The present study tested whether earlier reported effects of alcohol on simple auditory and visual reaction time in a vigilance setting should be attributed to the pharmacological properties of alcohol or to subjects' expectancies as to the acute effects of alcohol. Results indicated that an expectancy interpretation can be excluded.
