Too harts, won sole: Using dysgraphia treatment to address homophone representation.

Previous spoken homophone treatment in aphasia found generalization to untreated homophones and interpreted this as evidence for shared phonological word form representations. Previous written treatment of non-homophones has attributed generalization to orthographic neighbours of treated items to feedback from graphemes to similarly spelled orthographic word forms. This feedback mechanism offers an alternative explanation for generalization found in treatment of spoken homophones.
