Spacing one's study: evidence for a metacognitive control strategy.

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Metacognition

Background:

• Learners' study strategies, specifically spacing and massing, significantly impact learning outcomes.
• Existing hypotheses suggest spacing is for long-term learning (spacing effect), massing is due to confidence illusions, or spacing is metacognitively controlled.
• Understanding how individuals regulate their study schedules is crucial for optimizing learning.

Purpose of the Study:

• To investigate whether individuals consciously control their study spacing strategies.
• To test three competing hypotheses: the spacing hypothesis, the massing hypothesis, and the metacognitive hypothesis.
• To determine the factors influencing learners' choices between massed, spaced, or no further study.

Main Methods:

• Participants studied cue-target pairs and made judgments of learning (JOLs) for each item.
• Following JOLs, participants chose to restudy immediately (massed), after the list (spaced), or not at all (done).
• Study choices were analyzed in relation to participants' metacognitive judgments of item difficulty.

Main Results:

• Results supported the metacognitive hypothesis, indicating learners actively control spacing.
• Participants chose to space study for items they judged as relatively easy.
• Conversely, participants chose to mass study for items they judged as relatively difficult.

Conclusions:

• Learners employ a metacognitively controlled spacing strategy, adjusting schedules based on perceived item difficulty.
• This finding highlights the role of metacognition in self-regulated learning and study strategy selection.
• Individual control over spacing is influenced by judgments of learning, suggesting a sophisticated approach to optimizing study.
