There is no eye tracking in this paper, just pupil size and the code is specifically about how to provide the biofeedback on pupil size. This is not difficult to set up once you have an eye tracker. I don't think they have "built" an eye tracker but ok. Also, where are the analysis scripts?

Johannes Fahrenfort @fahrenfort.bsky.social · 6d

Even if this is true, I think it's stupid. It's not a high-tech thing to provide feedback on pupil size, everybody can do this. The work is not the code here, the work is doing something useful/marketable with it. No mention of the analysis scripts either.

Also, where is the analysis code? Surely there is a lot more to this paper than just the biofeedback algorithm?

Who thinks this is an acceptable statement about Code Availability given the move towards Open Science? Are you out of your mind @ethz.ch? Today is 2025, not 2005. I'm also surprised that @natcomms.nature.com accepts such a statement. It is ridiculous really. Paper here: doi.org/10.1038/s414...

Code availability: The code of the pupil-based biofeedback algorithm cannot be made publicly available since it is proprietary software of ETHZurich and cannot be shared beyond the detailed description of the algorithm given in the methods section. However, researchers interested in verifying and reproducing our results can do so on location in a secured environment at the Neural Control of Movement Laboratory, ETH Zurich, upon signing a confidentiality agreement.

That would be a positive outcome

Same. This was actually quite good.

It's looking increasingly less likely that AI will take over the world and replace humanity in the process. Maybe GPT-6?

The EU wants to ban words like "burger" for veggie burgers. What are we supposed to call it then? Veggie thing formerly known as burger? Go do something useful with your time idiots, this is why the UK left. Please sign petition and stop the meat lobby.

Sure, but I've also seen cases like this in published work, so still a bit tricky. But I agree it's understandable in pre-print stage.

1/ Why are we so easily distracted? 🧠 In our new EEG preprint w/ Henry Jones, @monicarosenb.bsky.social and @edvogel.bsky.social we show that distractibility is associated w/ reduced neural connectivity — and can be predicted from EEG with ~80% accuracy using machine learning.

This is a dumb take. Students already know how to use AI. Regardless, we need to teach them *about* AI, and they need to learn fundamental skills (find sources, reason, write, program) *without* AI. Only once such core skills are acquired can they even evaluate AI output.

If you don’t teach your students how to use AI, you’re doing them a huge disservice because they won’t have jobs in the future.

If you don’t teach your students your subject, you’re not doing your job.

If you teach your students to ask AI first, you’re ensuring they’ll never be *needed* for any job.

You’re also guaranteeing that knowledge of your subject slowly dies.

Asking ChatGPT is gaining neither knowledge nor skills.

Simulations are fun! Especially with the right tools😉.
@willenjoy.bsky.social and I (with support from Mina Jamshidi) made a toolbox for simulating EEG/MEG data
meegsim.readthedocs.io
I put together a quick simulation using it for this short clip. Took me 10 minutes (no, really!)

This all sounds great, but I think it starts with requiring that people power their studies to detect Null effects. Pick a SESOI and do power analysis for a TOST rather than NHST. Publication will be much easier for such results whichever way the chip falls. Or go Bayes.

A method for capturing neuronal activity using fMRI excited the neuroimaging field but couldn’t be replicated. Today, the authors of the original paper retracted their work.
