Homeostasis and drive theory homeostasis: a state of internal equilibrium that the body strives to maintain drive theory: physiological disruptions to homeostasis produce drives, internal tension that motivates an organism to behave in ways that reduce this tension. Incentive and expectancy theories incentives: represent environmental stimuli that pull a organism toward a goal. Freud much of our behaviour results from a battle between unconscious impulses and our defenses keeping them under control dual-instinct model.
