An important new paper from the lab : in a few years, vision models have progressed to such an extent that they almost match human perception in the domain of geometry (but may still fall short of having a genuine language of shapes).

Apprendre à lire : ce que les données de 9 000 enseignants et 130 000 élèves révèlent des méthodes et de leur efficacité
Alors que la dernière enquête PISA sur le niveau des élèves note un net décrochage dans la compréhension de l’écrit, des études offrent des pistes pour améliorer l’enseignement de la lecture.

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.
