The learned interpretation of cognitive fluency

The fluency of cognitive processes influences many judgments: Fluently processed statements are judged to be true, fluently processed instances are judged to be frequent, and fluently processed names are judged to be famous. According to a cue-learning approach, these effects of experienced fluency arise because the fluency cue is interpreted differentially in accordance with its learned validity. Two experiments tested this account by manipulating the fluency cue's validity. Fluency was manipulated by color contrast (Experiment 1) and by required mental rotation (Experiment 2). If low fluency was correlated with a required affirmative or "old" response (and high fluency with a negative or "new" response) in a training phase, participants showed a reversal of the classic pattern in the recognition phase: Low-fluency stimuli had a higher probability than high-fluency stimuli to be classified as old. Thus, the interpretation and therefore the impact of fluency depended on the cue's learned validity.
