Document Summary

Motivation: process that influences the direction, persistence, and vigour of goal-directed behaviour. Instinct: an inherited predisposition to behave in a specific and predictable way when exposed to a particular stimulus. Homeostasis: a state of internal physiological equilibrium that the body strives to maintain: response system (restores equilibrium, control centre (receives information from the sensors and activates the response system) Drive theory: physiological disruptions to homeostasis produce drives, states of internal tension that motivate an organism to behave in ways that reduce this tension. Incentives: environmental stimuli that pull an organism toward a goal (e. g. a good grade would be an incentive to a student). Extrinsic motivation: performing an activity to obtain an external reward or avoid punishment. Intrinsic motivation: performing an activity for its own sake-because you find it enjoyable or stimulating. Overjustification hypothesis: giving people extrinsic rewards to perform activities that they intrinsically enjoy may overjustify that behaviour and reduce intrinsic motivation.
