Document Summary
Motivation: process that influences direction, persistence, and vigour of goal directed behaviour. Instinct: inherited predisposition to behave in a specific and predictable way when exposed to a particular stimulus. In ancestral past, motivational tendencies that had adaptive significance were more likely to be passed from one generation to the next, eventually evolving into genetically based predispositions to act in certain ways. To produce survival advantages, like shared resources and protection against predators. Homeostasis: state of internal psychological equilibrium that the body strives to maintain. Drive theories propose that tissue deficits create drives, such as hunger, that motivate or push an organism from within t o reduce the deficit and restore homeostasis. Incentive: environmental factors that pull people toward a goal. Ex: a good grade is incentive for studying. Incentive theories focus on external stimuli that motivate behaviour; high incentive value can motivate behaviour, even in ab sence of biological need.
