The Spacing Effect: How to Improve Learning and Maximize Retention - Farnam Street

"Stay in the Game"

We are not taught how to learn in school, we are taught how to pass tests. This approach to education often leaves us ill-equipped to truly retain and apply the knowledge we acquire. However, learning how to learn is a crucial skill that can greatly benefit us in all areas of life. As Gerald Edelman once said, "Every perception is to some degree an act of creation, and every act of memory is to some degree an act of imagination."

In order to thrive in a constantly changing environment, we must adopt a "work smarter, not harder" approach. This means moving away from rote memorization, which can be tedious and ineffective. Instead, we should focus on the spacing effect. Hermann Ebbinghaus, a German psychologist, first identified this phenomenon, which suggests that we are better able to recall information and concepts if we learn them in multiple, spread-out sessions.

To maximize retention, it is important to incorporate frequent repetitions. Under normal conditions, frequent repetitions aid memory. Additionally, the intensity of emotion and attention plays a significant role in our ability to retain information. The more interested and emotionally engaged we are in a subject, the more likely we are to remember it.

Interestingly, even when we think we have forgotten information, it is likely stored in our subconscious minds. Our brains have a remarkable ability to remember and retrieve information, particularly when it has been encoded through repeated retrieval. This is why the second time we learn something requires noticeably less time or repetitions than the first. Our subconscious minds play a crucial role in this process, allowing us to effortlessly recall important information.

Contrary to popular belief, memorization is not the key to learning. Our brains are not designed to simply memorize information. Instead, they are built to think and automatically hold onto what is important. As Gabriel Wyner puts it in his book "Fluent Forever: How to Learn Any Language and Never Forget It," "There is no such thing as memorizing. We can think, we can repeat, we can recall and we can imagine, but we aren't built to memorize."

Memories are not located in any one part of the brain. Rather, they are formed through a complex process that involves the entire brain. Different parts of our brain encode various aspects of a memory, such as the look of a book, the storyline, the emotions it evokes, and even the smell of the pages. These disparate components come together to create a holistic memory.

Retrieving memories is a crucial part of the learning process. When we struggle to remember something, the act of retrieval actually changes the way the memory is later encoded. The more effort we put into recalling information, the better we will be able to recall it in the future. This is why recall is more important than recognition.

Our brains assign greater importance to repeated information, and semantic priming further enhances our ability to recall words and concepts. Spaced repetition, while requiring forward planning and a small investment of time to set up a system, is a highly effective method for retaining information. It allows us to reinforce previously learned material by retrieving it from memory, making us more interested and receptive to learning.

To implement spaced repetition effectively, it is essential to break up with cramming and focus on what actually works. This requires a system that tracks progress and provides a sense of progression and improvement. By consistently engaging in spaced repetition, we can enhance our learning and maximize retention.

In conclusion, learning how to learn is a valuable skill that can greatly benefit us in all areas of life. By understanding the spacing effect and incorporating spaced repetition into our learning routine, we can improve our ability to retain and recall information. Here are three actionable pieces of advice to help you implement these strategies:

1. Create a system: Set up a system for spaced repetition that works for you. This could be using flashcards, scheduling regular review sessions, or utilizing online tools or apps specifically designed for spaced repetition.

2. Find your passion: Engage with subjects and topics that genuinely interest you. The more emotionally invested you are in a subject, the more likely you are to retain and recall information related to it.

3. Track your progress: Keep a record of your learning journey and regularly review your progress. This will not only give you a sense of accomplishment but also help you identify areas that need further attention.

Remember, learning is a lifelong journey, and by incorporating effective learning strategies such as spaced repetition, you can stay in the game and continuously improve your knowledge and skills.
