Abstract
Aims: The alcohol hangover is typically investigated in student samples. However, alcohol hangovers are also reported by non-student drinkers, beyond the age and drinking behaviors of a student sample. The aim of this study was to investigate the effects of a normal night of alcohol consumption on next-day cognitive performance in a non-student sample.
Methods: Participants (N = 45) were recruited from a public drinking setting and participated in a naturalistic study comprising of a hangover test day and alcohol-free control day. On each test day, mood and hangover severity were assessed and participants completed a cognitive test battery consisting of a Stroop test, Eriksen's flanker test, spatial working memory test, free recall test, choice reaction time test, and intra-extra dimensional set shifting test.
Results: On the hangover day, significantly impaired performance was revealed on all tests, except the intraextra dimensional set shifting test. On the hangover day, significantly lower mood scores were observed for alertness and tranquility.
Conclusion: The current study in a non-student sample confirms previous findings in student samples that
cognitive functioning and mood are significantly impaired during alcohol hangover.
