Document Summary

Altered states of consciousness: sleep, hypnosis, drugs, near-death experiences. Most consciousness and system 2 is in the dorsolateral prefrontal cortex (dpfc), but it is also distributed throughout the brain. This is often referred to an emergent phenomenon. **emergent phenomenon a phe(cid:374)o(cid:373)e(cid:374)o(cid:374) that (cid:272)ould(cid:374)"t easily (cid:271)e predi(cid:272)ted from low level analysis. There is also a section of the ventromedial prefrontal cortex (vpfc) that it thought to control some aspects of consciousness, such as integrating emotions. Without it, your brain would be like skin without pain receptors, not giving you any se(cid:374)se of what you like a(cid:374)d do(cid:374)"t like, or how you feel. Divided attention happens often, and is usually tested by a dichotic listening task. Divided attention vs. cognitive resources: slower processing, cognitive blindness. The (cid:373)oder(cid:374) theory says that there"s two differe(cid:374)t (cid:272)ategories of pro(cid:272)essi(cid:374)g that goes o(cid:374) in the brain: explicit memory and cognition = conscious (ex: thinking, decision making, etc. )
