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...

I recently took part in an amazing experience at the “Solve for Healthcare & Life Sciences with Gemma” hackathon, organized by Google Paris! Our team worked on triage in emergency rooms, improving communication, prioritization and decision-making in critical circumstances.

Distinguishing performance gains from learning when using generative AI Comment by Lixiang Yan, Samuel Greiff, Jason M. Lodge & Dragan Gašević go.nature.com/3FJqTq3

🚀Join our team @tuda.bsky.social ! 🚀 I'm looking for 3 PhDs & 1 Postdoc for my @erc.europa.eu project “C4: Compositional Compression in Cognition and Culture” to study learning across individuals, teams, and cultural timescales 👉 PhD: hmc-lab.com/ERC_PhDs.html 👉 Postdoc: hmc-lab.com/ERC_Postdoc....

I'll be presenting two posters at #RLDM2025 in Dublin🇮🇪 – June 11, Poster Session 1: 🌀 Poster #19: How selective attention benefits and hinders learning in complex environments. 🏞️ Poster #18: NorMARL - a framework for sustaining shared resources through norm internalization.

Paris Magnolias at the Jardin du Palais Royal ⛅

🌍 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...

🤔 "What is an "explanation" of behaviou?" Always a good time to revisit this classic by the giant Herbert Simon, where he challanges - the idea that a cognitive revolution ever happened - neural reductionism - the utility of normative models and frameworks threadreaderapp.com/thread/15022...

New paper in #ProcB with @alexmesoudi.com, @jfbonnefon.bsky.social, @rmcelreath.bsky.social and Rob Boyd. We investigate how social learning shapes the way we explore and show that it can even preserve useless theories! 🧵👇

🚨New preprint alert!🚨 Achieving Scale-Invariant Reinforcement Learning Performance with Reward Range Normalization. Where we show that things we discover in psychology can be useful for machine learning. By the amazing @maevalhotellier.bsky.social and Jeremy Perez. doi.org/10.31234/osf...

New preprint! 🚨 Performance of standard reinforcement learning (RL) algorithms depends on the scale of the rewards they aim to maximize. Inspired by human cognitive processes, we leverage a cognitive bias to develop scale-invariant RL algorithms: reward range normalization. Curious? Have a read!👇

Check @anllohernan.bsky.social's latest published paper featured in Communications Psychology. Great collaboration with @urihertz.bsky.social and @nicholaraihani.bsky.social "Iearners manifest a preference for broadcasting useful experience-based information even at a social or economic cost"

Our latest paper with @urihertz.bsky.social , @nicholaraihani.bsky.social and @stepalminteri.bsky.social is a great occasion to post again in here! Come see how your own experience (and the costs of deciding to act) affect your tendency to give advice to others! www.nature.com/articles/s44...

A must-read for anyone thinking about using LLMs in social science research. LLM annotations (especially from closed, proprietary models) change unpredictably over time. And we don't know why. This is a huge problem for scientific reproducibility.
