By examining the relations among sections of the fundamental frequency contour used in judging an utterance as a question or statement, the experiment described in this report seeks a more detailed understanding of auditory-linguistic interaction in the perception of intonation contours. The perceptual process may be divided into stages (auditory, phonetic, phonological, syntactic, and semantic), but it must also be supposed that there is feedback from higher to lower levels which may serve to correct or verify earlier decisions. Perceptual "correction" of an auditory or phonetic decision, in light of a higher linguistic decision, will presumably not occur if the lower decision is firm. Details of the organization and results of an experiment (conducted with Swedish and American subjects) are presented here along with implications for further research. (Author/VM)
