“…Investigations of this topic have focused above all on revision (reading in order to assess the text produced so far- Butterfield et al, 1996;Hayes et al, 1987) and the summarizing of documents (reading and analyzing sources in order to develop text content-M. L. Kennedy, 1985;McGinley, 1992;Nash, Schumacher, & Carlson, 1993). A variety of methods have been used, including comparing the writing performance of poor and proficient readers (McCutchen, Francis, & Kerr, 1997); analyzing the strategies adopted by writers in order to draw on either the text produced so far or the sources, by filming the writers' activity (O'Hara, Taylor, Newman, & Sellen, 2002) or by recording concomitant verbalization (Breetvelt, van den Bergh, & Rijlaarsdam, 1996); eliminating or altering visual feedback using invisible ink or masks in order to record the effects on the quality of the text (Dansac & Passerault, 1996;Hull & Smith, 1983;Olive & Piolat, 2002); and controlling access to sources so that the writer has to stop writing in order to view sources on a computer screen (Dansac & Alamargot, 1999).…”
