Answer:
stimulus generalization
Explanation:
In stimulus generalization, a stimulus acquires control over a response due to reinforcement in the presence of a similar but different stimulus. Frequently, generalization depends on elements common to two or more stimuli. An example of stimulus generalization is what is happening to Anya. When Anya drank orange juice (stimulation) she felt sick (response), so when she saw grapefruit juice, which is a stimulus very similar to orange juice, she felt sick.
