What is the Generation Effect?

Have you ever wondered why it is easier to remember something you have created yourself than something you have read or heard from someone else? If so, you are not alone. Many researchers have been interested in this phenomenon, which is known as the Generation effect in learning.

The generation effect refers to the finding that generating information from one’s own memory or knowledge leads to better retention and recall than simply receiving or studying the same information. For example, if you are asked to fill in the blanks in a sentence, you are more likely to remember the words you have generated than the words given to you. But what is the reason behind this effect? How does it influence our learning and memory processes? And how can we use it to improve our learning?

Imagine that you are trying to learn how to tie a knot. You have two options: Watch a video tutorial or try to figure it out yourself. Which option do you think will help you remember the knot better? According to research, the answer is the second one. This is because of the generation effect, which says that information is better remembered if it is actively created from one’s own mind rather than simply read or watched in a passive way.

The generation effect, described in the paper “On interpreting the effects of repetition: Solving a problem versus remembering a solution” (Jacoby, 1978), is one of the best ways to enhance memory and learning. By generating the answer or solution, you are engaging in active learning, which requires more cognitive effort and deeper processing than passive learning. This leads to stronger and more durable memory traces, which will make it easier to retrieve the information later on.

Examples of the Generation effect

The generation effect has been demonstrated in various domains and tasks, such as word recall, problem-solving, concept learning, and text comprehension. Here are some examples of how the generation effect can be applied to different types of learning:

Word recall: In a classic experiment, participants were shown pairs of words, such as “ocean-water” or “bread-_”, and were asked to either read the second word or generate it from the first word. Later, they were tested on their memory of the second word. The results showed that the words that were generated were recalled better than the words that were read.
Problem-solving: In another experiment, participants were given a set of problems, such as “If John is taller than Mary, and Mary is taller than Sue, who is the tallest?” or “John is taller than Mary, and Mary is taller than Sue. Who is the shortest?” They were asked to either solve the problems or read the solutions. Later, they were tested on their memory of the solutions. The results showed that the generated solutions were remembered better than those that were read.
Concept learning: In a third experiment, participants were taught new concepts, such as “A dax is a bird that has a crest and sings” or “A wug is a bird that has no crest and does not sing”. They were asked to either generate examples of daxes and wugs or read examples of daxes and wugs. Later, they were tested on their ability to classify new examples of daxes and wugs. The results showed that the participants who generated examples performed better than the participants who only read examples.
Text comprehension: In a fourth experiment, participants were given a text about the history of chocolate and were asked to either generate questions about the text or read questions about the text. Later, they were tested on their comprehension of the text. The results showed that the participants who generated questions understood the text better than the participants who read the questions.

Key takeaways

If you really want to understand something, don’t read about it. Write about it!

Writing about a topic you want to understand is more effective than reading about it. This is because writing requires you to actively engage with the material, which helps you better understand and remember it. When you write about a topic, you have to organize your thoughts, fill in gaps in your knowledge, and make connections between different pieces of information. This process helps you better understand the topic and commit it to memory. In contrast, reading is a passive activity that doesn’t require you to engage with the material in the same way. While reading can be a great way to learn new information, writing is a more effective way to truly understand and remember it.

The generation effect is a powerful technique to improve your learning and memory. It can help you to form connections between new and pre-existing knowledge, deepen your understanding of the material, and enhance your recall and retention of the information. Here are some key takeaways and tips on how to use the generation effect to aid your learning:

Generate, don’t just read or watch
Whenever possible, try to generate the information you want to learn from your memory rather than simply reading or watching it. For example, if you are reading a book or watching a video, summarize the main points in your own words or explain the concepts to someone else.
Use questions to guide your generation
A good way to generate information is to use questions to prompt your thinking. For example, if you are reading a section of your book, close the book and generate (and answer) questions about what you just read. If there are review questions at the end of a chapter, answer those questions without looking back at the pages. You can also use flashcards to test yourself on the information that you want to learn.
Create your own tests or quizzes
Another way to generate information is to create your own tests or quizzes on the material that you want to learn. For example, if you are preparing for an exam, try to write your own practice questions or problems and then solve them. If you are an educator (or want to write a practice test for a friend), create tests that require fill-in-the-blank, short-answer, or essay responses rather than multiple-choice ones. This will force you to generate the answer rather than just picking it from a list of options.
Prime your mind before learning
The generation effect can also be enhanced by priming your mind before learning new information. Priming is activating your prior knowledge or expectations about a topic, which can help you make connections and associations with the new information. Before reading a text or watching a video, brainstorm what you already know or want to learn about the topic.

The generation effect is a simple but effective way to boost your learning and memory. By generating information from your mind, you are engaging in active and deep learning, which will help you remember and understand the information better. Try applying the generation effect to your learning goals, and see the difference for yourself.
