If you’re talking about the creativity that works within a paradigm, then chronological age doesn’t matter—it’s only the amount of time that you’ve spent studying the field that matters. A person who enters a field at 50 shows a similar career trajectory than a person who enters it at 20.
If you’re talking about paradigm-busting creativity, then I’m not aware of other studies that would have made the inside/outside-paradigm distinction. (Which isn’t to say that they might not exist, of course.)
