Millar’s Law

The average person can only keep 7 (plus or minus 2) items in their working memory.

Key Takeaways

1. Don’t use the “magical number seven” to justify unnecessary design limitations.
2. Organise content into smaller chunks to help users process, understand, and memorise easily.
3. Remember that short-term memory capacity will vary per individual, based on their prior knowledge and situational context.

Chunking

A process by which individual pieces of an information set are broken down and then grouped together in a meaningful whole.

Chunking can organise content to help users process, understand, and memorise easily.

Key Takeaways

1. Chunking enables users to easily scan content. It allows them to easily identify the information that aligns with their goals and process that information to achieve their goals more quickly.
2. Structuring content into visually distinct groups with a clear hierarchy enables designers to align information with how people evaluate and process digital content.
3. Chunking can be used to help users understand underlying relationships by grouping content into distinctive modules, applying rules to separate content, and providing hierarchy.
