New commentary: "Developing Minds Are More Than Biases in the Making" (with Tomás Lejarraga & Ralph Hertwig), responding to Santhanagopalan et al.'s call to study the origins of judgment and decision-making (JDM) in childhood. doi.org/10.1080/1047...

New preprint✍️😃🥳. An attenuated 'we' alongside a heightened 'they' in borderline personality disorder.

Very proud of @kirikuroda.bsky.social for preprinting this study on social influence and information cascades in experienced based decision making. osf.io/preprints/ps... @arc-mpib.bsky.social. Great collab with @simyciri.bsky.social @dirkwulff.bsky.social

Big news: I started a new position as Professor for Computational Social Science (W1 tenure track) at the Center for Critical Computational Studies (C3S) at Goethe University in Frankfurt am Main! www.c3s-frankfurt.de/who-we-are#m...

Very happy to see our ice-fishing paper on the cover of @science.org this week! 🎣🎉 We tracked large groups of Finnish competitive ice-fishers to study how social foragers use social information when searching for resources. 🐟 Link: www.science.org/doi/10.1126/... (contact me for open access)

🎉 My PhD work has just been published in @natcomms.nature.com! How do we learn who caused what - and how much control we had - when outcomes depend on multiple people? We studied how humans do so using a new social learning task, computational modelling and fMRI. www.nature.com/articles/s41... 🧵👇

NEW: We show and replicate socioeconomic gradients in heuristics for decision-making under uncertainty, possibly reflecting adaptations varying levels of scarcity and competition for resources 🫰 Shoutout and thanks to @danielnettle.bsky.social & @coraliechevallier.bsky.social ❤️‍🔥 tinyurl.com/mu7rzz6k

Do people judge what is going to happen in unknown situations differently depending on their socioeconomic position? Yes, if you experience lower socioeconomic position, you think the big rewards are even more unlikely to come your way: www.sciencedirect.com/science/arti...

It’s official! The postdoc positions announcement is here 🚀 If you know great candidates interested in attention, memory transformation and EEG, please help spread the word: Project (ReDAS) -> cimcyc.ugr.es/en/informati... Job offer -> cimcyc.ugr.es/en/informati...

Happy to share our latest study published in PNAS. Using data from 274,316 French students, we find that lower-SES students are less likely to wait for better university offers, even when waiting would lead to more prestigious or better-fit programs. www.pnas.org/doi/10.1073/...

Are you in Oxford / London this week? Paris beginning of next? Let’s catch up! You can also see what my latest work is about without catching up :)

Romanticisation of mental health problems in adolescence: what's the deal with that? 🌟 NEW PREPRINT by Awa Ndour and me 🌟 (Romanticise = to portray something as more desirable or positive than it really is) Brief summary below (🧵) osf.io/preprints/os... #PsychSciSky #DevPsychSky #ClinPsychSky

1/n 🆕📄: How do children learn to adapt to different environments when making repeated choices? And what do cognitive immaturity and probability matching have to do with it? Our new article explores how kids & adults differ in probability learning across statistical task structures: mpib.berlin/R3RFy

Want to make nice graphs with me, starting this summer? I am hiring for two PhD positions at the University of Witten/Herdecke.

Out in @naturehumbehav.bsky.social Can people tell true from false news? Yes! Our meta-analysis shows that people rate true news as more accurate than false news (d = 1.12) and were better at spotting false news than at recognizing true news (d = 0.32). www.nature.com/articles/s41...

If you are curios about risk taking and wonder whats up with adolescents, i had a conversation with Sofia on our podcast serios about it. Big thanks to @anasofiamorais.bsky.social, I really enjoyed our conversation! I am sure the rest of you will, too go check it out! :)

What is driving social foraging dynamics in the wild? In a new pre-print, we investigate decision-making mechanisms in large groups of Finnish ice-fishers competing for resources: osf.io/preprints/ps... Big thanks to drone pilot Félicie Dhellemmes. 1/n youtu.be/I_RH2diXcAk
