🎁 Best birthday present this week was finally finishing and preprinting this big project: Together with @thorstenpachur.bsky.social, we investigated how loss aversion in risky choice is affected by how we learn about our options. 📖 Full-text here: lnkd.in/eKu2AEwB

📣 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.☺️

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 🤩 🧵

🚨 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...

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...
