The self-model is the central concept in the theory of consciousness called the self-model theory of subjectivity (SMT). This concept comprises experiences of ownership, of first person perspective, and of a long-term unity of beliefs and attitudes. These features are instantiated in the prefrontal cortex.
the first-order and higher-order states are part of the same whole, and the whole complex is what becomes conscious. [1] An example of the second, "part-whole" self-representational theory is Vincent Picciuto's "quotational theory of consciousness" in which consciousness consists of "mentally quoting" a first-order perception. [4]
Rather than attempting to cover all the aspects of consciousness (self-awareness, thought, imagination, perception, etc.), Crick focuses on the primate visual system and breaks down the prerequisites for conscious experience into several broad subconditions, including some sort of short-term memory and attention mechanism. The book then delves ...
The theory suggests that the brain in primary states such as rapid eye movement (REM) sleep, early psychosis and under the influence of psychedelic drugs, is in a disordered state; normal waking consciousness constrains some of this freedom and makes possible metacognitive functions such as internal self-administered reality testing and self ...
Consciousness is an ambiguous term. It can be used to mean self consciousness, awareness, the state of being awake, and so on. Chalmers uses Thomas Nagel's definition of consciousness: "the feeling of what it is like to be something." Consciousness, in this sense, is synonymous with experience. [31] [27]
So-called "broad" naturalists that see consciousness as an "emergent" non-physical property of complex brains would agree with Lewis that different levels or types of causation exist in nature, and that rational inferences are not fully explainable by nonrational causes. [4]
While other theories assert that consciousness emerges as the complexity of the computations performed by cerebral neurons increases, [4] [5] Orch OR posits that consciousness is based on non-computable quantum processing performed by qubits formed collectively on cellular microtubules, a process significantly amplified in the neurons.
Part 1 reviews the strengths and weaknesses of all currently dominant theories of consciousness, in a form suitable for undergraduates, postgraduates and researchers, focusing mainly on dualism, physicalism, functionalism and consciousness in machines. Part 2 gives a new analysis of consciousness, grounded in its everyday phenomenology, which ...
