Miller's number is a psychological theory that states that the human working memory is only capable of processing a limited number of information units (chunks) simultaneously. According to Miller, the upper limit is around 7 ± 2 information units.

In neuroweb design, Miller's number can be used to optimise the design and structure of websites. By focussing on the important information units and a clear structure, you can ensure that users can process the information on the website more easily and effectively.

For example, websites with a clear structure and a limited number of navigation points can help users to focus on the most important information and quickly find the information they need. In addition, the use of visual elements such as icons or images can help to divide complex information into smaller chunks and thus facilitate processing.
