The Projective Consciousness Model: Projective Geometry at the Core of Consciousness and the Integration of Perception, Imagination, Motivation, Emotion, Social Cognition and Action.

Brain Sci October 9, 2023 David Rudrauf, Grégoire Sergeant-Perthuis, Yvain Tisserand et al.

The Projective Consciousness Model proposes that projective geometry forms the core structure of conscious experience, integrating perception, imagination, motivation, emotion, social cognition, and action. The model argues that consciousness is not merely a byproduct of neural activity but is fundamentally organized by projective geometric principles, which allow the mind to construct a unified, egocentric spatial framework. This framework underpins how we perceive the world, imagine scenarios, feel emotions, and act. The theory suggests that these geometric structures enable the seamless integration of diverse mental functions, offering a unified account of consciousness that bridges phenomenology and neuroscience.

Influence of the Geometry of the world model on Curiosity Based Exploration

arXiv Preprint Archive April 1, 2023 Grégoire Sergeant-Perthuis, Nils Ruet, David Rudrauf et al.

The geometry structuring an agent's internal world model shapes its spatial awareness and action planning. Using active inference, the authors show that a projective group structure transforms epistemic value nonlinearly, generating approach behaviors toward an object of interest, whereas the Euclidean group has no effect on epistemic value, leaving the agent idle. Formal simulations of a simple search task demonstrate these distinct behaviors. The projective group structure is linked to the Projective Consciousness Model, which is known to capture key features of consciousness. The work argues that geometry plays a key role in information integration and action planning by structuring a priori an agent's internal representation.
