註釋Operator cognitive performance was quantified in an off-road environment by repeatedly administering a battery of cognitive measures to assess the genus and degree of performance while mobile. Environmental stressors referred to as endurance, tracked vehicle vibration per intensity, and noise were recorded over the course of one day per participant (n=18). Vibration conditions presented were varying amplitudes approximating accelerations of 0.88 g by a frequency of 3 cycles per second (cps), 0.65 g by 4 cps, and 0.03 g by 12.5 cps. Observed collectively, the predictor variables returned a multiple R value for the dependent variable percent correct of 0.733 (p
