Early Sino-Vietnamese Lexical Data and the Relative Chronology of Tonogenesis in Chinese and Vietnamese

Vietnamese has numerous early-era Chinese loanwords with ngang and huyền tones, which in Middle Chinese loanwords correspond to the pingsheng level tone category, for words that should have sắc or nặng tones, corresponding to the Middle Chinese non-level qusheng departing tone category. 1 It is proposed that this layer of Early Sino-Vietnamese represents borrowing of Chinese words in the period after which Old Chinese had lost final *-s and prior to tonogenesis in Viet-Muong, thus leading to words with the level-tone category when tones emerged in Viet-Muong. This paper provides 60 items of Early Sino-Vietnamese that exemplify this phenomenon of ngang/huyền tones in qusheng words, but also 120 items exemplifying the previously noted reversal of sắc/nặng and hỏi/ngã tones between Early Sino-Vietnamese and later Sino-Vietnamese (the formalized readings of Chinese characters). Altogether, this allows for an overall relative chronology of the development of tones in both Sinitic and Vietic.

Absolute Pitch: Evidence for Early Cognitive Facilitation during Passive Listening as Revealed by Reduced P3a Amplitudes

Absolute pitch (AP) is the rare ability to identify or produce different pitches without using reference tones. At least two sequential processing stages are assumed to contribute to this phenomenon. The first recruits a pitch memory mechanism at an early stage of auditory processing, whereas the second is driven by a later cognitive mechanism (pitch labeling). Several investigations have used active tasks, but it is unclear how these two mechanisms contribute to AP during passive listening. The present work investigated the temporal dynamics of tone processing in AP and non-AP (NAP) participants by using EEG. We applied a passive oddball paradigm with between- and within-tone category manipulations and analyzed the MMN reflecting the early stage of auditory processing and the P3a response reflecting the later cognitive mechanism during the second processing stage. Results did not reveal between-group differences in MMN waveforms. By contrast, the P3a response was specifically associated with AP and sensitive to the processing of different pitch types. Specifically, AP participants exhibited smaller P3a amplitudes, especially in between-tone category conditions, and P3a responses correlated significantly with the age of commencement of musical training, suggesting an influence of early musical exposure on AP. Our results reinforce the current opinion that the representation of pitches at the processing level of the auditory-related cortex is comparable among AP and NAP participants, whereas the later processing stage is critical for AP. Results are interpreted as reflecting cognitive facilitation in AP participants, possibly driven by the availability of multiple codes for tones.
