Reducing cognitive load means reducing the mental effort required to do something. Making designs easy to use and understand is part of the solution. Whether it’s digital information or walking the street, we can all do with some help by reducing cognitive load so we can process the important messages.
Jon Yablonski developed seven design principles for reducing cognitive load in relation to user interfaces in the digital world. But these are useful tips for other fields of design. The seven principles make a lot of sense and are explained simply. The principles are:
- Avoid unnecessary elements: less is more
- Leverage common design patterns: keep things familiar
- Eliminate unnecessary tasks: make it easy to stay focused
- Minimize choices for easy decision making
- Display choices as a group: to help with decisions
- Strive for readability: make it legible
- Use iconography with caution: they aren’t always intuitive
Yablonski’s website explains further the concept of cognitive load. Every time you visit a website or a new environment your brain has learn something new. You have to do two things at once – focus on learning how to get around and at the same time, remember why you are there. The mental effort required is called cognitive load. If you get more information than you can handle, the brain slows down. We can’t avoid cognitive load, but designers can help minimise it.
