Answer:
The given situation is an example of <u>extinction</u><u> in classical conditioning.</u>
Explanation:
Classical conditioning is a learning process in which an unlearned reflex response, called the conditioned response, is induced by pairing a biologically potent stimulus, called unconditioned stimulus, with a originally neutral stimulus, called conditioned stimulus.
If the said <u>conditioned stimulus is repeatedly introduced in the absence of the unconditioned stimulus, then it will not induce the conditioned response</u>. This is known as the extinction of the conditioned response.
In the given example,<u> tone is the conditioned stimulus, food is the unconditioned stimulus and the dog salivating is the conditioned response.</u>
<u>Therefore, the given situation is an example of extinction in classical conditioning.</u>
