Anyone who takes Huberman too seriously might want to complete my Metascience course assignment where you get to dive into his understanding of statistics and his confirmation bias: daniellakens.blogspot.com/20…

Starting tomorrow, and every Monday thereafter, full length episodes of the Huberman Lab podcast will be released on @X. Thank you for your interest in science!

I really enjoyed reading this world view in @Nature about the importance of exploratory research in the social sciences by @BalazsAczel and am wondering what people think. Do you generally agree with his point? nature.com/articles/d41586-0…

Time for the World Cup slalom in Levi, which features a long flat section. Remember to 'extend with rock skis forward' in this section to achieve the best race time! ⛷️⛷️⛷️

It is extremely sad to see some qualitative resesrchers take the epistemologicl view that truth is crested, and qualitative resesrch is in principle not replicable. These voices should be severely criticized within the qualitative research community, and preferably driven out.

🚨New pub out now! 🚨In this study we showed that performance level moderated learners’ sensitivity to reward-prediction errors. For some insights into what this might mean for instructors interested in motor skill acquisition, grab a free copy here 👇

Time for a thread on our new preprint on exploratory analyses! This paper was started by Max Ditroilo during his sabbatical at my lab. It started from the observation that exploratory research is often not openly reported. How can we improve this? sportrxiv.org/index.php/serv… >

As my PhD comes to an end, I want to acknowledge the methods books that have been instrumental in my journey. *Missing from the list is statistical rethinking
This book by Dale Barr has also been exceptionally helpful:

We've received great and valuable inputs on our new preprint about using reinforcement learning to improve sports training ⛷️🏌️♀️ 🎾⚽️ - Thank you! We are still seeking feedback and comments before submitting it to a journal. Please retweet!

Do elite athletes benefit from instruction and feedback from a coach? In our new preprint (biorxiv.org/content/10.1101/…), we tested whether slalom racers learn to make better strategy choices and therefore perform better with reinforcement learning than with instruction-based learning

⛷️If you're a coach aiming to help your skiers perform better in slalom, our new preprint might be of interest: biorxiv.org/content/10.1101/…. In this study, 98 alpine skiers (13/98 ranked in the top 100 in the world 🏅) tested four strategies (panel b) (1/4)

Based on our findings, reinforcement learning appears to be an effective training strategy for skilled performers. We believe that reinforcement learning can serve as a valuable supplement to traditional instruction. More on this in the discussion.

We have also analyzed the ranking and performance of each strategy. More details on this can be found in the paper. In summary, we found significant differences in race times between the strategies.

What information guided the strategy decisions in the two learning groups? We found that both learning groups’ decisions could be accounted for by a ’win-stay, lose-shift’ heuristic. The difference between the learning groups was not statistically significant, however

We predicted strategy choice could explain our findings, but reinforcement learning did not show a greater probability of selecting the theoretically best strategy or each skier's estimated best strategy. However, they incurred lower costs for their suboptimal strategies
