情境意识的理论模型、测量及其应用

情境意识（situation awareness简称SA）是个体对不断变化的外部环境的内部表征。在复杂、动态变化的信息环境中，它是影响操作者决策和绩效的关键因素。文章着重回顾并分析了情境意识的四种研究取向，主要的测量技术，及其在系统设计和评价、人员选拔和训练方面的应用，最后提出了未来需要深入研究的几个问题。

Situation Awareness:Approaches,Measures and Applications

Situation awareness (SA) is a constantly evolving picture of the state of the ongoing environment. In complex and dynamic environments, it is the key factor for operatiors decision making and performance. The article mainly reviewed and analyzed the four approaches used to define and explain SA, the four major SA measurement techniques, and applications of SA in system design and evaluation, personel selection, and training. Finally the author proposed some aspects that need to further research.
