Answer 1

CS: Conditional Responses

Step-by-step explanation:

Conditional response means to inculcate a desired behavior in a subject of interest.

Foe example, in above example, researchers conditioned her to blink in response to a sound that signaled the delivery of a puff of air directed toward her face. In this application of classical conditioning, the sound was a conditional response.

Now the behavior (eye blink) in response to a sound is inculcated in Mrs. Webster. This was a conditioned response.

Answer 2

C. CS.

Step-by-step explanation:

A psychologist named Ivan Pavlov has proposed the term classical conditioning by experimenting with dogs. While experimenting he has given five steps that are involved in the classical conditioning process i.e, the US, UR, CS, CR, and NS.

Conditioned stimulus: The term conditioned stimulus in classical conditioning is defined as a formerly neutral stimulus that is being associated with the US i.e, the unconditioned stimulus and hence it gives rise to a conditioned response i.e, the CR.

In the question above, In the application of classical conditioning, the sound was a CS i.e, conditioned stimulus.
