心智技能对监控操作员情境意识的影响——心智游移的调节作用

Influence of mental skills on situational awareness of monitoring operators:moderating effect of mind wandering

为保持操作员良好的情境意识(SA),减少心智游移发生,降低操作失误,招募68名被试,开展采煤机状态监控实验,记录作业绩效、SAGAT问卷、心智技能问卷和心智游移问卷数据,以此探究心智技能对SA及其3阶段的影响,并检验心智游移的调节作用。研究结果表明:心智技能正向影响SA,随着心智技能水平升高,反应时更短,任务正确率和SAGAT问卷正确率更高;心智技能与SA 3阶段显著正相关,对感知和理解层面的影响更大;心智游移负向调节二者的正向关系,且分别在心智技能与SA 3阶段之间起负向调节作用,其在预测层面的削弱作用最显著。研究结果可为保障工作面顺利生产和提高智能矿山安全程度提供管理建议。

To maintain the good situational awareness(SA)of operators,and reduce the occurrence of mind wandering and operation error,68 subjects were recruited to carry out the experiment of shearer state monitoring,then the data of job performance,SAGAT scale,mental skill questionnaire and mind wandering questionnaire were recorded to explore the influence of mental skills on SA and its three stages,and the moderating effect of mind wandering was verified.The results show that the mental skills have positive effect on SA.With the improvement of mental skills level,the operators have shorter reaction time and higher accuracy and SAGAT scale scores.There is a significant positive correlation between mental skills and the three stages of SA,and the impact on perception and understanding level is greater.In addition,the mind wandering negatively regulates the positive relationship between mental skills and SA,and negatively moderates the relationship between mental skills and the three stages of SA respectively,while the weakening effect is the most significant at the prediction level.The research results can provide management suggestions for ensuring the smooth production of working face and improving the safety level of smart mine.
