The role played by working memory (WM), that is, the capacity to temporarily maintain and cognitively process information, has been extensively studied in second language (L2) research. In a general sense, WM has been shown to be related to various aspects of L2 learning and use; however, little information is available regarding its relationship with L2 pronunciation. This study examines the relationship between the results obtained at a complex numerical WM task and the results from two French L2 pronunciation tasks, namely a reading-aloud task and a picture-based narration task, among 30 Mandarin-speaking adult learners. Results reveal that despite the absence of significant difference between the scores obtained from each pronunciation task, WM explained pronunciation observed in the reading-aloud task only.
