母语声调语言体验与语言中音高的产生和感知的变化以及大脑对语言和非语言声调的反应有关。在这里，我们使用两个实验来解决这些变化是否适用于简单的音高变化和音高间隔的歧视。本研究采用事件相关电位（ERP）技术，分别记录了汉语母语者和对照组在相同/不同任务中纯音对的音高差异和纯音对的音程差异。在行为上，普通话说话者在检测音高和间隔变化方面比对照组更准确，对控制组中不存在的小音高变化和间隔距离表现出敏感性。在相同的任务中获得的ERP收敛的证据显示，在普通话讲者的变化相对于无变化的试验，以及早期分化的试验相对于控制的变化方向的反应。这些发现说明了跨域的影响，语言经验的感知音高，这表明，母语使用的音调音高轮廓在语言中导致的音高表征的敏锐度普遍增强。
Native tone language experience has been linked with alterations in the production and perception of pitch in language, as well as with the brain response to linguistic and non-linguistic tones. Here we use two experiments to address whether these changes apply to the discrimination of simple pitch changes and pitch intervals. Event related potentials (ERPs) were recorded from native Mandarin speakers and a control group during a same/different task with pairs of pure tones differing only in pitch height, and with pure tone pairs differing only in interval distance. Behaviorally, Mandarin speakers were more accurate than controls at detecting both pitch and interval changes, showing a sensitivity to small pitch changes and interval distances that was absent in the control group. Converging evidence from ERPs obtained during the same tasks revealed an earlier response to change relative to no-change trials in Mandarin speakers, as well as earlier differentiation of trials by change direction relative to controls. These findings illustrate the cross-domain influence of language experience on the perception of pitch, suggesting that the native use of tonal pitch contours in language leads to a general enhancement in the acuity of pitch representations.
