Abstract
A case study investigates the writing, spelling and praxic skills of one patient who was found to have a selective impariment in his ability to write letters and words in the absence of difficulty in copying these same letters and words. He appeared to have difficulty accessing the correct motor programmes or sequences for writing which we term "ideational agraphia" analagous to the syndrome of ideational apraxia. These findings are related to Margolin''s information-processing model of writing.
