Overview

Cardiac measures may miss visual occlusion effects on simulated driving workload; leaves open their sensitivity to curve radius demands in wider populations.

Structured PICO

Does visual occlusion during simulated driving affect cardiac measures of driver workload in male university students?

Population

15 male university students

Intervention

Simulated driving with visual occlusion of the road scene on a course with curves of 3 different radii (582, 291, and 194 m) at a fixed speed of 72.4 km/h

Comparator

Simulated driving without visual occlusion on the same course

Outcome

Cardiac measures (heart rate, pre-ejection period, and respiratory sinus arrhythmia), driving performance, and visual demandsurrogate

The combination of psychophysiological and visual occlusion methodologies can isolate perceptual demands from central and motor processing demands during driving.
