了解个体差异在工作记忆容量（WMC）中的作用很重要。我们研究了WMC和N1事件相关脑电位的差异之间的关系，作为衡量早期选择性注意的听觉干扰在三刺激古怪的任务，需要最小的内存。高WMC组（n=13）表现出较小的N1在一个分心物和目标比低WMC组（n=13）在新的条件下，高分心。而在低牵张的简单条件下，两组N1无差异。对于所有的参与者（n=52），WMC和N1峰振幅的分数之间的相关性是强的分心物在新的条件下，而在简单的条件下没有关系。这些结果表明，即使在选择性注意任务中，WMC也可以预测听觉门控时显著干扰物的干扰控制。
It is important to understand the role of individual differences in working memory capacity (WMC). We investigated the relation between differences in WMC and N1 in event-related brain potentials as a measure of early selective attention for an auditory distractor in three-stimulus oddball tasks that required minimum memory. A high-WMC group (n=13) showed a smaller N1 in response to a distractor and target than did a low-WMC group (n=13) in the novel condition with high distraction. However, in the simple condition with low distraction, there was no difference in N1 between the groups. For all participants (n=52), the correlation between the scores for WMC and N1 peak amplitude was strong for distractors in the novel condition, whereas there was no relation in the simple condition. These results suggest that WMC can predict the interference control for a salient distractor at auditory gating even during a selective attention task.
