Accounting for the strangeness, infrequency, and suddenness of déjà vu.

Barzykowski and Moulin argue that déjà vu is a natural product of autobiographical memory retrieval. Their proposal fails to account for three salient properties of déjà vu experiences: Their strangeness, their infrequency, and their characteristically sudden onset. Accounting for these properties is necessary for proper integration of déjà vu into autobiographical memory research.
