Participants used a position control system to track the center of a simulated winding roadway with preview that ranged from 0.3 to 1.0 s. Participants’ spatial distributions of attention were measured by perturbing the roadway with different frequency sinusoids at different roadway positions and then measuring the degree to which those frequencies were present in their tracking movements. Participants exhibited a continuous range of attention, and it lengthened with the amount of displayed preview. When preview disappeared for 5 s, longer time to regress to feedback control was strongly correlated with the amount of preview that was withdrawn. During preview withdrawal, visual sensory memory of the previewed roadway may be used for a fraction of a second to prolong the period of feedforward control. Attention may be shifted to relevant positions of the sensory memory image to anticipate the roadway curvature. The present methodologies may be useful in aviation contexts.
