The major areas of concern in this paper are the information and aesthetical impacts of artwork on the human mind, and the modes, structures, and media of artwork which influence the formulation of aesthetical impact. The analysis of aesthetical information impact follows current discoveries in the disciplines of biocybernetics, system and information theories, and neuro- and psycho-physiology. Phases of the mental process which can influence the notion of aesthetical impact are examined, and it is noted that this impact may have its origin in one or all three major parts of the information chain--the artwork itself, the environment in which the artwork is intercepted, and/or the viewer (observer) and his or her past experiences, memories, or systems of thinking. Also explored are the differences in the process of aesthetical impact formulation from different kinds of artwork, i.e., pictures, books, music, film, or television programs; differences caused by different modes of delivery, e.g., direct experience (book), performance (theater), or substituted transmission (television); and differences arising from the structure of the artwork itself. The creation of an aesthetical profile of artworks, regions, or audiences is briefly discussed and a proposal for research in this area is outlined. A bibliography is attached. (RAO)
