The Zigarnic Effects in Video Games

In video games, you see the zigarnic effects show up in quest logs and progression indicators towards badges. The idea is that unfinished tasks or unreached goals creates sort of an internal psychological tension that preoccupies us with the task. And we remember it. It's easier for us to recall things about that incomplete olincomplete task from memory. Completing that task releases the tension, makes us happy and dismisses the information. We no longer have need to recall it from memory, so we don't. You know, you'll have literal progress bars, and i'll show you percentages tour you know, collectables completed or areas explored, or what have you.
