“…Sounds can also be ordered when the interval between them is from 20 to 40 milliseconds, approximately (Kanabus et al,2002), however, this threshold can vary according to the parameters used in the task, such as inter-stimuli interval, for instance (Kanabus et al,2002). Furthermore, in certain populations, such as in the elderly (Neves, 2002;Mendelson & Riccketts,2001) and in children with language disorders (Rosen & Manganari, 2001, Borges & Schochat, 2005a, Furbeta & Felippe, 2005, where there is an alteration in the Auditory Processing, such threshold may also have a different value. Mendelson and Riccketts (2001) affirmed that an alteration in the fast processing of complex acoustic clues may be one of the reasons for the poor speech discrimination in the elderly.…”
