Demonstrating the Effect of Context on the Information Processing of Patriot Air Defense Officers

Leonard Adelman Dept. of Operations Research & Engineering and C3I Center of Excellence George Mason University

The talk describes research with Patriot air defense teams conducted using the Patriot simulation facility at Ft. Bliss, TX. The research supports the following hypotheses: (1) situation-specific, contextual features of a task can cause experienced personnel, both individually and in two-person teams, to reinterpret the meaning of the same information when it is presented in two different ordered sequences; (2) the result is that the same information can lead to different conclusions; and (3) the type of order effect will be primacy or recency depending on whether the most recent information can be explained away or not, respectively. More generally, the results demonstrate the importance of situation-specific, contextual features in understanding judgment processes.
