Answer:
The answer is: Classical conditioning
Step-by-step explanation:
Classical conditioning refers to the learning method that involves pairing of the conditioned stimulus and the unconditioned stimulus to produce a unconditioned response.
In this process, the conditioned stimulus is a neutral environmental stimulus, which when paired with a biologically significant unconditioned stimulus triggers an unlearned reflex unconditioned response.
In the given example, conditioned stimulus is the chocolate chip cookies, unconditioned stimulus is the smell of the cookies and the positive feeling is the unconditioned response.
