Document Summary
It is subjective (to the environment), dynamic (ever-changing), and self-reflective. It is the driving force of behaviour (i. e. iceberg theory). Views the conscious and unconscious as working together, not in constant conflict with each other like the psychodynamic approach. Controlled processing: requires voluntary use of attention and effort. Automatic processing: activities can be preformed with little or no conscious effort (e. g. walking, breathing, typing, using utensils). Morning people go to bed earlier and wake up earlier. Their alertness peaks earlier in the day and they perform better in morning classes. Stage two sleep deepens, muscles more relaxed, harder to awaken. Sleep spindles (longer and tighter together waves of sleep). Stage four delta waves dominate pattern ( slow-wave sleep ). Rem sleep rapid eye movements, high arousal (heart rate, breathing, brain wave activity), paralysis (difficult for voluntary muscles to contract), and dreaming. Pilcher & bradley (1996) divided people into groups. Short-term sleep deprived: up to 45 hours without sleep.
