Excerpt

This book is about the processing of information. The central domain of interest is face-to-face communication in which the speaker makes available both audible and visible characteristics to the perceiver. Articulation by the speaker creates changes in atmospheric pressure for hearing and provides tongue, lip, jaw, and facial movements for seeing. These characteristics must be processed by the perceiver to recover the message conveyed by the speaker. The speaker and perceiver must share a language to make communication possible; some internal representation is necessarily functional for the perceiver to recover the message of the speaker. That is, the perceiver must evaluate the external characteristics against some representation specifying the relationship between the audible and visible characteristics and the meaningful units of the message. On the basis of this process, some decision can be made about the intended message. The perceiver, in this regard, is processing information and this research is the study of information processing.

One claim is that the nature of the information processing can be studied without necessarily first knowing exactly what information is used. Logically, discovering what information is used cannot be determined without knowing something about information processing. Psychophysical methods, so useful for discovering what information is used, depend on some understanding of information processing. The current study integrates information-processing and psychophysical approaches in the analysis of speech perception by ear and eye.

The research framework is grounded in the testing of multiple hypotheses of the phenomena of interest. Binary oppositions are constructed and tested in a . . .
