Thank you for checking out my poster! Be sure to watch the video for a walkthrough. Email me with any questions: jburnsky@umass.edu Also, please make use of the comments button in the upper right corner of your screen when viewing either the poster or the video. These questions will be visible to the public as will my responses. Here's my short abstract: In two sentence completion experiments, participants read embedded wh-questions such as “The nurse knew which patient the doctor had been …” and were provided with 2 options for the embedded verb. These options differed in their voicing (“treating” vs. “treated by”) and thus their plausibility, and also in their predictability (“treating” vs. “hugged by”). We found that participants tended to select the predictable option (with "treat" as the stem) even when this resulted in a plausible sentence only under an incorrect assignment of thematic roles to the embedded arguments. We take this to show that there is genuine uncertainty in incremental thematic role assignment.
