This Introduction to the special issue first elaborates on the rationale for advocating the inclusion of L2 writing in SLA individual differences (IDs) research and subsequently provides an overview of empirical work on IDs in the domain of writing, with a focus on cognitive IDs and specifically working memory. Against this background, we synthesize the focus, structure, and contents of the special issue. We finish with substantive and methodological suggestions for moving forward in research agendas on IDs and L2 writing.
