Abstract
In the accompanying article (B. W. A. Whittlesea & L. D. Williams, 2001), surprising violation of an expectation was observed to cause an illusion of familiarity. The authors interpreted that evidence as support for the discrepancy-attribution hypothesis. This article extended the scope of that hypothesis, investigating the consequences of surprising validation of expectations. Subjects were shown recognition probes as completions of sentence stems. Their expectations were manipulated by presenting predictive, nonpredictive, and inconsistent stems. Predictive stems caused an illusion of familiarity, but only when the subjects also experienced uncertainty about the outcome. That is, as predicted by the discrepancy-attribution hypothesis, feelings of familiarity occurred only when processing of a recognition target caused surprise. The article provides a discussion of the ways in which a perception of discrepancy can come about, as well as the origin and nature of unconscious expectations.Keywords
