Feedforward control ability as a predictor on driving performance under the restricted visual information in younger and older adults

Drivers must keep driving under the partially restricted visual information caused by pillars or bonnets. Under such constraints, feedforward control ability (FFCA) allows them to drive accurately. This study first evaluated drivers' FFCA on the basis of visuomotor tracking performance of a visible/invisible cursor-control with a joystick in the laboratory experiment. In addition, we examined to what extent the FFCA explains their driving performance in a circular driving experiment. A front pillar close to a driver occluded critical parts of visual scene (i.e., an inner line of the lane) in the right circling, relative to the left circling. Among younger drivers, high FFCA drivers kept their performance even during right circling, compared to lower FFCA drivers. Older adults' FFCA didn't predict their driving performance in the right circling. In this session, I also discuss the mechanism related to the age difference.
