Come Together: Integrating Perspective Taking and Perspectival Expressions

Author(s): Watson, Julia; Kapron-King, Anna; Aggarwal, Jai; Beekhuizen, Barend; Heller, Daphna; Stevenson, Suzanne | Abstract: Conversational interaction involves integrating the perspectives of multiple interlocutors with varying knowledge and beliefs. An issue that has received little attention in cognitive modeling of pragmatics is how speakers deal with the choice of words like come that are inherently perspectival. How do such lexical perspectival items fit into a speaker's overall integration of conversational perspective? We present new experimental results on production of perspectival words, in which speakers have varying degrees of certainty about their addressee's perspective. We show that the Multiple Perspectives Model closely fits the empirical data, lending support to the hypothesis that use of perspectival words can be naturally accommodated as a type of conversational perspective taking.
