It is based on a cognitive approach to writing and presents a writer-based perspective, as opposed to the analysis of writer’s final text or product. The focus of this article is to provide an overview of possibilities for writing process research made available by the rapid development of echnology. The article first presents computer keystroke logging as a relevant method among others, and discusses previous research based on the method.
