Our paper on effort-performance (de)coupling is now out at Neuroscience & Biobehavioral Reviews 🎉 Really interested? Read it open access here: www.sciencedirect.com/science/arti... Just a little bit interested? TL;DR in the thread below 👇

We had three extremely inspiring days coming together with a group of people who all think about #effort at our Effort Mini-(Un-)conference in Hamburg: discussing lots of open questions, sharing new ideas, thinking together about the challenges our field is facing, and having a great time! 🧠🚶🏼‍♀️🍴

Another two inspiring days with Prof. Chris Englert & his team from Goethe University Frankfurt! Many thanks for visiting and for making this such a great tradition 🌍🤝 Excellent scientific exchange, exciting shared projects, and some time to enjoy Hamburg’s landmarks together!

Our "Hitchhiker's Guide to Physical And Cognitive Effort" is now published in Sports Medicine🎉 Interested in the utility of effort definitions and proxies across domains, check the link ⬇️ link.springer.com/article/10.1... Huge Kudos to @wanjawolff.bsky.social & @israelhalperin.bsky.social 🙏

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....

📣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

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

#DHPRLab in the ISSP 16th World Congress in Hong Kong! Curious about our talks? Stay tuned 🙌🏼😌 @wanjawolff.bsky.social @senaozayotgonbayar.bsky.social @katjarewitz.bsky.social @lukas-hack.bsky.social Together w/ @corimartarelli.bsky.social, @mbieleke.bsky.social, and Darias Holgado.

Very happy to see this out now in Psychology of Sport & Exercise 🤓 If you’re interested in how the explore–exploit framework helps us study decision-making in sports and exercise, check it out! w/ @nicoschuck.bsky.social & @wanjawolff.bsky.social www.sciencedirect.com/science/arti...

📺 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 👍🏼

📣 #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 😎

New #DHPRLab preprint💪🥳 Check out Lukas's post below, in case you're interested!

Exciting milestone, my first PhD preprint is out! 🎉 Together w/ @israelhalperin.bsky.social & @wanjawolff.bsky.social, we put together A Hitchhiker’s Guide to Effort 🪐 If you’ve ever asked “what is effort, and how to measure it?”, this one's for you 😎 🚀 read it here: osf.io/preprints/ps...

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 😜

It's fun to play around with that new #stats tool by #Posit. Could be very helpful for quickly scanning your data frames 🎉

Friends don't let friends sit through 1000 trials to test the task works*.... Did you know you can simulate responses in PsychoPy? Install the PsychoPy "Monkeys" plugin and have a play! *Actually this is exactly what friends do 😅 - looking at you psychophysics people...

Such a pleasure to welcome @artefr.bsky.social to @dhprlab.bsky.social 🤩 We‬ talked about boredom & how it shapes our behavior. With cool insights from S. Kraus, @thomasandrillon.bsky.social & @jamesdanckert.bsky.social (who even reveals his boredom coping strategy 🎸) 📺 www.arte.tv/de/videos/12...

Was hyped to share some insights into how to navigate through the complex #effort maze @ ASP Conference in Bochum. Thanks for all the interesting discussions and talks, this was effortful but truly rewarding at the same time! w/ @wanjawolff.bsky.social & @israelhalperin.bsky.social

📢 New Publication 📢 Effort differentially shapes behavior before, during & after an action. w/ @bcheval.bsky.social, Silvio & Florent, we explore stage-specific effects of physical effort & how these dynamically modulate each other. Now out in Trends in Cognitive Sciences 🤩🤩 Curious? ⬇️

🎉 First preprint from my PhD! #excited We suggest that sport & exercise psych should adopt formal decision models to study how high-stakes contexts and self-regulatory demands shape the explore-exploit trade-off. w/ @nicoschuck.bsky.social @wanjawolff.bsky.social dx.doi.org/10.31234/osf...

Curious how #sports research can benefit from formal models of the explore–exploit dilemma & and how fundamental explore-exploit reseach can learn from studying decisions in sports? Check out the new preprint by our brilliant PhD @dhprlab.bsky.social student @katjarewitz.bsky.social! ⚽🧠
