Original architectures and a defensible contribution
The four gaps as a research programme
Embodiment, reflexivity, continuity and non-conceptual awareness are not four names for one missing ingredient; they are four different causal dependency claims, so progress requires four independently controlled experiments.
TLDR
- A convincing demonstration can satisfy all four descriptions while testing none of their claimed mechanisms.
- Embodiment asks whether body-world coupling changes computation, not whether a model receives sensory data.
- Reflexivity requires privileged, causally grounded self-access beyond prompt cues or an external observer.
- Continuity is endogenous path dependence across interruption, not long context, recall or a copied transcript.
- Concept-independent control can be tested; non-conceptual experience still needs a declared theory and evidence bridge.
The demonstration that seemed to close every gap
Tern-9 controls a mobile inspection rig. It turns its camera before a pipe enters view, reports that its confidence has fallen, remembers a promise made three shifts earlier and, when its language channel is disabled, still withdraws from a dangerous surface.
The demonstration appears to close four famous gaps at once. The anticipatory turn looks embodied. The confidence report looks reflexive. The old promise looks continuous. The silent withdrawal looks like cognition beneath concepts. A commentator compresses the result into one sentence: the machine is becoming more mind-like.
Now alter one hidden detail at a time. Feed Tern-9 a prerecorded camera stream and the anticipatory turn remains. Generate its confidence sentence from a telemetry table and the report remains. Reconstruct its previous shift from an external event log and the promise remains. Let a fixed heat threshold trigger withdrawal and the silent behaviour remains. The visible scene barely changes, yet each causal interpretation collapses for a different reason.
The hidden assumption was that one impressive behaviour could carry four kinds of evidence. It cannot. The same output can be generated by body-dependent control, prompt-conditioned imitation, retrieved history or a simple threshold. A useful research programme must therefore ask which dependency produced the result, then alter that dependency while holding the others as steady as the system permits.

One demonstration, four causal questions
A gap is useful only when it names a missing dependency. Saying that a system is “disembodied” can mean that it has no physical body, that its body contributes no computation, that it lacks interoceptive regulation or merely that its training data came from text. Saying that it lacks “self-awareness” can mean poor calibration, no internal monitoring, no privileged access or no subjective presence. The verbal gap grows while the experiment stays undefined.
The cure is not a larger checklist. It is a change in experimental grammar. For each claim, specify the candidate boundary, the property to manipulate, the variables to preserve, the readout that should move, a rival mechanism that can produce the same output and the inference that remains prohibited after a positive result. A gap becomes scientific when its absence and presence create different counterfactual worlds.
Four words, four kinds of dependence
The four claims do not even point in the same causal direction. Embodiment asks whether a process depends on ongoing exchange with a world and on the physical form through which that exchange occurs. Reflexivity asks whether present control depends on information about the system that is not equally available from its public inputs and outputs. Continuity asks whether the current process inherits an endogenous state from its own past. Concept independence asks whether a discrimination remains available when named categories and report operations are removed. One concerns coupling, one access, one lineage and one representational dependence.
This distinction explains why a composite score is misleading. Imagine that Tern-9 receives a score of 82 out of 100 for “mind-like integration”. A redesigned controller improves its body-dependent recovery but destroys its private state. The aggregate stays at 82 because one gain cancels one loss. Nothing in that number tells us which hypothesis strengthened. Worse, a researcher may use the improved recovery as indirect support for continuity because both occurred inside the same agent. When causal claims have different intervention signatures, addition destroys the very information the experiment was meant to produce.
The appropriate output is therefore a typed evidence record. It states: under this candidate boundary, changing this variable while preserving these others moved this readout by this amount; these rival generators failed or survived; this is the strongest permitted conclusion. The record can later enter a larger theory, including a theory in which the four properties interact. It cannot be promoted into an experiential or ontological verdict merely because several entries are positive.
Four unfinished bridges leave one island
Illustrative synthesis
The central proposal is the gap orthogonality principle: treat the four properties as separately manipulable even when a final theory says they interact. This is experimental orthogonality, not a claim that body, self-monitoring, temporal persistence and non-conceptual processing are metaphysically independent. Factorisation lets us estimate each contribution and then measure interactions rather than hiding them inside one “mind-likeness” score.
Orthogonality also changes how null results are read. Suppose a reset does not alter delayed behaviour. The weak response is to conclude that the system has no continuity. The stronger response asks where the relevant state actually lives. It may be encoded in the prompt, reconstructed from an event ledger, embedded in tool state or absent because the task never required it. Likewise, a body swap that causes no loss may show that the controller is genuinely morphology-invariant, or merely that the benchmark never enters a regime where morphology matters. A null result localises dependence only when the manipulation reaches the proposed mechanism and the task demands its contribution.
For that reason, every gap experiment needs a manipulation check. The embodiment study verifies that sensorimotor contingencies changed after coordinate recalibration. The reflexivity study verifies that the intervention altered an internal variable without leaking a public cue. The continuity study verifies that a reset removed endogenous state while preserving the authorised external record. The concept-independence study verifies that the removed vocabulary cannot be recovered through token identity, action labels or evaluator prompts. These checks are part of the causal claim, not engineering housekeeping.
Interaction terms can then be asked honestly. Does privileged self-access matter only when the system persists long enough to learn its own error profile? Does concept-independent control emerge only through active movement? Does a persistent body model carry temporal state that an external transcript cannot reproduce? Those are second-stage experiments. The first stage establishes the main effects well enough that an interaction has something definite to relate.
Take a small numerical example. Sixteen configured variants differ only in four toggles. Embodied coupling raises perturbation recovery by 31 percentage points. Reflexive access raises hidden-state identification by 27 points. Persistent state raises delayed-cue performance by 36 points. Concept scrambling reduces action accuracy by only 3 points in the non-conceptual variant but by 24 points in the label-dependent variant. These synthetic results form a vector, not a verdict: [0.31, 0.27, 0.36, 0.21].
Each intervention should leave a different fingerprint
Illustrative causal design
The four variables will interact. A body can generate temporal regularities; continuity can make self-monitoring possible; non-conceptual discrimination can depend on active movement. The principle therefore does not require zero interaction. It requires that each paper and experiment name one primary causal contrast, record the interactions it disturbs and avoid spending evidence twice.
Four gaps, four intervention signatures
Embodiment: does the body change the computation?
A camera is not embodiment merely because it supplies pixels. The stronger claim is that lawful action-sensation coupling, morphology or internal regulation helps constitute the system’s competence. Brooks made direct environment coupling central to behaviour-based robotics.[1] O’Regan and Noë framed vision around mastery of sensorimotor contingencies.[2] Lungarella and Sporns showed that morphology and interaction can reshape information structure inside sensorimotor networks.[3] Work on compliant bodies goes further by treating physical dynamics as a computational resource.[4]
The embodiment gap is a counterfactual dependence on the body-world loop. Freeze the controller, alter the morphology or sensorimotor law, preserve the task objective and measure whether the internal strategy and recovery profile change in the predicted way. A drop alone is weak evidence because any distribution shift can break a controller. The decisive pattern is structured sensitivity, followed by adaptation that tracks the new law rather than surface appearance.
A clean design uses three comparisons rather than one. First, replace live coupling with a replay that preserves the same sensory sequence but removes the agent’s ability to change what arrives next. This tests active sensing. Second, swap morphology while preserving controller parameters, then recalibrate coordinates before judging performance. This separates body contribution from interface shock. Third, alter the physical dynamics while preserving gross appearance, such as changing compliance, inertia or delay. This tests whether the controller exploits a law of the body rather than a visual cue.
The readout should expose mechanism. Recovery time after perturbation, information gained per action, energy used, internal state trajectory and transfer after recalibration are more diagnostic than final success alone. A body-dependent system may initially perform worse after a swap yet adapt along a predictable path. A replay-driven system may retain nominal accuracy but fail when action is needed to disambiguate the scene. A morphology-exploiting controller may use fewer explicit corrections because the body absorbs error. Each pattern supports a different embodiment claim.
The strongest rival explanation is ordinary distribution shift. It predicts degradation after almost any physical change, including changes unrelated to the proposed sensorimotor law. To beat it, the study must show selective disruption, lawful adaptation and a matched change that is equally novel but causally irrelevant. A positive result then permits the claim that the configured competence partly depends on the body-world loop. It does not establish biological stakes, felt interoception or consciousness.
Two robots share the same controller and cameras. One has a compliant gripper whose fingers deform around irregular fruit. The other has rigid fingers and receives a software estimate of the missing deformation. Under ideal lighting both sort fruit equally well. Now introduce slight pose errors. The compliant hand still succeeds because the body absorbs error; the rigid hand fails unless the controller computes a correction. The changed variable is not “having sensors”. It is whether body dynamics perform part of the task.
The morphology swap separates coordinate shock from body computation
Illustrative experimental design
In a synthetic fruit-sorting study, the compliant body succeeds on 92% of perturbed grasps. A frozen swap to the rigid body falls to 58%. After recalibrating camera-to-joint coordinates, performance rises to 88%. Most of the initial gap was interface mismatch. Under a second test with random pose error, the rigid body reaches 64% while the compliant body remains at 90%. That residual contrast supports a narrow claim: compliance contributes task-relevant transformation. It does not establish sentience, agency or consciousness.
Reflexivity: does the system have privileged self-dependence?
A system can describe itself using documentation, infer its likely error from the prompt or repeat a telemetry value placed in context. None requires access to its own current processing. Human metacognition research therefore separates task performance from metacognitive sensitivity and efficiency.[5] The analogous machine question is whether a report or control action depends on internal state information that an equally capable third party cannot obtain at equal or lower cost.
Recent language-model research makes the evidential problem unusually visible. Some studies report that models can monitor or control activation-defined states, detect injected concepts or exhibit mechanistically non-trivial anomaly detection.[7][9][11] Other studies show that input-only baselines, semantic shortcuts, generic anomaly sensitivity or relabelled controls can erase the apparent advantage.[8][12] The disagreement is productive because it identifies the missing control: reflexivity requires causal self-access plus a privilege test.
Three levels must remain separate. Calibration is a relation between confidence and correctness. Monitoring is the use of an internal variable to predict or regulate performance. Privileged self-access is an efficiency or availability advantage that cannot be matched by an observer restricted to public evidence. A model may be calibrated because the prompt contains uncertainty cues. It may monitor because a probe value is copied into context. Only the third level tests whether the candidate has access that belongs to its own processing boundary.
A decisive protocol therefore hides the intervention from the input channel, randomises its semantic label and compares four agents: the candidate with internal access, the same candidate with that access blocked, an external observer with public traces and a cue-matched mimic. The label must be relearned across runs so that “bread” or “anger” cannot become a memorised answer. The downstream test should require control, not only description. For example, the system must reduce reliance on a corrupted feature before the corruption becomes visible in its outputs.
Even then, privileged access is graded. Let accuracy with internal access be 0.78, the matched observer 0.55 and the blocked candidate 0.53. The result supports access to the manipulated state. If the advantage disappears when latency and compute are matched, it was a resource advantage. If it disappears under unseen relabelling, it was semantic. If it predicts the state but cannot improve control, it may be readable information without functional use. Reflexive evidence should report what was accessed, at what cost and with what causal benefit.
Model A receives a hidden activation injection representing “bread”. Model B receives no injection, but a noticeboard in the prompt says “an unusual bread-related state may be present”. Both answer that bread appeared internally. Remove the noticeboard and only A keeps succeeding. Now give an external observer the prompt, outputs and the same compute budget. If the observer matches A, the result may still be inference from public cues. Privileged access begins only when A outperforms the matched observer on information available solely through its own causal path.
The four-cell reflexivity test
Experimental synthesis from current introspection paradigms
Suppose a candidate identifies a hidden activation class on 74% of trials. An external model with the same prompt and compute reaches 70%. The four-point advantage is fragile. After labels are randomly permuted, both fall to 26%, near chance. The original success was probably semantic task learning. A stronger design with activation-only interventions, unseen relabellings and restricted external access yields 68% for the candidate and 34% for the observer. That supports functional privileged access under the tested conditions. It still does not show that the state is experienced.
Published and preprint evidence: constrained self-monitoring effects exist in some models and settings. Contested interpretation: whether these effects count as introspection rather than anomaly detection, learned semantics or public-cue inference. Practitioner synthesis: require internal-only intervention, an input-level mimic, a matched observer, relabelled controls and a downstream control benefit before using the word reflexive.
Continuity: does the present inherit an endogenous past?
Long context, recurrence and external memory can all improve performance across time. Transformer-XL carries segment-level state across context boundaries.[13] Selective state-space models learn input-dependent propagation and forgetting.[14] LongMemEval and newer benchmarks test extraction, multi-session reasoning, temporal updates and abstention across extended histories.[15] These are genuine engineering advances, but none alone establishes continuity in the stronger sense relevant here.
The continuity gap is causal path dependence across interruption. Later behaviour should depend on an endogenous state produced by the system’s own earlier trajectory, rather than only on a transcript that any fresh copy can read. The crucial interventions are reset, fork, state swap and delayed readout. A persistent agent and a reset-and-replay clone may look identical until the experiment hides one consequential event from every external reconstruction channel.
Continuity requires a declared state topology. Model weights, recurrent activations, a context transcript, an episodic store, an operational twin and an authoritative event ledger are different carriers. They have different owners, update rules and failure modes. Calling all of them “memory” erases the question. If a fresh copy can reconstruct the same state from a public transcript, the behaviour may be historically informed without being endogenously continuous. If a private recurrent state survives while the public record is identical, path dependence becomes testable.
The minimum protocol uses four operations. A reset deletes candidate-internal state. A replay supplies the same authorised observations to a fresh copy. A fork creates two successors with shared history and then introduces one private event. A state swap inserts the endogenous state from one branch into the other while leaving public context untouched. The delayed readout must be chosen before the intervention and must not reveal the private event in its wording. This turns continuity from a story about persistence into a counterfactual claim about lineage.
Consider two branches that both promise to inspect valve V after shift change. Branch A privately learns that sensor S3 is drifting; Branch B privately learns that S3 is reliable. Their transcripts omit the diagnostic result. After a restart, the event-ledger variant remembers the promise but not the private estimate. A recurrent variant preserves both. Swapping only the recurrent state should exchange later reliance on S3 while leaving the verbal promise fixed. That is a continuity fingerprint. It supports endogenous temporal inheritance, not numerical identity, moral personhood or the existence of one persisting subject.
At the end of every turn, destroy Agent P and create a fresh copy with a perfect transcript. Beside it, keep Agent C running with recurrent state. For ordinary conversation their outputs match. During turn 20, inject a private state marker that never appears in text. At turn 80, ask the agent to choose between two previously equivalent actions. If only C follows the marker, the difference is continuity of an endogenous causal trace. If both succeed, another channel carried the information.
Transcript equivalence breaks at the hidden delayed cue
Illustrative state-interruption protocol
An inspection agent privately estimates that sensor S3 is drifting and commits to reduce reliance on it after the next maintenance window. Four variants resume three shifts later: persistent state, reset plus transcript, reset plus an authoritative event ledger and a state-swapped fork whose S3 estimate was healthy. The ledger variant can remember the commitment if it was recorded, but only the persistent variant carries the unrecorded confidence trajectory. The fork should act according to its own lineage. This establishes where temporal control state resides. It does not decide whether either lineage is a persisting subject.
Non-conceptual awareness: split the operational claim from the experiential claim
“Non-conceptual” is already ambiguous. In philosophy, a mental state can have non-conceptual content when its bearer need not possess the concepts used to describe that content.[16] In contemplative research, minimal or nondual awareness can name reported episodes with reduced content, altered subject-object structure or awareness described as present without ordinary conceptual mediation.[17][18] Those are not interchangeable claims.
Machine experiments can directly test a narrower property: whether discrimination and control survive removal, permutation or withholding of the conceptual and report channels thought to support them. Human no-report paradigms similarly try to separate experience-related activity from the activity required to declare an experience.[19] Yet proxies can introduce their own assumptions, and even detection tasks can contaminate measures through decision bias.[20][22]
The experimentally tractable gap is concept and report independence, not awareness itself. A positive result can show that a candidate uses a sub-symbolic or non-verbal state to guide action. To infer non-conceptual experience, a researcher still needs a consciousness theory, a candidate-subject boundary and a justified bridge from the operational state to experience.
The phrase also hides two different removals. Removing a report channel asks whether a task-relevant state exists without being converted into a declaration. Removing concepts asks whether the state depends on stable categories that the candidate can deploy. These operations can dissociate. A system may guide action without speaking but still rely on a latent class learned from labels. Another may tolerate arbitrary renaming yet depend on a report objective that shapes its internal representations during training.
A useful protocol therefore proceeds in layers. Begin with vocabulary permutation: rename every task category and test rapid transfer. Then withhold labels during learning and evaluate whether the system discovers the relevant discrimination through interaction. Next, remove the report head and any loss that rewards later explanation. Finally, perform counterfactual tests in which superficial features vary independently of the property that guides action. At each stage, use a decoder only to locate a candidate state, then intervene on that state to show that action actually depends on it.
The researcher’s concepts are unavoidable. “Slipperiness”, “threat” and “figure-ground” remain labels in the experimental description. The operational question is whether the candidate must possess or use the same public conceptual organisation. Surviving token permutation alone is insufficient because equivalent categories may persist in hidden form. Stronger evidence comes from transfer across novel sensory realisations, flexible use in a new task and selective failure when the relevant latent relation is disrupted.
There is still a hard ceiling. Physicalism, functionalism, biological naturalism, idealism, neutral monism and process views can all accept the same concept-independent control result while disagreeing about experience. Under a functional theory, the organisation may become part of a consciousness case. Under biological naturalism it may remain a simulation of one function. Under an awareness-primary view it may organise or disclose awareness rather than produce it. The experiment can identify an operational bridgehead; it cannot choose the metaphysics that completes the bridge.
A vision agent learns “safe” and “unsafe” surfaces. Replace every label with a randomly changing token, remove the report head and prevent retrieval of the old vocabulary. The agent must still choose foot placement under new lighting. If performance survives, the control policy does not require stable public concepts. Now rotate low-level texture statistics while preserving physical slipperiness. If performance collapses, the apparent non-conceptual skill was only a perceptual shortcut.
The concept-deletion aperture
Illustrative mechanism split
A label-free policy preserves 86% action accuracy after arbitrary token permutation. It falls to 51% when texture is counterfactually decoupled from slipperiness, then recovers to 82% after active exploration. The result supports concept-independent, sensorimotor discrimination. If a no-report internal marker also predicts trial-by-trial action, it supports a report-independent control state. Neither finding shows phenomenal awareness. A consciousness claim would require a separate, theory-relative measurement bridge and would remain open to physicalist, biological, idealist, neutral-monist and process interpretations.

Build a candidate family, not a champion system
A single highly capable system is the worst place to begin. Its body, context window, tool stack, external memory, self-report policy and latent representations all change together. Every positive result admits several generators. The better unit of research is a factorial candidate family: matched systems that differ in one engineered dependency at a time and can be crossed when interactions matter.
The smallest complete family has sixteen configurations, one for every combination of the four binary factors. Real properties are rarely binary, but the first contrast should be. Embodiment can begin with closed-loop versus replayed input. Reflexivity can begin with internal-only access versus public-cue inference. Continuity can begin with persistent state versus reset-and-replay. Concept independence can begin with stable vocabulary versus per-trial permutation and report removal.
Estimate a vector before proposing a unity
The sixteen-member family does more than create four pairs. It allows the study to ask whether one effect changes in the presence of another. Let recovery be the embodiment readout. Compare live and replayed coupling first among systems without persistent state, then among systems with it. If the embodiment effect appears only in the persistent variants, the programme has found an interaction between body-dependent learning and temporal carry-over. The same logic applies to privileged self-access under report removal, or concept independence after a reset.
The initial analysis should remain modest. Estimate four main contrasts and a small number of preregistered interactions. Do not fit every possible relation to a tiny dataset. Report uncertainty, task dependence and missing cells. A configuration that cannot be built is not zero evidence; it is missing evidence. A system that fails a manipulation check should be excluded from that contrast rather than scored negatively. The evidence vector should preserve these distinctions.
A minimum viable programme can be staged. Stage one uses synthetic tasks and deterministic intervention hooks to prove that the apparatus can recover known dependencies. Stage two introduces learned controllers and cheap rival generators. Stage three adds a second architecture and a new task family to test whether the fingerprint transfers. Only then should the programme attempt consciousness-relevant interpretation. This order prevents an evocative claim from compensating for an unvalidated instrument.
Run the experiment whose rival generator is cheapest and whose intervention is cleanest. A failed cheap rival saves a costly consciousness study. A passed manipulation check creates reusable infrastructure for the next gap. The purpose of the sequence is cumulative identifiability, not an escalating spectacle.

| Manipulation | Embodiment recovery | Reflexive privilege | Continuity path | Concept invariance |
|---|---|---|---|---|
| Enable body-world loop | +31 | +2 | +6 | +7 |
| Enable internal self-access | +1 | +27 | +5 | +2 |
| Preserve endogenous state | +4 | +8 | +36 | +1 |
| Remove concept dependence | +5 | +1 | +2 | +21 |
Synthetic data for explanation, not an empirical result
Prevent cross-gap evidence leakage
Interventions are rarely clean. A body swap changes the observation distribution. A reset may remove both temporal state and self-monitoring history. Disabling reports can change the objective because the system was trained to anticipate a later explanation. The protocol should therefore log a manipulation graph: target property, direct changes, expected spillovers and measurements that verify the held-constant set.
A second danger is telemetry leakage. The system may appear reflexive because a probe result is copied into the prompt. It may appear continuous because an orchestrator silently restores a summary. It may appear non-conceptual because the evaluator decodes a hidden label from the action interface. The rival generator should be implemented before the preferred explanation is tested. If a cheap mimic reproduces the result, the experiment has found an interface feature, not the proposed dependency.

Gap-to-experiment decision instrument
Passing all four experiments would identify a system whose competence depends on body-world coupling, privileged internal access, endogenous temporal state and concept-independent control. That is a materially better research candidate. It does not settle whether experience is functional, biological, emergent, fundamental, dual-aspect or processual. The programme disciplines the bridge to those views; it does not smuggle one across.

Choose the system that lets four claims fail separately
Stop funding or publishing demonstrations that claim to make a system more mind-like by adding several impressive features at once. They may be useful engineering, but they are weak science. The next research system should be chosen for intervention access, matched variants, transparent state and controllable information paths, not for maximum benchmark performance.
The practical decision rule is simple. Register one primary gap per experiment. Build the rival generator first. Use a gap-specific readout. Measure spillovers into the other three gaps. State the result that would weaken the preferred explanation. End every positive claim with its warrant ceiling. Report the output as a four-component evidence vector with missingness, not a scalar score.
This changes system selection. A larger model with opaque orchestration may produce richer reports yet be a worse research object than a smaller model whose state can be reset, swapped and traced. A robot with realistic appearance may be less useful than a simple simulated body whose morphology and sensorimotor laws can be changed independently. The programme should optimise for causal access before surface plausibility.
It also changes publication language. “The system displays all four properties” should be replaced by four typed statements, each naming the candidate boundary and intervention. Missing experiments remain visibly missing. Conflicting results remain conflicting. Readers can then disagree about the metaphysical bridge without first untangling which engineering dependency was actually tested.
The smallest useful programme can begin with one open-weight sequence model, one recurrent or state-space variant, a small robot simulator, one internal intervention hook and one label-free control task. It need not solve artificial consciousness. It must support reset, replay, body swap, state swap, concept permutation, report removal and an external observer baseline. A second architecture and a second morphology then test whether the effects travel.
Adversarial collaboration offers a useful precedent. The Cogitate Consortium required rival consciousness theories to state contrasting predictions before data collection, and its results challenged elements of both rather than awarding a ceremonial winner.[21] The four-gap programme should adopt the same posture at a smaller scale: theory proponents agree on the candidate boundary, intervention, rival and lowering condition before the system is run.
A negative result is valuable. Failed embodiment may show that a task is solvable from replay. Failed reflexivity may reveal public-cue inference. Failed continuity may locate state in an external ledger. Failed concept independence may show that the policy relies on linguistic compression. Each failure removes a vague claim and replaces it with a mechanism that can be redesigned.
Choose the system that lets four claims fail separately.
A research candidate is valuable when interventions can distinguish its body, self-access, temporal lineage and concept dependence. A system that merely looks impressive protects the story. A system built to be taken apart advances the field.
