Target familiarity and visual working memory do not influence familiarity effect in visual search

Abstract Familiarity effect refers to the phenomenon that searching for a novel target among familiar distractors is more efficient than that searching for a familiar target among novel distractors. While the familiarity of distractors is considered as a key role on familiarity effect, the familiari...
