6 laws every UX/UI Designer should know

Jakob’s Law:

Users spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know.

Example: The user interface of vertical video apps

Serial Position Effect

Users have a tendency to best remember the first and last items in a series.

Example: Navigation Bar

Zeigarnik Effect

People remember uncompleted or interrupted tasks better than completed tasks.

Example: Progress Bars & Indicators

Von Restorff Effect

When multiple similar objects are present, the one that differs from the rest is most likely to be remembered.

Example: The “Premium Plan” is emphasized to users

Law of Common Region

Elements tend to be perceived into groups if they are sharing an area with a clearly defined boundary.

Example: Printing interface & side navigation bars
