Executive Attention as a Predictor of Distracted Driving Performance

Abstract

The present study empirically examines the role of executive attention as a predictor of distracted driving performance. As ADHD is an attention-related disorder, we hypothesized that ADHD individuals would show poorer executive attention compared to individuals from a community sample. Second, we predicted that individuals with poorer executive attention would show riskier driving as measured by a self-report questionnaire and simulated driving trials. One-hundred thirteen individuals with and without ADHD completed an executive attention task, a driving behavior questionnaire, and three (pre-distracted, distracted, and post-distracted) simulated driving routes. Results showed that executive attention is associated with braking response times during distracted driving trials. There was also evidence for carryover effects of distraction, with participants showing slower braking response times even after the distracting task was discontinued. Further research is needed to clarify the relationship between ADHD and executive attention.
