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)

Nijmegen friends: Tomorrow (10–12) I'll be debating Pim Haselager at a Donders Session on the thesis: "Artificial neural network models are adequate mechanistic models of the mind" I'm defending, he's opposing. Should be fun. Come join us! www.ru.nl/en/donders-i... @dondersinst.bsky.social

I'm hiring! 📢 Fully funded 4-year PhD position in Language Evolution using Communication Games at @mpi-nl.bsky.social. Come work with me on how different social pressures shape the evolution of new communication systems in the lab! Deadline for application is May 18th! share.google/fGTKbFS4v4Gb...

Classic predictive coding: V1 predicts low-level features, higher areas high-level. But recent studies + AI models suggest prediction happens at higher levels of abstraction. Who's right? In new work w/ @wiegerscheurer.bsky.social we find that both are – distinct regimes across the visual field

New preprint! w/ @mheilbron.bsky.social We found that, even during simple natural scene viewing, human visual cortex predicts—hierarchically in central vision and at higher levels peripherally—reconciling classical predictive coding with recent evidence from animal models and AI (e.g. JEPA) (1/10)

Job update: Next week I start as a group leader at the Planck Institute for Psycholinguistics in Nijmegen @mpi-nl.bsky.social 🧠 Building the Language and Predictive Computation group -- using LLMs to model language in the mind/brain, and vice versa. Hiring soon!

What is the relationship between memorization and generalization in AI? Is there a fundamental tradeoff? In infinitefaculty.substack.com/p/memorizati... I’ve reviewed some of the evolving perspectives on memorization & generalization in machine learning, from classic perspectives through LLMs.

Interesting convergence: The trick that made predictive self-supervised vision models work seems to be what the brain was doing all along w/ @predictivebrain.bsky.social: visual cortex is most sensitive to high-level prediction errors -- even in V1 Now published: journals.plos.org/ploscompbiol...

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

🚨New Preprint! How can we model natural scene representations in visual cortex? A solution is in active vision: predict the features of the next glimpse! arxiv.org/abs/2511.12715 + @adriendoerig.bsky.social , @alexanderkroner.bsky.social , @carmenamme.bsky.social , @timkietzmann.bsky.social 🧵 1/14

This is, without a doubt, the best popular article about current state of AI. And on whether LLMs are truly 'thinking' or 'understanding' -- and what that question even means www.newyorker.com/magazine/202...

New paper on memorability, with @davogelsang.bsky.social !

New preprint out together with @mheilbron.bsky.social We find that a stimulus' representational magnitude—the L2 norm of its DNN representation—predicts intrinsic memorability not just for images, but for words too. www.biorxiv.org/content/10.1...

New preprint! w/@drhanjones.bsky.social Adding human-like memory limitations to transformers improves language learning, but impairs reading time prediction This supports ideas from cognitive science but complicates the link between architecture and behavioural prediction arxiv.org/abs/2508.05803

CCN has arrived here here in Amsterdam! Come find me to meet or catch up Some highlights from students and collaborators:

We are excited that Ellie Pavlick from Brown University & Google DeepMind will be the third keynote speaker of CCN2025! Join us in August for the 8th CCN conference, on cognitive science, neuroscience, and AI. Details on paper submission (both short & full length papers) below!

Cog-sci folks!
What's your favourite platform for developing/running online studies? I’m looking for something that: 1) integrates with prolific; 2) requires minimal web-development experience, ideally just python.

Key-value memory is an important concept in modern machine learning (e.g., transformers). Ila Fiete, Kazuki Irie, and I have written a paper showing how key-value memory provides a way of thinking about memory organization in the brain: arxiv.org/abs/2501.02950

Felix Hill was such an incredible mentor — and occasional cold water swimming partner — to me. He's a huge part of why I joined DeepMind and how I've come to approach research. Even a month later, it's still hard to believe he's gone.

Column | De wooncrisis is misschien wel de belangrijkste oorzaak van het chagrijn in Nederland, maar er gebeurt niks of zelfs precies het verkeerde.

In welke bochten het CU en CDA zich ook wringen, het is een bezuiniging op het hoger onderwijs om belastingkorting mogelijk te maken voor het grote bedrijfsleven, en wat snippers voor het volk.

Maar je kiest er wel voor. De rest is retoriek. Je. Kiest. Hier. Voor. Own it.

How do LLMs learn to reason from data? Are they ~retrieving the answers from parametric knowledge🦜? In our new preprint, we look at the pretraining data and find evidence against this: Procedural knowledge in pretraining drives LLM reasoning ⚙️🔢 🧵⬇️

After a great conference in Boston, CCN is going to take place in Amsterdam in 2025! To help the exchange of ideas between #neuroscience, cognitive science, and #AI, CCN will for the first time have full length paper submissions (alongside the established 2 pagers)! Info below👇 #NeuroAI #CompNeuro

1/ Here's a critical problem that the #neuroai field is going to have to contend with: Increasingly, it looks like neural networks converge on the same representational structures - regardless of their specific losses and architectures - as long as they're big and trained on real world data. 🧠📈 🧪

I can't believe we could actually see this happen. It is one of the weirder and more impactful climate change tipping points. And as Genevieve says, "If it collapses it would be very, very hard for many, many people to eat." We simply can't let it happen

Emerging from a bsky-slumber to ask a question that was perhaps too difficult for cog-sci twitter: What’s your favourite (historical) example of *groupthink*, where an idea was widely accepted in cog/neuro science despite ample contradictory evidence, or despite the lack of empirical support?
