ACQUIRED DYSGRAPHIA IN ALPHABETIC AND STENOGRAPHIC HANDWRITING

We report the unusual case of AZO, who professionally used handwritten shorthand writing, and became dysgraphic after a stroke. AZO suffered fron a complex cognitive impairment, and part of her spelling errors resulted from damage to auditory input processing, to phonology-orthog raphy conversion procedures and to the ortographic output lexicon. How ever, analysis of her writing performance showed that the same variabl es affected response accuracy in alphabetic and shorthand writing; and , that the same error types, including transpositions, were observed i n all tasks in the two types of writing. These observations are consis tent with damage to the graphemic buffer. They suggest that, in multip le-code writing systems (e.g., stenography, Japanese, or in the case o f multilingual speakers of languages that use different spelling codes ), the graphemic buffer is shared by all codes.
