通过一个时间延迟检测任务，研究了人工耳蜗（CI）听者的顺序流分离，该任务由在单个电极(B)上呈现的一系列规则脉冲爆发与在不同电极上呈现的不规则序列(a)交织而成。在一半的实验中，在常规B序列的最后一次爆发中增加了延迟，并要求听众察觉到这种延迟。由于在连续a脉冲之间添加了抖动，a和B序列之间的时间判断提供了执行任务的不可靠线索。因此，A和B序列的分离应该会提高性能。在实验1中，改变电极分离和序列持续时间，以阐明位置线索是否有助于CI听者自愿分离声音，以及两流感知是否需要时间来建立。结果表明，如果提供足够的时间来建立两流感知，位置线索可以促进顺序声音的分离。在实验2中，序列的持续时间是固定的，只改变电极的分离来估计裂变边界。大多数听者能够区分三个或更多电极之间的声音，一些听者能够区分来自相邻电极的声音。
Sequential stream segregation by cochlear implant (CI) listeners was investigated using a temporal delay detection task composed of a sequence of regularly presented bursts of pulses on a single electrode (B) interleaved with an irregular sequence (A) presented on a different electrode. In half of the trials, a delay was added to the last burst of the regular B sequence, and the listeners were asked to detect this delay. As a jitter was added to the period between consecutive A bursts, time judgments between the A and B sequences provided an unreliable cue to perform the task. Thus, the segregation of the A and B sequences should improve performance. In Experiment 1, the electrode separation and the sequence duration were varied to clarify whether place cues help CI listeners to voluntarily segregate sounds and whether a two-stream percept needs time to build up. Results suggested that place cues can facilitate the segregation of sequential sounds if enough time is provided to build up a two-stream percept. In Experiment 2, the duration of the sequence was fixed, and only the electrode separation was varied to estimate the fission boundary. Most listeners were able to segregate the sounds for separations of three or more electrodes, and some listeners could segregate sounds coming from adjacent electrodes.
