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. www.thetransmitter.org/decision-mak...

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.

We are thrilled to launch The State of Neuroscience in Latin America, a special report in which we spoke with nearly 50 researchers across Argentina, Brazil, Chile, Colombia, Mexico and Uruguay to capture the highs and lows of doing neuroscience research in Latin America.

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? :-) www.biorxiv.org/content/10.6...

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. www.biorxiv.org/content/10.6...

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 multiplic...

Super excited to share the first cooperative foraging paradigm in freely interacting mouse pairs! Stable leader and follower roles emerge spontaneously and predict learning. Well-trained mice show stereotyped, role-specific “behavioral motifs” absent in naive animals (1/5) doi.org/10.1101/2025...

Happy to share our new paper exploring how the brain might represent decision confidence. A population representation of the confidence in a decision in the parietal cortex: Cell Reports www.cell.com/cell-reports...

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 dec...
