title: Do metrical incongruities disrupt semantic processing in modern Chinese? An event-related potential study.
abstract: The present study examined the relationship between prosody and semantic processing in the written form of modern Chinese by analysing behavioural data and event-related potential data. By manipulating the number of noun syllables in verb-objection, we compare the dynamic neural mechanisms of the structure bisyllabic verb (V2)+monosyllabic noun (N1) (i.e. V2+N1) with V2+N1 (N2, bisyllabic noun). In Chinese, the rhythmic pattern V2+N1 is considered to be a metrical incongruity, whereas V2+N2 is considered to be a metrical congruity. For example, the verb yunshu (to transport) can be followed by liangshi (cereals). However, if yunshu is followed by liang (cereals), yunshu liang is usually considered to be metrically incongruous. This paper shows that (i) V2+N1 elicited more negative amplitudes than V2+N2 in the 90-170 ms and 450-500 ms windows, which indicates that metrical incongruities affect semantic processing in Chinese, and (ii) the acceptance rate for V2+N1 is significantly lower than that of V2+N2, which implies that metrical incongruities disrupt semantic processing in modern Chinese. These results are in agreement with previous studies. This is the first study to find that metrical incongruities disrupt semantic processing in Chinese. This study provides convergent evidence that metrical congruities facilitate semantic processing, whereas metrical incongruities disrupt semantic processing.
