    El objetivo de este trabajo consistió en comprobar si los sujetos disléxicos muestran un déficit en el procesamiento de la información global en patrones organizados jerárquicamente, que está mediado por el sistema magnocelular. Además, se analizó si el color de fondo (rojo y verde) afecta de manera diferente al procesamiento de la información global en lectores normales, malos lectores y sujetos disléxicos. Los resultados muestran que el color de fondo parece deteriorar la precisión en el procesamiento global de los patrones jerárquicos, pero este deterioro se da en todos los grupos por igual. Los resultados no apoyan la teoría que defiende la existencia de un déficit en el sistema de procesamiento magnocelular en sujetos que presentan problemas de lectura.

    The aim of this work was to examine whether dyslexia is associated to a deficit in the processing of global information of hierarchical patterns which is mediated by the magnocelular system. Moreover, effects of color background on global information processing are tested in normal readers, poor readers and dyslexics. The results showed that red background color impaired global processing in ail three groups (normal readers, poor readers and dyslexics). These results are not congruent with the theory that proposes one deficit in the magnoceilular processing system in disabled readers.
