Document Summary

A need is any condition within the person that is essential and necessary for life, growth, and well-being. When needs are nurtured and satisfied, well being is maintained and enhanced. If neglected or frustrated, the need"s thwarting will produce damage that disrupts biological or psychological well being. Motivational states therefore provide the impetus to act before damage occurs to psychological and bodily well being. Thirst: thirst is the consciously experienced motivational state that readies the person to perform behaviors necessary to replenish a water deficit. Hunger: hunger and eating involve a complex regulatory system of both short-term (glucostatic hypothesis) & long-term (lipostatic hypothesis, including set- point theory) regulation. Sex: sexual motivation rises and falls in response to a host of factors, including hormones, external stimulation, external cues (facial metrics), cognitive scripts, sexual schemas, and evolutionary process. Two different kinds of thirst: osmotic thirst a thirst resulting from eating salty foods. Each kind of thirst motivates different kinds of behaviors.
