i wrote a paper on two senses of medium independence: the haugeland sense & the garson sense. the haugeland sense is like putnam's multiple realizability & the garson sense is like piccinini's medium independence. they are different and the difference matters onlinelibrary.wiley.com/doi/abs/10.1...

Very excited about this work looking at the emergent mechanisms that vision language models use to perform structured visual processing, mirroring a computational strategy (visual indexing) proposed in cognitive science, but here learned by VLMs. Check out the paper/thread for more details!

Title page of our paper: "Bears, all bears, and some bears. Language Constraints on Language Models' Inductive Inferences"

β€œAll bears have a property”, β€œSome bears have a property”, β€œBears have a property” are different in terms of how the property is generalized to a specific bear – a great example of how language constrains thought!

This holds for kids, adults, and according to our new work, (V)LMs! 🧡

I’m not saying we should ignore the biological details. I think the details matter a lot for implementing the right functions. But if you think biology matters beyond that, just give me a *biological* property that reliably distinguishes conscious from unconscious states.

Dopamine neurons signal default behavior to reinforce habits Movement-sensing neurons in the striatum influence a mouse’s choice of action by favoring routine behaviors.

A non-value-based system in the brain automates decision-making and frees up cognitive resources for other tasks, a new study in mice suggests.
