Answer:conditioned response
Step-by-step explanation:
According to classical conditioning, the conditioned response is a learned from a previously neutral stimulus.
For example if a dog is given food daily by whistling first to call it, over time the dog will associate whistling with food , then whistling is a conditioned stimulus which is associated with unconditioned stimulus which is food.
Conditioned response is learned whilst unconditioned response occurs naturally and automatic without prior learning such as a dog salivating at the taste of it food.
