Document Summary
Rene descartes i think, therefore i am. Self-reports (what do you think about something, how do you feel about something?) Took four chimpanzees and put a mirror in front of them and seeing if they were aware that the figure in the mirror were themselves. Put a red mark on their head and tested if they would touch their head and not the mirror they are self aware. Stimulants (euphoria), tranquilizers (calmness), hallucinogens(altered perceptions), opiates (sedation/calmness), barbiturates (loss of consciousness) Sigmund freud - our consciousness is affected by things below our sense of consciousness. 5% conscious brain activities, 95% subconscious brain activity. Most scientists agree that we sleep because we have inherited nervous systems that induce us to sleep for a portion of every day. So sleep is said to be on a circadian rhythm (any biological cycle that repeats every 24 hours) Short sleep deprivation: affects your mood and emotion.
