Led by Bryan Reimer, a team of AgeLab and Massachusetts General Hospital researchers studied how individuals with and without attention deficit hyperactivity disorder (ADHD) are distracted by secondary tasks while driving. Drivers with ADHD were found to have more difficulty with using a cell phone while driving, though their driving performance was not affected anymore than it was for subjects without ADHD. Attention allocation by drivers with ADHD depended greatly on demand setting and what type of secondary task they were performing. This, in turn, affected their driving performance. Findings suggested that drivers with ADHD were more easily distracted during periods of low stimulus driving.
