| Abstract: | The theory is advanced that reduction transformations function to provide speakers with the option of deleting redundant information when communicating to a topic-cognizant addressee and/or when using a written mode. To test the theory, an experiment was run in which subjects from an advanced cell physiology class were given a list of deep structure proximal sentences (base propositions), all pertaining to the topic of cellular energy, and were asked to communicate them, in either a written or oral mode, to either graduate students in biochemistry or freshman nonscience majors. An analysis of the subjects' use of reduction transformations when communicating the base propositions supported the redundancy-deletion theory developed in the paper. The implications of these results for the perceptual complexity theory of reduction transformations (Fodor & Garrett, 1967) are discussed. |
