Side effects from acute and chronic alcohol consumption are well known. Paradoxically, however, the possibility that a moderate intake of alcohol may have a positive impact on secondary language learning has long been reported, and is also a popular belief. Recently, it has been reported that alcohol consumption improves the pronunciation of foreign languages as well as the memory effect. However, there is no definitive report on the mechanism by which alcohol is involved in memory enhancement and language learning. This review aims to provide an understanding of these effects and provide a blueprint for futher research by neurologically describing the mechanisms and possibilities that alcohol may have on language learning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
