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...

"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".

Not much you can do in Europe, but if you happen to have a Disney+ subscription: now is the time to cancel it (ABC that pulled Jimmy Kimmel owns the Walt Disney company). Trump's words, after Kimmel and Stephen Colbert were pulled: "That leaves Jimmy [Fallon] and Seth [Meyers]". Free speech no more.

At my university @vuamsterdam.bsky.social AI adoption is taken for granted, and everything seems geared towards "responsible AI adoption". There are questions to test your "AI literacy" that just *assume* that AI usage is beneficial in teaching. All very worrisome. vu.nl/nl/onderwijs...

Below some basic advice for a future government of the Netherlands, that is if we ever obtain a government again. Might also work as a path moving forward for other governments, international disputes etc. Basic stuff you'd think. You'd think.

Today @n41c0.bsky.social defended his PhD thesis, and what a wonderful defense it was! So very proud. Congrats Nico, you did it! 🎉👍🎊🕶️

Finally the Version of Record of our paper "Criterion placement threatens the construct validity of neural measures of consciousness" is out in @elife.bsky.social as *fundamental* and *compelling*!

usage of the word "epistemic" in top 20 philosophy journals over the last 40 years 📈. I rest my case.

But this seems to detract from the idea that the interaction itself may shape / generate information? In figure ground segregation for example, the interaction between a category selective region and a V1-like region may together resolve what is in the image. Similar for PFC and visual cortex.

There is exact data on this actually. It's in my slides.

OK let's see how chatGPT-4 is doing on reasoning.
Hmm, it can't even identify a Modus Tollens. AI is indeed so humanlike, one might even say it could be conscious 😉😂😂😂.

This is great I love this (my two favorite subjects in one study)! Having done a bit of Kanizsa research myself, if you ever consider a follow-up I would recommend a control that has the same support ratio but not the illusion, as in the example below. Not a criticism, I love your study!

But Jorge, are you implying that different mechanisms are involved in hallucination and perception? They seem to clearly operate on the same continuum, where it's the relative weighting of prior to evidence that determines whether the man in the street calls something perception or hallucination.

I think you mean intensional. But the distinction seems naive given what we know about the visual system and perception. The visual system is deeply recurrent and uses what you call 'conceptual' information to perceive: figure-ground segregation, what constitutes an object etc. Many examples of this

I won our faculty's Open Science Award yesterday for the dissemination of the ADAM decoding toolbox for MVPA in EEG. Thanks to the selection committee @vuamsterdam.bsky.social!

Interesting interaction: scientists seem to more often consider themselves reductionists than philosophers. I had thought this, but I'm curious about why others think this might be the case. Would love to hear your thoughts!
