📣 NEW PREPRINT ALERT! 📣 📝Preprint: www.biorxiv.org/content/10.6... When choosing between options with multiple attributes, what does the brain actually compare - individual attributes or integrated option values? We combined EEG + eye-tracking to find out... and found evidence for the latter 🧠

Fixation-evoked potentials reveal neural signatures of hierarchical value-integration during decision-making

Many decisions require maintaining beliefs across multiple levels of representation, from sampling and integrating information to forming action plans. To elucidate these processes and reveal the neur...

Last week, we had our 2nd lab retreat at Schloss Basthorst! 2.5 days, 16 scientific sessions, German herbs, a boat tour, and lots of good company and team-building.🌿🍵🚤 Grateful to our amazing team for all the effort, ideas, and energy they brought along! A little glimpse of our retreat.☺️

Happy to share that a new publication is now out!🎉 If you want to set up or improve your lab, this paper offers a shared vocabulary for thinking about laboratory infrastructure as an integrated system. Read the full paper here: peercommunityjournal.org/articles/10....

Happy to share our new preprint, "Modeling Environmental Behavior: Lessons from Social Computational Neuroscience". A big thank you to my co-authors @annesaulin.bsky.social, @tony-craig.bsky.social, Caroline Moraes, Yansong Li, Chunliang Feng, and @lei-zhang.bsky.social osf.io/preprints/ps...

This is a bit of a deviation from my usual effort & boredom research: with Johannes Keyser and @sgluth.bsky.social I have been working on a passion project on what makes a lab good, flexible, and future-proof. Not about AI or stats, but the physical hardware and how devices talk to each other 🤩 🧵

✨I am excited to share that I have joined the @tum.de School of Management, where I will be continue researching the mechanisms underlying dietary decision-making together with @thorstenpachur.bsky.social and his team ✨

🚨 New preprint with @sgluth.bsky.social on social learning and EEG! 🧠 We've recently found out that, to learn about others' preferences, humans don't just look at WHAT they choose, but also HOW FAST they make a decision. How does the brain actually process this? 👇 osf.io/preprints/ps...

🚨New preprint alert🚨 Does hunger affect your decisions beyond food? We tested whether being hungry affects attention & choice across food, intertemporal and social domains. Spoiler: the effects of hunger state on attention and choice are more limited than you might think🧵👇

How do people search for information to make efficient decisions? Our new theory, now out in Psychological Review, suggests that an efficient search rule is (at the core of) the answer. And eye-tracking data support our theory. Check out here (it's open access): psycnet.apa.org/fulltext/202...
