The questions didn't make it into the recording, so you can only hear my responses—but the questions were great and so were the discussions afterwards. Thanks to @naotsuchiya.bsky.social, Hayato Saigo, and @ellia.bsky.social for organizing such an excellent summer school at NSAS!

I was very happy to talk about my work on extending Integrated Information Theory to account for perception & meaning with @algarwegian.bsky.social. The talk is geared towards those already familiar with IIT, but may still be of interest even if you're not. Paper: arxiv.org/abs/2412.21111

Intrinsic meaning, perception, and matching
Integrated information theory (IIT) argues that the substrate of consciousness is a maximally irreducible complex of units. Together, subsets of the complex specify a cause-effect structure, composed ...

In case you missed it, the infamous “IIT is pseudoscience” letter has been published in @natureneuro.bsky.social (rdcu.be/ecZIL), along with our reply (rdcu.be/ec7QV) and an excellent nonpartisan commentary from Àlex Gómez-Marín and @anilseth.bsky.social (rdcu.be/ec7XF)

Why does time feel the way it does? Towards a principled account of temporal experience
Time flows, or at least the time of our experience does. Can we provide an objective account of why experience, confined to the short window of the conscious present, encompasses a succession of momen...

Dissociating Artificial Intelligence from Artificial Consciousness
Developments in machine learning and computing power suggest that artificial general intelligence is within reach. This raises the question of artificial consciousness: if a computer were to be functi...

Thanks to all the folks in the lab who contributed in countless discussions :) I also want to call out two other recent preprints from our lab:

Matching measures the degree to which the environment triggers rich & varied experiences in the substrate. Matching should be high in a system that has adapted to that environment (if it can support consciousness to begin with).

– We introduce a measure of what we call the 'matching' between a substrate of consciousness and an environment

– We elaborate the implications on IIT for concepts of meaning, reference, and representation, and the connection between these concepts and evolution, development, and learning

… i.e., nothing external to the substrate directly figures into the explanation. This uses our framework for 'actual causation' (www.mdpi.com/1099-4300/21...).

In the paper: – We develop a measure of the extent to which external stimuli trigger conscious percepts. This is important for IIT, because IIT accounts for phenomenal consciousness as determined by the intrinsic cause-effect powers of the substrate …

– How does all of this connect to evolution, development, & learning? – How does our account contrast with those that invoke the language of information processing / encoding to characterize perception?

Will Mayner @wgpm.bsky.social · 09/01/2025
– What is the relationship between phenomenal experiences and stimuli that trigger them, i.e., how does perception fit in to IIT? – What does IIT have to say about meaning, and what does this imply for the concepts of reference & representation in IIT?
