Document Summary
The three components of motivation, activation, direction and persistence. This theory posits that instincts (evolutionary behaviour that is pre-programmed into a species) drive behaviour. The drive reduction theory of motivation is similar to the instinct theory of motivation insofar that they both focus on internal factors. The point of difference is that drive theory revolves around the concept of homeostasis. The health of any living organism is optimised when the internal environment is balanced. The drive reduction theory attempts to explain motivation at a general species level e. g. , the ideal internal environment for humans and deviations away from that as a prompt for action. Similar to the instinct theory, drive reduction theory does not take individual differences into account. Arousal theory curiosity-motivated behaviours and those that are done just to cause an increase in physiological arousal, a general level of activation that is reflected in the state of several physiological systems.
