Where Is My Brain? Distributed Cognition, Activity Theory, and Cognitive Tools.

This paper provides a general overview of distributed cognition and activity theory in order to provide perspective for a discussion of the computer as a cognitive tool. Both distributed cognition and activity theory enlarge the scope of cognition to include the individual's interactions with the environment. Activity theory offers a framework congruent with distributed cognition that addresses some of its concerns. Despite the complexity of its vocabulary and concepts, it offers the potential for increased interdisciplinary exploration of issues related to cognitive tools. A table presents the division of labor between computers and single users as evidenced in computer roles, including computer roles ranging from servant to expert, goals (desirable outcomes), concerns (undesirable outcomes), and questions (contradictions).
