Abstract: Acute alcohol consumption has been found to cause duration perception distortions, but the directions of these distortions are not consistent. The mechanisms underlying this effect are also unclear. The present study seeks to elucidate the effect of acute alcohol consumption on duration perception and the mechanisms involved. Forty-one participants in the placebo group and 40 in the alcohol group completed time bisection tasks, attentional network tests, digit span backward tests and arousal reports to evaluate their duration perception, attentional network, working memory capacity and arousal. The results showed that the alcohol group overestimated duration compared to the placebo group. The alcohol group also showed increased arousal, impaired executive control of attention and reduced working memory capacity. Arousal mediated the effect of acute alcohol consumption on duration perception, whilst working memory capacity masked this effect. The findings are discussed based on the Scalar Timing Model and the Cognitive Resource Allocation Model.
