Abstract

In a field study, we examined turn signal use characteristics during highway-lane changes across three age groups (20-29, 40-49, and 60-69) and under varying levels of secondary cognitive demand. Secondary cognitive demand decreased the likelihood of turn signal use, and delayed the onset and turnoff of the turn signals. These results suggest that added cognitive load can lead to a neglect of operational tasks in face of competition over limited resources. No major effects of age or relative level of secondary cognitive demand were observed. (Author/publisher)
