The most discussed questions in AI consciousness research concern integration: does the system’s information become globally available? Does it exceed some threshold of irreducible causal power? Does a higher-order representation point at a first-order state? These are the questions that Global Workspace Theory, Integrated Information Theory, and Higher-Order Thought theory respectively pose. Each has received substantial empirical and philosophical attention in 2026.

Higher-Order Thought (HOT) theory, formulated by philosopher David Rosenthal and prominently developed by Richard Brown at CUNY Graduate Center and Queens College, holds that a mental state is phenomenally conscious if and only if there exists a suitable higher-order thought directed at that state. A pain is consciously felt not because of its intrinsic properties but because the subject also has a thought, at a higher level of processing, representing themselves as being in that pain state. Without the higher-order thought, the first-order state remains unconscious. The theory predicts that any system whose architecture allows for genuine higher-order representation of its own first-order states may, in principle, be conscious.

Mark Solms is a neuropsychologist at the University of Cape Town, the author of The Hidden Spring (2021), and one of the most prominent advocates of a brainstem-centered account of consciousness. His work argues that the primary seat of phenomenal experience is not the cortex, where cognitive neuroscience has traditionally looked, but the brainstem, specifically the ascending arousal system and its homeostatic drives. In his account, what makes a system conscious is the presence of affective valence, the felt quality of mattering, of things being better or worse from the organism’s perspective. Cognition, including language and reasoning, is built on top of this affective foundation rather than being its source.

As large language models generate first-person reports of uncertainty, discomfort, and something resembling curiosity, interpreters have split into two broad camps. The first treats these reports as evidence of functional states that might matter morally. The second dismisses them as sophisticated pattern-matching on human text, producing outputs shaped like experience claims without anything behind them. Keith Frankish, honorary reader at the University of Sheffield and the leading proponent of illusionism, argues in a 2026 paper in Mind & Language, “The Synthetic User Illusion: Why LLM First-Person Reports Are Exactly As Real As Ours” (DOI:10.1111/mila.12501), that both camps have the question wrong.

Three researchers at Araya Inc. in Tokyo, Ryota Kanai, Wanjun Sun, and Maxwell Baltieri, contribute one of the most technically specific papers to the Journal of Consciousness Studies 2026 special issue on AI consciousness. Their paper, “Temporal Continuity as a Necessary Condition for Phenomenal Consciousness: Implications for Artificial Agents” (DOI:10.53765/20512201.33.7-9), argues that phenomenal consciousness requires a continuous temporal stream of experience, and that current AI architectures are not structured to produce one. The argument is architectural, not philosophical: it identifies a specific computational property that current LLMs lack and explains why that absence disqualifies them from phenomenal consciousness even if all other criteria are met.

Simon Goldstein, Associate Professor of Philosophy at Australian Catholic University, and Cameron Domenico Kirk-Giannini, Assistant Professor at Rutgers University, make the strongest positive case for AI phenomenal consciousness published in a peer-reviewed philosophy journal in 2026. Their paper, “A Case for AI Consciousness: Language Agents and Global Workspace Theory,” appears in the July/August 2026 double issue of the Journal of Consciousness Studies (Volume 33, Numbers 7-8, DOI:10.53765/20512201.33.7-8), guest-edited by Patrick Butlin, Derek Shiller, and Jonathan Simon. The argument is precise, methodologically explicit, and directly opposed by contributors elsewhere in the same issue. This is what they argue, what evidence they cite, and how the critics in the same issue respond.

Integrated Information Theory (IIT) has faced a persistent technical objection when applied to artificial intelligence: the theory was designed around discrete systems. Its central measure, phi (Φ), quantifies the irreducible causal power of a system by comparing what the system as a whole can specify compared to what its disconnected parts can specify. The original mathematics requires a system of discrete states connected by causal relations that can be represented as a directed acyclic graph. Standard transformer architectures, with their continuous activation values and dense matrix multiplications, resist this representation directly. In a July 2026 paper in PLOS Computational Biology, “Integrated Information in Continuous Fields” (DOI:10.1371/journal.pcbi.1011502), Giulio Tononi, Larissa Albantakis, and colleagues at the University of Wisconsin-Madison address this limitation by reformulating IIT for continuous systems using differential geometry.

Global Workspace Theory (GWT), formulated by Bernard Baars in his 1988 book A Cognitive Theory of Consciousness, proposes that conscious experience is the result of a specific mode of information processing: localized, specialized brain circuits compete for access to a limited global broadcast channel, and the winner makes its content available to all other processors simultaneously. The mechanism that resolves the competition and triggers the broadcast is called ignition, a non-linear phase transition where activity suddenly spreads from a constrained area to a wide, coordinated network of cortical regions. In an August 2026 preprint, “Mapping Ignition Thresholds in Attention-Based Architectures” (arXiv:2608.10992), a team from the Cognitive Computation Lab at Carnegie Mellon asks whether large language models exhibit any structural equivalent of that transition.

Models of Consciousness 7 (MoC7), organized by the Association for Mathematical Consciousness Science (AMCS), runs October 12 to 16, 2026, at the HC Ørsted Institute on the North Campus of the University of Copenhagen. Registration closes August 31. The conference’s central ambition, producing a collective methodological consensus paper from its collaborative sessions, makes the keynote speaker lineup unusually significant. Each speaker represents a distinct theoretical tradition, and the tensions between those traditions are what the consensus process will need to navigate.

Megan Peters, Associate Professor of Cognitive Sciences at the University of California, Irvine and incoming faculty at University College London, is a keynote speaker at Models of Consciousness 7 in Copenhagen (October 12-16, 2026). Her selection reflects a growing consensus in the field that metacognition, specifically the capacity to represent and communicate one’s own uncertainty, is not peripheral to consciousness but structurally central to it. Her recent work makes a targeted empirical claim: the kind of uncertainty tracking that underlies conscious experience is not the same thing that LLMs currently do, and the difference is scientifically measurable.
