Second Language Research is an academic journal dedicated to second language and extra language acquisition, aimed at providing a forum for researchers in the field of non-native language learning and promoting interdisciplinary research. This journal publishes theoretical papers, original research, and review articles covering various aspects of simultaneous or continuous second language and extra language acquisition in both children and adults.

It not only focuses on traditional fields such as theoretical linguistics, neuroscience, cognitive science, and psycholinguistics of first language development in second language acquisition, but also actively explores non applied fields related to second language acquisition, such as psychology, sociology, anthropology, etc. By promoting interdisciplinary research, this journal aims to deepen the understanding of second language acquisition, drive the development of related fields, and provide scientific basis for educational practice.
