Baumgartner and colleagues (this issue) report a replication of an ERP study by Kelly, Gomez-Ramirez, and Foxe (2008). Unlike the original authors, they failed to observe a significant modulation of the C1 by visuo-spatial attention. They conclude that initial afferent processing in V1 is impermeable to visuo-spatial attention. Although their study, like any replication effort, is valuable and important, there are some uncertainties at the methodological and statistical levels suggesting that the absence of evidence is not evidence of absence in the present case.
鲍姆加特纳及其同事（本期）报告了凯利、戈麦斯 - 拉米雷斯和福克斯（2008年）一项事件相关电位（ERP）研究的重复实验。与原作者不同的是，他们未能观察到视觉空间注意对C1的显著调制。他们得出结论，初级视觉皮层（V1）中的初始传入处理对视觉空间注意是不敏感的。尽管他们的研究与任何重复研究一样，有价值且重要，但在方法和统计层面存在一些不确定性，这表明在当前情况下，没有证据并不等同于证据不存在。
