Alcohol and the cognitive aspects of choice reaction time.
In a repeated-measures experiment 18 men and 8 women were given ethanol which raised their mean blood alcohol concentration (BAC) to 0, 21, 50 and 73 mg/100 ml. Using the ERM apparatus (Schuhfried Instruments, Austria), which measures choice reaction time to a task with high cognitive content, it was found that both decision and reaction time increased as a function of rising BAC, and that movement time was not affected.
