Awareness
awareness comprises a human's or an animal's perception and cognitive
reaction to a condition or event. Awareness does not necessarily imply
understanding, just an ability to be conscious of, feel or perceive.
Awareness is a relative concept. An animal may be partially aware, may be
subconsciously aware, or may be acutely aware of an event. Awareness may be
focused on an internal state, such as a visceral feeling, or on external events
by way of sensory perception. Awareness provides the raw material from which
animals develop qualia, or subjective ideas about their experience.
Researchers have debated what minimal components are necessary for animals to be
aware of environmental stimuli, though all animals have some capacity for acute
reactive behavior that implies a faculty for awareness.
Popular ideas about consciousness suggest the phenomenon describes a condition
of being aware of one's awareness. Efforts to describe consciousness in
neurological terms have focused on describing networks in the brain that develop
awareness of the qualia developed by other networks.
Neural systems that regulate attention serve to attenuate awareness among
complex animals whose central and peripheral nervous system provides more
information than cognitive areas of the brain can assimilate. Within an
attenuated system of awareness, a mind might be aware of much more than is being
contemplated in a focused extended consciousness.
When a patient goes for a surgical operation, it is desirable to temporarily
make the patient unaware. Anaesthesiologists specialise in this and a major
responsibility is to prevent awareness during the operation. This is achieved by
giving anesthetic drugs through the veins and through the lungs.
Awareness is also a concept used in CSCW. Its definition has not yet reached a
consensus in the scientific community.
