Theories of Motivation •Drive: A state of unrest or irritation that energizes one behavior or another until one of them removes the irritation. •Drive Reduction Theory (1940s-1950s) asserts that people are only motivated by a desire to reduce irritation. Problem: Once all needs are filled, people are still motivated. •Homeostasis: The maintenance of an optimal level of biological conditions within an organism. Theory: We desire homeostasis. Problem: We plan for the future: e.g. heavy brakfast when we aren’t hungry. •Revised Description: allostasis: The maintenance of an optimal level of biological conditions that vary with an individual’s needs. •Incentives: external stimuli that pull us toward certain actions. •Most motivated behaviors are driven by a drive and an incentive: e.g. you eat because you are hungry (drive) and you see delicious food (incentive.) •Intrinsic Motivations: Performing an act for it’s own sake: Reading a book. •Extrinsic Motivations: Done for a reward: e.g. studying for a test. The Physiology of Hunger and Satiety •Hunger is regulated short-term by signals from stomach (distension) and hormones. Familiar foods also trigger signals of approximate amount of nutrition per mouthful.
