Pavlov's dog stopped salivating to the tone when the food was no longer paired with the tone. this is an example of _____.

Pavlov's dog ceased to salivate in response to the bell when it was no longer associated with food. This phenomenon is termed extinction.

The described instance illustrates extinction in classical conditioning. Classical conditioning is a learning method where an unlearned reflex response, identified as the conditioned response, is triggered by pairing a biologically significant stimulus, known as the unconditioned stimulus, with a initially neutral stimulus called the conditioned stimulus. Repeatedly presenting the conditioned stimulus without the unconditioned stimulus will result in the absence of the conditioned response, a process referred to as extinction. In this scenario, the tone serves as the conditioned stimulus, food is the unconditioned stimulus, and the dog's salivation represents the conditioned response. Thus, this instance exemplifies extinction in classical conditioning.
