本研究探讨了外源性空间注意对听觉信息加工的影响。在实验1、2和3中，进行了时间顺序判断任务，以检查效果。在实验1和2中，提示音被呈现给左耳或右耳，然后依次呈现两个目标音。受试者判断目标音调的呈现顺序。结果表明，当目标音出现在与提示音同侧的目标音出现在对侧的目标音之后时，被试同时听到两个音。这表明提示音引起了空间外源性注意，并促进了随后的听觉信息加工。实验3考察了提示位置和提示频率是否影响信息加工。观察到了同样的空间注意效应，但只观察到了对某一频率的注意效应。实验四采用声调融合判断任务考察空间注意效应是否发生在听觉的初始阶段。结果表明，这种效应发生在听力的后期。
This study investigated the effect of exogenous spatial attention on auditory information processing. In Experiments 1, 2 and 3, temporal order judgment tasks were performed to examine the effect. In Experiment 1 and 2, a cue tone was presented to either the left or right ear, followed by sequential presentation of two target tones. The subjects judged the order of presentation of the target tones. The results showed that subjects heard both tones simultaneously when the target tone, which was presented on the same side as the cue tone, was presented after the target tone on the opposite side. This indicates that spatial exogenous attention was aroused by the cue tone, and facilitated subsequent auditory information processing. Experiment 3 examined whether both cue position and frequency influence the resulting information processing. The same effect of spatial attention was observed, but the effect of attention to a certain frequency was only partially observed. In Experiment 4, a tone fusion judgment task was performed to examine whether the effect of spatial attention occurred in the initial stages of hearing. The result suggests that the effect occurred in the later stages of hearing.
