通过 3 个实验探讨了耳间时间差 (ITD) 在知觉分组和选择性注意中的作用。实验 1 表明，在没有说话者或基频差异的情况下，听众可以利用 2 个句子之间 ITD 的微小差异来判断 2 个短的、恒定的目标词中哪一个是参与句子的一部分。实验 2 和 3 显示侦听器不会显式跟踪共享公共 ITD 的组件。他们无法通过 ITD 的差异从目标元音中分离出谐波：将元音放置在句子上下文中并没有实质性改变，其中句子与元音的其余部分共享相同的 ITD。结果表明，随着时间的推移，在跟随特定的听觉声源时，听众会关注特定方位角位置处的感知听觉对象，而不是明确关注共享公共 ITD 的那些频率分量。
The role of interaural time difference (ITD) in perceptual grouping and selective attention was explored in 3 experiments. Experiment 1 showed that listeners can use small differences in ITD between 2 sentences Co say which of 2 short, constant target words was part of the attended sentence, in the absence of talker or fundamental frequency differences. Experiments 2 and 3 showed that listeners do not explicitly track components that share a common ITD. Their inability to segregate a harmonic :From a target vowel by a difference in ITD was not substantially changed by the vowel being placed in a sentence context, where the sentence shared the same ITD as the rest of the vowel. The results indicate that in following a particular auditory sound source over time, listeners attend to perceived auditory objects at particular azimuthal positions rather than attend explicitly to those frequency components that share a common ITD.
