Resolving the apparent discrepancy between the incongruency effect and the expectancy-based illusory correlation effect: the TRAP model.
The incongruency effect and the expectancy-based illusory correlation effect seem contradictory because they describe apparently contrasting consequences of previously held expectancies: better recall of incongruent than congruent items but overestimation of congruent items. This article resolves this dilemma by presenting a model that is able to simultaneously predict both of these effects. The Twofold Retrieval by Associative Pathways (TRAP) model adopts the encoding assumptions of person memory models but distinguishes between two different retrieval processes, exhaustive and heuristic, hypothesized to underlie recall and frequency estimation, respectively. Experiment 1 showed that expectancy-based illusory correlation effects and incongruency effects are compatible in that they were produced simultaneously. Experiments 2 and 3 tested and rejected alternative explanations for the obtained pattern of results.
