Contextual Distinctiveness Produces Long-Lasting Priming of Pop-Out

Maljkovic and Nakayama have demonstrated memory influences in singleton search from one trial to the next, an effect they termed priming of pop-out (PoP). This effect was described as resulting from the persistence of an implicit memory trace, the influence of which could be observed for around 5-8 subsequent trials. Thomson and Milliken (2012) recently reported that PoP effects can survive a lag of up to 16 trials for "rare" trials that were …
