Abstract
The ability to maintain vigilance in scanning the environment for improvised explosive devices (IEDs) can mean the difference between life and death for Soldiers. Although this ability to sustain attention varies among individuals, performance feedback training using knowledge of results (KR) has been found to improve performance. The present study builds on previous work on the influence of KR on vigilance training to investigate the efficacy of such training for improving upon performance and reducing workload and stress. Results indicated that the KR group achieved better vigilance performance than the No KR group and that the training benefits from KR persisted beyond the training phase. However, KR did not substantially affect perceived workload or stress response.
