🎉 New paper at Behavior Research Methods!!! We present the samplr package for R, which helps use sampling algorithms and cognitive models for human data - show theoretical background + examples. Thanks to @yunxiao-li.bsky.social and @asanborn.bsky.social. Paper link.springer.com/article/10.3...

The samplr package: A tool for modeling human cognition with sampling algorithms - Behavior Research Methods

Many models of cognition have sampling as a central component. Researchers have used them to explain human performance across a wide range of tasks involving perception, probability reasoning, and cho...

I've been working on improving webcam eye tracking for 3+ years and it's nearly ready to go. After a lot of ups and downs I'm in the excited phase again after the latest validation study!

📣 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.☺️

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...
