- Abstract
- (en) [The graphemic buffer disorders: From cognitive theory to clinical assessment] Various mental operations are required to convert a spoken word into a sequence of handwritten letters. One of them, the graphemic buffer is an orthographic working memory store which keeps active the orthographic representations issued from lexical and nonlexical routes for as long as required to produce the letters in different output modalities (retrieving graphic stroke sequences for writing, finding the correct letter on the keyboard for typing, or saying the letter name for oral spelling). In this paper, the graphemic buffer will be first located in a basic architecture of spelling and the main characteristics of their impairements will be summarised. Particular attention will be paid to the contribution of data issued from disorders of the graphemic buffer to our knowledge of the structure of the orthographic representations. Lastly, some guidelines will be provided to the clinicians to identify an impairment at this level of processing. We will outline the most relevant spelling tasks to choose, the linguistic variables to control and the quantitative and qualitative analyses to realise.
