Motivation process that influences the direction, persistence &vigour of goal-oriented behavior. Evolutionary psychologists propose that motivational tendencies had adaptive significance: more likely to be passed from one generation to the next o. Eventually evolving into genetically based predispositions to act in certain ways. Instinct an inherited predisposition to behave in a specific &predictable way when exposed to a particular stimulus. Homeostasis a state of internal physiological equilibrium that the body strives to maintain. 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 represent environmental stimuli that pull an organism toward a goal. Expectancy x value theory proposes that goal-directed behavior is jointly determined by. 2 factors: the strength of the person"s expectation that particular behaviours will lead to a goal &the value the individual places on that goal often called inactive value o. Explains why the same incentive may motivate some but not others.
