INTRODUCTION

English translation pending.

CORE DEFINITION

The Zeigarnik effect is the observation that people recall an unfinished or interrupted task more clearly and more durably than a completed one. Its core claim is that interruption creates an unclosed psychological tension that keeps the task active in the mind, revealing how the incomplete continues to pull at attention long after the visible work has stopped.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Deliberate pause: stop mid-task when you want the material to stick. - Pull leverage: leave a task unfinished to keep others moving toward completion. - Closure discipline: finish deliberately to release the attention a task is holding.

Anchor fast decisions

Interruption leaves the task without a completion signal, so the tension it generated has nowhere to discharge and the mind keeps returning to it. Once the task is closed, the tension releases and the detail is free to be forgotten.
