Document Summary

Describe the terms motivation and drive and differentiate between regulatory and nonregulatory drives. Describe the reward systems and mechanisms in the brain. Explain the central state of theory of drives. Evaluate theories of motivation for their ability to explain how and why we eat. Motivation the desires (internal and external), needs, and interests that arouse and activate an organism to move toward a specific goal. Drive reversible internal conditions that orient individuals toward specific types of goals. Regulatory drive hunger, thirst, thermoregulation, and sleep;helps to maintain physiological homeostasis and are needed for our immediate survival; related to specific areas of the hypothalamus. Nonregulatory drive indirectly fulfills an evolutionary purpose; reproduction, safety or cooperation are not required for our immediate survival, but do promote our long term survival and the survival of our offspring. Motivational states direct an animal to act and direct behaviour toward a goal.
