Consciousness as a Decoherent Process: An Explanatory Model Connecting Quantum Physics and Cognitive Science

A proposed Consciousness Decoherence Model uses quantum decoherence theory as a structured metaphor to explain how conscious awareness arises. Pre-conscious states are described as a superposition of multiple possible contents, and conscious awareness forms when decoherence—triggered by sensory input, interoception, and attention—stabilizes one specific state into reportable awareness. The model unifies diverse cognitive phenomena such as creative insight, decision paralysis, and psychopathological states under a single dynamical logic, and is compared with Global Neuronal Workspace Theory and Integrated Information Theory.

Abstract

This paper proposes a "Consciousness Decoherence Model" grounded in a structured metaphor drawn from quantum decoherence theory. The model frames pre-conscious states as a superposition of multiple possible contents, and characterizes the formation of conscious awareness as a process of decoherence—triggered by internal and external "environments" (including sensory input, interoception, and attention)—that stabilizes one specific classical state into reportable awareness. Through systematic conceptual mapping and comparative analysis with Global Neuronal Workspace Theory, Integrated Information Theory, and other recent decoherence-inspired frameworks, the model unifies diverse cognitive phenomena such as creative insight, decision paralysis, and psychopathological states under a single dynamical logic.
