I assume that [phenomenal] consciousness is a property physical processes can have, and that it involves pre-reflective auto-sensitivity (PRAS), which is related to the much-discussed pre-reflective self-consciousness [3,4]. I then argue that PRAS requires conscious processes to be directly and causally sensitive to their own inner causation as such, and not merely to their own trajectories of physical states as ordinarily understood. That causal sensitivity is therefore metacausation. Metacausation here is where instances of causation are themselves, directly and in their own right, causes or effects. Metacausation (aka higher-order causation) is rarely discussed at all, and has apparently not previously been linked to consciousness. But the proposal is yet more radical as I merely use "causation" to mean microphysical dynamism. I assume (anti-Humeanly) that the universe's law-governed unfolding is a dynamism irreducible to sheer regular patterning over spacetime of familiar physical quantities (masses, charges, fields, curvatures, etc.). Furthermore, I strongly reify dynamism: spatiotemporally specific instances of it are a ``new'' realm of fundamental physical quantities, themselves dynamically interacting in their own right with other quantities (familiar or new). That dynamic interaction is a new level of dynamism, namely metadynamism, with its own laws explicitly mentioning dynamism instances. As causation is just dynamism, metacausation is metadynamism. The poster summarizes the arguments (revising earlier versions [1,2]) and sketches initial formalization steps for metadynamism. It also indicates how metadynamism might be co-opted to enrich other consciousness theories, notably IIT and Orch-OR.

Michael Silberstein - Quantum mechanics and the consistency of conscious experience
One in a series of talks from the 2019 Models of Consciousness conference. Michael Silberstein

We discuss the implications for the determinateness and intersubjective consistency of conscious experience in two gedanken experiments from quantum mechanics (QM). In particular, we discuss Wigner's friend and the delayed choice quantum eraser experiment with a twist. These are both cases (experiments) where quantum phenomena, or at least allegedly possible quantum phenomena/experiments, and the content/ecacy of conscious experience seem to bear on one another. We discuss why these two cases raise concerns for the determinateness and intersubjective consistency of conscious experience. We outline a 4D-global constraint-based approach to explanation in general and for QM in particular that resolves any such concerns without having to invoke metaphysical quietism (as with pragmatic accounts of QM), objective collapse mechanisms or subjective collapse. In short, we provide an account of QM free from any concerns associated with either the standard formalism or relative-state formalism, an account that yields a single 4D block universe with determinate and intersubjectively consistent conscious experience for all conscious agents.
Essentially the mystery in both experiments is caused by a dynamical/causal view of QM, e.g., time-evolved states in Hilbert space, and as we show this mystery can be avoided by a spatiotemporal, constraint-based view of QM, e.g., path integral calculation of probability amplitudes using future boundary conditions. What will become clear is that rather than furiously seeking some way to make dubious deep connections between quantum physics and conscious experience, the kinds of 4D adynamical global constraints that are fundamental to both classical and quantum physics and the relationship between them, also constrain conscious experience. That is, physics properly understood, already is psychology.
