Document Summary
All of the processes that initiate, direct, and sustain behavior. Motives are needs or desires that direct or energize our behavior. When motives are internal they push us to act call these drives. When motives are external (or outside of us) we call them incentives they pull or entice us to act. We don"t just run, we run to something . We don"t reach, we reach towards something. Homeostasis: stable internal equilibrium, temperature control, reflexive, involuntary, supplement, voluntary behavior. How does homeostasis work: autonomic nervous system, sympathetic, parasympathetic. These systems control the compensatory mechanisms: hypothalmus. Primary drive stems from unlearned motives to satisfy biological needs. Satisfied through: reflexive compensatory mechanisms, coupled with directed behavior. Internal cues: motivate hunger by stimulating the hypothalamus in the brain, receptors from stomach and intestines and liver. External cues: motivate hunger when we see, smell or taste foods that we like.
