THE ROLE OF THE GRAPHEMIC BUFFER IN READING

We report the reading performance of an acquired dyslexic and dysgraph ic whose impaired spelling had previously been shown to result from da mage to the graphemic buffer. The analysis of this patient's errors in reading pseudowords indicates that this deficit may also be largely a ttributable to damage to a common graphemic buffer which is used both in reading and spelling words and pseudowords. The crucial evidence in favour of this hypothesis is the substantial presence of letter trans position errors in reading and spelling.
