This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Heavy ('binge') drinking is common among college students and our research indicates that as many as 40% of college seniors believe that alcohol can enhance their academic performance. The proposed study will employ a two-period crossover design with block randomization to measure the effects of drinking (BAC .10) on the next-day academic performance of college seniors. Several studies, including our own, have indicated that even when blood alcohol concentrations (BACs) is at or near zero, occupational impairment can occur the morning after heavy drinking. Our studies to date have documented alcohol's residual effects using occupational training simulators to measure performance. The present study will focus on the residual effects of heavy drinking on both next-day academic performance (as measured by standardized academic achievement tests and a quiz on a lecture and reading presented on the previous day) and neurobehavioral performance (as measured by validated tests of cognitive impairment).
