I have been reading about Pavlovian brain conditioning and it seems that documented cases are mostly limited to motor reflexes (like conditioning an eyelid to close when hearing a tone) or taste aversion . Basically information flowing through Cerebellum and Hippocampus. Are there proofs or scientific studies about the limitations of such conditioning? Or studies about what can be associated and what not?
Let's imagine for example that a subject looks at a black neutral screen and whenever some tone is played, the screen turns bright red. After an intense conditioning would it be possible that this subject, when blindfolded would see some red when hearing that same tone?
