ZeigarnikvsOvsiankina
The short answer
Zeigarnik is about remembering an unfinished task; Ovsiankina is about going back and resuming it. When researchers finally pooled the evidence, the resumption effect held up and the memory effect largely didn't — so the more famous of the two names is attached to the weaker finding.
