Traditionally, driver distraction has been categorized into four types: visual, biomechanical, auditory, and cognitive. However, the place of emotion in distracted driving research is undefined. This research investigates the influence of emotional distraction on driving performance. In total, seventy-eight participants were recruited and placed into one of four conditions: physical (visual-biomechanical), cognitive (cognitive- auditory), emotional (anger), and control. The results demonstrated that emotional distraction degrades driving performance as much as or more than other distraction types. The causes for these results, underlying mechanisms, and other considerations are mentioned in the discussion section.
