Therefore, it might be wrong to call instincts or reflexes prolepses.
I would emphasize the "might" there, as there may be a relationship of some kind (at the very least, both seem to be related to something that is present at birth, prior to all experience through ears and eyes and the rest). However what I think would definitely be wrong would be to "equate" the two, because they pretty clearly are not exactly the same in all respects and functions.
