N2 - Background: Perceptual span refers to the field of effective vision during reading comprehension. It is determined by many factors, including reading proficiency. No studies have investigated the perceptual span in people with reading comprehension impairments due to aphasia. Aims: The present study examined whether perceptual span is smaller in individuals with aphasia than controls. Methods and Procedures: The task was a gaze-contingent moving windows paradigm during silent reading using an eye tracker. Data from 11 individuals with aphasia and 15 neurotypical controls were analyzed. Outcomes and Results: Perceptual span in individuals with aphasia was the fixated word plus one word to the right of fixation, whereas perceptual span in controls was the fixated word plus two words to the right of fixation. Conclusion: Individuals with aphasia have a smaller perceptual span than controls, which likely reflects increased effort during reading comprehension.
