Simultaneous utilization of multiple cues in judgments of learning.

There is much evidence that metacognitive judgments, such as people's predictions of their future memory performance (judgments of learning, JOLs), are inferences based on cues and heuristics. However, relatively little is known about whether and when people integrate multiple cues in one metacognitive judgment or focus on a single cue without integrating further information. The current set of experiments systematically addressed whether and to what degree people integrate multiple extrinsic and intrinsic cues in JOLs. Experiment 1 varied two cues: number of study presentations (1 vs. 2) and font size (18 point vs. 48 point). Results revealed that people integrated both cues in their JOLs. Experiment 2 demonstrated that the two word characteristics concreteness (abstract vs. concrete) and emotionality (neutral vs. emotional) were integrated in JOLs. Experiment 3 showed that people integrated all four cues in their JOLs when manipulated simultaneously. Finally, Experiment 4 confirmed integration of three cues that varied on a continuum rather than in two easily distinguishable levels. These results demonstrate that people have a remarkable capacity to integrate multiple cues in metacognitive judgments. In addition, our findings render an explanation of cue effects on JOLs in terms of demand characteristics implausible.
