Lateralized ERP components triggered during cued shifts of spatial attention (anterior directing attention negativity [ADAN], late directing attention positivity [LDAP]) have been observed during visual, auditory, and tactile attention tasks, suggesting that these components reflect supramodal attentional control processes. This interpretation has recently been called into question by the finding that the ADAN is absent in response to auditory attention cues. Here we demonstrate that ADAN and LDAP components are reliably elicited in a purely unimodal auditory attention task where auditory cues are followed by auditory imperative stimuli. The fact that the ADAN is not restricted to task contexts where visual or tactile stimuli are relevant is consistent with the hypothesis that this component is linked to supramodal attentional control.
在空间注意的线索化转移过程中触发的偏侧化事件相关电位成分（前向注意负波[ADAN]、后向注意正波[LDAP]）已在视觉、听觉和触觉注意任务中被观察到，这表明这些成分反映了超模态注意控制过程。最近，由于发现对听觉注意线索的反应中不存在ADAN，这一解释受到了质疑。在此，我们证明，在一个纯粹单模态的听觉注意任务中，当听觉线索后接听觉指令刺激时，ADAN和LDAP成分能可靠地诱发。ADAN并不局限于与视觉或触觉刺激相关的任务情境，这一事实与该成分与超模态注意控制相关的假设是一致的。
