Summary
The primary objective of the study is to assess the benefice of Vyvanse on the factors that
cause impairments in driving behavior in individuals with ADHD using a driving simulation
aimed at examining the factors that cause impairments in driving behavior in individuals with
ADHD such as driving speed, collision risk, and visual attention of 60 young drivers (ages
18-24) with ADHD. We hypothesize: 1.) young adults with ADHD treated with Vyvanse will show
lower velocity (speed) scores and spend less time driving over the posted speed limit in the
driving simulation when compared to subjects taking a placebo; 2.) young adults with ADHD
treated with Vyvanse will show a lesser likelihood to collide with a suddenly appearing
peripheral object, less difficulty maintaining the vehicle within their lane, and a lesser
likelihood of driving through stop signs and solid red traffic lights without slowing down
when compared to subjects taking a placebo; and 3.) young adults with ADHD treated with
Vyvanse will exhibit more focused visual attention on details in the visual field when
compared to subjects taking a placebo while driving. In addition, young adults with ADHD
treated with Vyvanse will exhibit less visual tunneling and shorter off-road glances when
compared to subjects taking a placebo.
