📣Preprint: More effort, more variability. We formally tested underlying assumptions of effort-performance coupling. ↪️Performance increases non-linearly & becomes more variable at higher effort levels. 📖@ osf.io/preprints/ps... w/ @katjarewitz.bsky.social, @SilasWagner & @wanjawolff.bsky.social

Effort ≠ performance 🎯 At the Integrating Effort symposium @ASP, I showed that perceived effort maps non-linearly onto performance. Equal increases in prescribed effort produce disproportionately large increases in performance, likely because of compressed number representation and motor noise 🔢💪

We are excited to welcome Dr. Kristina Bruemmer to our team as a senior researcher and lecturer! 🎉

I had such a great time on this episode! 🤩 I really enjoyed taking the explore-exploit trade-off beyond theory and discussing its relevance for athletes, coaches, and performance in real sport settings. 🏀🏌️‍♀️🏃‍♀️ Thanks so much for having me @danabrahamspsych.bsky.social

New episode of The Sport Psych Show! On this week's episode "Exploit or Explore: Decision Making in Sport" I speak with University of Hamburg PhD student Katja Rewitz. Katja's research focuses on human sensations and their influence on decision-making and performance behaviour

Is your lab doing code reviews? I'd like to hear about your experiences and practices! In our teams, we'd like to establish internal peer-reviews of our research software. Our focus is on the correctness of our "one-off" analysis scripts underlying manuscripts. Because of that, the usual […]

Yesterday, we had the pleasure of welcoming Prof. Dr. Amitai Shenhav from UC Berkeley to our #DHPRlab meeting. He told us about neural and computational mechanisms of motivation, affect, and decision-making Thank you for taking the time and for the really engaging discussions @ashenhav.bsky.social🙏

Had an amazing time at the #ISSP conference in Hong Kong 🌆 Thanks for joining the hitchhike journey through the #effort research universe. Interested, check our preprint together w/ @wanjawolff.bsky.social & @israelhalperin.bsky.social ➡️ osf.io/preprints/ps...

Putting together a weekly book club for "Regression and Other Stories" (reply if interested!) and this page, "Common statistical tests are linear models," is a key motivation. If you git gud at regression, so much else comes along for free. lindeloev.github.io/tests-as-lin... #statsky

📺 A TV team from NDR visited our @dhprlab.bsky.social to learn about our current research & why boredom plays a powerful role in human behavior. You can spend three (German, but hopefully not boring) minutes watching it here: www.ndr.de/fernsehen/se... P.S. Thumbnail is not footage from our lab 😁

Truly enjoyed this talk held by Dr. Johannes Seiler 🎉 Interesting to discuss boredom as a signal that feels aversive but also secures us from stagnation 🙌🏼 Thanks for taking your time 👍🏼

Great pleasure to host Dr. Johannes Seiler in our #DHPRLab meeting! He gave a fascinating talk on how boredom drives exploration and information-seeking, and how neural entropy underlies this process across species. Thank you for sharing your time and insights 🙏

📣 #moeffortmoproblems “Just try harder and the success will follow” does does not always apply. Check out our latest preprint to learn more about this effort performance (de)coupling across domains and contexts 😎

Our team held yesterday’s lab meeting at Travemünde beach, enjoying the Baltic Sea and Hamburg’s maritime spirit as the ‘Gateway to the World.’ 🌊

Thanks again for the invitation and the great get-together 😎 That was truly fun talking about research methods, getting carreer advice, and ofc getting to know the typical local food "Frankfurter Grüne Soße" and "Handkäse" - can recommend 😜
