Document Summary
Motivation: a need or desire that energizes and directs behavior. Same motive, different wiring: the more complex the nervous system, the more adaptable the organism. Both humans and weav- erbirds satisfy their need for shelter in ways that reflect their inherited capacities. Human behav- ior is flexible; we can learn whatever skills we need to build a house. The bird"s behavior pattern is fixed; it can build only this kind of nest. Instinct: a complex behavior that is rigidly patterned throughout a species and is unlearned. Drive-reduction theory: the idea that a physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy the need. Drive-reduction theory: drive-reduction motivation arises from homeostasis an organism"s natural tendency to maintain a steady internal state. Thus, if we are water deprived, our thirst drives us to drink and to restore the body"s normal state.
