| 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.
