Traditional priming of pop-out (PoP) studies usually investigate how repeating a certain item subsequently facilitates its detection. The joint effects of repeating both an oddball target and distractors contribute to this facilitation. Those studies typically focus on reaction times (RTs). They can not determine the impact of priming on attentional selection because the target is generally predesignated. Recent studies have, therefore, explored the influence of priming on target choice using trials where observers freely select an item. Results from those experiments indicate that priming strongly influences target choice, highlighting its role in determining visual exploration. Selecting an item freely, conversely, induces typical pop-out RTs. These findings suggest that conventional PoP and choice trial priming share common mechanisms. Here, we sought to find more support for this overlap by independently repeating targets and distractors, which had always co-occurred in other choice experiments, and investigating their impact on choice. We intermixed six variations of pop-out trials (one oddball target among two identical distractors) with three variations of choice trials (two dissimilar targets) allowing us to separate target and distractor repetition. Both types of repetition biased subsequent choice. Our results, accordingly, support a relation between traditional priming and choice trial priming and are in line with PoP accounts focusing on relative salience of items in the environment.
