Change in perceptual form attenuates the use of the fluency heuristic in recognition

Abstract

Four experiments (total N = 295) were conducted to determine whether within-modality changes in perceptual form between the study and the test phases of an experiment would moderate the role of the fluency heuristic in recognition memory. Experiment 1 showed that a change from pictures to words reduced the role of fluency in recognition memory. In Experiment 2, the same result was found using counterfeit study lists that supposedly consisted of pictures or words. Experiments 3 and 4 showed that changes in the font used to present the study and test words also attenuated the contribution of fluency to the recognition decision when font change was manipulated between subjects, but not within subjects. Results suggest that the fluency heuristic is subject to metacognitive control, since participants' attributions of perceptual fluency depend on the perceived usefulness of fluency as a cue to recognition.
