A same-different task was used to test the hypothesis that musical expertise improves the discrimination of tonal and segmental (consonant, vowel) variations in a tone language, Mandarin Chinese. Two four-word sequences (prime and target) were presented to French musicians and nonmusicians unfamiliar with Mandarin, and event-related brain potentials were recorded. Musicians detected both tonal and segmental variations more accurately than nonmusicians. Moreover, tonal variations were associated with higher error rate than segmental variations and elicited an increased N2/N3 component that developed 100 msec earlier in musicians than in nonmusicians. Finally, musicians also showed enhanced P3b components to both tonal and segmental variations. These results clearly show that musical expertise influenced the perceptual processing as well as the categorization of linguistic contrasts in a foreign language. They show positive music-to-language transfer effects and open new perspectives for the learning of tone languages.
Previous research shows that music ability provides positive effects on language processing. This study aims at better clarifying the involvement of different linguistic subdomains in this cross-domain link, assessing whether or not musicality and music expertise enhance phonological and lexical tone processing of Mandarin Chinese. In two experiments different groups of adults and children with no previous experience in tonal languages, were invited to perform a same-different task trying to detect phonological and tonal variations in pairs of sequences of monosyllabic Mandarin Chinese words. Main results show that all subjects perform significantly better in detecting phonological variations rather than tonal ones. They also show that both melodic proficiency and music expertise are good predictors for a better tonal, but not phonological identification. Data lead to a model of music-to-language transfer effect in which musicality selectively affects linguistic intonation while leaving phonological processing substantially unaffected
In tonal languages, as Mandarin Chinese and Thai, word meaning is partially determined by lexical tones. Previous studies suggest that lexical tones are processed by native listeners as linguistic information and not as pure tonal information. This study aims at verifying if, in nontonal languages speakers, the discrimination of lexical Mandarin tones varies in function of the melodic ability. Forty-six students with no previous experience of Mandarin or any other tonal language were presented with two short lists of spoken monosyllabic Mandarin words and invited to perform a same-different task trying to identify whether the variation were phonological or tonal. Main results show that subjects perform significantly better in identifying phonological variations rather than tonal ones and interestingly, the group with a high melodic ability (assessed by Wing subtest 3) shows a better performance exclusively in detecting tonal variations.
