Prosodic structure and wh-questions.

This study examines the influence of wh-gaps on the prosodic contour of spoken utterances. A previous study (Nagel, Shapiro, & Nawy, 1994) claimed that the phonological representation of a sentence containing a filler-gap dependency explicitly encodes the location of the syntactic gap. In support of this hypothesis, Nagel et al. presented evidence that the word immediately preceding a gap is lengthened and that there is a reliable increase in pitch excursion across the gap location. Our study challenges Nagel et al.'s claim. We argue that their materials confounded the presence/ absence of a gap with other factors that are known to affect intonational phrasing independently. We show that, when these factors are separated, the evidence that syntactic gaps are explicitly encoded in the phonological representation of a sentence disappears.
