The screech became a conditioned stimulus (CS) because it was a neutral stimulus that, after being paired with the car crash (an unconditioned stimulus), now elicits a response. Her anxiety in response to the screech became the conditioned response (CR), as it is the learned response to the conditioned stimulus.
