Objective: The purpose of the current research was to investigate whether performance in nonradar training would predict performance in radar training.
Background: There is a discussion in the Federal Aviation Administration about the necessity of keeping nonradar training as part of the required selection criteria for radar controllers. In nonradar training, controllers separate traffic by relying on the estimated time over navigational fixes printed on flight progress strips, rather than monitoring the perceptually available positional information on a radar screen.
Objective: The main objective of this study is to present a methodology for computing information relevance.
Background: Relevance is a pervasive term used in several domains, such as pragmatics, information science, and psychology. Quantifying the relevance of information can be helpful in effective display design.
Objective: We present a snapshot of the work on situation awareness, which involves operators' comprehension of the dynamic situation that they are monitoring or controlling.
Background: Although human factors has always been concerned with helping the operator in his or her work environment, research exploded in the mid-1990s on one relevant construct, situation awareness.
Method: We discuss how a distinction present years ago, the product of comprehension versus the process of comprehension, not only continues today but characterizes different research directions.
