Freud wasn't a scientist, he was a philosopher and clinician who talked about things that are now considered part of psychology. If you limit things to psychologists who were clearly scientists then things have pretty much been converging. There have been a few big shakeups particularly with regards to the rise and fall of behaviorism, but it is a bit of a stretch to call them "pretty much completely reject[ing] the findings of the previous generation" and similarly large shifts have occurred in other fields (c.f. phlogiston theory).
