+An **Unconditioned Response** is a natural, automatic reaction to a stimulus that occurs without prior learning. It is an innate, unlearned behavior, like salivating at the sight of food, distinct from a [Conditioned Response](/wiki/conditioned_response). This involuntary reaction is always elicited by an [Unconditioned Stimulus](/wiki/unconditioned_stimulus).
