Tactile detection response task: Metrics for assessing drivers’ cognitive workload

摘要: Abstract The Tactile Detection Response Task (TDRT) has been used to assess the cognitive workload of driver distraction with response time and miss rate as metrics workload. However, it is not clear which metric more sensitive whether sensitivity maintained for visual tasks. objective this study was TDRT changes in examine depends on task modality. A driving simulator conducted 24 participants. included restaurant selection tasks three presentation modalities (auditory, visual, hybrid) two difficulty levels (low high). high level designed be cognitively demanding than low level. Mixed-effects models were applied model controlled age group, gender, a random effect auditory significantly increased likelihood missing stimulus. No statistically significant differences observed hybrid associated level, regardless In study, binary outcome thus considered time. can still measure when are relatively easy close zero. addition, diminished that involved component. Researchers who use should aware limitation.
