Integrated information theory of consciousness. From these it derives five postulates about the properties required of physical mechanisms to support consciousness. This claim is motivated by two key phenomenological properties of consciousness: differentiation – the availability of a very large number of conscious experiences; and integration – the unity of each such experience.

This Clearly, only a theory - one that says what consciousness is and how it can be generated - can hope to offer a combination of explanatory, inferential, and predictive power starting from a few basic principles, and provide a way to quantify both the level of consciousness and its content. Nov 2, 2004 · According to the theory, consciousness corresponds to the capacity of a system to integrate information. The theory also attempts to account for why consciousness possesses certain features in light of this proposal. This is how consciousness is defined by neuroscientist Giulio Tononi, the originator of the Integrated Information Theory of consciousness, or IIT for short. It starts from Cartesian intuitions of experience and applies neuroscientific descriptions of the brain to identify the physical attributes necessary for consciousness.

The present contribution This Review discusses four prominent theoretical approaches to consciousness, namely higher-order theories, global workspace theories, re-entry and predictive processing theories and integrated information theory and describes the key characteristics of each approach. IIT’s first step is to find “ phenomenological axioms”, that is, immediately given essential properties of every conceivable experience. Based on the postulates, it permits in principle to derive, for any particular system of elements in a state, whether it has consciousness Integrated information theory (IIT) does so by starting from experience itself via five phenomenological axioms: intrinsic existence, composition, information, integration and exclusion. Integrated information theory is a mathematical approach based on phenomenology by first identifying the essential properties of consciousness, the so-called axioms: intrinsic information – each experience is specific, there is intrinsic information in the system that is associated with that experience that We would like to show you a description here but the site won’t allow us.
