jpetrovic [What is drive reduction theory?]
Line 17: Line 17:
 Hull's theory was mostly orientated on S-R relationship and reinforcement. If a S-R relationship is followed by a reduction of the drive, the probability of same prior response on similar situations in the future increases. S-R relationship (**//habit strength//​**) becomes stronger through the number of **reinforcements**. Biological needs were according to Hull //primary drives//, but he also believed there are //secondary drives// (learned drives), which refer to situations associated with reduction of primary drives. That means a neutral stimulus can have primary drive characteristics,​ because it is capable of eliciting responses similar to those caused by primary drive. ​ Hull's theory was mostly orientated on S-R relationship and reinforcement.

-In order to offer a full, scientific explanation of learning, Hull developed a **formula**((Formula was retrieved from [[http://​fates.cns.muskingum.edu/​~psych/​psycweb/​history/​hull.htm|Schrock,​ J. Psychology History: Clark Hull]], but different forms of the formula appear in defferent sources like [[http://​webspace.ship.edu/​cgboer/​beh.html|Boeree,​ G.

Hull's Theory.]])) in which he tried to mathematically explain and **predict a likelihood of behavior**. This formula measures **habit strength** defined as the strength of the S-R bond. This bond represents learning.
