Answer:
c. The researcher tests several bells that sound very similar to the original bell, and the dog salivates.
Step-by-step explanation:
Stimulus generalization in the most simplest of explanation is the tendency to respond to a stimulus that is only similar to the original conditioned stimulus with the conditioned response. In this instance, the dog salivates to another bell that sounds almost similar to the original bell. It is able to generalize and see that this bell is similar enough to some other bell that was also able to evoke a condition response. The dog is able to recognize the bell, which is different in frequency but same in note and tone and salivates. Dogs, like humans, hear sounds the same way that we do.
