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?

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?

That would be a positive outcome

Same. This was actually quite good.

My god you're useless.

Just sign the damn petition Edwin!

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.

Typical 😂
