Answer:
Stimulus generalization
Explanation:
Stimulus generalizationis is when a subject responds to a stimulus or a group of stimuli similar but not identical to the original situation. For example the dog salivating at a slightly higher or lower pitch not only to the exact tone is a stimulus that is similar but not the original. The animal responds to the similar stimulus in the same way it would to the conditioned stimulus.
You need a variable. If something happens once it could just be chance. Like if you got a lottery ticket and won, it would just be chance. Not the thing that happens the most.
