Abstract

Reaction times (RTs) of aiming movements are typically shorter when responses are prepared by informative precues. Aside from RT facilitation, response preparation can also modify the velocity profile of the movement trajectory. In this study we assess the preparatory effects of advance information about direction and number of lanes in a lane change task. Consistent with the findings of previous studies with aiming movements, prior information reduced RT and affected the velocity profile of the steering angle. The velocity profile was mainly shortened around the first peak steering wheel angle, and this finding is in line with the movement integration hypothesis. The results suggest that the findings from basic research can be generalized to driving tasks.
