Is our ability to judge our own minds general or task-specific?
An individual's ability to accurately evaluate their own performance is largely shared across different mental tasks, supporting a domain-general metacognitive ability.

Is there a G factor for metacognition? Correlations in retrospective metacognitive sensitivity across tasks
What they did
The researchers recruited 181 young adults to test whether metacognition operates as a single, general process or depends on the specific type of task being performed. Each participant completed four cognitive tasks—episodic memory, semantic memory, executive functioning, and visual perception—consisting of 40 trials each. After every trial, participants rated their confidence in their answer on a scale from 0% to 100%, allowing researchers to calculate both their overall confidence bias and their metacognitive efficiency.
What they found
The researchers found that both confidence levels and metacognitive efficiency correlated significantly across almost all tasks. Specifically, five of the six correlation pairings for metacognitive efficiency did not overlap with zero in their statistical models, indicating a shared cognitive resource for self-evaluation. Depending on the tasks compared, this general metacognitive ability explained between 7% and 48% of the variance in how accurately participants judged their own decisions. Only the relationship between episodic memory and visual perception failed to show a clear correlation, with an estimated correlation of 0.28.
The limits
What it doesn't show
Although the study supports a general metacognitive process, it cannot determine whether this shared resource can be trained to improve performance across different fields. Furthermore, because each of the tasks only featured 40 trials, there was higher statistical uncertainty when calculating individual performance measures. Finally, the correlational nature of the design means we cannot conclude whether a single brain region or multiple interconnected systems drive this shared ability across different domains.
Key terms
- Metacognition
- The capacity to monitor, evaluate, and control one's own cognitive processes.
- Metacognitive bias
- An individual's general tendency to report high or low confidence in their responses, regardless of how accurate they actually are.
- Metacognitive sensitivity
- The ability to accurately distinguish between one's own correct and incorrect decisions when making confidence judgments.
- Metacognitive efficiency
- A measure of metacognitive sensitivity that has been mathematically adjusted to control for differences in a person's actual task performance.
- Signal Detection Theory (SDT)
- A mathematical framework used to model and separate an observer's genuine sensitivity to information from their decision biases.
- Retrospective confidence judgments (RCJs)
- Self-evaluations made after a decision or action regarding the likelihood that the response was correct.

In the study of metacognition, what is the key difference between a domain-general and a domain-specific view?
Common questions
Why is it important to control for actual task performance when measuring metacognition?
If a task is extremely easy, a person will naturally get more answers correct and feel highly confident. Without controlling for performance, it is impossible to tell if a correlation between tasks is due to genuine self-awareness or simply because a participant is highly skilled at both tasks.
Why did the researchers use a hierarchical Bayesian model to analyze their data?
With only 40 trials per task, individual measurements can be highly unstable and noisy. The hierarchical Bayesian approach helps stabilize these estimates by allowing group-level patterns to constrain individual parameters, leading to more accurate correlation estimates.
Why didn't episodic memory and visual perception correlate as strongly as other task pairs?
The authors suggest that episodic memory relies heavily on subjective, internal cues that lack a consensual consensus of difficulty, whereas visual perception relies on objective, easily inferable difficulty differences (like the clear difference in dot counts), making a general self-evaluation strategy less transferable between them.
Can I improve my metacognition in school by practicing it in video games?
While this study suggests a shared resource exists, it does not directly test intervention effects; however, the presence of a domain-general resource suggests that training self-evaluation skills in one area might theoretically transfer to others.
