声调范畴感知和声调复杂度对音乐音高感知的跨领域影响

The cross-domain influence of tonal categorical perception and tonal complexity on musical pitch perception

采用音高识别与区分任务,以汉语母语者、越南语母语者和俄语母语者为研究对象,考察了两个语言加工层面的因素,即声调范畴感知模式以及不同语言声调系统的复杂度差异对跨领域音乐音高感知的影响。结果发现:(1)汉语和越南语两组声调语言母语者听辨结果符合范畴感知模式,而俄语母语者是连续感知。在语言和音乐两种刺激条件下,声调语言母语者在范畴边界宽度、范畴内区分率、范畴间区分率以及区分峰度等指标上不存在显著差异。(2)汉语和越南语两组声调语言母语者的音乐音高区分任务结果差异不显著。实验结果表明:在行为层面,母语声调范畴感知模式可以迁移到音乐音高感知中,但复杂声调系统并不能促进跨领域的音乐音高精细感知。实验结果从语言对音乐音高加工影响的角度支持了“共享论”。

Pitch is a fundamental acoustic property shared by both language and music.However,there are different views on the processing of tonal pitch and musical pitch.Some studies support the“modularity view”,suggesting that tonal pitch and musical pitch are represented separately.In contrast,more studies support the“shared domain-general view”,implying that there are commonalities in the processing of tonal pitch and musical pitch based on their physical similarities.The existing studies have mostly focused on domain-general pitch transfer;nonetheless,they have not considered domain specificity of the tonal pitch as a linguistic element.Hence,it remains unclear whether domain specificity factors,such as categorical perception and complexity of different tonal language experiences on speakers’pitch processing,play a role in musical pitch perception.To address the above issues,ninety participants were involved in the experiment,including native speakers of Mandarin Chinese(with a relatively simple pitch category),native speakers of Vietnamese(with a relatively complex pitch category),and native speakers of Russian(nonpitched control group).A 3(group:Vietnamese vs.Chinese vs.Russian)×2(stimulus type:speech vs.music)between-and-within-subjects design was used.A continuum from[i˥](closed for Yinping in Chinese and Transverse in Vietnamese)to[i˧˥](closed for Yangping in Chinese and Acute in Vietnamese)and its musical counterpart was constructed.Participants were first tested in an ABX identification task to determine whether the stimulus X was similar to A or B and then an AX discrimination task to decide whether the two stimuli in the pair were identical.The experiment was performed in E-prime 3.0.The results showed that(1)both the Chinese and Vietnamese groups showed categorical perception for language and music pitches.There were no differences between language and music stimuli in category boundary width,within-category discrimination rate,between-category discrimination rate,or discrimination peak for either group.The Russian group’s identification curve did not show abrupt shifts,and their discrimination curve was relatively flat with multiple peaks,which indicates a continuous pattern significantly different from the two tonal language groups.(2)There were no significant differences between the Vietnamese group and the Chinese group in either the within-category discrimination rate or the between-category discrimination rate.The experimental results suggest that at the behavioral level,the pattern of native tonal categorical perception can transfer to musical pitch perception,but tonal complexity does not facilitate cross-domain musical pitch perception.The findings of this study support the“shared domain-general view”in terms of the influence of language on musical pitch processing.
