J-SLA Vision Statement

We hereby establish the Japan Second Language Association (abbreviated: J-SLA) for the express purpose of promoting within Japan the advancement of research into second language development that seeks to elucidate the process of second language acquisition through theoretically grounded analyses of empirical data.

Our approach sees second language acquisition research as a scientific field of study on par with cognitive science, first language acquisition research, and linguistics, one that does not, therefore, depend on whether the findings have a direct application to foreign language education per se. Ascertaining the mechanisms of second language acquisition through a rigorous scientific method will contribute, along with other areas of cognitive science, to our understanding of human cognition.

Greetings from the President

Though Second Language Acquisition (SLA) research is still relatively new as a research field, a massive amount of data has been collected and has revealed lots of interesting findings. At the same time, the theories and research methods supporting the research field have diversified, and the approaches to SLA have become more complex. On the other hand, the rapid progress of data collection, methods of analysis and theoretical progress have clarified some of the important issues surrounding SLA, which has led to the creation of an environment where more constructive discussions can take place. In any case, the desire to investigate underlying phenomena of SLA and the goal of elucidating its mechanisms are common to all SLA approaches and methodologies. J-SLA will continue to strive to make SLA research of interest to as many people as possible and to provide a forum where we can share the joy of research and constructive discussions together.
