Answer:The Drive-Reduction Theory
Explanation:
The Drive-Reduction Theory, a principle first proposed by the psychologist Clark Hull in 1943 to explain the situations under which learning can take place
It describes an organism's reaction to a situation where his physical needs are questioned or challenged. Such organism can develop new responses when it is motivated by a need and strives to meets that need. In a nutshell, it means that Learning depends on how an organism alleviates or satisfies it's drive;for example Lara knows to get a glass of water because she gets the feeling of being thirsty which motivates her to reduce her thirst by drinking water- An example of drive reduction theory.
