两组实验研究了注意和单侧忽视对听觉流的影响。第一对实验表明，当正常参与者在对侧耳中处理竞争性任务时，他们的听觉流的建立会大大减少或消失。得出的结论是，流的有效建立取决于注意力。第二对研究表明，对左侧空间的注意力缺陷（单侧忽视）的患者表现出较少的流分离的音调序列呈现给他们的左耳比右耳。他们右耳的流类似于健康和脑损伤对照组的任何一只耳朵的刺激，没有显示出跨耳不对称。这一结果与注意力对流的影响是一致的，限制了所涉及的神经部位，并揭示了忽视患者对左侧和右侧声音的感知之间的质的差异。
Two pairs of experiments studied the effects of attention and of unilateral neglect on auditory streaming. The first pair showed that the build up of auditory streaming in normal participants is greatly reduced or absent when they attend to a competing task in the contralateral ear. It was concluded that the effective build up of streaming depends on attention. The second pair showed that patients with an attentional deficit toward the left side of space (unilateral neglect) show less stream segregation of tone sequences presented to their left than to their right ears. Streaming in their right ears was similar to that for stimuli presented to either ear of healthy and of brain-damaged controls, who showed no across-ear asymmetry. This result is consistent with an effect of attention on streaming, constrains the neural sites involved, and reveals a qualitative difference between the perception of left- and right-sided sounds by neglect patients.
