Document Summary

Consciousness - our awareness of ourselves and our environment. 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. Selective attention - the focusing of conscious awareness on a particular stimulus. Inattentional blindness - failing to see visible objects when our attention is directed somewhere. 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, a recurring sleep stage during which vivid dreams commonly occur. Muscles are relaxed but other body systems are active. Relax for 20 minutes in stage 2. Few minutes to go to 3 and then 4, brain emits delta waves which last for 30 mins. Alpha waves - the relatively slow brain waves of a relaxed, awake state.
