Stress matters: Effects of anticipated lexical stress on silent reading

This paper presents findings from two eye-tracking studies designed to investigate the role of metrical prosody in silent reading. In Experiment 1, participants read stress-alternating noun–verb or noun–adjective homographs (e.g. PREsent, preSENT) embedded in limericks, such that the lexical stress of the homograph, as determined by context, either matched or mismatched the metrical pattern of the limerick. The results demonstrated a reading cost when readers encountered a mismatch between the predicted and actual stress pattern of the word. Experiment 2 demonstrated a similar cost of a mismatch in stress patterns in a context where the metrical constraint was mediated by lexical category rather than by explicit meter. Both experiments demonstrated that readers are slower to read words when their stress pattern does not conform to expectations. The data from these two eye-tracking experiments provide some of the first on-line evidence that metrical information is part of the default representation of a word during silent reading.
