Consciousness and Unconsciousness
Consciousness is one of the most basic concepts of psychology (as I understand psychology). No other psychological phenomena exist unless the person is conscious, at least to some degree.
The words consciousness and awareness are often used interchangeably, and I will use them this way also. Arousal and alertness are two other words often used as meaning the same thing as consciousness.
