Are you new to the field of Computational Psychiatry or just looking for resources on applying Bayesian models of cognition to behavioural data? Then check out our new paper "Bayesian Workflow for Generative Modeling in Computational Psychiatry": doi.org/10.5334/cpsy.116

How do we process uncertainty, and how do neurometabolites shape this?🧠Here we use a combination of computational modeling 7T MRS to answer these questions: biorxiv.org/content/10.1101/…

We are indescribably sad to announce the passing of our dear friend and colleague Kristian Tylén
His presence at the IMC will be forever missed and his impact on us all is beyond words
Our thoughts are with his wife and children in this difficult time

Super excited to share our new preprint, led by my supervisor Franziska Knolle in collaboration with Verena Demler, @Lucy_MacG & @chmathys:
💡Guided by Expectations: Overweighted Semantic Priors in Schizotypy and their Links to Glutamate

Great to see this out - congratulations @D_Atanassova !

Higher levels of psychopathic traits were associated with reduced pain sensitivity and a greater tendency to ignore new evidence and maintain prior expectations in pain learning situations. nature.com/articles/s44271-0…

🧵Why do people with psychopathic traits stick to maladaptive patterns of behaviour?
The answer: a cognitive rigidity mechanism prompts them to ignore new evidence and maintain prior expectations in pain learning situations. 1/3

Here's a copy of @lilwebian's thread on the generalized HGF arxiv.org/abs/2305.10937 👇

This is work with @chmathys, @PTWaade, Nicolas, Anna and Klaas.
For the actual thread, come to where the skies are blue!

We also provide some examples for the kinds of models you can now build within the HGF framework – from global volatility beliefs, multimodal inference, multisensory cue combination over time, etc etc – check it out! arxiv.org/abs/2305.10937

This has been a long haul – the main work was done as part of @lilwebian's PhD at the #TNU @ETH_en, with Klaas and me. Years later, Nicolas, @PTWaade and Anna came onboard and made shiny toolboxes from our initial codebase. First preprint May 2023. Glad to finally share it!

If you want to have a chat about this, meet me today at #IWAI2024 or the rest of the week at the #CPC in Zurich. There, we will also present the new toolboxes implementing all of this:
github.com/ilabcode/pyhgf (led by Nicolas)
and github.com/ilabcode/Hierarch… (led by @PTWaade)

Long overdue #tweeprint: ✨The generalised hierarchical Gaussian filter✨
Ever wanted to build your own hierarchical Bayesian learning model without deriving/implementing new equations? Ever wondered how the HGF relates to predictive coding?
