This article provides data from statistical analysis of event-related brain potentials (ERPs) and behavioural performance from 23 participants during a working memory task. Specifically, we used the change detection task from Vogel 2004, using the same timing but a modified size and distance between stimuli. Contralateral delay activity (CDA) was calculated from posterior parieto-occipital electrodes and then it was compared between conditions with different memory load (one, two and four items). Working memory capacity (WMC) was calculated from behavioural data using the formula developed by Pashler (1988). Correlation was performed between WMC and the CDA amplitude difference (from two to four items). The correlation replicates the results from the original paper of Vogel 2004 [1], even though some parameters are different from the original design.
本文提供了23名参与者在工作记忆任务期间与事件相关的脑电位（ERP）统计分析数据以及行为表现数据。具体而言，我们采用了Vogel 2004年的变化检测任务，使用相同的时间安排，但修改了刺激之间的大小和距离。从顶枕后部电极计算对侧延迟活动（CDA），然后在不同记忆负荷（一项、两项和四项）的条件之间进行比较。使用Pashler（1988）开发的公式从行为数据计算工作记忆容量（WMC）。对WMC与CDA幅度差异（从两项到四项）进行了相关性分析。尽管一些参数与原始设计不同，但该相关性重复了Vogel 2004年原始论文的结果[1]。
