Why do strangers feel familiar, but friends don't? A discrepancy-attribution account of feelings of familiarity

It is argued that it is not fluency per se, but rather fluent processing occurring under unexpected circumstances that produces the feeling of familiarity, and cases in which moderately fluent processing produces more familiarity than does highly fluent processing, at least when the former is surprising.

Abstract

Recent articles on familiarity (e.g. Whittlesea, B.W.A, 1993. Journal of Experimental Psychology 19, 1235) have argued that the feeling of familiarity is produced by unconscious attribution of fluent processing to a source in the past. In this article, we refine that notion: We argue that is not fluency per se, but rather fluent processing occurring under unexpected circumstances that produces the feeling. We demonstrate cases in which moderately fluent processing produces more familiarity than does highly fluent processing, at least when the former is surprising.
