There is growing evidence for data explanation models in speech processing. In these models, listeners generate expectations based on an internal model, differences between the input and the model have to be explained by attributing the difference to a cause, either the model, which must then be updated or an external cause. Having succeeded in explaining some part of the input, e.g., for example a pause or a disfluency as reflecting uncertainty or a distraction, how do listeners generalize to different speakers and different contexts. Michael Tanenhaus will outline a framework for exploring explanation and generalization. He will then outline how he propose to explore these framework in three domains: (1) speaker specificity effects in maintaining and breaking lexical precedents, i.e., using the same (maintain) or different (break) name; (2) using a name or a description (e.g., for kitchen utensils; and (3) interpreting gestures as grooming gestures or as gestures that convey supplementary information related to concurrent speech. In the first two domains, a crucial notion will be how speakers convey, and how listeners make attributions of, uncertainty.
