This paper describes the case of a unilateral agraphic patient (GG) who makes letter substitutions only when writing letters and words with his dominant left hand. Accuracy is significantly greater when he is writing with his right hand and when he is asked to spell words orally. GG also makes case errors when writing letters, and will sometimes write words in mixed case. However, these allogra...

AIM this study aimed to characterize the fine motor, sensory and perceptive function of school-aged children with dyslexia, learning disabilities and learning difficulties and to correlate these results with the analysis of the children's handwriting. METHOD participants we...

Previous research has shown that damage to the neural substrates of orthographic processing can lead to functional reorganization during reading (Tsapkini et al., 2011); in this research we ask if the same is true for spelling. To examine the functional reorganization of spelling networks we present a novel three-stage Individual Peak Probability Comparison (IPPC) analysis approach for comparin...

This paper addresses the issue of the structure of graphemic output representations via an analysis of the spelling performance of a patient with acquired dysgraphia. It is argued that the patient’s pattern of performance with words that contain double letters (e.g., ‘‘bb’’ in ‘‘rabbit’’) is inconsistent with the view that graphemic representations are simple linear sequences of graphemes (or a...
