If a child covers her ears when seeing fireworks, before hearing the sound of them, seeing the fireworks would be the conditioned

Hello, the answer that best fits this sounds like “Conditioned Response”. The stimulus would be the fireworks, and the conditioned response or learned response would be the child covering her ears. She’s learned how loud they sound and in response to that she’s aware of when they are about to put and covers her ears. Hope this helped.
