Can we train ourselves to judge our own minds better?

What does the term "metacognition" refer to in cognitive psychology?

What metric does the signal detection theory parameter meta-d' isolate from first-order performance?

How is metacognitive efficiency mathematically indexed in this study?

It is calculated as the ratio of meta-d' to first-order performance (d'), often analyzed as log(meta-d'/d').

Why must researchers isolate metacognitive ability from changes in first-order performance during training?

Because first-order performance and confidence are positively correlated, improvements in actual task performance can mask or confound subtle shifts in metacognition.

Why was maintaining an accuracy level of approximately 75% correct important for the signal detection analysis?

It provides enough trials of hits, misses, false alarms, and correct rejections to reliably calculate d' and meta-d'.

What is the conceptual distinction between metacognitive efficiency and metacognitive bias?

Efficiency is how well confidence discriminates correct from incorrect trials (independent of performance level), while bias is the general tendency to report high or low confidence.

Did Bayesian analyses provide clear evidence for or against cross-domain transfer of isolated metacognitive efficiency?

No, the evidence for cross-domain transfer of isolated efficiency and bias was equivocal, meaning it could neither support nor refute it.

According to Latent Change Score (LCS) modeling, how did baseline metacognitive ability relate to training gains?

Individuals with lower baseline metacognitive calibration showed larger gains in response to training.

How did the temporal dynamics of confidence bias shifts compare to changes in metacognitive efficiency during training?

Shifts in confidence bias occurred immediately in the first training session, whereas metacognitive efficiency improved more gradually over all eight sessions.

What was the relationship between initial shifts in confidence bias and later changes in metacognitive efficiency?

Initial shifts in confidence positively mediated the subsequent increases in metacognitive efficiency.
