number of gaze decreases significantly,and the cogni-tive load is significantly correlated with physiological parameters such as the heart rate and the variabil-ity of the heart rate,which indicates that the level of unsafe behaviors of rubber wheel drivers increases gradually with the increase of the cognitive load.Namely,cognitive load affects the unsafe behavior of rubber wheeler drivers.The results of the study may provide a basis for coal mines to alleviate the cog-nitive load of rubber truck drivers and reduce the generation of unsafe behaviors.关键词
