Deja vu is defined as high levels of familiarity for objects or situations that are objectively unfamiliar. One theory of deja vu is that objects viewed under conditions of divided perception can later evoke familiarity. The present study examined whether a change detection task could simulate divided perception and affect later recognition memory performance for changed items. Participants viewed a study list in which one version of a scene alternated once with another version of the same scene, but with one item missing. Participants attempted to determine the location of the change. On a subsequent test list, participants viewed items from the scenes in isolation and made recognition judgments on them. Across five experiments, this task was used to determine how detection status affected familiarity ratings, how stimulus characteristics affect familiarity ratings, and what recognition processes (i.e., recollection and familiarity) drive recognition decisions for undetected items. Overall, these experiments show that simulated conditions of divided perception do affect recognition memory, which is a first step towards investigating deja vu directly
