INVESTIGATE THE EFFECTS OF DRIVING STRESS ON HEALTH. FINAL REPORT
This project concerned the relationship between age, cognitive deficits, and driving performance under varying workload conditions. Older and younger subjects were administered a battery of tests designed to assess information processing skills, and personality traits that were thought to underpin driving competence. Subjects then drove through a programmed course on a driving simulator. At different intervals during the drive subjects were required to perform subsidiary tasks of varying levels of difficulty. Dependent variables included measures of driving performance, heart rate measures, and subjective stress measures. Data indicated that workload manipulations affected driving performance, physiological responses and subjective stress indices of both older and younger drivers. The relationship was in many instances mediated by age, cognitive skills, and personality factors.
