The main stream of research on relations between people and their physical surroundings is still expected to set up scientific support to architecture and environmental design. In spite of the ongoing strive for communication between the disciplines, this aim has not been achieved yet. This paper intends to examine the problem from a theoretical point of view, in order to clarify that miscommunication is not a consequence of instrumental or methodological deficiencies, but can be explained by the inherent gap between different spheres of knowledge. The discussion is based upon a model of knowledge (after G. Ryle, 1946). This model, applied to architecture, shows the potential channels of communication between specific spheres of knowledge in architecture and E-B studies, The results of this analysis negate the very basic premise held by both E-B scientists and architects, that direct utilization of research results in architectural practice is possible and desirable. The paper concludes by illustrating the nature of different channels of influence between architects and E-B scientists.
