Abstract
Three versions of the Detection Response Task (DRT) were evaluated and compared as methods to assess cognitive demand while driving. Participants performed tasks known to manipulate cognitive demand (N_Back tasks) and realworld cognitive demand tasks using the iPhone interface, Siri, while driving a simulator. The Remote DRT, the Head Mounted DRT and the Tactile DRT were all sensitive to task demands but advantages were found to using the newer versions for the assessment of cognitive distraction. This work is part of an international collaborative research effort to standardize the DRT (ISO WD17488).
