It's unlikely that it's significantly Pavlovian because reflex is typically taught with blunt reward or punishment schemes, which isn't much like the kind of training most get. Also, you'd expect reflex to respond more to superficial components than deeper principles like visual harmony (though my judgement isn't free superficiality in my judgement and others'). Similarly, you'd expect a reflexive effect to be strongest when seeing conditioned stimuli, i.e. the exact art I learned about, but it's frequently much stronger when seeing something new. Beauty isn't "there" in the object to in the same way mass or volume is there; it's contingent on human perception. Beautiful things trigger similar effects in a huge variety of people, perhaps universally (though being attentive to conscious of those feelings doesn't come automatically). So it seems meaningful to discuss what's beautiful and what's not, though skepticism about any single individual's or culture's standards of beauty is warranted.
