What Is Motivation?

  • Motivation is an internal process that makes a person move toward a goal.
  • Motivation may be extrinsic, intrinsic, or both.
  • Drive reduction theories of motivation suggest that people act in order to reduce needs and maintain a constant physiological state.
  • Abraham Maslow proposed that there is a hierarchy of needs and that people pay attention to higher needs only when lower ones are satisfied.
  • Needs may be innate or learned. Learned needs are determined by values. Both innate and learned needs are influenced by society and culture.

Hunger

  • A genetically influenced set point may allow people to keep their weight constant.
  • The lateral hypothalamus and the ventromedial andparaventricular nuclei of the hypothalamus play key roles in regulating hunger.
  • The digestive system and hormones such as insulin and leptin also regulate hunger.
  • Environmental influences on hunger include availability of foods,preferences, habits, memory, stress, andcultural attitudes.

Sexual Drive
