title: Judging the implications of a concession: Conversational distance and belief bias effects.
abstract: An arguer's position at a given point in an argument can be characterized as a set of commitments. The present study considers the perceptions of ordinary language users about the implications of making a concession for the contents of the conceder's commitment set. In particular, we examine two sources of influence on such lay perceptions-conversational distance (i.e., the number of turns separating the concession from commitments incurred earlier in the argument) and an individual's prior beliefs regarding the content of the argument. Across two studies, college students were administered an argument task assessing the extent to which a concession by the protagonist of an argument on the last move indicated changes to other commitments incurred earlier in the argument. Results indicated that participants were more likely to judge a concession as indicating a change in prior commitments if (a) the commitment was incurred later in the argument than earlier, and (b) the participant disagreed with the protagonists' thesis in the argument. In addition, performance on deductive reasoning tasks predicted individual differences in the conversational distance effect, but not the belief bias effect.
