I'm heading to #CogSci2026 @cogscisociety.bsky.social this evening, looking forward to seeing lots of new & familiar faces! 🇧🇷 I'll be presenting this paper: A measure of metacognitive bias you can be confident in 📍: T.18.3 🗓️: July 24th, 2-3:30pm 👥: @tianqizhan.bsky.social @smfleming.bsky.social

In a new preprint w/ @tianqizhan.bsky.social & @smfleming.bsky.social, we developed a new measure of metacognitive bias (over/under confidence in individual decisions)! doi.org/10.31234/osf...

Interested in how we plan over our imagination? Come to Brazil 🇧🇷 & my poster P1-E-37 at #CogSci2026! Here, @smfleming.bsky.social and I use computational modelling to demonstrate that planning over our imaginations, untethered from perception, relies on mental representations.

Are you interested in metacognition/ individual differences/ Bayesian modeling/ psychometrics? I'm thrilled to present our poster at #CogSci2026 🇧🇷 next week! Come check it out and chat! 📍Poster number P1-E-41 📅 2:45 pm, July 23 👥 @jasondasilvac.bsky.social @smfleming.bsky.social

Out now in eLife, our new and improved paper on Attention and planning. Here, we explore how attention acts like an inductive bias that selects relevant information on which to plan. 📍🗺️👀 (1/5) elifesciences.org/articles/108... @smfleming.bsky.social

How attention simplifies mental representations for planning

Spatial attention controls the information people become aware of and, in turn, incorporate into simplified perceptual representations for use in multi-step planning.

Our paper "Neural timescales from a computational perspective" is finally out in @natneuro.nature.com: www.nature.com/articles/s41... We discuss how computational models and methods can distill empirical observations on neural timescales into quantitative, testable theories of brain computation.

I am recruiting a postdoctoral researcher and a PhD student, funded by a new ERC grant. The grant focuses on the role of the hippocampus in visual perception, using 7T fMRI (hippocampal subfields, cortical layers) and MEG+iEEG. The intended start dates for both positions are in early 2027. 🧠🟦 1/3

NEW PAPER🚨👀 in Science Advances with a wonderful transatlantic team. (incl @sylvainbaillet.bsky.social @olejensen.bsky.social @katduecker.bsky.social) Using human MEG, we found lower-order and higher-order neural processes that underlie illusory transitions in conscious visual perception. 🧵👇

Hierarchical brain dynamics supporting visual perceptual transitions

Illusory transitions in conscious visual perception involve both early visual cortex and higher-order motor cortices.

Now in press one of my last PhD projects! We traced the neurobiological profile of fMRI BOLD signal variability, a measure that has been related to age, behaviour, disease status, but had not yet been fully contextualised within the brain's multiscale architecture. www.nature.com/articles/s41...

Very proud to announce that the final chapter of my thesis is now out in Cell Reports! How do neurophysiological traits that characterize individuals evolve across the lifespan?
