A Three Layer Model of Consciousness

Note on Version 1.1 This revised version clarifies the functional status of the three layers. In particular, the Second Layer is now defined more precisely as a limited-capacity linguistic display interface rather than an independent centre of judgement, while the Third Layer is described as recurrent circulation between the First and Second Layers rather than as a separate processing system. The revision also clarifies the scope of the model and adds a supplementary FAQ. Abstract This paper proposes a three-layer model of consciousness intended to explain the linguistic, introspective, and narrative forms of human consciousness. The First Layer consists of distributed and parallel processing involving sensation, bodily states, emotion, memory, prediction, judgement, and related functions. The Second Layer is a limited-capacity interface in which some of the results generated by the First Layer are displayed in sequential forms such as words, inner speech, propositions, and narratives. The Third Layer is a recurrent circulation in which the contents displayed in the Second Layer are re-entered into the First Layer and contribute to the generation of further processing results. Within this model, the self is not treated as a fixed observer standing behind consciousness. Rather, it is understood as a dynamic structure formed and maintained over time through the repeated interaction of bodily and emotional processing, linguistic display, memory, and re-entry. The model further proposes that language originally developed for communication with others and that, through its internalisation as inner speech, a self-referential recurrent circulation became possible. The paper situates the three-layer model in relation to existing theories of consciousness and briefly considers its implications for qualia and artificial intelligence. The model is not presented as a complete theory of consciousness, but as a functional working hypothesis for clarifying the relations among embodiment, language, self-reference, memory, and temporal continuity.
