Zeigarnik Effect

Zeigarnik recall

Bluma Zeigarnik (1901 – 1988) was a Soviet psychologist and psychiatrist who discovered the Zeigarnik [zy-gar-nikeffect, which states that people remember uncompleted or interrupted tasks better than completed tasks. She first studied the phenomenon after her professor, Gestalt psychologist Kurt Lewin, noticed that a waiter had better recollections of still unpaid orders. However, after the completion of the task – after everyone had paid – he was unable to remember any more details of the orders.

The advantage of remembrance can be explained by looking at Lewin’s field theory (a framework which examines patterns of interaction between the individual and the total field, or environment): a task that has already been started establishes a task-specific tension, which improves cognitive accessibility of the relevant contents. Task completion alleviates the tension. In case of task interruption the reduction of tension is impeded. Through continuous tension the content is easier accessible and it can be easily remembered.
