Abstract: | This study was conducted to determine the impact of noise on target detection, identification, and marksmanship (TDI&M) and to examine the effectiveness of a monetary reward to improve performance. Twenty active duty male soldiers participated in a non-reward and reward trial, each comprising three time blocks of two alternating 20-minute sessions, one with 87-dBA battlefield noise and the other relatively quiet. Each session involved 15 minutes of TDI&M testing followed by 5 minutes of rest. Neither noise, time on task, nor reward caused any noteworthy changes in TDI&M performance, except for foe target engagement time (ET). It appears that subjects purposely increased ET over the duration of the task to improve their hit accuracy but did not succeed in doing so. The monetary incentive to improve performance was also ineffective, because the subjects applied a similar “best” effort during the no-reward trial prior to this manipulation. |
