Source Localization of Preattentive Processing for Different Vowel Duration Changes with Contour Tones in Monosyllabic Thai Words
Wichian Sittiprapaporn

Abstract:
The objective of this study was to investigate that the Mismatch Negativity (MMN) can be used to provide an index of experience-dependent and long-term memory traces for different vowel duration changes with contour tones in monosyllabic Thai words. Twenty-two healthy right-handed adults participated in this study. It was found that the long-to-short vowel duration with falling and rising tone changes elicited a strong MMN bilaterally for both native and nonnative speakers of Thai, unlike short-to-long vowel duration with falling and rising tone changes. Source localization analyses demonstrated that sources were obtained in the Middle Temporal Gyrus (MTG) of the left hemisphere and in the Superior Temporal Gyrus (STG) of the right hemisphere for both subject groups.
