But "Alternatively, in higher-order representation of a representation (HOROR) theory, the relevant higher-order state in PFC itself is phenomenally conscious."

For some HOTs, "consciousness is β€˜jointly determined’ by concurrent activity in the higher-order areas and areas that maintain the lower-order representations."

Understanding the Higher-Order Approach to Consciousness The higher-order theory (HOT) of consciousness has often been misunderstood by critics. Here, we clarify its position on several issues, and distinguish it from other views, such as the global workspa...

My understanding is that yes, some HOTs argue that contents are re-represented in the higher-order model and only that model is important for consciousness.

How do we balance external attention to the outside world and internal attention to our thoughts & memories?

We review evidence that external and internal attention can compete, unfold concurrently, or cooperate!

Loved working on this with @samversc.bsky.social & @tobiasegner.bsky.social!

Objects warp space in our mind, and events warp time in our mind. @samiyousif.bsky.social and I teamed up to review the work in these two literatures and suggest that there may be deep connections across them (with analogous influences of objects on space and events on time).

UK business secretary urges EU to stop β€˜putting up barriers’ Comments by Peter Kyle come on Brussels trip aimed at securing British access to β€˜Made in Europe’ scheme

🚨🚨 Major irony warning:

The UK decision to depart from the EU in the "hard" way opting for the TCA was the most severe barrier to EU trade that could be imposed.

Now live with it or renegotiate the basic terms of this framework. #brexit

This is great from the @athenaakrami.bsky.social lab β€” hippocampus is required for unsupervised statistical learning, and dCA1 populations split into subspaces for sensory features vs abstract rules. Elegant optogenetic + recording approach.

This really stuck out - the loans are currently unrepayable for the vast majority of students. This means you pay for the entire 30 years it takes before it gets wiped, and so you end up paying maybe twice what you borrowed. This is an insane burden to place on students

An ICE agent shot and killed Ruben Ray Martinez, a US citizen and San Antonio resident, in March 2025. Then ICE and the Texas Department of Public Safety covered it up. He was 23 years old. I am calling for a full investigation into this shooting, including why there was an 8-month cover up.

Producing more while understanding less with large language models Many scientists are enthusiastic about the potentials of 'Artificial Intelligence' (AI) for research. We recently examined the vision of β€˜AI Surrogates’ [1]: computer models [including but not limited to large language models (LLMs)] designed to simulate human participants for the purpose of generating knowledge about human cognition and behavior. Some scientists believe that AI Surrogates can improve the generalizability of cognitive science: first, by simulating diverse populations that are not readily accessible, overcoming the field’s overreliance on Western, Educated, Industrialized, Rich, Democratic (WEIRD) samples; and second, by enabling researchers to quickly and cheaply explore vast experimental design spaces, expanding the diversity of situations that can be probed experimentally.

No surprise there. Ru wants Ukraine to surrender but can’t compel them. Ukraine isn’t losing on the battlefield and they don’t want to submit to Ru occupation. The US is not an honest broker but trying to help Ru achieve its goals diplomatically. US has stopped aid to Ukr so it has little leverage.

Why does a billionaire living in Monaco think the UK has been β€˜colonised’ by migrants? | The News Agents Jim Ratcliffe, believed to be the seventh-richest Brit in the world, has faced backlash for claims the UK has been β€œcolonised” by migrants. Has this language been normalised in Britain?

"I have a hunch more Brits would say they prefer people, immigrants or not, who pay their taxes, rather than billionaires who bugger off to Monaco and don’t," says
Emily Maitlis.

Jim Ratcliffe, she adds, is "out of his depth" with 'colonisation' claims
