Document Summary
Factors energize and direct behavior toward attainment of some goal. Rationalism: reason and logic to determine actions. Mechanism: internal and external forces control our actions. Hedonism: underlying cause of all behavior is desire to seek pleasure and avoid pain. Theory of instincts: inborn biological forces make us act in certain ways at certain times. Drive: aroused state resulting from some biological need. Homeostasis: body tends to maintain constant internal environment. Sex is motivating but differs from other drives. Humans motivated to engage behaviors that increase or decrease arousal. High arousal levels motivate engagement in behaviors that lower levels. Low arousal levels motivate activities that increase arousal. Always seeking some optimal level of arousal. Nervous system tends to counteract deviation from normalcy. Base are basic physiological need; peak are highest human needs. Physiological, environmental, social factors affect feelings of hunger. Humans automatically regulate caloric intake through homeostatic system to prevent energy deficits and maintain stable body weight.
