在一系列实验中，我们研究了听觉注意力是否会像最近报道的视觉注意力一样，朝着即将到来的扫视方向转移。正常的听者对突然声音的提升（上升或下降）进行了速度区分，而不考虑它们的横向性。每一种声音都是在进行横向扫视的同时出现的。当扫视朝向听觉探针的一侧而不是远离时，听觉的高度辨别确实更快。此外，一侧的听觉探针加速了该方向的中央线索扫视，尽管声音对周边视觉事件的扫视没有影响。后一种视觉事件不足以影响听觉，除非对其进行扫视。一项进一步的研究表明，注视声音或远离声音，而不是扫视，也会影响高度判断，当注视别处时，表现更差。然而，即将到来的扫视对听力的影响不能归结为这种注视效应，因为即使在注视开始转变之前停止的声音也会产生扫视影响。综上所述，我们的结果表明，即将到来的扫视的方向会影响听力，就像眼睛的位置一样。1999爱思唯尔科学有限公司版权所有。
In a series of experiments, we examined whether auditory attention shifts in the direction of an upcoming saccade, as recently reported for visual attention. Normal listeners made speeded discriminations for the elevation (up versus down) of abrupt sounds, regardless of their laterality. Each sound was presented around the time that a lateral saccade was made. Auditory elevation discriminations were reliably faster when the saccade was made towards the side of the auditory probe rather than away. Furthermore, an auditory probe on one side speeded up centrally-cued saccades made in that direction, although sounds did not influence saccades to peripheral visual events. The latter visual events were insufficient to affect hearing unless a saccade was made towards them. A further study showed that fixating towards or away from sounds, rather than saccading, could also affect elevation judgements, with poorer performance when fixating away. However, the influence of an upcoming saccade upon hearing could not be reduced to this fixation effect, since the saccade influence was found even for sounds which terminated before any shift in fixation began. Taken together, our results imply that the direction of an upcoming saccade can affect hearing, as can eye-position. (C) 1999 Elsevier Science Ltd. All rights reserved.
