本研究调查了听力正常成年人与持续耳间时差（ITD）辨别训练（即重复练习）相关的学习情况。具体来说，这项研究解决了先前研究结论中的一个明显差异，这些研究报告了高频率而不是低频率的训练诱导学习。20名听力正常的成年人接受了低频或高频刺激的训练，与可比的渐近阈值相关，或作为未经训练的对照。总的来说，经过训练的听众在多个会话中学到的东西比对照组多。低频和高频刺激的学习幅度和时间过程是相似的。虽然这与先前低频ITD研究的结论不一致，但报告的结果可能无法证明先前的结论。泛化的学习频率，虽然更详细的调查刺激特定的学习是必要的。总的来说，结果是一致的概念，即正在进行的ITD处理是跨频率的功能统一。这些结果可能对临床人群有影响，例如双侧人工耳蜗植入者。
This study investigated learning, in normal-hearing adults, associated with training (i.e. repeated practice) on the discrimination of ongoing interaural time difference (ITD). Specifically, the study addressed an apparent disparity in the conclusions of previous studies, which reported training-induced learning at high frequencies but not at low frequencies. Twenty normal-hearing adults were trained with either low- or high-frequency stimuli, associated with comparable asymptotic thresholds, or served as untrained controls. Overall, trained listeners learnt more than controls and over multiple sessions. The magnitudes and time-courses of learning with the low- and high-frequency stimuli were similar. While this is inconsistent with the conclusion of a previous study with low-frequency ITD, this previous conclusion may not be justified by the results reported. Generalization of learning across frequency was found, although more detailed investigations of stimulus-specific learning are warranted. Overall, the results are consistent with the notion that ongoing ITD processing is functionally uniform across frequency. These results may have implications for clinical populations, such as users of bilateral cochlear implants.
