摘要

This paper is based on the ERP technology to study the emotional rhythm cognition mechanism of Tibetan Lhasa dialect in Emotional rhythm and emotional word matching. It was found that in the 150ms-250ms sad rhythm level, the titers mismatch stimulus pairs versus the titers-matched stimulus pairs induced a more positive N300. And this P200 effect was widely distributed in the scalp. In the 250 ms-350 ms time window, titers mismatch stimulus pairs versus the titers-matched stimulus pairs induced a more negative N300, and the distribution of brain area of this N300 effect was affected by the rhythm titers. When the background was happy rhythm, the N300 effect was distributed throughout the scalp area. When the background was sad rhythm, the N300 effect mainly occurred in the front and middle of the scalp. The 350ms-550ms time window, emotional rhythm and lexical titers mismatched stimulus pairs versus titers-matched stimulus pairs induced a more negative N400, manifested as a double-sided effect across the entire scalp distribution, and it was not affected by the rhythm titers. In addition, the response components including the P2 and N400 effected were more pronounced in sad rhythm. This was probably due to the fact that negative stimuli such as sad rhythm were more likely to attract the attention of individuals and required more psychological resources.
