Document Summary
Motives are the needs, wants, interests, and desires that propel people in certain directions. Many theories view motivational forces in terms of drives. Clark hull"s concept of drive was derived from walter cannon"s observation that organisms seek to maintain homeostasis a state of physiological equilibrium or stability. Drive theories apply the concept of homeostasis to behaviour. Drive an internal state of tension that motivates an organism to engage in activities that should reduce this tension. When individuals experience a drive, they are motivated to pursue actions that will lead to drive reduction. Ex. if you go without food for a while, you get hungry (discomfort), which motivates you to get food. Ex, you can walk past an ice cream shop and suddenly want to stop for ice cream, without being hungry prior. Since drive theories assume that people always try to reduce internal tension, they cannot explain this. Incentive is an external goal that has the capacity to motivate behaviour.
