Chunking

Chunking is a cognitive strategy that enhances short-term memory by organizing information into smaller, manageable units, or "chunks."

This method is beneficial for handling large volumes of information, such as numbers, words, or complex ideas.

For example, a 16-digit credit card number is more accessible to recall when divided into groups of four digits.

Research shows that chunking improves memory retention by lowering the cognitive load on working memory, which has a limited capacity.

According to psychologist George A. Miller's "7 plus or minus 2" rule, people can simultaneously hold about five to nine chunks of information in their working memory.

Another example of chunking occurs in language learning.

When memorizing vocabulary words, learners often enhance retention by grouping words into meaningful categories instead of memorizing each word in isolation. This approach helps recall by allowing the brain to associate the words with a specific category.
