Stress and context in auditory word recognition

Recent work in psycholinguistics has revealed that the role of lexical stress in auditory word recognition may be a complex one involving other potential sources of information. In the present investigation, the nature of lexical stress effects on auditory word recognition in context is examined. The ability of subjects to identify words based on the prosodic pattern of the word is examined for the words in isolation and in a sentence context. The results revealed a small influence of stress on the identification of the stimulus waveforms relative to a large effect of context. The data indicate that lexical stress is used in the identification of the words; however, its role is minor compared to the importance of contextual information.This article is based on sections of a doctoral dissertation presented to Indiana University, Bloomington, Indiana.
