Zeigarnik Effect:

Hello dear Steemians:

Did you notice that your mind remembers uncompleted tasks more than the completed ones?
For example: your mind keeps on repeating bits of a song you didn’t finish listening to, or goes around in circles trying to figure out how was the ending of a certain movie or a book that you didn’t finish reading. This tendency for recalling interrupted tasks better than the completed ones is called the Zeigarnik effect.

Bluma Zeigarnik, a Lithuanian Psychologist, noticed that waiters have a better recollection of complex orders before the order is served, however after the task is finished (the order is paid), they don't remember the details of that order.

Zeigarnik did a series of experiments, and her research showed that the human mind hates unfinished tasks. The unfinished task triggers Psychic Tension in you to persuade you to finish that certain task. The brain is uncomfortable as long as the task isn’t finished. The tension can only be eased if you finish it.

To be more effective and use Zeigarnik effect to your advantage, Scientists suggest that when you have a task in your mind, you should stop everything you are doing and start writing a plan of how you can approach it. Or, if you have a few thoughts and tasks in your mind, it is better to write them down, “to-do list.”, to empty your head and decrease anxiety and stress.
