Document Summary

Drive theory (hull, 1943) suggests that physiological disruptions to homeostasis produce drives, states of internal tension that motivate an organism to behave in ways that reduce this tension. Drives provide a source of energy that pushes an organism into action: example: tensions that push us to behave in a certain way, hot vs. Cold: tired vs. rested, full vs. hungry, fat vs. Criticism: does(cid:374)"t e(cid:454)plai(cid:374) (cid:449)h(cid:455) (cid:449)e keep eati(cid:374)g (cid:449)he(cid:374) (cid:449)e"re full.

Example: addiction is usually associated with incentive theory (no biological need for the drug but you want the high) Much of our behaviour results from a never- ending battle between unconscious impulses struggling for release and psychological defences used to keep them under control.
