Are selection history effects limited to implicit forms of memory? Evidence from intertrial repetition.

Selection history effects in visual attention are typically considered implicit memory effects. In three experiments, we investigated if a key selection history effect, intertrial priming, could be based on the incidental application of explicit memory. In the basic search task (Experiment 1), participants searched for real-world objects from different categories. We examined nonpredictive, intertrial repetition at two levels: (1) the repetition of target location from trial
