Document Summary
Motivation process that influences the direction, persistence, and vigour of goal-directed behaviour. View inspired by darwin that instincts motivate much of our behaviour. Key to motivation = adaptive significance of behaviour. Homeostasis a state of internal physiological equilibrium that the body strives to maintain. Hull"s drive theory of motivation physiological disruptions to homeostasis produce drives, states of internal tension that motivate an organism to behave in ways that reduce this tension. Ie hunger results from tissue deficit (lack of food) motivates us to eat. Hull says ultimate goal of motivation = to reduce drives. Applies to the regulation of hunger, thirst, body temp, weight and sleep. Incentives environmental stimuli that pull an organism toward a goal: ex: a good grade, stimuli with high incentive value can motivate behaviour, even without. Biological need: ex: drug use motivated by incentive value of drug"s effect (not to escape withdrawal)
