Use the 'Chunking' Method to Actually Remember What You Studied

Studying is a necessary pain when one is in school, which is why we have devised so many ways to do it. Everyone learns differently, but some methods are more trusted than others. "Chunking," for instance, is a real-deal psychological trick that the biggest brains in psychology swear by. Here's how to do it if you have a big cram session coming up.

What is chunking?

Here's what the American Psychological Association says: Chunking is "the process by which the mind divides large pieces of information into smaller units (chunks) that are easier to retain in short-term memory. As a result of this recoding, one item in memory (e.g., a keyword or key idea) can stand for multiple other items (e.g., a short list of associated points)."

Basically, your short-term memory has a specific capacity for how many units it can store and that capacity is pretty low, ranging from five to nine--but the units themselves can be as complex as you want. The APA says "the exact number of chunks remembered depends on the size of each chunk or the subunits contained within each chunk."

Each chunk is a collection of pieces of related information, like words, numbers, or phrases. The key here is they have to be related to each other, but not very related to the other chunks. Chunking is all about grouping related pieces of information so you can stay in that five-to-nine units frame.

You probably already use chunking in your real life to remember things. Think of your phone number. You likely already sort it into your area code, those first three digits, and the final four digits. Remembering a string of 10 numbers is hard; remembering three "chunks" of smaller digits is less difficult.

So how do you study in chunks?

Look at the things you have to memorize and start grouping them loosely into categories based on how they're related. This doesn't have to be about content, either. If you have to memorize 20 words or concepts, you don't have to group them by their meaning; you can group them by whether they sound similar, start with the same letter, or whatever you want.

On a new piece of paper, create your chunks, listing the words or concepts together and skipping a few spaces between units. From here, you can make flashcard sets of each chunk or use the first letter of each phrase to create a mnemonic device. Try an acrostic, a phrase where the first letter of each word corresponds with the first letter of one of the things you need to remember. If you think better in terms of numbers, try grouping your words or concepts by how many letters are in them.

Study each set--or chunk--individually. Even though this doesn't break down the amount of content, having them in groups with similar characteristics will help you remember it all together, and you'll be surprised how much of the real material you retain.
