Document Summary

The belief that internal demands on the body serve as a source of motivation is related to homeostasis. A desired point or set point is a condition crucial for life, comfort, or safety. The process ends when the discrepancy reaches 0. Deviation from set point creates a physiological need. Physiological need: discrepancy between set point and actual physiological state, e. g. , drop in blood glucose below a set point or level of iron level in blood is below set point. Incentives that aid in reducing a need or in restoring homeostasis increase pleasure and we are therefore motivated toward them. Judged as unpleasant and avoided if they increase the discrepancy in homeostasis.
