Organized under the auspices of the "Language Learning" Roundtable Conference Grant (2012), this seminar aimed to provide an interactive forum for a group of second language acquisition (SLA) researchers with particular interests in cognitive linguistics and psycholinguistics to discuss key theoretical and methodological issues in the roles of key human memory systems (in particular, working memory) in various aspects of SLA. The seminar consisted of a tutorial workshop (Michael Ullman), three keynotes (Michael Ullman, Peter Skehan, and Cem Alptekin), and other invited speeches addressing the more specific relationships between working memory (WM) and various aspects of SLA (e.g. vocabulary, grammar, reading, speaking, writing, and interpreting).
