We use pupillometry to examine the time-course of sentence processing in aphasia, perhaps the first study to do so.  By time-locking pupillary responses to stimulus presentation, we are able to collect a continuous measure of processing load in a participant-friendly and efficient manner.  In this first proof-of-concept effort, we manipulate the thematic fit that occurs between a verb and its arguments. We find that aphasic patients’ pupillary responses are similar to those of their age matched controls as well as healthy college age students, whereby pupil size increases when thematic fit is violated.
