One way to potentially increase the number of items we can remember by merging them into meaningful units is known as chunking.
A technique connected to cognitive psychology is chunking. The chunking procedure involves breaking down each individual component of a certain collection of information before grouping them into a coherent and meaningful whole. This has a favorable impact on the ability to process information.
Chunking is a memory-enhancing method. A mnemonic technique is a method that a person might employ to enhance their memory. Simply said, it's a shortcut that enables people to associate the information to be remembered with a phrase, word, or other memory aid.
By breaking knowledge up into smaller chunks, chunking is used to help people recall it in the short term. As a result, the human working memory's constrained store capacity is disregarded. A chunk, also known as a piece, is a grouping and storage of fundamental units in long-term memory.
