title: MMN to natural Arabic CV syllables: 1-normative data.
abstract: Mismatch negativity response parameters; latency, amplitude, and duration to natural Arabic CV syllables differing in durational change (Baa-Waa) and in spectrotemporal change (Gaa-Daa) were obtained from normal hearing young adult Egyptians. The aim was to get normative data for MMN response parameters and to find any differences between both primary and non-primary auditory pathways in encoding and processing speech signals. Statistically significant differences between durational and spectrotemporal contrasts for latency and duration were found. This was attributed to acoustic differences and to physiological differences between primary and non-primary auditory pathways.
