%0 Journal Article %T Re-Defining Dyslexia: Accounting for variability/Redefiniendo la dislexia: explicando la variabilidad %A Cyril R. Pernet %A Olivier Dufor %A Jean-Francois D¨¦monet %J Escritos de Psicolog¨ªa %D 2011 %I Universidad de M¨¢laga %X The scientific effervescence that reigns around developmental dyslexia is explained by the difficult challenge that consists of ascribing this handicap to a single cause whilst multiple profiles of dyslexic patients can be observed. In this chapter, we start by presenting the main neuro-cognitive hypotheses that aim to explain dyslexia. We then review the multidimensional nature of dyslexia, and discuss the necessity of using a common diagnostic criteria to improve our understanding of its true nature. We then conclude by presenting promising work connecting cerebral endophenotypes and behavioral phenotypes highlighting the need for a multi-factorial rather than mono-theoretical account of developmental dyslexia. %K Developmental dyslexia %K Multi-factorial deficit %K Review. %U http://www.escritosdepsicologia.es/descargas/revistas/vol4num2/i_vol4num2_3.pdf
