Judgments of learning (JOLs) impact item memory but not source memory: Insights into JOL reactivity using a...

Area of Science:

• Cognitive Psychology
• Metacognition
• Memory Research

Background:

• Judgments of learning (JOLs) assess memory understanding but can alter memory (JOL reactivity).
• Existing theories, like cue-strengthening and changed-goal accounts, propose different mechanisms for JOL reactivity.
• Understanding these mechanisms is crucial for accurate metacognitive assessment.

Purpose of the Study:

• To investigate the mechanisms underlying JOL reactivity.
• To differentiate between the cue-strengthening and changed-goal accounts of JOL reactivity.
• To determine whether JOLs primarily affect item memory or source memory.

Main Methods:

• Participants studied related/unrelated word pairs with colored fonts for source recognition.
• Hierarchical Bayesian modeling analyzed effects of JOLs on item, relatedness, and color memory.
• Experiments compared JOLs to judgments of relatedness (JORs) and examined study time allocation.

Main Results:

• JOLs and JORs strengthened item memory for both related and unrelated pairs.
• Neither JOLs nor JORs specifically enhanced source memory for relatedness.
• JOLs did not alter study time allocation, contrary to the changed-goal account.

Conclusions:

• Enhanced item memory appears to be the primary driver of JOL reactivity.
• Findings challenge existing explanations by highlighting the role of item memory enhancement.
• This study provides novel insights into the metacognitive processes influencing memory judgments.
