🚨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

Wow — thanks to this amazing community (you! 🥰 ), our book is now #1 among Amazon’s “Hot New Releases” in Medical Cognitive Psychology! 🙏🤩 Pre-order here: shorturl.at/Dxbif

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...

"Adaptive biases in the wild: Advancing our understanding of the nature of biases" The introduction (by Jochen Reb, Natalia Karelaia & Tomás Lejarraga )to the "Mind and Society" special issue on "adaptive biases" I had the pleasure to contribute to link.springer.com/article/10.1...

The winner’s curse — Behavioral economics anomalies, then and now. The presentation of Richard Thaler's (Chicago Booth) latest book, followed by a roundtable discussion, organized by the "An integrated approach of economic decisions" project. www.parisschoolofeconomics.eu/en/events/th...

Also found in the old sci-fi stash recently purchased in Bologna The plot’s crux is an illustration of the alignment problem (an all-powerful AI with wildly misaligned goals). Basically, the paperclip maximiser has gone rogue. (but do not expect great writing and depth of reflection)

🚨 New preprint 🚨 Are reinforcement learning models complete accounts of decisions from experience if they ignore explicit memory? In this new preprint, we show that people indeed form robust explicit memory representations that flexibly guide later decisions. 🔗 Preprint: doi.org/10.1101/2025...

🇪🇺 I am a bit late for this, but is important: R.I.P. Sofia Corradi (1934 – 2025), the beautiful mind behind the ERASMUS project, one of the most successful and beloved EU programme. It has changed the life (and mind) of ~15 million Europeans (including mine). en.wikipedia.org/wiki/Sofia_C...

Just read this old-school sci-fi gem I found in a vintage bookstore in Bologna, where a Practical Philosopher Corps is deployed across the galaxy to assess sentience and cognition in alien species. I guess the dream job for @birchlse.bsky.social @petergs.bsky.social

At a time when prominent thinkers like @anilseth.bsky.social Seth and Ned Block advocate a "strategic withdrawal" toward biologism in considering consciousness beyond the human case, our contrarian proposal is a methodological behaviourist computationalism. www.linkedin.com/posts/stefan...

🚨 New publication: How to improve conceptual clarity in psychological science? Thrilled to see this article with @ruimata.bsky.social out. We discuss how LLMs can be leveraged to map, clarify, and generate psychological measures and constructs. Open access article: doi.org/10.1177/0963...

Very thought-provoking post by @prakhargodara.bsky.social. Is confirmation bias/positivity bias a statistical "ghost" of model specification? Specifically not including temporally decaying learning rates? The evidence suggests this is not the case and here is why (1/n)

The associated online tool, however definitely nerdy, is addictive. Many kudos to @dirkwulff.bsky.social and co for setting this up and opening it to the community!

It was a real pleasure to be involved in the meta-scientific collaboration about the (historical, semantic and to some extent sociological) structure of the behavioral reinforcement learning field. Check @annaithoma.bsky.social thread below for more info!

Thought experiments such as the Blockhead and Super-Super Spartans are often taken as “definitive” arguments against behavior-based inference of cognitive processes. In our review -with @thecharleywu.bsky.social- we argue they may not be as definitive as originally thought.

I haven't given any news a while, I've been nose deep into this novel preprint with my excellent collaborators @stepalminteri.bsky.social, @urihertz.bsky.social and Bahador Bahrami: "Uncovering the semantics of teaching in experiential learning with Large Language Models". doi.org/10.31234/osf...

New (revised) preprint with @thecharleywu.bsky.social We rethink how to assess machine consciousness: not by code or circuitry, but by behavioral inference—as in cognitive science. Extraordinary claims still need extraordinary evidence. 👉 osf.io/preprints/ps... #AI #Consciousness #LLM

This book by @anilananth.bsky.social is great — perfect for those, like me, who have an intuitive and geometric grasp of math but unfortunately no formal training. Highly recommended!

Preprint alert! Navigating Inflationary and Deflationary Claims Concerning Large Language Models Avoiding Cognitive Biases. Very fun and efficient collaboration with @giadapistilli.com To help cognitively bounded humans balancing hype and dismall of LLMs capabilities osf.io/preprints/ps...

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!

Braitenberg's Vehicles arrived yesterday and I'm already halfway through it. An amazingly funny, clear, and lucid treatment of the question of attributing higher cognitive functions to artificial systems. Obviously very timely for current debates in AI

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/...

After 6 wonderful years together, it’s time to say goodbye. Farewell to Magdalena Soukupova – brilliant scientist, pillar of the HRL team, and amazing human being (sic.). Whatever lab you join next will be very lucky to have you

if you are already at #CCN2025 go check @nicolasyax.bsky.social work where we try to teach meta-cognition to LLMs in a very cool satellite symposium.

Tomorrow @isabellehoxha.bsky.social will present for the first time a multi-lab effort to build the CORTEX database, a highly curated human RL database to investigate the computational bases of relative value encoding: go check the principles and the preliminary results! (N=3800 and growing!)

Tomorrow at #CCN2025 @carolinepioger.bsky.social is going to present un update on a quite controversial line of experimental findings that challenge the common currency hypotheses of decision-making values These findings bridges reinforcement learning and description-based choices

🎉 Excited to present a poster at #CCN2025 in Amsterdam! 📍 Aug 12, 1:30–4:30pm We show that experiential value neglect (Garcia et al., 2023) is robust to changes in how options and outcomes are represented. Also, people show reduced sensitivity to losses, especially in comparative decision-making.

Last few days of #vacation in #sicily

Thrilled that our paper on the mechanisms underlying social learning strategies is out! First big paper from my @erc.europa.eu & @kawresearch.bsky.social funded group. More to come! I'm currently looking to recruit two post docs, get in touch if you find this line of research interesting.

EP #4 | @stepalminteri.bsky.social mentions that students shouldn't hesitate reading the old classics/papers in psychology/neuroscience. He also recommends
