In short, according to IIT, consciousness requires a grouping of elements within a system that have physical cause-effect power upon one another. This in turn implies that only reentrant architecture consisting of feedback loops, whether neural or computational, will realize consciousness.
What is the basis of the integrated information theory?
Integrated information theory (IIT) attempts to identify the essential properties of consciousness (axioms) and, from there, infers the properties of physical systems that can account for it (postulates).
Can information theories explain consciousness?
In short, you cannot explain consciousness by referring to observer-relative information, because the information in question requires consciousness. Information is only information relative to some consciousness that assigns the informational status.
What does information mean in integrated information theory?
According to the theory, consciousness (or conscious experience) is characterized in terms of integrated information, that is, information specified by a whole system that cannot be reduced to that specified by its parts.
What is biological consciousness?
In the vertebrates, consciousness is a dynamic, integrated, multimodal mental process entailed by physical events occurring in the forebrain. Plausibly, the neural structures and mechanisms underlying consciousness were selected during evolution because they allowed animals to plan and prepare for future eventualities.
What does the integrated information theory of consciousness state?
Initially proposed by Giulio Tononi in 2004, it claims that consciousness is identical to a certain kind of information, the realization of which requires physical, not merely functional, integration, and which can be measured mathematically according to the phi metric.
What is Phi consciousness?
Phi corresponds to the feedback between and interdependence of different parts of a system. In Consciousness, Koch equates phi to “synergy,” the degree to which a system is “more than the sum of its parts.” Phi can be a property of any entity, biological or non-biological.
What is the biological perspective and what are the key concepts associated with the biological perspective?
The biological perspective is a way of looking at psychological issues by studying the physical basis for animal and human behavior. It is one of the major perspectives in psychology and involves such things as studying the brain, immune system, nervous system, and genetics.
Is consciousness a biological function?
Consciousness is a function of living organisms, and it is unsurprising that it is adaptive, since most functions of organisms have evolved to enhance their biological fitness. In summary, the evidence that consciousness has biological value is: Consciousness is very complex.
