Problem-solving approach to agraphia treatment: Interactive use of lexicaland sublexical spelling routes

Two patients with acquired spelling impairments due to left hemisphere brai n damage participated in a treatment protocol to improve their written spel ling. Prior to the initiation of writing treatment, both patients showed so me ability to take advantage of sound-to-letter correspondences that result ed in phonologically plausible spelling errors. A homework-based treatment was implemented to improve their ability to resolve spelling errors by incr eased reliance on phoneme-to-grapheme conversion, self-correction, and use of an electronic speller. Both patients improved their spelling abilities a nd provided evidence of interactive use of partially spared lexical and sub lexical spelling routes to resolve their spelling difficulties.
