Phi; the symbol used for integrated information. Integrated information theory (IIT) proposes a mathematical model for the consciousness of a system. It comprises a framework ultimately intended to explain why some physical systems (such as human brains) are conscious, [1] and to be capable of providing a concrete inference about whether any physical system is conscious, to what degree, and ...
Behavioral measures of primary consciousness can be either objective or subjective. Regarding objective measures, knowledge is unconscious if it expresses itself in an indirect test. For example, the ability to pick which item might come next in a series can indicate unconscious knowledge of regularities in sequences.
An altered level of consciousness is any measure of arousal other than normal. Level of consciousness (LOC) is a measurement of a person's arousability and responsiveness to stimuli from the environment. [1] A mildly depressed level of consciousness or alertness may be classed as lethargy; someone in this state can be aroused with little ...
[1] [2] It is contrasted with the "easy problems" of explaining why and how physical systems give a (healthy) human being the ability to discriminate, to integrate information, and to perform behavioral functions such as watching, listening, speaking (including generating an utterance that appears to refer to personal behaviour or belief), and ...
Pronounced lack of alertness is an altered level of consciousness. States with low levels of alertness include drowsiness . The word is formed from "alert", which comes from the Italian all'erta (on the watch, literally: on the height; 1618).
Secondary consciousness is an individual's accessibility to their history and plans. The ability allows its possessors to go beyond the limits of the remembered present of primary consciousness. [1] Primary consciousness can be defined as simple awareness that includes perception and emotion. As such, it is ascribed to most animals.
The Glasgow Coma Scale [1] (GCS) is a clinical scale used to reliably measure a person's level of consciousness after a brain injury. The GCS assesses a person based on their ability to perform eye movements, speak, and move their body. These three behaviours make up the three elements of the scale: eye, verbal, and motor.
Autonoetic consciousness is the human ability to mentally place oneself in the past and future (i.e. mental time travel) or in counterfactual situations (i.e. alternative outcomes), and to thus be able to examine one's own thoughts. One's sense of self affects their behavior, in the present, past and future.
