Cognitive Load

Reduce the mental work around the task.

01 / UNDERSTAND

The idea

An interface consumes attention when people interpret labels, remember information and work out what happens next. Remove avoidable effort while preserving the information needed to make a sound decision.

Working memory has limits. A demanding game can be enjoyable because the player wants the challenge; an administrative form may place similar demands on someone with no interest in the complexity. The design question is which mental work serves the user’s goal, and which work merely comes from using the interface.

02 / RECOGNISE

See it in real products.

Examples of how the principle can appear in an interface.

UberEXAMPLE 01

Offer a simpler way to use the product

Uber’s Simple Mode reduces the home screen to clearer trip actions and larger controls. It gives people an alternative to a busier mix of services and suggestions.

NoteCircleEXAMPLE 02

Remove the blank-page decision

NoteCircle provides a sample task that can be saved into today’s list. A newcomer can learn the interaction before thinking of real content to enter.

03 / CONNECT

Why it matters.

Excess mental work can slow tasks, reduce input quality and increase frustration. A manageable challenge may still be enjoyable when it serves a goal the person values.

Possible influences to investigate, rather than guaranteed outcomes for every product.
