When children start school, how do their brains change to support learning of formal mathematics? Our new paper, with @standehaene.bsky.social, just out in PNAS, followed ~50 children with yearly fMRI scans over 3 years, from preschool to 2nd grade, to see how this network develops. 🧵

Why is reading so fundamental to the human mind? In this fascinating paper, @standehaene.bsky.social & Co show how literacy reshapes and connects the brain’s visual and language systems. A timely reminder of what education could lose if LLMs replace reading & writing. www.unicog.org/publications...

In this new JEP:General paper, we show that geometric shapes are organized as tree structures in a language of thought. We apply several linguistic tests for nested constituents, including structural ambiguity, constituent subparts, and syntactic movement, and find analogues in the visual domain.

Selon Stanislas Dehaene, notre cerveau possède des langages internes de la pensée qui auraient précédé l’apparition du langage parlé. Son dernier livre se penche sur les origines de la géométrie.

New peer-reviewed paper w/ @mheilbron.bsky.social, @predictivebrain.bsky.social & Jakub Szewczyk! Pre-onset brain encoding has been taken as evidence that brains–like LLMs–predict upcoming words. We show that the same signatures arise in systems that cannot predict. (elifesciences.org) (1/8)

New paper 🌟out now in Nat. Neurosci.: www.nature.com/articles/s41.... With advisors @davidpoeppel.bsky.social and @Nai! We show that, while LLMs are optimized to predict the next word, the human brain modulates prediction efficiency by strategically grouping words into constituents. 1/n More 👇
