Improved memory for information learnt before alcohol use in social drinkers tested in a naturalistic setting

Abstract Alcohol is known to facilitate memory if given after learning information in the laboratory; we aimed to investigate whether this effect can be found when alcohol is consumed in a naturalistic setting. Eighty-eight social drinkers were randomly allocated to either an alcohol self-dosing or...
