Abstract: This chapter explains an important part of our efforts to find the possible relationship among alterations in Central auditory processes (CAP) and phonological dyslexia. The main part of our work was carried-out in empirical, descriptive, and comparative studies among children with dyslexia when they are confronted in their performance in CAP tasks and others examinations such as psychological and electrophysiological tests with healthy controls children. Our working definition of dyslexia is that this alteration is present when the automatization of word identification (reading) and/or word spelling does not develop, or that it does so incompletely or with great difficulty (Gerson-Wolfensberger and Ruijssenaars, 1997). The main alterations according to our hypothesis is the difficulty in the temporal analysis of auditory stimuli, including those contained in language. This was noted specifically in tests with words that are time compressed, in the Masking level difference (MLD) test, and in the identification of auditory stimuli in a changing or noisy environment such as in white noise background.
