To date, the study of communicated explanations has been, at best, unsystematic. There has been little recognition that many, if not most, explanations are eventually delivered to a hearer or hearers. These potential audiences constrain the way the explanation is ultimately shaped. Similarly, researchers have devoted themselves to the study of "accounts," for the most part without an accompanying interest in the fundamental processes of event comprehension. This volume is devoted to bridging the gap between these two traditions.
