论文摘要
视觉工作记忆（VWM）使我们能够积极存储，更新和操纵周围的视觉信息。虽然VWM的潜在神经机制尚不清楚，但对侧延迟活动（CDA），与要记住的视觉物品位置对侧的半球相对于半球的持续负效率，通常用于研究VWM。为了调查CDA是否是VWM任务的鲁棒神经相关性，我们通过公开访问的EEG数据集重现了八项与CDA相关的研究。我们使用了这项八项研究中的原始脑电图数据，并使用相同的基本管道分析了所有研究以提取CDA。我们能够从所有研究中重现结果，并表明，使用基本的自动EEG管道，我们可以提取清晰的CDA信号。我们分享了整个研究中观察到的趋势的见解，并在召回阶段提出了有关CDA衰减和CDA的一些问题，令人惊讶的是，这八项研究都没有解决。最后，我们还根据我们的经验和重现这些研究的挑战提供了可重复性建议。
Visual working memory (VWM) allows us to actively store, update and manipulate visual information surrounding us. While the underlying neural mechanisms of VWM remain unclear, contralateral delay activity (CDA), a sustained negativity over the hemisphere contralateral to the positions of visual items to be remembered, is often used to study VWM. To investigate if the CDA is a robust neural correlate for VWM tasks, we reproduced eight CDA-related studies with a publicly accessible EEG dataset. We used the raw EEG data from these eight studies and analyzed all of them with the same basic pipeline to extract CDA. We were able to reproduce the results from all the studies and show that with a basic automated EEG pipeline we can extract a clear CDA signal. We share insights from the trends observed across the studies and raise some questions about the CDA decay and the CDA during the recall phase, which surprisingly, none of the eight studies did address. Finally, we also provide reproducibility recommendations based on our experience and challenges in reproducing these studies.
