Unity and diversity of metacognition

Area of Science:

• Cognitive Neuroscience
• Psychology

Background:

• Metacognition research aims to understand its underlying functional architecture.
• It remains unclear if a single metacognitive resource serves diverse cognitive functions.

Purpose of the Study:

• To investigate whether metacognitive ability is governed by universal or modular processes.
• To determine the relationship between online laboratory measures and offline self-report measures of metacognition.

Main Methods:

• Collected trial-by-trial confidence ratings in visual perception and episodic memory tasks.
• Utilized signal-dependent error awareness measures in an attention-to-action task.
• Employed correlational and latent variable approaches to analyze metacognitive efficiency across domains.

Main Results:

• Findings suggest a combination of domain-general and domain-specific metacognitive components.
• Metacognition in perceptual judgments appears largely domain-specific.
• Metacognition in attention-to-action and memory domains showed interrelations, indicating partly specialized subsystems.
• Offline self-report measures correlated with online metacognitive bias, not efficiency, questioning their validity.

Conclusions:

• Task-based metacognition is composed of both universal and specialized elements.
• Self-report measures may not accurately reflect metacognitive efficiency due to introspection and memory biases.
