Research output: Chapter in Book/Report/Conference proceedingChapter


This chapter deals with two features of dynamic, interactive environments that make a standard application of the lens model problematic. The research presented here is one of the many efforts initiated and supported under the Tactical Decision Making Under Stress (TADMUS) program. A laboratory simulation modeled on the naval Combat Information Center (CIC) environment and the task of the Anti-Air Warfare Coordinator (AAWC) is observed in this fieldwork. Applying the lens model to the laboratory simulation in the context of the CIC and the AAWC was complicated by the dynamic nature of the task and environment. The lens model analysis indicated that the differences between high and low performers could be explained in part by the consistency with which participants executed their judgment strategies and in part by task knowledge.
