• Abstract:
  In each of two independent experiments, four high extraverts and four lower extraverts drove an instrumented car through a closed pylon-defined course, on each of two experimental days, after ingestion of alcohol and a placebo beverage, and with and without a concurrent mental loading task requirement. The direction and magnitude of the influences of alcohol upon tracking accuracy and control-use behavior depended upon the particular controls observed, and was associated with driver personality and driver priorities concerning accuracy and speed. Alcohol significantly increased accelerator use regardless of personality or priorities, whereas the influences of alcohol upon steering behavior seemed more susceptible to individual differences. In one study, the loading task requirement significantly reduced the accuracy-degrading effects of alcohol, whereas in the subsequent study, it did not. Heart-rate variation was reduced by alcohol.
