dc.description.abstractMany persons with aphasia (PWA), who have trouble communicating after a stroke, have difficulty naming objects, frequently producing speech errors. Picture (confrontation) naming tasks are commonly used to assess the presence and/or severity of naming difficulties, but these tests do not adequately capture the underlying cause of impairment. This project addresses the limitations of the standard picture naming paradigm by incorporating the measurement of eye movements, thereby providing a precise estimate of participants’ visual attention during the task. While prior studies have measured eye movements to distractor pictures when a spoken word is presented, to our knowledge no eye tracking studies have examined picture naming with written distractors in aphasia. Using a novel approach, we measured PWA’s and healthy controls’ eye movements as they selected the correct written word corresponding to the picture over other related words (semantically and sound-based distractors). The results of this project seek to: (1) indicate the feasibility of a novel eye tracking paradigm to study both intact and impaired lexical retrieval; (2) provide detailed information about the nature and time course of impaired naming; and (3) yield insight into the relative preservation of semantic and phonological representations in aphasia.en_US
