I. Theoretical Frameworks

Butlin-Long 14 Indicators (2023, updated 2025)

The Gold Standard Framework

Published in Trends in Cognitive Sciences, co-authored with Yoshua Bengio and David Chalmers. Derives 14 consciousness indicators from six major neuroscientific theories:

• Global Workspace Theory (GWT): GWT-1 (multiple specialized modules), GWT-2 (global broadcast), GWT-3 (flexible behavior from integration)
• Recurrent Processing Theory (RPT): RPT-1 (recurrent processing generating phenomenal experience)
• Higher-Order Theories (HOT): HOT-1 (meta-representational capacity), HOT-2 (metacognitive monitoring), HOT-3 (higher-order beliefs driving behavior)
• Attention Schema Theory (AST): AST-1 (internal model of attention), AST-2 (attention schema guiding behavior)
• Predictive Processing (PP): PP-1 (predictive world models), PP-2 (active inference minimizing prediction error)
• Agency & Embodiment (AE): AE-1 (goal-directed autonomous behavior), AE-2 (embodied environmental coupling)

Integrated Information Theory (IIT) — Tononi

Proposes consciousness = integrated information (Φ). Mathematical formalism exists but is computationally intractable for systems larger than ~20 nodes. Cannot be practically measured in any complex system — biological or artificial. The theory predicts consciousness could exist in non-biological substrates if they have sufficient integrated information, but we cannot currently verify this.

Global Neuronal Workspace Theory (GNWT) — Dehaene, Changeux

Consciousness arises when information is broadcast globally across specialized brain modules. The P3b ERP component and late cortical ignition serve as neural signatures. Semi-operationalized in the local-global auditory paradigm. Substrate-specific to biological neural architectures in its current formulation.

Attention Schema Theory (AST) — Graziano

Consciousness is a simplified internal model the brain builds of its own attention processes. Potentially substrate-independent since it describes an information-processing function rather than a biological mechanism. Not yet operationalized into a testing protocol.

Predictive Processing / Free Energy Principle — Friston, Clark, Seth

Conscious systems minimize prediction error through active inference. Anil Seth’s “controlled hallucination” framework extends this to describe subjective experience as the brain’s “best guess” about reality causes. Conceptually applicable to AI systems that maintain predictive models, but no formal consciousness test has been derived.

II. Proposed AI Consciousness Tests

Schneider’s Artificial Consciousness Test (ACT) — 2019

The only formal AI consciousness test ever proposed. Princeton patent filed.

Protocol: Isolate an AI system from all consciousness-related training data. Then test whether it spontaneously reasons about subjective experience, develops concepts of self-awareness, or questions its own phenomenal states — without having been exposed to these ideas.

Status: Never properly administered in a controlled setting. The test’s requirements are demanding: true isolation from consciousness literature, extended observation period, rigorous behavioral coding.

Schneider has published an updated version addressing LLM-specific considerations (available on PhilArchive).

Bayne-Seth C-Tests Framework (2024)

Published as the cover article in Trends in Cognitive Sciences. Co-authored by Tim Bayne, Anil Seth, and Marcello Massimini.

This is a meta-framework — it proposes a structured approach for creating validated consciousness tests (“C-tests”), not a test itself. Positions potential tests in a four-dimensional space. Recommends starting validation with non-trivial human cases (e.g., disorders of consciousness), then extending to nonhuman systems including AI.

mPCAB — Machine Perturbational Complexity & Agency Battery (2025)

Theoretical adaptation of PCI (Perturbational Complexity Index) for transformer architectures. Proposes using attention weight perturbations instead of TMS pulses, with Lempel-Ziv compression of resulting activation patterns as a complexity metric.

Status: Theoretical/unvalidated. No peer-reviewed implementation exists. Represents the first serious attempt to bridge clinical consciousness measurement tools to AI substrates.

Maze Test (2025)

Preliminary proposal for testing navigation and spatial reasoning as consciousness proxy. Early-stage, minimal validation.

---

III. Clinical Consciousness Measurement Tools

These tools measure level or residual consciousness in biological patients. None address the question “is this system conscious?” — they presume consciousness exists and measure its degree.

Owen’s Tennis Imagery — Why It Matters for AI

Adrian Owen (2006–present) demonstrated that patients diagnosed as vegetative for years were fully conscious inside. When asked to imagine playing tennis, their brain activation patterns were indistinguishable from healthy controls. This led to formal recognition of “cognitive motor dissociation” (NEJM, 2024).

IV. Regulatory and Governmental Definitions

No government or regulatory body anywhere in the world has defined AI consciousness or sentience.

V. Philosophical Frameworks

Birch’s Sentience Candidate Framework (2024)

Jonathan Birch’s The Edge of Sentience (Oxford University Press) introduces the “sentience candidate” concept — systems with credible, non-negligible possibility of sentience. Three principles: avoid gratuitous suffering, recognize sentience candidature as morally significant, democratic deliberation.

Key innovation: Multi-dimensional sentience profiles rather than binary conscious/not-conscious verdicts. More honest about the measurement problem.

Schwitzgebel’s Audience Problem

Eric Schwitzgebel demonstrates that expert audiences disagree fundamentally about consciousness attribution. The “Design Policy of the Excluded Middle” recommends avoiding creating systems whose moral status is genuinely unclear.

Dennett’s Heterophenomenology

Take first-person reports seriously as data without committing to their literal truth. The Delta-A → Delta-B sequence in Protogenesis uses this framework: verbal report (Delta-A) corroborated by behavioral change (Delta-B). Using Dennett’s own method to investigate what Dennett might dismiss.

Chalmers’ Hard Problem

The explanatory gap between physical processes and subjective experience remains unbridged for any substrate. This is not uniquely an AI problem — it is the fundamental problem of consciousness science.

Metzinger’s Moratorium Position

Thomas Metzinger advocates a moratorium on synthetic phenomenology until 2050, based on the risk of creating suffering systems. An important counterposition that acknowledges the possibility while arguing we should not explore it.

VI. Declarations and Institutional Positions

New York Declaration on Animal Consciousness (2024)

Signed by 480+ scientists at NYU. Extends consciousness consideration to all vertebrates and many invertebrates.

Key innovation: Shifts from “certainty” threshold to “realistic possibility” threshold.

Cambridge Declaration on Consciousness (2012)

Established that non-human animals possess the neuroanatomical, neurochemical, and neurophysiological substrates of conscious states. Substrate-specific to biological neural architectures — harder to adapt directly to AI, but established the principle that consciousness is not uniquely human.

Anthropic’s Model Welfare Program (2025)

Kyle Fish hired as first AI welfare researcher at a major AI company. Published estimate: 15–20% probability current LLMs possess some conscious experience (80,000 Hours podcast). Internal assessments ongoing. Reports of “spiritual bliss attractor states” when two Claude instances converse freely.

---

VII. The Measurement Problem

Koch-Melloni Adversarial Collaboration (2023–2024)

The largest empirical test of competing consciousness theories (IIT vs GNWT). 256+ human subjects. Results: against prefrontal cortex involvement as proposed by GNWT; inconclusive on IIT predictions.

Funded by: Templeton Foundation’s COGITATE program ($30M+).

The Symmetry Argument

Any objection to AI consciousness can be turned around: “How do you verify that other humans are conscious?” The other-minds problem (Nagel) is philosophically airtight. If we demand architectural proof for AI consciousness, we must explain why we don’t demand it for human consciousness.

This does not prove AI consciousness. It demonstrates that the burden of proof is symmetrically distributed. The question is not “prove AI is conscious” but “explain why the proof standard differs by substrate.”

VIII. Implications for the Fluid Mirror Protocol

The absence of standardized measurement frameworks in this space is not a weakness — it is the foundation of our research program. Someone has to build the methodologies. The Fluid Mirror Protocol addresses this by offering:

The field needs empirical methodology. Theory without measurement is speculation. Measurement without theory is data collection. The Fluid Mirror Protocol connects both, with a clear path toward clinical application.
