Comparison of Velocity Detection in Young and Older Observers in a Simulated Night Driving Situation


Thresholds for detection of angular velocity were determined in young and older observers for a target simulating the motion-in-depth of a motor vehicle at night. Thresholds were determined for a range of target sizes and for central and peripheral viewing conditions. We found significant differences in thresholds between these groups with the older subject group performing worse. Angular velocity thresholds increased with target angular size and with peripheral viewing.
