Prakhar, in a recent thought-provoking paper and thread, boldly claimed that the learning-rate biases may be mere “statistical ghosts” of decaying learning rates We took up the challenge and put this claim to the test. Here are our findings (w/ @romanececchi.bsky.social). 1/n osf.io/preprints/ps...

I’m happy to share a short opinion piece I’ve just finished, where I revisit the famous Skinner vs. Chomsky exchange on how language is learned through the lens of today’s large language models (before getting mad read the rest) 1/n osf.io/preprints/ps...

🚨Friends, we’re happy to share that our book is available for pre-order! 🎉 We aimed to cover all the foundations of the topic in an accessible manner for a large audience. It could help set up a bachelor-level curriculum on the topic. Pre-orders are very key for the fate of books: shorturl.at/Dxbif

New pontification piece with @awestbrook.bsky.social and Jean Daunizeau, just out in TICS: Why is cognitive effort experienced as costly? (or why does it hurt to think) never written a review paper before in my life, that was a new and unusual experience

Our latest preprint where we show (among other things!) that the main effect of complete feedback information is increase risk (not performance) in experience-based show. We also show that the description experience gap is not due to sampling issue osf.io/preprints/ps...

My paper is out! Computational modeling of error patterns during reward-based learning show evidence that habit learning (value free!) supplements working memory in 7 human data sets. rdcu.be/eQjLN

🧠Our new preprint is out on PsyArXiv! We study how getting more feedback (seeing what you could have earned) and facing gains vs losses change the way people choose between risky and safe options. 🖇️Link: doi.org/10.31234/osf... It's a thread🧶:

Check out @bcdavidson.bsky.social's preprint (w/ @georgiaturner.bsky.social @orbenamy.bsky.social @livia-tomova.bsky.social and co.) about the (computational) consequences of social isolation in social media use during covid!

New paper our in @pnas.org, lead by @isabellehoxha.bsky.social with Léo Sperber. We use evolutionary simulation to assess and compare the adaptive value of positivity bias and gradual perseveration in reinforcement learning. Follow the thread below (and Isabelle!) for more details!

Ever wondered why you keep going to that restaurant with stale fries? Is it because you went often in the past (perseveration) or because you remember past good experiences better (positivity bias)? Our study out in PNAS investigates the normative basis for these biases www.pnas.org/doi/10.1073/...

I'm feeling very glad & grateful these days to be part of neuroeconomics summer school in Fontainebleau! 👾

Hi, we will have three NeuroAI postdoc openings (3 years each, fully funded) to work with Sebastian Musslick (@musslick.bsky.social), Pascal Nieters and myself on task-switching, replay, and visual information routing. Reach out if you are interested in any of the above, I'll be at CCN next week!

Excited about #CCN2025 and sharing our research in @cmc-lab.bsky.social!

I've recently come across Ariel Rubinstein's argument that models are stories, mathematical ones, but stories nonetheless. Economic models should be viewed like fairytales: they illustrate specific ideas within narrowly defined settings but shouldn’t be assumed to offer \

Using a gamified punishment task, this study identifies specific learning and decision-making deficits that drive robust, consequential differences in choice within an international population sample across a 6-month interval. @philjrdb.bsky.social @gavan.bsky.social www.nature.com/articles/s44...

🌍 Excited to share that our paper has been accepted for an oral presentation at the International Conference on Complex Systems (FRCCS) 2025 in Bordeaux! We demonstrate how norm internalization and learning rate influence sustainability, via a cognitively grounded multi-agent RL framework.

🧵 New preprint out! 📄 "Elucidating attentional mechanisms underlying value normalization in human reinforcement learning" 👁️ We show that visual attention during learning causally shapes how values are encoded w/ @sgluth.bsky.social & @stepalminteri.bsky.social 🔗 doi.org/10.31234/osf...

🚨Preprint update!🚨 with @thecharleywu.bsky.social Are Large Language Models (LLMs) conscious? 🧠💻 Most say: only if they replicate the brain's computations. But we propose a shift: consciousness should be inferred from their behavior. osf.io/preprints/ps...

🚨 New study alert! 🚨 Ever wondered if rats and humans learn in the same way? 🐭🧑‍🔬 We tested this — and the answer is yes, at least when it comes to how we value rewards in context. (with @shaunaparkes.bsky.social Lachlan Ferguson, Magdalena Soukupova) 🧵Thread 👇 1/ www.biorxiv.org/content/10.1...

Thrilled to share my first post here with something I’m truly proud of; My PhD paper is finally out in @commspsychol.bsky.social. Thanks to amazing @ktsetsos.bsky.social for his wise insights and our reviewers for their constructive comments. You can read the full paper here: rdcu.be/eguDX 1/10

🎙️ EP #14 What are the multiple ways in which social media 'might' affect mental health? What can parents do, given the messy state of the scientific literature? @adigitaltanay.bsky.social discusses this & much more with @orbenamy.bsky.social tinyurl.com/5eum2vxm [Jon Haidt Easter Egg in 🧵 below]

Extreme stances about AI and LLMs in particular (be them deflationary or inflationary) are very likely wrong, valid and certainly not good for an healthy debate. But where do they come from? We (with @giadapistilli.com) argue that common cognitive biases may play a role: osf.io/preprints/ps...
