Most of you know @suryagayet.bsky.social as a successful visual-attention researcher. But he also had an active #music career as a #rap artist. And like Jay-Z before him, he has briefly come out of retirement with a new album. Check it out—it's very good! 🎤🎶 open.spotify.com/album/7HrnAB...

it is time to make my biyearly post because I put a preprint out🎉🍾😀. we (w/ @svangaal.bsky.social, Z. van den Hurk, @timostein.bsky.social & @fahrenfort.bsky.social) attempted to replicate a classic unconscious priming study by Vorberg et al. (2003) using a single-subject Bayesian approach.

Great overview conceptualizing approaches for studying sensory conscious perception👏. I, myself, had research experience with both subjective and objective approaches, but it was nice to learn the great landscape and where I land. Table 1 is especially informative.
Pre-print 🎉 "Subjective and objective approaches in the study of conscious perception" will be a chapter in www.horizon-minds.com. We explain that subjective and objective are poorly defined constructs and provide a taxonomy.

I know we all collectively frown upon keeping browser tabs open. But I swear there are certain tasks that I regularly do just bec that tab is open and that wouldn't happen otherwise. Yes, that's only true for a few of them. But the remaining few hundred are there in supporting roles, cheering me on.

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.

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.

"Next" is such a confusing word. If "next" means "coming immediately after the time of writing or speaking", why isn't "next Friday" the same as "upcoming Friday"? Why is there this strange interaction with the week in which the day takes place? I have just stopped using the word "next".

How does the brain decide? 🧠
Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.
After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.
