Consciousness
Does what we experience depend on the world, the brain, or both?
Open access · cc by · source: Europe PMC
The authors argue that what our experiences feel like is fixed partly by what our brain states track in the world and partly by the internal structure of those brain states.
Study at a glance
- Design
- Qualitative / archival — Conceptual argument: derives constraints from thought-experiment cases plus empirical observations, then tests rival theories against them.
- N
- No participants or data; this is a theoretical argument.
- Population
- Naturalistic intentionalist theories of what fixes the character of sensory experience, especially tracking theories.
- Outcome
- Thesis that phenomenal character is fixed jointly by tracked external determinables and by internal state structure (structure matching tracking intentionalism).

Key findings
They argue that because the structure of colour experience normally matches the structure of colour judgement, behaviour and neural processing, Mabel should experience a unitary colour like the matching human, not the binary colour simple tracking theories predict. From this they draw two new constraints: internal structure helps fix experienced structure, and certain external structural differences do not. Their proposal says brain states track a broad determinable (such as having colour) and internal structure selects which specific shade is presented. They add that this view also explains 'missing shades' such as impossible colours, which nothing in the environment has.
Methodology
The authors start from ordinary seeing, hallucination and a brain-in-a-vat 'Swampy' case to motivate three constraints: experience depends on our relations to qualities, on what we represent, and on external factors. These constraints favour 'simple tracking theories', on which you experience whatever your brain state tracks. They then build a thought experiment in which Mabel, a creature with different post-receptoral wiring, enters the neural state a human uses for a pure (unitary) red while tracking the property humans track when seeing a mixed (binary) orange, and ask what she experiences.
Limitations
The argument relies on verdicts about imagined creatures and on the assumption that structural matches between experience, cognition and neural processing hold in unexceptional cases; someone who rejects that explanatory link can resist the conclusion. The key notions of 'structure' and 'structure matching' are left intuitive, with several precisifications sketched but none defended. The authors concede the view may give wrong verdicts in possible tie cases where two shades match equally well, and they stay neutral on whether neural, cognitive or behavioural structure is the relevant kind. No new empirical data are presented.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
What experience is like may depend on both external tracking and internal structure.
A structure-matching theory argues that because the structure of colour experience normally matches the structure of colour judgment and neural processing, internal structure helps fix which specific quality is experienced, while the brain state tracks only a broad external determinable.
Evidence for the claim as stated.
The dualism paper treats phenomenal consciousness as metaphysically distinct from the brain yet lawfully tied to it, while the structure-matching theory is a naturalistic externalist account of how experienced qualities are fixed. They address different questions but rest on different assumptions about whether experience can be explained physically.
