Do elite athletes benefit from instruction and feedback from a coach? In our new preprint (biorxiv.org/content/10.110…), we tested whether slalom racers learn to make better strategy choices and therefore perform better with reinforcement learning than with instruction-based learning

EP #4 | @StePalminteri mentions that students shouldn't hesitate reading the old classics/papers in psychology/neuroscience. He also recommends

For people who published/conducted Stage 2 registered reports, have you ever had issues that required significant deviations from the Stage 1 and how have you handled this? Are there any instances where this did not lead to rejection?

Dear sport scientists: stop saying things like “expertise development is non-linear” unless you can show what that actually means. Most of the time, you can fit a simple linear model: y = a·x + b and it works just fine. Sadly, “non-linear” has become a buzzword

Another study showing the huge uptake, and very favorable evaluations, of preregistration (this time in experimental economics). This is by now a very established result. Mainly the older generation who is negative about is. econstor.eu/bitstream/1041… 1/3

But I hope my admittedly bitter comments will invite others to consider how they can make women feel safer in this profession. My own experience is that nobody steps forward when the abuse is happening. They could but they choose not to. Why?

I have guested a podcast about motor learning together with Casper Ruud’s coach. We discuss reinforcement learning and deliberate practice 💪 open.spotify.com/episode/3cxFsN…

Joined in on the first qualitative interview @sajedeh_rasti is doing for her PhD, interviewing scientists involved in large scale coordinated projects. Incredibly interesting. Qualitative research and talking to scientists in other disciplines is providing a wealth of information

In a one-shot prisoner’s dilemma game, manipulating the location of payout information on computer screens changed participants’ gaze pattern sequences and resulted in greater cooperation when more focus was given to others’ outcomes. @arkadykonovalov nature.com/articles/s4427…

Iceland stands with Ukraine. You are not alone. We wholeheartedly support Ukraine in their quest for just and lasting peace against the unprovoked and unlawful Russian aggression.

Trump berates Zelensky, the leader of a democratic country courageously fighting Russian imperialism, while he allies himself with Putin, a dictator who started the bloodiest European war in 80 years. Sorry, President Trump. We believe in democracy, not authoritarianism.

Ukraine is not to blame for this war brought about by Russia’s illegal invasion. We stand with Ukraine. 🇺🇦 🇮🇪

Finland and the Finnish people stand firmly with Ukraine. We will continue our unwavering support and work towards a just and lasting peace. 🇫🇮🇺🇦

The Netherlands supports Ukraine as firmly as ever. Now more than ever. We want a lasting peace and an end to the war of aggression started by Russia. For Ukraine and its people, and for Europe.

Luxembourg stands with Ukraine. You are fighting for your freedom and a rules based international order. 🇱🇺🇺🇦

There is an aggressor: Russia. There is a victim: Ukraine. We were right to help Ukraine and sanction Russia three years ago—and to keep doing so. By “we,” I mean the Americans, the Europeans, the Canadians, the Japanese, and many others. Thank you to…

Ukraine is Europe! We stand by Ukraine. We will step up our support to Ukraine so that they can continue to fight back the agressor. Today, it became clear that the free world needs a new leader. It’s up to us, Europeans, to take this challenge.

Finland stands with the people and the people’s right to choose. In Ukraine, people have chosen freedom. We stand by Ukraine. 🇫🇮🇺🇦

We stand by Ukraine in their fair struggle for a just and lasting peace. 🇺🇦🇳🇴

Thank you for your support.
