title: On the role of rarity information in speakers' choice of frame.
abstract: In this article, we examine conversational behaviors when people describe the outcomes of uncertain events. We propose a new hypothesis, frame choice based on rarity information, that is built on the basis of one prominent measure of informativeness (i.e., self-information). The hypothesis predicts that when speakers can choose one of two logically equivalent frames for describing the outcome of an uncertain event (e.g., the results of the roll of a die or a medical operation), they prefer the frame denoting an event that is known or perceived to be rare. Four experiments using frame choice tasks provide evidence that speakers' choice of frame is explained well by the rarity hypothesis.
