The closest analogue is probably connectionism: https://en.wikipedia.org/wiki/Connectionism https://en.wikipedia.org/wiki/Connectionism But then, psychology has existed for about a hundred years; physics has existed since the Greeks. "Hard" science is a useless distinction, I think. I've never heard a useful experimental procedure that can distinguish between the two. Yours in particular is very overconstrained; I don't know of a "unifying theory" for astronomy, geology, oceanography, or computer science, all of which are in my university's "college of mathematical and natural sciences," which are all presumably "hard."
