Previous studies have shown that alcohol significantly impairs driving performance. Acute alcohol administration also has a detrimental effect on secondary task performance during dual-tasks. The present study will investigate the effects of five different dosages of ethanol (0,0.2, 0,5, 0,8 and 1,0 % BAC) on performance in a driving simulator. Steering performance and brain activity will be recorded in both single- and dual-task conditions.

Further study details as provided by Utrecht Institute for Pharmaceutical Sciences:

Primary Outcome Measures:
  • Primary parameter of the steering simulator is the standard deviation of the car from the center of the road (steering error). [ Time Frame: 5 testdays ]

Secondary Outcome Measures:
  • Reaction speed after hearing the deviant target tone. Brain activity: ERPs of interest are the mismatch negativity (MMN), P3a, P3b, and reorienting negativity (RON) [ Time Frame: 5 testdays ]
