Document Summary
Motives are the needs, wants, interests, and desires that propel people in certain directions, propel us to achieve important goals. This approach to understanding motivation was explored most fully by clark hull in the 1940s and 1950s (madsen, 1968). Drive theories apply the concept of homeostasis a state of physiological equilibrium or stability, to behaviour. A drive is an internal state of tension that motivates an organism to engage in activities that should reduce this tension. Drive reduction action that results in restoration of physiological equilibrium (eat to reduce hunger etc) Drive theories have been very influential, and the drive concept continues to be widely used in modern psychology. However, drive theories cannot explain all motivation (berridge, 2004).

(cid:863) An incentive is an external goal that has the capacity to motivate behaviour. Drive and incentive models of motivation are often contrasted as push-versus-pull theories.
