What functional or cognitive roles are associated with consciousness?

DIT makes a positive, specific functional claim rather than a vague gesture: the core asserted role of consciousness is the flexible integration of feedforward sensory content with top-down/contextual information across cortico-thalamo-cortical loops. From this it names concrete functions that consciousness enables — context-dependent perception, perceptual detection and report, and learning/memory formation — and explicitly contrasts them with unconscious processing, which it restricts to local feedforward computation lacking this global, context-integrating capacity. This satisfies the yes-bar because it specifies WHICH functions (context-integration, perceptual detection/report, memory) require consciousness, not merely that consciousness is 'useful.' It does not need to address phenomenal experience here; the question is purely functional.

Key evidence: Aru, Suzuki & Larkum (2020) and Bachmann, Suzuki & Aru (2020) frame consciousness as the coupling of apical (contextual) and somatic (feedforward) compartments that enables content-plus-context integration, with unconscious processing reduced to local feedforward computation — yielding named functions (context-dependent perception, detection/report, memory formation).

Question 5 asks which cognitive/psychological functions are enabled by consciousness, and the YES-bar requires a positive, specific account of consciousness's functional role rather than a vague "it's useful" claim. Mansell's PCT account does exactly this: it ties consciousness/awareness to a delimited and specific set of functions — reorganization (acquiring new control structures and new reference values/goals through error-driven structural change), detecting and resolving conflict between control systems, "going up a level" to gain perspective on conflicting goals, directing attention to persistent error, imagination (running perceptual loops offline to plan and test references without acting), regulating the integration rate of novel information, and at the tertiary level language, logic, and symbolic reasoning via a propositional system. Critically, it draws a positive contrast: consciousness handles the novel, conflicting, and not-yet-controlled, while routine control proceeds automatically — which is a substantive functional division of labor, not a gesture. The theory's central weakness (the hard problem of why reorganization is accompanied by experience) bears on other questions, not on the WHICH-functions content this question demands.

Key evidence: Mansell (2022, Psychological Review, "An integrative control theory perspective on consciousness") assigns consciousness specific roles — regulating reorganization, conflict resolution, attention to error, imagination/offline planning, integration of novel information, and tertiary symbolic reasoning/language/logic.

Question 5 asks only which cognitive/psychological functions are enabled by consciousness, and AST gives a specific, positive answer rather than a vague "it's useful" gesture. On AST, awareness IS the attention schema, and Graziano/Webb explicitly tie that model to named functions: (1) improved endogenous control of one's own attention (the schema as a control model), (2) social cognition / theory of mind via attributing attention and awareness to other agents, and (3) self-attribution of consciousness underwriting introspective report and certainty about having experience, plus binding/integration of information into a coherent reportable representation. These are concrete functional roles, and the control-of-attention claim is mechanistically operationalized and empirically tested in Wilterson & Graziano (2021), where a neural-network agent uses a descriptive attention-schema model to control visuospatial attention. The hard-problem objection in the standard targets the "why is there something it is like" question, which is a different question; it does not undercut AST's explicit, specific account of function.

Key evidence: Wilterson & Graziano (2021, PNAS 118(33)) show a neural-network agent using a descriptive attention-schema model to improve control of visuospatial attention, directly instantiating the named function "consciousness/awareness enables endogenous attention control."

The yes-bar requires the theory to specify WHICH cognitive/psychological functions are enabled by consciousness, with a positive specific account rather than a vague "useful" claim. Orch OR, as actually formulated by Penrose and Hameroff, makes exactly such specific claims: consciousness enables non-computable mathematical understanding/insight (the explicit core of the Penrose-Lucas/Gödel argument in Shadows of the Mind and The Emperor's New Mind) and genuine free will/volition (Hameroff 2012, "How quantum brain biology can rescue conscious free will"). These are named, particular functions tied to the proposed mechanism (non-computable OR collapse selecting states), not a generic gesture. The strict standard for THIS question asks which functions, not whether the mechanism is correct, so the heavily contested validity of the Gödel argument and decoherence objections go to soundness, not to whether the theory specifies a functional role.

Key evidence: Penrose's Gödel/Penrose-Lucas argument (The Emperor's New Mind 1989; Shadows of the Mind 1994) explicitly identifies non-computable mathematical understanding as a function consciousness enables, and Hameroff (2012, PMC3470100) explicitly argues Orch OR enables conscious free will — two named, specific functions.

The yes-bar asks for a positive, specific account of WHICH cognitive/psychological functions consciousness enables. RPT, as formulated by Lamme, does exactly this for the phenomenal (localized recurrent) stage: it assigns perceptual integration/grouping — binding features into figures and scene segmentation — and, centrally in his 2018 view, the induction of recurrent-processing-dependent synaptic plasticity, i.e. learning and memory (conscious recurrent processing makes a stimulus more likely to be remembered and to alter the network). RPT also makes a sharp, specific negative claim, denying that attention, working memory, report, and executive access are functions OF phenomenal consciousness (assigning them to separate stage-4/access processing). That combination of named enabled functions (perceptual organization, plasticity/learning) goes beyond a vague "it is useful" gesture and satisfies the bar.

Key evidence: Lamme (2018, Phil. Trans. R. Soc. B 373:20170344) makes recurrent-processing-induced network plasticity (Hebbian, NMDA/calcium-dependent learning and memory) the decisive functional payoff of conscious recurrent processing, alongside the perceptual binding/figure-ground segmentation role from Lamme & Roelfsema (2000).

Question 5 asks which cognitive/psychological functions consciousness enables, and this is GWT's central, self-described explanatory target. GWT does not merely call consciousness "useful": it names specific functions and ties them mechanistically to global broadcasting/ignition — working memory maintenance and manipulation, deliberate decision-making and executive control, voluntary action initiation, metacognition, flexible context-sensitive behavior in novel/ambiguous situations, durable learning, reportability, integration of distributed information, and imposition of a single serial coherent train of thought on a parallel substrate. The mechanism (winning the competition for the limited-capacity workspace and being broadcast back to all processors) is causally linked to why these functions become possible, so this is a HOW/WHY account of function, not just a WHEN/WHERE correlate. The well-known hard-problem objections to GWT concern phenomenal experience (qualia), which is a different question; they do not undercut its account of function.

Key evidence: Baars (1988, 2005) explicitly enumerates conscious involvement in perception, emotion, motivation, learning, working memory, voluntary control and self systems, and Dehaene & Naccache (2001) frame global availability as what enables working memory, report, and flexible deliberate control.

IIT does not merely fail to answer the Function question — it programmatically refuses to. Its central commitment is that consciousness is an intrinsic, irreducible causal property (the maximal Phi-structure), explicitly NOT a function or computation. Tononi and Koch argue that cognitive/psychological capacities like attention, working memory, language, intelligence, and report can be performed by systems (feed-forward networks, digital simulations) that experience "next to nothing," and conversely that a system can have high Phi without performing such functions. The yes-bar requires a positive, specific catalogue of functions consciousness ENABLES (arithmetic, prediction, mental rotation, etc.); IIT supplies the opposite — a principled dissociation of consciousness from function. This is a deliberate anti-functionalist stance, not a gap awaiting future work, so it cannot satisfy a question that asks which functions consciousness enables.

Key evidence: IIT's explicit claim (Tononi & Koch 2015; Koch's consciousness-vs-intelligence plot) that functionally capable systems like AlphaGo/ChatGPT have ~zero Phi and that consciousness is "not a function or computation" — i.e., IIT denies consciousness enables specific cognitive functions.

NPS proper is, by its own proponents' admission, restricted to perceptual phenomenology (color, sound, pitch similarity relations) and is silent on reasoning, memory, executive function, or any cognitive/psychological function. The only functional content comes from importing Northoff's separate TTC/Spatiotemporal Neuroscience framework, which offers "temporo-spatial globalization" as broadcasting/global access. But that is a generic access/integration claim about WHEN cognition becomes conscious, not a positive specification of WHICH functions consciousness enables. Indeed TTC recasts predictive coding, episodic memory, and mind-wandering as already embedded within spatiotemporal dynamics rather than as functions specifically enabled by consciousness, which collapses the distinction the question asks for. There is no commitment naming determinate cognitive operations (e.g. arithmetic, inference, mental rotation) that consciousness makes possible.

Key evidence: The theory description states NPS proper "does not extend to reasoning, memory, or executive functions" and that cognition/function is supplied only by importing the distinct TTC framework, whose contribution is "global access/integration via globalization" — a generic access claim, not a specific functional inventory.

The YES-bar requires a positive, specific account of WHICH cognitive functions consciousness enables. HOT theory's core mechanism is the Transitivity Principle: a state becomes conscious when targeted by a non-conscious higher-order thought. This is a constitutive claim about what makes a state conscious, not a functional claim about what consciousness then does. The associated functions Rosenthal and Lau cite (monitoring, confidence judgments, error-correction, reality monitoring, flexible planning) are attributed to the higher-order/metacognitive SYSTEM, and crucially the theory concedes that intentional and rational processing — including such metacognitive computation — can occur unconsciously. Because the HOT itself is typically unconscious and rational processing runs without consciousness, the theory explicitly holds that the unique function attributable to consciousness per se is "modest and contested," and the framework even courts near-epiphenomenalism. It therefore identifies functions of higher-order representation, not functions enabled by consciousness, and fails the specific positive-account bar.

Key evidence: Lau & Rosenthal (2011) marshal metacognition/confidence/signal-detection data to a higher-order SYSTEM, but the theory itself separates this from a strong functional claim, conceding intentional/rational processing occurs unconsciously and that consciousness's unique function is "modest and contested" (with the noted near-epiphenomenalism limitation).

Irruption Theory does name specific adaptive functions — behavior switching, adaptive learning via the self-optimization model, embodied skill development, creativity, and flexible/anticipatory response. However, the theory explicitly attributes these to irruptions (transient increases in material underdetermination of bodily activity / motivated agency), not to phenomenal consciousness as such. The theory's own commitment, as stated, is that "phenomenal consciousness as such is not assigned a sharply distinct function list separate from motivated agency; function is framed at the level of motivated, autonomous activity." Since the question asks specifically which functions are enabled by CONSCIOUSNESS, and the consciousness-generating process in the theory is "absorption" (matter compressing high-dimensional activity into low-dimensional experience) rather than irruption, the named functions are not actually predicated of consciousness — they are predicated of motivated underdetermination events. Under the strict standard, attributing a function list to motivated agency while declining to assign one to consciousness itself does not answer the question as written.

Key evidence: The theory's explicit statement (Froese 2023/2024) that "phenomenal consciousness as such is not assigned a sharply distinct function list separate from motivated agency; function is framed at the level of motivated, autonomous activity" — the functional account targets irruption/motivated agency, not consciousness per se, while consciousness corresponds to the separate "absorption" process.

PP/FEP offers an unusually rich and specific functional taxonomy — perception as hierarchical Bayesian inference, action as active inference, attention as precision-optimization, learning as model-updating, emotion/selfhood as interoceptive inference, and planning/imagination as temporally-thick counterfactual inference. But the Function question asks which functions are enabled by CONSCIOUSNESS specifically, and PP attributes these functions to the predictive machinery as such, not to its being conscious. By the theory's own admission (a stated limitation), many unconscious processes are equally predictive/Bayesian, and PP lacks any principled criterion separating conscious from unconscious inference. It therefore cannot say which of its enumerated functions require or are enabled by consciousness rather than by unconscious prediction — so it names functions of the brain, not functions of consciousness.

Key evidence: Hohwy & Seth 2020 and Seth & Bayne 2022 note PP is primarily a theory of perception/action/brain function with no principled criterion distinguishing conscious from unconscious predictive inference, leaving the functional role specific to consciousness unspecified.
