i like to separate it between visualizing something, and conceptualizing something, because if someone says a visualize a sphere, you know what a sphere is, you simply don’t need to visualize it in order to conceptualize what it should look like, thus leading to a “pseudo image”

but if someone were to say visualize the tread pattern of an all weather tire, you probably wouldn’t be able to do that very well, since you likely don’t have a very solid conceptual understanding of what it looks like.
