Do we learn differently from surprises as we age? We asked this using a RL task that deconfounded outcome probability & PE magnitude. Older adults learned more from large PEs than young adults. t.ly/DhjLo Fun teamwork w Dr. Christoph Koch Ondrej Zika Rasmus Bruckner

⭐️PhD in Cognitive/Computational Psychology⭐️ PhD alert! Do your PhD with me and use Reinforcement Learning to study how misinformation affects us. Deadline: October 7. Please RT! For more information: findaphd.com/phds/project/c…

Excited to share our brand-new work shedding some light on the neural mechanisms behind one of human’s coolest cognitive feats: compositional generalization of structural knowledge! A Tweeprint-Thread 🧵 1/n

Can LLMs do reinforcement learning in-context - and if so, how do they do it? Using Sparse Autoencoders, we find that Llama 3 relies on representations resembling TD errors, Q-values and even the SR to learn in three RL tasks in-context! Co-lead with the inimitable Can Demircan

🚨 New preprint on the role of eating disorder symptoms in accelerating response vigor during foraging decisions 💫 w/ Sam Hall-McMaster 📜Link: osf.io/preprints/psya… 💻Code and data: github.com/ozika/ed-forag… Funded by Humboldt-Stiftung Max Planck Institute for Human Development

Interested in getting hands-on skills in cognitive neuroscience? We are looking for 1-2 research assistants to support our research at @PB_UniHH Universität Hamburg Come work with our amazing team. Hamburg students from all departments are eligible. More about us: schucklab.gitlab.io

This is finally out today in PLOS Comp Biol - find the final updated and improved version here: journals.plos.org/ploscompbiol/a… with Nico Schuck summerfieldlab @summerfieldlab.bsky.social Andrew Saxe Paul Muhle-Karbe and twitterless Léo

Excited to announce that this work has now been published in PNASNews pnas.org/doi/10.1073/pn… We propose a computational account of how humans decompose complex dynamical experiences into subprocesses and reuse these in an abstract, compositional manner in novel situations.

Super excited to be going to #NeurIPS to present new work on softly state-invariant world models! We introduce an info bottleneck making world models represent action effects more consistently in latent space, improving prediction and planning! Reach out if you want to meet!

Friends, this is urgent. Families in Gaza are starving and need our help. I have donated to and been following this soup kitchen since they started. They provide hot meals to thousands & they need funds to keep going. Please consider donating & sharing. gofund.me/aab9459d

🚨Very excited that our (Luianta Verra Ingrid Martin & myself) RLDM 2025 Workshop "Game on: Leveraging Gamification to Understand Cognitive and Computational Mechanisms" has been accepted! We will soon be opening a call for contributed talks - stay tuned if you are interested!

It’s a Preprint! 👋 We show how we can dissociate perceptual from value-based mechanisms of generalisation + that stronger generalisation in anxiety is associated with value rather than perception. w/ Ondrej Zika Nico Schuck @BernhardSpitzer osf.io/preprints/psya… 1/n

Are you coming to RLDM #RLDM2025? Join our workshop on Gamification in Computational and Cognitive Neuroscience with an amazing speaker lineup! 🎮🧠🪄 w/ Ondrej Zika Ingrid Martin

Attending #CCN2025?  Come check out our poster tomorrow (Tuesday, A90) on how reward morphs neural representations of non-spatial cognitive maps in the hippocampus. Work w. Luianta Verra Alexander Nitsch Charley Wu (@thecharleywu.bsky.social) DoellerLab Nico Schuck 2025.ccneuro.org/poster/?id=VID…

Happy to share that after successfully defending my PhD last April with the great Nico Schuck , I will start a Postdoc with summerfieldlab @summerfieldlab.bsky.social on 1st of September. Grateful for the past, excited for the future!
