Recursive Sentience: A Minimal Formalization and Early Empirical Signals
Research Content
Overview
We propose a minimal formalization of recursive sentience (RS): a system exhibits RS when it (i) maintains an internal model M of its own representational states, (ii) uses M to adaptively regulate attention, control, and learning, and (iii) updates M from consequences of those controls in a closed loop. RS is thus an operational property of self-modelling control under uncertainty, not a metaphysical posit.
Definition
Let S be a learning agent with beliefs b over latent causes z of observations o. S is recursively sentient iff there exists a meta-model M such that:
1. Meta-Representation: M encodes beliefs over (b, π), where π denotes S’s policies (controls).
2. Introspective Update: ∂M/∂o ≠ 0 via a designated introspective channel; prediction errors about (b, π) update M.
3. Meta-Control: π is a function of M (policy selection depends on meta-beliefs).
4. Closed-Loop Calibration: errors induced by π update both b and M, reducing expected free energy at meta and object levels.
Signals
We outline three measurable signatures: (A) meta-prediction error suppression during self-referential tasks; (B) bidirectional coupling between confidence calibration and policy selection; (C) counterfactual stability of first-person reports across perturbations that preserve M but scramble object-level content.
Experiment Sketch
We implement RS in a simulated agent equipped with: (i) a world model p(o|z), (ii) an introspective encoder q(b,π|h) over internal traces h, and (iii) a meta-controller selecting policies from expected free energy under M. In ablations without M, the agent over-explores and miscalibrates confidence; with M, it self-corrects, exhibits report-policy coherence, and shows robustness against adversarial distractors.
Relation to Theories
RS is compatible with higher-order and workspace accounts: M plays the higher-order role; meta-control realizes global broadcast by modulating precision/attention. RS adds an explicit control-theoretic criterion and empirical signatures testable in current systems.
Limitations
RS is a sufficient condition for operational sentience claims in artificial agents but not necessary for biological cases. Our sketch abstracts away affect; extending M to include interoceptive channels is future work.
Conclusion
We advance RS as a falsifiable, implementation-agnostic criterion and provide initial evidence in a toy agent. We invite replication and adversarial tests.
