CHANGES IN SUBSIDIARY REACTION TIME AND HEART-RATE DURING CAR DRIVING, PASSENGER TRAVEL AND STATIONARY CONDITIONS

A reaction time (rt) task was used in three conditions, each lasting 2 h, during which six female subjects: (I) drove on a 5 km closed track, (II) were driven as passenger on the same track, and (III) were tested in a stationary vehicle. There was an increase in rt only in the driving condition. Furthermore, there was a progressively greater increase in rt over the three successive test sessions, independent of the order in which conditions were tested. Measurement of heart-rate (hr) showed that hr decreased only in the driving and the passenger conditions, and that the decrease in hr became progressively smaller over the three sessions. Consequently rt-data and hr-data (interpreted as indicating level of arousal) provided contra-indications of changes in driving proficiency.(a) /TRRL/
