Situational awareness is recognised as an important factor in the performance of individuals and teams in dynamic decision-making (DDM) environments (Salmon et al. 2014 ). The present study was designed to investigate whether the scores on the WOMBAT™ Situational Awareness and Stress Tolerance Test (Roscoe and North 1980 ) would predict the transfer of DDM performance from training under different levels of cognitive load to a novel situation. Participants practised a simulated firefighting task under either low or high conditions of cognitive load and then performed a (transfer) test in an alternative firefighting environment under an intermediate level of cognitive load. WOMBAT™ test scores were a better predictor of DDM performance than scores on the Raven Matrices. Participants with high WOMBAT™ scores performed better regardless of their training condition. Participants with recent gaming experience who practised under low cognitive load showed better practice phase performance but worse transfer performance than those who practised under high cognitive load.
The relationship between task experience, situational awareness ability, cognitive load and the transfer of dynamic decision-making (DDM) performance was investigated. Results showed that the WOMBAT™ test predicted transfer of DDM performance regardless of task cognitive load. The effects of cognitive load on performance varied according to previous task-relevant experience.
态势感知被认为是动态决策(DDM)环境中个人和团队表现的一个重要因素(萨尔蒙等人,2014年)。本研究旨在调查WOMBAT™态势感知与压力耐受测试(罗斯科和诺思,1980年)的得分是否能预测在不同认知负荷水平下训练的DDM表现向新情境的迁移。参与者在低或高认知负荷条件下练习模拟灭火任务,然后在中等认知负荷水平的另一个灭火环境中进行(迁移)测试。WOMBAT™测试得分比瑞文推理测验得分更能预测DDM表现。无论训练条件如何,WOMBAT™得分高的参与者表现更好。有近期游戏经验且在低认知负荷下练习的参与者在练习阶段表现更好,但在迁移表现上比在高认知负荷下练习的参与者更差。
研究了任务经验、态势感知能力、认知负荷与动态决策(DDM)表现迁移之间的关系。结果表明,无论任务认知负荷如何,WOMBAT™测试都能预测DDM表现的迁移。认知负荷对表现的影响因先前与任务相关的经验而异。
