Description: This is a data depository for Rich, T. & Palmer, J. (2021). Spatial and Attentional Contributions to Peripheral and Foveal Word Recognition in Patients with Neglect Dyslexia. Submitted for publication. Abstract Many patients with right hemisphere stroke fail to read words closest to the left margin of text and/or commit within-word errors on left-sided letters while correctly reporting right-sided letters, a condition known as neglect dyslexia. These patients also show non-spatial deficits of selective attention, which might be a contributing factor to these errors. The purpose of this study was to determine the relative contributions of spatial processing deficits and selective attention deficits on word recognition errors in neglect dyslexia. In Experiment 1, we replicated studies that showed poorer accuracy for target words when presented alongside a competitive distractor word than when presented solitarily. The effect of a distractor word was larger for target words on the left. In Experiment 2, we modified the paradigm so that the target word was positioned centrally at fixation in all conditions, in an effort to minimize spatial effects. Patients performed worse under conditions with a distractor word regardless of the side on which the distractor was presented. These findings are consistent with the errors in neglect dyslexia being at least partly due to a selective attention deficit.
