Abstract

Understanding whether and how various processes interact in language production can help us both understand aphasic errors and develop theoretically motivated treatment approaches. We examined semantic errors produced in writing-to-dictation by an individual with acquired dysgraphia to determine whether letter-level information – particularly overlap between the target and the semantic error – can affect lexical selection processes in these errors. Our results indicated that the particular semantic errors that were produced were significantly more likely to share orthographic structure than would be expected by chance alone, indicating interaction in the form of feedback from letter-level processes to lexical selection.
