Participants can improve memory performance by using reliable external recommendations, especially if they have strong metacognitive monitoring skills. Feedback did not enhance the use of these recommendations.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Human Memory
Background:
- Previous research focused on negative impacts of misleading external information on memory.
- The role of reliable external cues in enhancing memory judgments remains less explored.
Purpose of the Study:
- To investigate if participants can leverage valid external recommendations to improve memory performance.
- To examine the influence of metacognitive monitoring and feedback on the utilization of external recommendations.
Main Methods:
- Two experiments were conducted using recognition tests with varying levels of material encoding.
- Participants received explicit external recommendations (e.g., "Likely Old/New") with different validity rates (65%-85%).
- Metacognitive monitoring ability was assessed in the absence of recommendations, and performance feedback was provided in some conditions.
Main Results:
- External recommendations significantly improved discrimination performance compared to conditions without recommendations.
- The benefit of recommendations was moderated by participants' metacognitive monitoring ability.
- Corrective feedback did not enhance participants' ability to effectively use external recommendations.
Conclusions:
- Individuals can enhance memory judgments by incorporating reliable external recommendations.
- The effectiveness of external recommendations relies on an individual's metacognitive sensitivity to their own memory signals.
- Metacognitive monitoring in recognition tasks is not readily improved through corrective feedback.
