22: Metacognitive Illusions in Auditory Information: Effects on Monitoring and Control

Metacognitive Illusions in Auditory Information: Effects on Monitoring and Control

Rhodes & Castel, 2009

Judgments of Learning (JOLs)

  • JOLs are subjective assessments individuals make regarding how well they have learned information.

  • Notable discrepancies exist between the cues used to make JOLs and the actual effects those cues have on memory.

  • Understanding these discrepancies helps uncover the role of perceptual quality in JOLs and recall.

Key Concepts

  • Retrieval Fluency (Benjamin et al. 1998)

    • Refers to the ease with which information can be accessed from memory.

    • It is hypothesized that perceptual fluency enhances the likelihood of reporting information as studied.

Experiments Overview

Experiment 1

  • Focused on the influence of font size on JOLs.

Experiment 2

  • Investigated the effects of test experience on JOLs.

Experiment 3

  • Examined the impact of salient (valid) cues on JOLs.

Experiment 4

  • Studied the effect of explicit warnings on JOLs.

Experiment 5

  • Analyzed judgments of forgetting and their relation to JOLs.

Experiment 6

  • Disrupted fluency to better understand its effects on JOLs.

Font Size Effect (Rhodes & Castel, 2008)

  • Larger font words receive higher JOLs than smaller font words even though there is no difference in recall based on font size.

  • Implications suggest that allocating study time should depend on perceived difficulty rather than actual recall ability.

  • Raises the question of whether the relative loudness of information can influence recall and JOLs, and how loudness may affect study time allocation.

Experiment 1: Loudness Effect

  1. Participants listened to four sample words to calibrate volume.

  2. They were informed that words would be presented at different volumes and were given JOL instructions.

  3. The study list consisted of 42 words divided into:

    • 18 loud

    • 18 quiet

    • 3 buffers from the primacy and recency effect

  4. After a 5-minute distractor task, participants engaged in free recall for 4 minutes.

Experiment 1: Results

  • A similar metacognitive illusion emerged for loudness as for font size.

  • Higher JOLs were reported for loud/larger words compared to quiet/smaller words, but no effect on recall was noted.

  • Implication: This illusion affects control by influencing re-study choices.

  • Participants were likely to choose to re-study quieter words, mistakenly believing that they had not learned the loud words as effectively.

Experiment 2: Restudy Choices

  • Experiment was designed identically to Experiment 1, but participants were provided with a restudy question after each JOL.

Experiment 2: Results

  • Participants chose to restudy a higher percentage of quiet words (M = 39%) compared to loud words (M = 20%).

  • It was observed that both volume (g = -0.50) and JOLs (g = -0.87) had a negative relationship with study choice.

  • Participants generally believed that quiet words were harder to learn than loud words, influencing their restudy decisions based on this metacognitive illusion.

Discussion

  • Perceptual cues significantly influence perceived memorability.

  • The concept of fluency (ease of processing) is central to understanding JOLs.

  • Students tend to choose to restudy items they believe are harder to learn, which may not align with actual recall ability.

The Ease of Processing Heuristic and the Stability Bias Kornell, Rhodes, Castel, Tauber (2011)

Stability Bias Overview

  • Kornell & Bjork (2009): People understand that studying impacts learning; however, they report similar JOLs for different study opportunities (1-4).

    • Additional study opportunities enhance recall, but global predictions regarding how many words would be recalled post-study do not vary with experience.

  • Koriat et al. (2004): Participants may express similar JOLs for retention intervals ranging from 10 minutes to one week despite increased intervals leading to less recall.

  • This suggests that, despite explicit awareness of forgetting, JOLs might mirror an underlying 'stable' memory perspective.

Ease of Processing and Recall

  • Larger font sizes yield higher JOLs compared to smaller font sizes (Rhodes & Castel, 2008).

  • Neither font size nor loudness influences actual recall.

Current Study Objectives

  • The aim is to explore the relationships (or disconnections) between memory, beliefs, and judgments.

  • Focus on how font size impacts JOLs without influencing recall, alongside how varying numbers of study opportunities affect recall but typically do not change JOLs.

Study Trials

Experiment 1

  • This experiment utilized words that were presented either once or twice during a spaced study.

  • Font size (large vs. small) was implemented as a within-participant variable.

  • JOLs were measured alongside recall, with no JOL during the second study opportunity.

Experiment 2

  • Built on Experiment 1, but compared 1 study opportunity versus 4 to determine saliency.

Experiment 3

  • Investigated beliefs without requiring task completion.

  • Participants read a description of Experiment 1 and made predictions based either on study opportunities or font size, informed by baseline performance numbers.

Example Results Discussion

  • Findings underscored a double dissociation between memory and JOLs:

    • Font Size: Effects on JOLs, not on recall

    • Study Trials: Impacts recall, not JOLs

  • Individuals frequently base judgments on immediate perceptual cues (e.g., fluency) without accounting for deeper beliefs.

Conclusions

  • The ease of processing heuristic suggests that fluency in processing and familiarity impact automatic predictions about recall.

  • Stability bias indicates that knowledge regarding memory must be consciously reconciled to overcome cognitive biases.

  • Metacognitive illusions present in monitoring can significantly influence efficient allocation of study time.
