Recently, conventional main control rooms are being gradually replaced by digital main control rooms in nuclear power plants, which results in changes of factors that have effects on diagnosis task performance. The experiment was conducted under four interfaces with different information acquisition methods (Query, Filter, Query-Filter combined, and Visual Search) to explore the influence of cognitive style on diagnosis task performance and possible interaction effects with information acquisition methods. Cognitive style was measured by Index of Learning Styles Questionnaire from four dimensions (Reflective/Active, Intuitive/Sensing, Verbal/Visual, and Global/Sequential). The results showed that cognitive style significantly affected diagnosis task performance, and had interaction effects with information acquisition method. Reflective/Active dimension had significant effect on diagnosis performance under Filter and Query-Filter combined interfaces (active participants performed better). Intuitive/Sensing dimension had significant effect on diagnosis performance under Query and Filter interfaces (intuitive participants performed better). Verbal/Visual dimension had significant effect on diagnosis performance under conventional Visual Search interface (visual participants performed better) and Query interface (verbal participants performed better). The results could be useful for human-machine interface design and the selection of operators in complex industrial systems.

近来，核电厂中的数字主控制室逐渐取代了常规主控制室，这导致影响诊断任务性能的因素发生了变化。该实验是在具有不同信息获取方法（查询，过滤器，组合查询和过滤器以及可视搜索）的四个界面下进行的，以探讨认知方式对诊断任务性能的影响以及与信息获取方法可能的交互作用。认知风格是通过学习风格指数调查表从四个维度（反射/主动，直觉/感官，言语/视觉和整体/顺序）进行衡量的。结果表明，认知方式显着影响诊断任务的执行，并与信息获取方法产生交互作用。在Filter和Query-Filter组合界面下，反射/主动维度对诊断性能有重大影响（主动参与者的表现更好）。直观/感知维度对“查询”和“过滤器”界面下的诊断性能有显着影响（直观的参与者表现更好）。在传统的视觉搜索界面（视觉参与者的表现更好）和查询界面（言语参与者的表现更好）下，言语/视觉维度对诊断性能具有显着影响。该结果对于人机界面设计以及复杂工业系统中操作员的选择很有用。直观/感知维度对“查询”和“过滤器”界面下的诊断性能有显着影响（直观的参与者表现更好）。在传统的视觉搜索界面（视觉参与者的表现更好）和查询界面（语言参与者的表现更好）下，言语/视觉维度对诊断性能具有显着影响。该结果对于人机界面设计以及复杂工业系统中操作员的选择很有用。直观/敏感维度对“查询”和“过滤器”界面下的诊断性能有显着影响（直观的参与者表现更好）。在传统的视觉搜索界面（视觉参与者的表现更好）和查询界面（语言参与者的表现更好）下，言语/视觉维度对诊断性能具有显着影响。该结果对于人机界面设计以及复杂工业系统中操作员的选择很有用。
