Measuring linguistically-induced cognitive load during driving using the ConTRe task

This paper shows that fine-grained linguistic complexity has measurable effects on cognitive load with consequences for the design of in-car spoken dialogue systems. We used synthesized German sentences with grammatical ambiguities to test the additional workload caused by human sentence processing during driving. For the driving task, we used the Continuous Tracking and Reaction (ConTRe) task, which we believe is suitable for the measurement of...
