Abstract
Zeigarnik showed that people remember interrupted or unfinished tasks better than completed ones: an unresolved intention sustains a “quasi-need” tension that keeps the task active in memory until it is closed. The finding — the Zeigarnik effect — anchors why open loops occupy attention.
Zeigarnik, B. (1927). Psychologische Forschung, 9, 1–85.
Key findings
- Interruption boosts recall — Unfinished tasks were recalled far more often than finished ones.
- Tension of the open loop — An unmet intention holds a residual tension that keeps the task mentally available.
- Closure releases it — Completing (or formally cancelling) the task discharges the tension and recall advantage.
When to open this
Open alongside Weekly energy budget when you need the classic basis for why unclosed commitments quietly drain attention.
