Abstract:
Recent studies found that the lexical tone processing in Mandarin Chinese was normal for amusics with musical perception disorders, but was degraded for a subgroup of amusics, named tone agnosics. The current study aimed to further explore whether the lexical deficits in tone agnosics were presented in phonetic processing, in particular, diphthong and triphthong. Vowel and tone identifications were examined among three groups of Mandarin-native listeners: tone agnosics (amusics with lexical tone deficits), the pure amusics (with normal lexical processing) and normal controls. Preliminary results showed that tone agnosics had the lowest scores in the identification of vowel-plus-tones, vowels, and tones, while the performances were similar between the pure amusics and normal controls. Moreover, tone agnosics showed deficits not only in lexical tone identification, but also in vowel identification. Particularly, the disadvantages of tone agnosics in both vowel and tone processing appeared to be greater in diphthongs and triphthongs than in monothongs. Speech processing of pure amusics was comparable with that of the control group, although they had deficits in musical disorders, implying that musical perception was separate from speech perception at high-level processing. On the other hand, tone agnosia had deficits in both musical and speech processing.
