Document Summary

In psychology is is the moment ot moment awareness of ourselves and the environ- ment. Views the conscious and unconscious as working together not as in con- stant conflict with each other like the psychodynamic approach. Controlled processing - requires voluntary use of attention and conscious effort. Automatic processing - activities can be performed with little of no con- scious effort. Ex. learning to type, use utensils eat. More practice leads to increased performance and brain regions involved in conscious thought become less active. Stages of sleep: stage 1 light sleep may experience body jerks", stage 2 sleep deepens - muscles more relaxed - harder to awaken. Delta waves: stage 4 delta waves dominate pattern. High arousal (heart rate, breathing, brain wave activity) Rem sleep paralysis difficult for voluntary muscles to contract. Sleep deprivation: pitcher & bradley (1996) studied sleep deprivation, short term sleep deprived (up to 45 hours without sleep)
