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 intra-extra 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.
