-Drive reduction theory was introduced in 1930s by an eminent American psychologist [[http://​www.newworldencyclopedia.org/​entry/​Clark_L._Hull|Clark Hull]], whose works were **influenced by other behaviorists** like [[http://​www.ivanpavlov.com/​|Ivan Pavlov]], [[http://​www.muskingum.edu/​~psych/​psycweb/​history/​thorndike.htm|Edward Thorndike]] and [[http://​www.muskingum.edu/​~psych/​psycweb/​history/​tolman.htm|Edward Tolman]], but also by [[http://www.google.hr/​url?​sa=t&​source=web&​cd=1&​ved=0CB0QFjAA&​url=http%3A%2F%2Fhr.wikipedia.org%2Fwiki%2FCharles_Darwin&​rct=j&​q=charles%20Darwin&​ei=0HJXTte6IOjZ4QScgZmwDA&​usg=AFQjCNGi2OrPOZzy4GV4X6wrdQfXzOjqpg&​cad=rja|Charles Darwin]]'​s theory of evolution.(([[http://​www.lifecircles-inc.com/​Learningtheories/​behaviorism/​clarkhull.html|Cooper,​ S.

Another area of Hull's interest was hypnosis research. He conducted a number of laboratory experiments in which he finally showed that hypnosis and sleep are two completely separate states.(([[http://​books.google.hr/books?​id=6eK_bwAACAAJ&​dq=Hypnosis%20and%20Suggestibility%3A%20An%20Experimental%20Approach&​source=gbs_book_other_versions|Hull, Clark H.

-Like other behaviorists,​ Hull was only interested in **overt behavior**, yet he did not deny existence of cognitive factors like ideas, prior knowledge, intelligence,​ insight and values. He excluded this factors from his theory since they could not be scientifically measured.(([[http://​www.lifecircles-inc.com/​Learningtheories/​behaviorism/​clarkhull.html|Cooper,​ S.

 In his theory, Hull tried to explain behavior and learning through drive reduction. **"​Drive"​** presents a **stimulus** in form of a biological need like hunger, thirst, cold or sexual interest. It is a state of need, when a living organism feels the needs to behave in certain way to reduce the need and restore the optimal biological state. The drive therefore **results in behavior** in order **to achieve certain goal** or satisfy the need. If the goal of the drive is achieved, the **drive is reduced** and an optimal state is restored. The **drive reduction** here **is a reinforcer**,​ strengthening the connection between the drive and behavior.(([[http://​www.psywww.com/​intropsych/​ch09_motivation/​hulls_theory.html|Dewey,​ Russ.
