The document discusses chunking as a strategy to improve memory performance. It explains that chunking involves organizing information into meaningful groups or "chunks" to make it easier to process, remember, and recall. This is because working memory can only hold a limited amount of individual pieces of data at once. The document then provides examples of how to chunk content by listing topics, grouping similar topics, and assigning names to the groups. Chunking reduces the number of individual items one needs to remember and allows information to be recalled more easily through the use of cues and associations between chunks.
