    Locus coeruleus connectivity at 3T based on individual localization using a neuromelanin sensitive sequence as compared to MNI space masks. Results largely converge, though the TPJ may be driven by other nuclei. Good news for atlas-based analyses!

    Decisions between >2 options are tricky. In our newest work, we could not replicate a previous “divisive normalization” or “distractor effect” in decisions btw 3 food snacks. But we found remarkable dynamic interactions between valuation & attention: (1/6)

    For years, I simulated perceptual/cognitive model predictions by running a large but fixed number of simulations (whether 250 or 10,000). Until Bas and Luigi opened my eyes to the errors of my way. Check out their preprint for a powerful combo of enlightenment and code.

    I've just released a fairly lengthy paper on defining & measuring intelligence, as well as a new AI evaluation dataset, the "Abstraction and Reasoning Corpus". I've been working on this for the past 2 years, on & off. Paper: ARC:

    And now after more than 1 hour waiting they propose me to take a train later and say that this is not their fault.

    Incredibly bad service at in Paris. 6 people!!!! to check in 1 bag for more than an hour. If you are up for this service pay 34 euros and you are good to go.

    I wrote this paper arguing that the inferential statistics we report in psychology papers are so disconnected from the hypotheses they're meant to test that they may as well be made up. feedback is appreciated.

    Au milieu de toute cette hystérie médiatique sur « les écrans », l’analyse précise et prudente de Franck Ramus, membre du CSEN, est vraiment bienvenue. « cet effet est très faible, sans doute trop faible pour justifier des recommandations alarmantes de santé publique. »

    Our latest from . Using a "task remapping" paradigm, we show reinforcement learning problems are abstracted, and these abstract representations can be generalised to new problems.

    Check out our new preprint about the interaction between agency and valence-related reinforcement learning biases (w/ , H. Théro, M. Vidal, and ). Spoiler alert: the confirmation bias is specific of free choices

    NEW PREPRINT: interacting with volatile environments stabilizes hidden-state inference and its brain signatures! We compare human reasoning based on cues (as in perceptual decisions) vs. outcomes (as in reward-guided decisions) using a new agent/observer task. Read on! (1/n)

    Dépêchez-vous, le documentaire dédié au génie de la peinture 🎨 Egon Schiele n’est plus disponible pour très longtemps ! 😱 Ce serait bête de passer à côté d’un tel chef-d’œuvre. ➡

    People don't act like Bayesians when making sequential decisions; instead they look like they have two discrete confidence levels

    Curious by choice or by chance? New bioRxiv preprint from my group: “Computational noise in reward-guided learning drives behavioral variability in volatile environments”! We show that a large fraction of choices labeled as exploratory is due to limited learning precision.
