Explanation
Answer: D - When the school bell rings, children run to the recess room. In this case, the school bell is the conditioned stimulus. In classical conditioning, a condition stimulus is a stimulus that was previously neutral (which means it did not lead to a behavior) that is now used to illicit a behavior. When a child enters school for the first time, the sound of the school bell is not associated with recess and all the fun that goes with it. After several days and weeks at school, the child is conditioned to respond to the school bell with happiness because it means that he or she will run around, play, and have snacks. The school bell, then, is the conditioned stimulus.
