Integrating multiple cues in metamemory: using the illusory effect of font size and level of processing to inform FOK judgments

Abstract

Metamemory judgments, defined as predictions of memory performance, are often influenced by misleading cues, such as fluency. However, how fluency cues compete to influence retrospective metamemory judgments is still unclear. The present study investigated how multiple fluency cues concurrently influence immediate feeling of knowing (FOK) judgments with two fluency manipulations—font size (large vs. small font size) as a perceptual cue and level of processing (deep vs. shallow processing) as a conceptual cue. In Experiment 1, participants studied large or small unrelated word pairs and were either directed to process the conceptual aspects of each word pair (deep) or to focus on the perceptual aspects of the word pairs (shallow). Then participants were presented with a cued recall test and asked to make an FOK judgment. Lastly, participants received a five alternative- forced-choice recognition test. Experiment 2 was similar except the deep condition was replaced with a no-processing (no instruction) condition. Results revealed that perceptual fluency (large font size) influenced FOK judgments only when word pairs were processed in the shallow condition in both experiments compared to no-processing condition. This interaction of multiple cues suggests that, participants rely on information which is easily accessible to them (perceptual fluency) for FOK judgements in presence of certain secondary cues despite those cues being less diagnostic of future memory performance. These new insights inform how people integrate different sources of information in metamemory decisions and have broad implications for settings including academic learning and everyday decision making.
