Changes in Marksmanship Performance on the WEAPONEER Trainer Caused by the Relative Frequency of Simulated Laser Exposure
Abstract
Earlier studies have shown that marksmanship performance is degraded by the requirement to respond appropriately to the presence of simulated scanning lasers and scanning/attack laser sequences. When no-laser, scanning- laser-only, and scanning-plus-attack-laser trials are mixed in equal numbers, accuracy is best on no-laser trials, declines on scanning-laser-only trials, and is worst on scanning-plus-attack-laser trials. In this study the ratio of the three trial types was systematically mixed: one group of subjects received a high ratio of scanning plus-attack to scanning-only and no-laser trials (4.6: 2. 5:1) while another group received a low proportion of laser trials (1:2.5:4.6 for scanning-plus-laser, scanning-only and no-laser trials). the high density group showed larger decrements in performance than the low density group on both scanning-plus-attack and scanning-only trials. Both groups of subjects showed significant improvement in performance with practice.
