Abstract
There is a current need to improve and expand options for reading intervention that support people with post-stroke aphasia. The present study used pre-existing eye tracking data, which tracked the reading behaviors of people with aphasia and neurotypical adults during story reading. The objectives of this analysis were to compare the eye movement patterns of each participant group, and to retrospectively describe an effect of a word predictability measure (surprisal) on eye movement across groups during story reading. Analysis revealed that people with aphasia had longer gaze durations and total fixation durations compared to neurotypical adults, which is consistent with previous findings of group effects in sentence-level stimuli. The positive effect of surprisal on probability of first pass fixation also aligns with previous studies of predictability and eye movement, but the negative effect of surprisal on probability of first pass regression, gaze duration, and total fixation duration contradicts much of the previous evidence on predictability effects. Additionally, no interactions of group and surprisal were found in this dataset, suggesting that neurotypical adults and people with aphasia respond similarly to the predictability of words during reading. While these findings could be attributable to the design of the original experiment or the current analysis approach, it is also possible that these findings are unlocking reading behaviors not previously shown in predictability literature. The current findings have the potential to inform future interventions for acquired reading impairment in post-stroke aphasia.
