In the most advanced stage of knowledge-crafting, the writer is able to hold in mind the
author’s ideas, the words of the text itself, and the imagined reader’s interpretation of
the text. The representations of the author, the text, and the reader must be held in the
storage components of working memory and kept active by allocating attention to them
(Traxler & Gernsbacher, 1993). Thus, for expert writers, not only are the basic processes
of planning, sentence generation, and reviewing juggled successfully, but so are three
alternative representations of content.
