The unconditioned stimulus is the original stimulus that triggers an unlearned response, in this case, Luke kissing Laura. The unconditioned response is the natural response to the unconditioned stimulus, Laura's increased heart rate. However, when Old Spice became associated with Luke through repeated pairing with the unconditioned stimulus (Luke kissing Laura), it became a conditioned stimulus. Therefore, Laura's increased heart rate when she smelled Old Spice is a conditioned response.
