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

Common statistical tests are linear models (or: how to teach stats)

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.

Very happy to see this out now in Psychology of Sport & Exercise 🤓

Die Kraft der Langeweile: Warum Nichtstun uns voranbringt Psychologe Prof. Wanja Wolff von der Uni Hamburg erklärt, warum Langeweile wie Schmerz wirkt: ein Signal, Kurs zu ändern.

📺 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 😎

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 🪐

A picture of our team in front of the Baltic sea

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...

Sollten wir uns öfter langweilen? - 42 - Die Antwort auf fast alles - Die ganze Doku | ARTE Langeweile hat einen schlechten Ruf. Und löst ein unerträglich dumpfes Gefühl aus. Dem wollen wir um jeden Preis entkommen! Wir greifen zu Alkohol und Drogen, werden aggressiv oder sogar gewalttätig. ...

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!

📢 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! ⚽🧠

Looking forward to your contributions—please share!

Does effort make life more meaningful? Was Sisyphus living the dream? In our new paper (now accepted in Cognition!), across 6 studies with nearly 3,000 participants, we found that more effortful tasks feel more meaningful 🧵

Very excited to talk about “Dynamics of Human Performance Regulation” in my inaugural lecture at @uni-hamburg.de.

I am very grateful for the nice turnout, the opportunity to share some of our @dhprlab.bsky.social research & explore ideas for future collaborations with so many amazing colleagues 🤩

#preprint 📢

Writing this was time-consuming, effortful, but never boring 🤩

w/ @senaozayotgonbayar.bsky.social, @jamesdanckert.bsky.social, @mbieleke.bsky.social & @corimartarelli.bsky.social, we explored how boredom and effort dynamically shape our experience of time: osf.io/preprints/ps...
