背景资料：知觉和电生理研究发现，老年人在安静和嘈杂环境中的言语辨别能力降低，神经计时延迟，神经同步性降低，时间处理能力下降，即使是听力正常的老年人也是如此。然而，最近的研究也表明，语言经验和听觉训练增强了听觉脑干反应（ABR）中声音编码的时间动力学。本研究旨在探讨具有声调语言背景的老年人在脑干水平上的音高加工能力。方法：本研究招募了讲普通话的年轻人（n = 12）和老年人（n = 12）。所有参与者的听力测试结果正常，阈上点击诱发ABR正常。为了记录普通话声调引起的频率跟随反应（frequencyfollowerresponses，FFR），在70dBSPL下，对两个基频不同的普通话音节（平调和降调）进行了研究。提取刺激和反应的基频（f0），并与个体脑干反应进行比较。本研究采用两个指标来考察脑干水平上音高加工能力的不同方面：音高强度和音高相关性。结果：与年轻成人组相比，老年人组的词汇音调引起的FFR总体较弱。通过音高强度和音高相关性的测量，只有当使用具有下降f0（下降音）的音调作为刺激时，才发现统计学上显著的组间差异。结论：这项研究的结果表明，在一个音调语言的人口，在脑干水平的老年人的音高处理能力是不强和强大的年轻同行。这项研究的结果是一致的，与以前的报告，其母语是英语的老年人的脑干反应。另一方面，词汇声调引起的FFR已被证明与语言暴露的长度相关。在我们的研究中，老年人的退化反应也可能是由于说普通话的老年人的长期暴露在一定程度上抵消了对衰老的负面影响，并有助于维持或至少降低脑干水平上的时间处理能力的退化率。
Background: Perceptual and electrophysiological studies have found reduced speech discrimination in quiet and noisy environment, delayed neural timing, decreased neural synchrony, and decreased temporal processing ability in elderlies, even those with normal hearing. However, recent studies have also demonstrated that language experience and auditory training enhance the temporal dynamics of sound encoding in the auditory brainstem response (ABR). The purpose of this study was to explore the pitch processing ability at the brainstem level in an aging population that has a tonal language background. Method: Mandarin speaking younger (n = 12) and older (n = 12) adults were recruited for this study. All participants had normal audiometric test results and normal suprathreshold click-evoked ABR. To record frequency following responses (FFRs) elicited by Mandarin lexical tones, two Mandarin Chinese syllables with different fundamental frequency pitch contours (Flat Tone and Falling Tone) were presented at 70 dB SPL. Fundamental frequencies (f0) of both the stimulus and the responses were extracted and compared to individual brainstem responses. Two indices were used to examine different aspects of pitch processing ability at the brainstem level: Pitch Strength and Pitch Correlation. Results: Lexical tone elicited FFR were overall weaker in the older adult group compared to their younger adult counterpart. Measured by Pitch Strength and Pitch Correlation, statistically significant group differences were only found when the tone with a falling f0 (Falling Tone) were used as the stimulus. Conclusion: Results of this study demonstrated that in a tonal language speaking population, pitch processing ability at the brainstem level of older adults are not as strong and robust as their younger counterparts. Findings of this study are consistent with previous reports on brainstem responses of older adults whose native language is English. On the other hand, lexical tone elicited FFRs have been shown to correlate with the length of language exposure. Older adults’ degraded responses in our study may also be due to that, the Mandarin speaking older adults’ long term exposure somewhat counteracted the negative impact on aging and helped maintain, or at least reduced, the degradation rate in their temporal processing capacity at the brainstem level.
