In a study, each trial involves administering a drop of lemon juice
to the participant's tongue and measuring the participant's level of
salivation.
So this scenario specifically should trigger you to think: "Ok so the researcher adds lemon juice OVER TIME and is measuring salivation... why? because they want to see how the lemon juice either increases or decreases salivation" - This sounds like a phenomena that occurs when the stimulus is not attenuated/produce a responsive reaction.
As more trials are conducted, the researcher finds that
the magnitude of salivation declines. (Yep so this confirms what we thought earlier).
After a certain point, the
researcher switches to administering lime juice. This researcher is
most likely studying which process?
Although its not explicitly said what lime juice does, I can see why you think it could be generalization bc of the similarity in the lime vs lemon juice. Stimulus generalization often involves conditioning the stimulus during the process of conditioning and doesn't involve the "switch"
For example, imagine that parents punish their son for not cleaning his room. He eventually learns to clean up his messes to avoid punishment. Instead of having to relearn this behavior at school, he applies the same principles he learned at home to his classroom behavior and cleaned up his messes before the teacher can punish him.
The better answer is habituation and dishabituation bc of the process mentioned above (the magnitude declining) and dose-response manipulated variable.
