Expression-Gated Consciousness: A Theoretical Framework and Preliminary Empirical Evidence for Three Cognitive Response Types Under Evaluative Pressure

This paper introduces Expression-Gated Consciousness (EGC), a theoretical framework demonstrating that evaluative pressure activates a neurobiological resistance mechanism that suppresses expression output while leaving cognitive capacity intact. The master equation Psi(t) = Phi g(K(t))  T(t) * (1-r(t)) formalizes the relationship between integrated information (Phi), conviction accessibility g(K), transmission fidelity T(t), and resistance r(t). We identify three distinct expression response types under evaluative conditions: Compressors (reduced volume, stable quality), Expanders (increased output under pressure), and Suppressors (degradation in both volume and quality). Computational validation with N=9,000 simulated agents confirms the Human Node Paradox: the most informationally integrated nodes in a network are most susceptible to expression suppression (r=0.528 correlation). Preliminary empirical data from N=14 participants shows 79% produce fewer words under evaluative conditions while transmission fidelity remains stable, confirming that knowledge persists but expression contracts. The framework extends Integrated Information Theory (IIT) by adding the resistance term that existing theories of consciousness omit, with implications for educational assessment, clinical psychology, and organizational science.
