Alternatively, they might ve mere reflections of the task structures of communication networks, and could be obtained even if human subjects reacted 'automatically.' In order to resolve such ambiguity, a computer simulation model was constructed, separating the task structures and the artificial subjects' response characteristics. This simulation model roughly reproducted the findings of communication network studies in terms of the following: (a) the increased efficiency of non-centralized networks relative to the Wheel network in the case of high task-difficulty; (b) role-structures in the respective networks; (c) the positions of 'leaders' in several networks research can be understood to be reflecting the task structures of the experimental situaitons to some degree. Implications and limitaions of this study are discussed
