The unconditioned stimulus is the stimulus that naturally and automatically triggers a response, without any conditioning. In this example, the electric shock is the unconditioned stimulus. It naturally causes a physical response (jerk of the hand) without any conditioning. The buzzer is the conditioned stimulus as it is paired with the unconditioned stimulus (electric shock) to elicit the conditioned response (jerk of the hand). The fear of the shock and the jerking of the hands away are both conditioned responses.
