Document Summary

The nature of consciousness consciousness awareness of internal/external stimuli. Variations in awareness and control: mind wandering experience of task-unrelated thoughts two types; controlled (intentional thought) and automatic (unintentional thought) Unconscious thought effects: unconscious thought theory decisions made by the unconscious may be better than decisions from the conscious, conscious thought (thought with attention) is constrained by capacity; unconscious thought (inattentional thought) does not have same constraint. Biological rhythms and sleep: biological rhythms pe(cid:396)iodi(cid:272) flu(cid:272)tuatio(cid:374)s i(cid:374) ph(cid:455)siologi(cid:272)al fu(cid:374)(cid:272)tio(cid:374)i(cid:374)g; (cid:862)(cid:271)iologi(cid:272)al (cid:272)lo(cid:272)k(cid:863) Realigning circadian rhythms: method of exposing bright light on shift workers have shown positive effects; improves sleep quality and alertness. The sleep and waking cycle: electromyograph (emg) device that records muscular activity and tension, electrooculography (eog) device that records eye movements. Repeating the cycle cycle repeated about 4 times during a night: rem stage gets progressively longer (peaks at 40-60 minutes) while nrem stages get progressively shorter.
