How “metacognitive” are confidence judgments? Do choice and confidence emerge together as we make a decision? In this piece for The Transmitter, I suggest that the answer may depend on the task. thetransmitter.org/decision-…

Is confidence a second thought—or part of the first one?

Neural circuits may sometimes calculate confidence in a decision simultaneously with the choice itself.

New preprint alert! Do words or numbers better capture our confidence? We found that words (eg "very likely") predict choice accuracy more reliably than numbers. I’m highly confident you’ll like it. Or is it 85% confident? :-) biorxiv.org/content/10.64898…

New preprint: visual attention may follow decisions more than it shapes them. We identify behavioral signatures inconsistent with models in which attention affects value, instead pointing to a substantial post-decisional component. biorxiv.org/content/10.64898…

Behavioral Signatures of Post-Decisional Attention in Preferential Choice

Attention plays a key role in decision-making by directing limited cognitive resources to relevant information. It has been proposed that attention also biases the decision process, due to a multip...

Do you "look at nothing" when making a decision? Here we provide further evidence about the connection betwee gaze into nothing and decision confidence, revealing more on the sequential hidden dynamics of decisions journals.plos.org/plosone/ar…

The relationship between confidence and gaze-at-nothing oculomotor dynamics during decision-making

How does confidence relate to oculomotor dynamics during decision-making? Do oculomotor dynamics reflect deliberation and the buildup of confidence in the absence of visual stimuli? Here we examine...

A population representation of the confidence in a decision in the parietal cortex

At the end of a decision based on evidence accumulation, the neural representation of the accumulation is invariant across decisions. Zylberberg and Shadlen show, nonetheless, that accuracy can be...

thanks to the great colleagues at @CNIR_IBS, settling in Korea has been going well. it's time to hire! we're looking for postdocs, grad students, & RAs, to work on projects like e.g. inducing blindsight in NHP via electrical microstimulations, or similarly via optogenetics ... 1/

Delighted to share this preprint! How is the confidence in a decision represented in the brain? With @shadlen we show that the lateral intraparietal (LIP) neurons that represent evidence accumulation also represent the probability that the decision is correct (i.e., confidence).
