Document Summary

A process that influences the direction, persistence, and vigor of goal-directed behavior. Darwin"s theory of evolution inspired early psychological views that instincts motivate much of our behavior. Vast majority of data supports darwin (e. g. , izard, 1977)in. An inherited predisposition to behave in a specific and predictable way when exposed to a particular stimulus. Found universally among all members of the species. However, human instinct theory has little evidence to support. A state of internal physiological equilibrium that the body strives to maintain. Physiological disruptions to homeostasis produce drives (states of internal tension that motivate an organism to behave in ways that reduce this tension. Reducing drives is the ultimate goal of motivated behavior. Environmental stimuli that pull an organism toward a goal. Incentive theory emphasizes the pull of external stimuli and how stimuli with high incentive value can motivate behavior, even in the absence of biological need.
