ABSTRACT
This experiment examined whether the time of day of alcohol administration influences alcohol metabolism and the impact of alcohol on verbal memory. It was hypothesized that circadian fluctuations in endogenous levels of testosterone in young men would differentially affect blood alcohol levels, which would consequently impair their memory performance to a different degree. Participants were administered alcohol or placebo drinks either at 8am or 6pm and recall of 4 prose passages was examined. The results indicated that recall declined for subjects administered alcohol but time of day did not moderate these effects. Nevertheless, generally alcohol breath levels changed in the predicted direction as a function of the time of the day with higher levels recorded in the morning and lower levels in the afternoon. The results suggested that observed differences in breath alcohol levels may be influenced by differences in endogenous levels of testosterone, but the effect of this presumed interaction on verbal memory appears inconclusive.
