Abstract

We performed two experiments comparing the effects of speechproduction and speech comprehension on simulated driving performance. In bothexperiments, participants completed a speech task and a simulated driving taskunder single- and dual-task conditions, with language materials matched forlinguistic complexity. In Experiment 1, concurrent production and comprehensionresulted in more variable velocity compared to driving alone. Experiment 2replicated these effects in a more difficult simulated driving environment, withparticipants showing larger and more variable headway times when speaking orlistening while driving than when just driving. In both experiments, concurrentproduction yielded better control of lane position relative to single-taskperformance; concurrent comprehension had little impact on control of laneposition. On all other measures, production and comprehension had very similareffects on driving. The results show, in line with previous work, that there aredetrimental consequences for driving of concurrent language use. Our findingsimply that these detrimental consequences may be roughly the same whetherdrivers are producing speech or comprehending it
