Effects of speed of visual processing training upon non-visual attention in "at-risk" older drivers.

This paper describes a preliminary study to determine whether training in visual speed of processing can improve performance in attention-demanding tasks processed outside the visual domain. Subjects were assigned to a group receiving training in speed on visual processing or to a control group, and performed a version of the Paced Auditory Serial Addition Task (PASAT). Training of speed of visual processing improved performance on both visual attention tasks and the PASAT. This finding may be relevant to performance in certain tasks during driving.
