I will outline the rationale for using eye-movements to study spoken language, using natural tasks with visually co-present displays or real objects. I will begin by discussing how the visual world paradigm allows cognitive scientists to unify two different traditions in language processing: the language-as-product tradition which emphasizes the importance of studying time course and the language-as-action tradition which emphasizes the importance of studying language in natural contexts, including interactive conversation. I’ll review some classic results from my laboratory and outline some important question and issues for the coming decade, where the visual world paradigm will play a central role.

For most of the last two decades two classes models have dominated the spoken word recognition literature: (1) pattern recognition models with abstract representations, and (2) exemplar-based pattern recognition models. I will argue for another class of model: “data explanation” models that evaluate hypotheses about the state of the world according to how well those hypotheses predict the observed properties of the perceptual input. I will outline an explanation-based framework in which prediction and learning play a central role and present supporting evidence from two lines of work. The first examines listeners’ use of pre-word onset anticipatory co-articulation. The second examines listeners’ use of “distal prosody” in generating and evaluating lexical hypotheses.
