Two-Minute Peripheral Motion Contrast Threshold Test Predicts Older Drivers’ Collisions and Hazardous Driving in Simulator

Abstract

Older drivers’ contrast thresholds for low spatial frequency drifting Gabor stimuli at 15 degrees eccentricity were measured with a previously validated 10-minute forced-choice test and a 2-minute increasing contrast detection test (implemented on an iMac and a PC). Older drivers’ contrast thresholds significantly predict collisions, near collisions, hazardous lane excursions, and speeding, during a simulated drive with surprising hazard encounters and highway merging tasks. The 2-minute tests also correlate with each other and with the 10-minute test. The 2-minute tests are potentially suitable for use in an operational driver assessment setting.
