While speakers tailor referring expressions to the knowledgeof their addressees, they do so imperfectly. Our goal here is toprovide an explanation for this type of pattern by extending aprobabilistic model introduced to explain perspective-takingbehavior in comprehension. Using novel production data froma type of knowledge mismatch not previously investigated inproduction, we show that production patterns can also beexplained as arising from the probabilistic combination of thespeaker’s and the addressee’s perspectives. These resultsshow the applicability of the multiple-perspectives approachto language production, and to different types of knowledgemismatch between conversational partners.
