Document Summary
Three approaches for understanding cognition: physical symbol systems: old fashioned ai, connectionism (nn): non-symbolic approach to information processing, embodied cognition: emphasizes the role of body and environment. Do people lose consciousness when they fall asleep: conscious of dreams (often feel like intense conscious experiences) Brain waves in rem sleep are similar to those in waking state. People in comas don"t seem to have consciousness: some have reported to have conscious awareness even when apparently unresponsive. Overly simple definition: a person is conscious, in this sense, if he or she is in a generalized condition of alertness or arousal: being awake rather than asleep or in a coma . That small inner voice that is always present . Being aware of a particular external stimulus, such as an obstacle that you come against, or of a mental state such as a memory or emotion .
