Document Summary

Consciousness: our awareness of ourselves and our environment. Cognitive neuroscience: the interdisciplinary study of the brain activity linked with cognition (thinking, memory, language) 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. 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 that occur on a 24-hour cycle. Rem sleep: rapid eye movement sleep; sleep stage during which vivid dreams commonly occur. It is also known as paradoxical sleep because the muscles are relayed but other body systems are active. Alpha waves: the relatively slow brain waves of a relaxed, awake state. Sleep: periodic, natural, easily reversible loss of consciousness.
