Abstract

In this article, the authors examine the sensitivity of the Detection Response Task (DRT) to cognitive and visual-manual tasks of different levels of difficulty and to different levels of driving demand. The DRT is being considered as a strategy for assessing the impact of cognitive load on driver attention. For this study, one tactile version and two visual versions of the DRT are considered. Sixteen individuals participated in the study, which consisted of two driving scenarios and two types of secondary tasks of varying difficulty. Response time to DRT stimuli are found to increase with driving demand and with cognitive auditory task difficulty. In contrast, the results show no difference between visual-manual tasks of varying difficulty. The authors describe a possible ceiling effect of the DRT's sensitivity to discriminate between task levels of difficulty.
