Lara's mouth is dry and she realizes that she has not had anything to drink all morning. The water level in her cells has dropped and she feels thirsty. Watching people drink large glasses of soda is upsetting her and, at the next opportunity, she will take an extra-large drink. Which concept can be used to explain why Lara is motivated to get a drink?

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.

According to this theory, there are physiological needs (in this case water), that occurs in an organism that creates an unrest( need for water) and motivates the organism to satisfy the need to reduce such disturbances. (ie to drink water).

The Drive-Reduction theory

Explanation:

The theory that learning is dependent on the alleviation or satisfaction of a drive; more specifically, that an organism will acquire new responses only when it is motivated by a need and receives a reward that meets that need.
