Which type of response is emotional, innate, and not learned?

• A. Unconditioned Stimulus
• B. Unconditioned Response
• C. Conditioned Response
• D. Conditioned Stimulus

Answer: (B)

An unconditioned response is an automatic, reflexive reaction that occurs without learning. It’s emotional and innate because it happens in response to an unconditioned stimulus without any prior training. For example, a dog salivating at food is an unconditioned response to the food itself. The other terms describe things involved in conditioning: an unconditioned stimulus is the thing that naturally triggers the response, a conditioned stimulus is a neutral cue that becomes associated with the stimulus, and a conditioned response is the learned reaction to that cue after pairing. So the described type of response is the unconditioned response.
