PSY 150 Lecture Notes - Lecture 3: Slow-Wave Sleep, Sleep Paralysis, Beta Wave
Document Summary
Consciousness: the combination of our moment by moment experiences of the. Levels of consciousness: subliminal perception when our senses are processing information, but we are not aware of it. Researchers use people who have had brain surgery to learn more about consciousness. The two halves are completely isolated -- split brain. Just as the brain has been split in two, so has the conscious mind. By contrast, in split-brain patients, the hemispheres are separated, so communication between the hemispheres cannot take place. This split allows psychologists to separately test the functions of the two hemispheres. Left hemisphere: better with language, processes right visual field information, and controls right side body movements. Circadian rhythm - the biological cycles for our regular, daily patterns. Stage 1 drifting off to sleep (i. e. falling sensation) Stage 2 breathing more regular, less sensitive to stimulation (k-complex burst = asleep) Stage progression to deep, slow wave sleep (i. e. hard to wake, disoriented when awake)
