ISBN 92-95003-16-0 Printed in Trieste by The Abdus Salam ICTP Publications & Printing Section iii PREFACE One of the main missions of the Abdus Salam International Centre for Theoretical Physics in Trieste, Italy, founded in 1964 by Abdus Salam, is to foster the growth of advanced studies and research in developing countries. To this aim, the Centre organizes a large number of schools and workshops in a great variety of physical and mathematical disciplines. Since unpublished material presented at the meetings might prove of great interest also to scientists who did not take part in the schools the Centre has decided to make it available through a new publication titled ICTP Lecture Note Series. It is hoped that this formally structured pedagogical material in advanced topics will be helpful to young students and researchers, in particular to those working under less favourable conditions. -

VII.C. Group Communication Through Electronic Media Fundamental
VII.C. Group Communication through Electronic Media* Fundamental Choices and Social Effects ROBERT JOHANSEN, RICHARD H. MILLER, and JACQUES VALLEE How will a given medium of communication affect the way in which groups of people communicate? What are the most promising near future directions for research considering this question? Our own incentive for exploring these issues began with a more specific concern about the probable social effects (and utility) of communication through a computerized conferencing system called FORUM, which is now under development at the Institute for the Future. The starting point for our inquiry was to consider computerized conferencing as a medium of communication, just as the telephone and face-to-face conversations may be considered media of communication. Not surprisingly, the criteria for evaluation of a medium of communication typically involve (either consciously or unconsciously) comparison with other media. Since the medium most familiar to the majority of us is face-to-face communication, there is an inherent tendency -for this to become the standard of judgment. One needs to exhibit great care when doing this, since computerized conferencing and other telecommunications media are not necessarily surrogates for face-to-face communications. It seems more likely that each medium will have its own inherent characteristics which should not be expected to mimic face-to-face patterns. On the other hand, comparison with -face-to-face communication is often crucial in order to understand a new medium: While most of the work in this area to date has been applied to conferencing media such as TV and voice systems, some of it has direct bearing on any future work in the computerized conferencing area. -
