Judgments of learning reactively affect memory by inducing covert retrieval.

Area of Science:

• Cognitive Psychology
• Metacognition
• Memory Research

Background:

• Judgments of learning (JOLs) are known to affect memory recall, a phenomenon called JOL reactivity.
• The precise cognitive mechanisms underlying JOL reactivity remain debated in memory research.

Purpose of the Study:

• To investigate whether JOLs impact memory performance through covert retrieval.
• To compare traditional JOL reactivity paradigms with covert retrieval induction paradigms.

Main Methods:

• Utilized related and unrelated word pairs as learning materials across two experiments.
• Contrasted JOL conditions with no-JOL conditions under full and partial word pair presentation.
• Manipulated retrieval strength in the second experiment to assess its influence.

Main Results:

• JOLs enhanced memory for related word pairs in the traditional paradigm (full presentation).
• When target words were omitted (partial presentation), JOLs did not improve memory compared to no-JOL conditions.
• Results were consistent across both experiments, supporting the role of covert retrieval.

Conclusions:

• Covert retrieval significantly contributes to the JOL reactivity effect.
• JOLs enhance memory by inducing covert retrieval processes, particularly for related information.
