Document Summary
Motives: are needs, wants, interests and desires that propel people in certain direction. Drive theories apply the concept of homeostasus to behaviour. A drive is an internal state of tension that motivates an organism to engage in activites that should reduce this tension. When you experience a drive you"re motivated to pursue actions that lead to drive reduction. The drive serves to initiate behaviour but doesn"t gve direction. An incentive is an external goal that has the capacity to motivate behaviour. Expectancy-value models (atkinson and birch) of motivation are incentive theories that say you can"t always achieve your goal. 1) expectancy about one"s chance of attaining the goal. 2) the value of the desired incentive. Human motives are a product of evolution, this is why it explains motives such as affiliation, achievement, dominance, aggression and sex-drive. Most theories except evolutionary diffirentiate between biological motives and social motives. Biological needs: essentials to survive and there are 10-15 of them.
