Functions of consciousness
Consciousness is a supremely functional adaptation system (Bernard Baars), with particular importance for prioritization of alternatives, problem solving, decision making, brain processes recruiting, action control, error detection, planning, learning, adaptation, context creation, and access to information.
Consciousness is a part of a survival system (Antonio Damasio) allowing planning response; awareness of self which allows a concern for one's own survival, increases the drive to survive. Consciousness is involved in behaviour.
The normal, complete awareness is an ability to be conscious of, feel or perceive. It is a condition of having knowledge or perception of a situation or fact.
Concept of the integration
The phenomenal states integrated neural activities and information-processing (that would otherwise be independent, unspecified the information) are integrated in consciousness and without consciousness.
Some information is disseminated and combined without consciousness (intersensory interactions, neural activity related to vegetative functions, reflexes, unconscious motor programs, low-level perceptual analyses, etc.).
Concept of collective consciousness
The concept of collective consciousness is essential for organization of human, social relations, accelerating drive of human race to explorations, cognition, understanding and technological progress.
The concept includes some features of collective consciousness (collective self- concepts) and collective intelligence.
