听觉空间注意是通过操纵听觉空间线索与听觉目标之间的时空关系来研究的。主要发现是，随着将注意力转移到提示空间位置的可用时间的增加，表现会有所提高；准确的空间线索比不准确的线索更能促进表现；在0度和180度的注意力转移范围内，表现几乎相同；实验提供的证据表明，听觉注意力可能会被分配到一个特定的位置，以响应听觉空间线索，而转移注意力所需的时间似乎并不取决于转移的距离。此外，研究结果表明，听觉注意的空间分布可以用梯度模型最准确地描述，在梯度模型中，注意力资源随着与焦点的距离逐渐下降。
Auditory spatial attention was investigated by manipulating spatial and temporal relations between an auditory spatial cue and an auditory target. The principal findings were that performance improved as time available to shift attention to a cued spatial position increased, accurate spatial cues facilitated performance more than inaccurate cues, performance was virtually identical for shifts of attention ranging from 0 degrees and 180 degrees, and performance declined as the distance of an unexpected target from a cued spatial location increased. The experiments provided evidence that auditory attention may be allocated to a specific location in response to an auditory spatial cue and that the time required to shift attention does not appear to depend on the distance of the shift. Furthermore, the findings suggest that the spatial distribution of auditory attention may be described most accurately by a gradient model in which attentional resources decline gradually with distance from a focal point.
