Type-1 and type-2 decisions feature computational noise of similar magnitude - Communications Psychology
Zheng et al. show that confidence (Type-2) judgments feature the same magnitude of computational noise as perceptual (Type-1) judgments, with important implications for the debate on whether Type-1 an...

What does it mean for cognition to be Bayesian? The view that cognition is Bayesian inference is often intended at Marr's computational level. In a new paper in Nat Rev Psych, @kaixue98.bsky.social and I formulate the "explicit-Bayes" hypothesis that lives at the algorithmic level. rdcu.be/ff1XA
The explicit-Bayes hypothesis for cognition
Nature Reviews Psychology - It is often asserted that human cognition is Bayesian, but that broad claim is difficult to test in a falsifiable way. We suggest that researchers specifically assess a...

Our new paper is out in Cognition! What determines whether confidence follows the classic "folded-X" pattern vs. the "double-increase" pattern? The answer lies in the type of stimulus manipulation. Big thanks to my advisor Doby @dobyrahnev.bsky.social and co-first author @herrickfung.bsky.social !
Stimulus reliability but not boundary distance manipulations violate the folded-X pattern of confidence
The folded-X pattern has been identified as a critical signature of confidence: as conditions become easier, confidence increases for correct trials b…

My article "A comprehensive assessment of current methods for measuring metacognition" is finally out in Nature Communications 🎉 If you work on metacognition and think you know the psychometric properties of your favorite measure, you may be surprised. www.nature.com/articles/s41...
A comprehensive assessment of current methods for measuring metacognition - Nature Communications
Measuring metacognitive ability is one of the enduring challenges in cognitive science. The current paper develops formal tests of the quality of different measures and assesses how current metrics pe...

Great to see our research, led by @johannakuci.bsky.social, covered in The Transmitter. One of the more surprising findings to have come out of the lab.
The Transmitter @thetransmitter.bsky.social · last yr.Neuroscientists should embrace variability in neuroimaging studies, according to researchers who showed that decision-making is associated with subtypes of brain activity.
