Hart, Sandra G. and Battiste, Vernol (1992): Field Test of Video Game Trainer. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 1291-1295.
A field study was conducted at the US Army Aviation Center to determine whether workload-coping and attention-management skills developed through structured video game experience would generalize to flight training. Three groups of 24 trainees were compared (1) One received 10 hours of training on an IBM-PC version of Space Fortress, replicating an earlier study; (2) The second played a commercial video game (Apache Strike) for 10 hours which also required tracking, monitoring, situation assessment, and memory; (3) The third matched group receive no game training. Flight school records were monitored during the next 18 mos to compare performance of the three groups during initial flight training. Check ride ratings began to show an advantage for the group trained with Space Fortress by the Instrument stage of training, as predicted. Furthermore, attrition rates were lower for this group, replicating the results of an earlier study conducted by Gopher (1990) in the Israeli Air Force Flight School.

Casper, Patricia A., Shively, Robert J. and Hart, Sandra G. (1987): Decision Support for Workload Assessment: Introducing WC FIELDE. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 72-76.
Currently there is a great demand for mental workload evaluation in the course of system design and modification. In light of this demand, a microprocessor-based decision support system has been created called WC FIELDE: Workload Consultant for FIELD Evaluation. The system helps the user select workload measures appropriate to his or her application from the large pool of currently available techniques. Both novices and those with some workload experience may benefit from using WC FIELDE, since the system's operation is entirely transparent and all rules involved in the decision process are available for the user to examine. WC FIELDE recommends several assessment methodologies in decreasing order of appropriateness, and provides additional information on each measure at the end of the program in the form of text files.

Johnson, Walter W. and Hart, Sandra G. (1987): Step Tracking Shrinking Targets. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 248-252.
Four models describing how people might acquire targets that dynamically vary in size were examined; two that described movement speed as a simple function of target size (either initial or final) and two that described movement speed as a function of the predicted size of the targets at a fixed time in the future (one was referenced to the beginning of the reaction time phase, and the other to the end of this phase). It was found that movement time was best described as a function of a size prediction made at the end, rather than the start, of the reaction time phase. Subjective workload ratings primarily reflected the total amount of time needed to acquire the targets rather than the time pressure imposed by the diminishing size of these targets.

Kantowitz, Barry H., Bortolussi, Michael R. and Hart, Sandra G. (1987): Measuring Pilot Workload in a Motion Base Simulator: III. Synchronous Secondary Task. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 834-837.
This experiment continues earlier research (Kantowitz, Hart,&Bortolussi, 1983) conducted in a GAT-1 motion-base trainer to evaluate choice-reaction secondary tasks as measures of pilot workload. The earlier work used an asynchronous secondary task presented every 22 sec regardless of flying performance. The present experiment uses a synchronous task presented only when a critical event occurred on the flying tasks. Both 2- and 4-choice visual secondary tasks were investigated. Analysis of primary flying-task results showed no decrement in RMS error for altitude, indicating that the key assumption necessary for using a choice secondary task was satisfied. Reaction times showed significant differences between Easy and Hard flight scenarios as well as being able to discriminate among flight tasks.
