When two targets (T1 and T2) are embedded in a rapid serial visual presentation, T2 is often missed if it appears within 500ms after T1 (attentional blink, AB). However, a T2 report is not impaired if it immediately follows T1 (Lag-1 sparing). Furthermore, in a three-target AB paradigm, the third target is also easily identified when the targets are presented successively (Lag-2 sparing). The present study examined how targets were consolidated in working memory when Lag-2 sparing occurred, by observing the P3 component of the event-related potential. Multiple P3 components elicited separately by each target were observed when Lag-2 sparing occurred, suggesting that the trailing targets can be consolidated independently.
