Carlyon等人（2001年实验心理学杂志：人类感知和表现27 115 - 127）报告说，当注意力被转移到竞争性听觉刺激时，听觉流的积累会减少。在这里，我们证明了流的减少也可以通过关注视觉任务或要求以三为单位向后计数来获得。在所有条件下，参与者都听到了13秒的音调序列，并且在前10秒看到了包含三个，四个或五个目标的视觉刺激序列。音调序列由20个重复的三连音组成。顺序，其中A和B代表两个不同频率的音调。在每个序列中，三个、四个或五个音调被调幅。在序列的前10秒，参与者要么计算视觉目标的数量，要么计算（调节的）听觉目标的数量，或者从指定的数字开始以3为单位倒数。然后，他们对音调序列的最后30秒进行了听觉流判断：是听到了一个还是两个流。结果显示，与“视觉”或“倒数”相比，参与者在计算听觉目标时（因此在整个过程中都在关注音调）流的信息更多。
Carlyon et al (2001 Journal of Experimental Psychology: Human Perception and Performance 27 115 - 127) have reported that the buildup of auditory streaming is reduced when attention is diverted to a competing auditory stimulus. Here, we demonstrate that a reduction in streaming can also be obtained by attention to a visual task or by the requirement to count backwards in threes. In all conditions participants heard a 13 s sequence of tones, and, during the first 10 s saw a sequence of visual stimuli containing three, four, or five targets. The tone sequence consisted of twenty repeating triplets in an ABA-ABA... order, where A and B represent tones of two different frequencies. In each sequence, three, four, or five tones were amplitude modulated. During the first 10 s of the sequence, participants either counted the number of visual targets, counted the number of (modulated) auditory targets, or counted backwards in threes from a specified number. They then made an auditory-streaming judgment about the last 3 s of the tone sequence: whether one or two streams were heard. The results showed more streaming when participants counted the auditory targets (and hence were attending to the tones throughout) than in either the 'visual' or 'counting-backwards' conditions.
