Document Summary

Drive theories: apply the concept of homeostasis, a drive is the internal state of tension that motivates an organism to engage in activities that should reduce this tension. Drive system example: hunger motive, drive system is the experience of discomfort. This internal tension (drive) motivates you to eat food. An incentive: external goal has capacity to motivate behaviour. Drive and incentive models of motivation often are contrasted as: push-versus pull theories. Drive theories: tension push people in certain directions. Incentive theories: emphasize how external stimuli pull people in certain directions. Drive theories the source of motivation lies: within organism. Incentive theories the source of motivation lies: outside the organism. According to expectancy-value models one motivation to pursue a particular course of action will depend on two factors: 1. Expectancy about ones chances of attaining the incentive 2. Evolutionary perspective assert: human motives and those of other specialities are products of evolution, just as anatomical characteristics are.
