>For relatively high-risk/esoteric/cutting edge topics check >the literature on "Situation theory", "Ecological approaches >to Cognition". I think that area has a good chance of being >at least a mini-Kuhnian breakthrough pretty soon. Also related are Distributed Cognition and Activity Theory, which have similar models to the above. I think together they form a growing area of "post-cognitive psychology" that I find very interesting. In a sense, I think what Han suggests may almost have already happened - the paradigm shift away from looking at individual cognition to looking at cognition as a collective activity assisted by the environment, artefacts etc, is a big trend. Certainly in the field of CSCW (computer supported cooperative work) this is held to be more or less the norm. Those unfamiliar with these terms are recommended to read: Ed Hutchins, "Cognition in the wild", MIT Press, 1995 Bonni Nardi (ed), Context and consciousness: activity theory and human- computer interaction", MIT Press, 1996 Lucy Suchman, "Plans and Situated Actions", Cambridge University Press, 1987 Oh, and Susan Leigh Star has a *wonderful* paper that she published in the journal Systems Practice on these matters, but I don't have the reference. Taylor & Francis (London), publishers of the journal Behaviour & Information Technology, announce publication of "Computers, Communication and Mental Models", edited by Donald Day and Diane Kovacs. This book is a treatment of the cognitive and behavioural issues in computer-mediated communication, knowledge representation, and computer-supported co-operative work. It develops the theoretical basis for treating computerised tools as intermediaries in the communication of mental maps between tool builders and tool users. Work by specialists in psychology, human-computer interaction, communication theory, learning theory and group decision making is featured.
