This study is part of a wider project analyzing the roles of prosody and anaphora in discourse organization in English and French, and linking production and perception. More specifically, the aim of this paper is twofold: it explores the interactions of prosody and anaphora in French discourse and their consequences in terms of cognitive processing cost for the hearer; these results are based on an indirect methodology which constitutes the second aspect of this work. More specifically, this study explores the interplay hypothesis between pronominal anaphora and the phonetic realization of intonation unit onsets using cross-modal semantic priming in French.
