Abstract

Perceptual distraction distorts visual working memory representations. Previous research has shown that memory responses are systematically biased toward visual distractors that are similar to the memoranda. However, it remains unclear whether the prioritization of one working memory representation over another reduces the impact of perceptual distractors. In five behavioral experiments, we used different forms of retrospective cues (indicating the likelihood of testing each item and/or the reward for responding correctly to each item) to manipulate the prioritization of items in working memory before visual distraction. We examined the effects of distraction with nonparametric analyses and a novel distractor intrusion model. We found that memory responses were more precise (lower absolute response errors and stronger memory signals) for items that were prioritized. However, these prioritized items were not immune to distraction, and their memory responses were biased toward the visual distractors to the same degree as were unprioritized items. Our findings demonstrate that the benefits associated with prioritization in working memory do not include protection from distraction biases.
