Document Summary
Some states of consciousness occur spontaneously: daydreaming, drowsiness, dreaming. Some states are physiologically induced: hallucinations, orgasm, food or oxygen starvation. Some are psychologically induced: sensory deprivation, hypnosis, meditation. Cognitive neuroscience: the interdisciplinary study of the brain activity linked with our mental processes. Dual processing: the principle that information is often simultaneously processed on separate conscious and unconscious tracks. Blindsight: a condition in which a person can respond to a visual stimulus without consciously experiencing it. A visual perception track enables us to recognize things and plan future actions; a visual action track guides our moment-to-moment actions. Selective attention: the focusing of conscious awareness on a particular stimulus. Inattentional blindness: failing to see visible objects when our attention is directed elsewhere. Change blindness: failing to notice changes in the environment. Circadian rhythm: the biological clock; regular bodily rhythms (for example, of temperature and wakefulness) that occur on a 24-hour cycle.
