==Drive-reduction theory==
[[Drive theory]] grows out of the concept that people have certain biological drives, such as hunger and thirst. As time passes, the strength of the drive increases if it is not satisfied (in this case by eating). Upon satisfying a drive, the drive's strength is reduced. Created by [[Clark Hull]]  and further developed by [[Kenneth Spence]], the theory became well known in the 1940s and 1950s. Many of the motivational theories that arose during the 1950s and 1960s were either based on Hull's original theory or were focused on providing alternatives to the drive-reduction theory, including Abraham Maslow's hierarchy of needs, which emerged as an alternative to Hull's approach.<ref>{{cite web |url = http://psychology.about.com/od/motivation/a/drive-reduction-theory.htm |title = How Does Drive Reduction Theory Explain Human Motivation? |access-date = 2020-12-04 |archive-date = 2015-12-22 |archive-url = https://web.archive.org/web/20151222114008/http://psychology.about.com/od/motivation/a/drive-reduction-theory.htm  }}</ref>

Drive theory has some intuitive validity. For instance, when preparing food, the drive model appears to be compatible with sensations of rising hunger as the food is prepared, and, after the food has been consumed, a decrease in subjective hunger.<ref>{{cite book |last1 = Kamlesh |first1 = M.
