Event-related potentials (ERPs) elicited by self-induced sounds are often smaller than ERPs elicited by identical, but externally generated sounds. This action-related auditory ERP attenuation is more pronounced when self-induced sounds are intermixed with similar sounds generated by an external source. The current study explored whether attentional factors contributed to this phenomenon. Participants performed tone-eliciting actions, while the action-tone contingency and the set of additional action effects (tactile only, tactile and visual) were manipulated in a blocked manner. Previous action-tone contingence-effects were replicated, but the addition of other sensory action consequences did not influence the magnitude of auditory ERP attenuation. This suggests that the amount of attention allocated to concurrent non-auditory action effects does not substantially affect the magnitude of action-related auditory ERP attenuation and is on a par with the assumption that action-related auditory ERP attenuation might be related to the process of distinguishing self-induced stimuli from externally generated ones.

由自我感应的声音引起的事件相关电位（ERP）通常小于由相同但外部产生的声音引起的事件相关电位。当自我感应的声音与外部来源产生的相似声音混合时，这种与动作有关的听觉ERP衰减会更加明显。当前的研究探讨了注意因素是否导致了这种现象。参与者执行了调音动作，同时以阻塞的方式操纵了音调偶然性和其他动作效果集（仅触觉，触觉和视觉）。复制了以前的动作音素连贯效应，但是增加了其他感觉动作后果并没有影响听觉ERP衰减的程度。
