El papel del procesamiento morfológico en el reconocimiento léxico: Implicaciones de cara a una intervención logopédica en trastornos afásicos y lectores

The role played by morphological parsing in lexical access it is still not well known. There are many empirical results that support the view of it's great relevance, though there are authors that refuse this view. These authors, in a conexionist frame, consider morphology as a mere epiphenomenon, resulting from the semantic and phonological overlap that all morphological families imply. In the group of authors that consider the importance of morphological process in lexical access, there are many divergences. This divergences focus on their different ways for explaining the experimental results; time course of process and contextual circumstances that facilitate morphological process are the two more important sources of discussion. In this work we present and discuss experimental evidence supporting visual lexical access driven by sublexical-morphological information of polimorphemic words -made by and suffix and a stem-. These evidence, many times shown in aphasic and dyslexic patients, justify by itself those rehabilitation tasks that are created for improving morphological process.
