A virtual reality test to evaluate dismounted soldiers’ cognitive and psychomotor performance in an operationally relevant setting

The developed test methodology offers a means to obtain embedded measures of SA, as well as shoot/do not shoot decisions, but VRT measurement appeared to be unreliable. Performance measures were not sensitive to effects of sleep deprivation, possibly due to a counteracting learning effect and limitations in timing of the post-test. The reliability checks of the SA measures were promising, indicating that this study contributes to advancing methodologies for evaluating human enhancement interventions on performance in operationally relevant settings. It is advised to incorporate team performance measures to enhance realism and integrate digitally obtained metrics to minimize observer bias.
