Abstract
Most research on writing has focussed on the work of single authors working by hand on prose texts. However, much professional work is collaborative, computer-based, not exclusively prose, and not well studied. Some preliminary research suggests that the use of computers will affect the cognitive activities of individual authors in several domains of immediate relevance to composition and technical communication practitioners: planning activities, editing activities, the writing of novice computer users or poor typists, and writing for electronic mail and other electronic communication. Research reported here suggests that the rapidly increasing capability of computer-based writing systems will force communication researchers to 1) broaden their basic conception of and methods of studying “author” to include authoring teams, 2) broaden the type of material studied from that which is purely or largely textual to that which much more frequently includes other types of information, and 3) track changes in “genre conventions” resulting from the increased capabilities of computer-based systems—in short, to assess the impacts of the medium on the message.
