    "Boundary-Driven Account for Downstep in Japanese"
     This study verifies the boundary-driven account for downstep in Japanese: downstep is triggered by phonological boundaries. The assumption widely adopted in the literature is that downstep is triggered only by accents. However, it remains unknown which account is more accurate. We propose that downstep is one example of the phonetic realization of boundary-driven downstep. We define boundary-driven downstep as a phonological mechanism that lowers the pitch of subsequent PPhrases when a PPhrase or a PClause directly dominates two or more PPhrases. Nine native speakers of Tokyo Japanese participated in a production experiment, which paradigmatically compared the F0 heights of a sequence of a final-accented word preceding an unaccented word to a sequence of unaccented words. The results showed that the condition with final accents without particles did not show a large F0 downtrend. Our finding indicates that accents do not directly trigger downstep.
