为了研究眼跳准备是否可以调节听觉刺激的处理在空间上特定的方式，ERPs记录眼跳任务，其中准备眼跳的方向是线索，之前的命令性听觉刺激，指示是否执行或保留眼跳。为了比较，我们还运行了一个传统的内隐注意任务，其中相同的线索，现在指出了方向的内隐内源性注意力转移之前的听觉目标-非目标歧视。偏侧化组件先前观察到的线索转移的注意力（ADAN，LDAP）没有显着不同的任务，表明听觉空间注意力和视觉控制之间的共性。此外，在这两项任务中，随后发现了听觉处理的空间特定调制，在有线索与无线索的位置处，侧向听觉非目标刺激的负性增强。这种调制开始较早，更明显的内隐注意任务，但也可靠地存在于眼跳任务，表明对听觉处理的内隐眼跳准备的效果可以类似于内源性内隐注意定向的效果，虽然较小。这些发现提供了新的证据的相似性，但也有一些差异眼准备和内源性空间注意的转移。他们还表明，眼跳准备不仅会影响视觉，还会影响听觉事件的感觉处理。
To investigate whether saccade preparation can modulate processing of auditory stimuli in a spatially-specific fashion, ERPs were recorded for a Saccade task, in which the direction of a prepared saccade was cued, prior to an imperative auditory stimulus indicating whether to execute or withhold that saccade. For comparison, we also ran a conventional Covert Attention task, where the same cue now indicated the direction for a covert endogenous attentional shift prior to an auditory target-nontarget discrimination. Lateralised components previously observed during cued shifts of attention (ADAN, LDAP) did not differ significantly across tasks, indicating commonalities between auditory spatial attention and oculomotor control. Moreover, in both tasks, spatially-specific modulation of auditory processing was subsequently found, with enhanced negativity for lateral auditory nontarget stimuli at cued versus uncued locations. This modulation started earlier and was more pronounced for the Covert Attention task, but was also reliably present in the Saccade task, demonstrating that the effects of covert saccade preparation on auditory processing can be similar to effects of endogenous covert attentional orienting, albeit smaller. These findings provide new evidence for similarities but also some differences between oculomotor preparation and shifts of endogenous spatial attention. They also show that saccade preparation can affect not just vision, but also sensory processing of auditory events.
