🧵 I gave Claude two things: a short paper (doi.org/10.1073/pnas...) and a raw behavioural dataset with 3 lines of variable descriptions.
Then I asked it to fit three computational RL models described only by equations in the manuscript. No code, no toolbox, no guidance on the fitting procedure. 1/3

Have you ever wondered whether hunger state affects your choices in non-food domains? 👀
Make sure to check out our latest preprint, which sheds light on the mechanisms underlying the effects of hunger state on choice: osf.io/preprints/ps...
Thanks,Nils🙏 This study was a big motivation for ours: they found a spillover effect of hunger state on TD of money and music. We wanted to extend these findings by looking at different tasks + different commodities & the mechanisms more closely. In our design, we did not find any spillover effects.

In short: Hunger reshapes how you attend to and decide about food, but it does not spill over into other decision domains. Your hungry self isn't less patient or more selfish, just more drawn to tasty food 🍕
Our computational model (maaDDM2phi) confirmed the domain specific behavioral findings: hunger increased the weight on taste and the attentional discounting of health information. Model parameters in the intertemporal and social tasks were (largely) unaffected.
While attention (here: higher DT) predicted choice across domains, hunger state only altered attention in the food domain: hungry participants looked more at tasty options which increased the proportion of tasty choice (full mediation)
When hungry, participants chose tastier over healthier food options and responded faster to tastier options. However, hunger state did NOT affect intertemporal or social choice or RT. The effect was specific to the food domain.
We tested 70 participants in a within-subject design: each person completed food choice, intertemporal discounting, and social choice tasks — once hungry (overnight fast) and once sated (protein shake). Eye movements were recorded throughout.
Hunger makes us choose tastier, less healthy food, but does it also make us more impatient or selfish? Given the mixed evidence, we investigated the mechanisms underlying hunger state on choice using eye-tracking and computational modeling 👀🔍
🚨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🧵👇
I had a wonderful time at the #TeaP2026 in Tübingen. Thanks to the wonderful organisation, the inspiring scientific content and the lovely people there! Thanks to everyone in our little symposium! Looking forward to seeing you soon!
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.

Curious about how context influences decision-making? 👀🧠

Inspiring talk at our research colloquium yesterday! 🧠
Using very cool games (🦀🎰🐷🃏),
@sebraem.bsky.social showed when and how individuals flexibly adapt their learning across different environments.
We enjoyed a day packed of valuable discussions and delicious food!
A three by four grid of example stimuli found in the experimental buffet. The first column shows edible insects: meal worms, crickets, and buffalo worms. The second column shows novel savoury snacks for participants in the UK and Austria: Haldiram's Mullu Murukku, roasted broad beans, and Wah-Yuen fried dough. The third column shows common savoury snacks for the same participants: tortilla chips, crisps, and peanuts. The last column shows visually matched non-foods: Lego, wooden buttons, and wooden clothes pegs.
Figure with four panels. In each panel, the x-axis depicts the four types of stimuli: insect snacks, novel snacks, familiar snacks, and non-food. The top two panels show total dwell time across the experiment and average fixation duration. Overall, participants looked at the insects and novel snacks more than at the familiar snacks and non-food. The bottom panels show disgust and desire-to-eat ratings. Insects are scored as much higher on disgust and much lower on desire to eat compared to novel and familiar foods (both of which are rated low on disgust and relatively high on desire to eat).
Quick post on @jonaspotthoff.bsky.social new paper! We found people looked more at novel foods at an experimental buffet, including insects that they find gross! People suppress disgust avoidance when making foraging decisions.

Excited to share joint work with Ulf Hahnel and @sgluth.bsky.social on investigating how attribute translations - a widely implemented behavior intervention - lead to more ecological consumer choices. Main results are below, but check out our preprint 👇

Sollten wir uns öfter langweilen? 🥱 Dieser Frage geht unter anderem Sportpsychologe Prof. @wanjawolff.bsky.social von der Uni Hamburg in der @artede.bsky.social Dokumentation „42 – Die Antwort auf fast alles“ nach. Hier geht’s zum Video:
🥐 When we’re hungry, we pay more attention to taste than health, literally.
Eye-tracking and modelling show hunger shifts our focus toward calorie-rich foods and away from nutrition info.

Amazing sunny team event with our lab today! ☀️ We tackled an escape room aboard the historic ship Rickmer Rickmers - nothing like solving puzzles surrounded by maritime history ⚓🧩 So lovely bonding outside the lab and putting our problem-solving skills to work in completely new settings! 🤓
