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...

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.

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)

relationship between sensory evidence and confidence evidence

If you work with perceptual confidence judgments, you may be interested in our CNCB model of confidence ratings. Joint work with Vincent de Gardelle.

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...

Happy to share our new paper exploring how the brain might represent decision confidence.

Interesting, It might be fun to see whether individuals how can estimate their RTs more accurately also show greater metacognitive sensitivity.

🚨 Last chance to apply for this position! Lots of opportunities for learning, developing new projects, and collaborating with a large multi-national & interdisciplinary team. We're funded by an international organization with funding guaranteed for the next 3 years. Thanks for reposting!

Population Representation of the Confidence in a Decision in the Parietal Cortex Confidence in a decision is the belief, prior to feedback, that one's choice is correct. In the brain, many decisions are implemented as a race between competing evidence-accumulation processes. We as...

Fun read. Interesting to compare these findings with those of our recent study re-analyzing the same dataset. I suspect that both sets of findings stem from the same underlying principle, yet the approaches and implications are markedly different. www.biorxiv.org/content/10.1...
