The Magic of Memory: How Hermann Ebbinghaus Revealed the Secret of Learning
In the process of learning, how to effectively memorize and recall information has always been an important topic in psychological research. German psychologist Hermann Ebbinghaus was one of the pioneers in this area. He experimentally explored the mechanisms of human memory and specifically discovered the concept of distributed practice. Spreading practice, also known as the spacing effect, refers to dividing a learning task into multiple short practice sessions, conducted over a relatively long period of time. This method is gradually proven to improve the efficiency and persistence of learning.
Humans and other animals learn better when they memorize items from a list when they learn them over several sessions rather than when they learn them repeatedly over a short period of time.
The history and experiments of distributed practice
Ebbinghaus's research focused on nonsense syllables, which allowed him to control external variables such as prior knowledge. He found that dispersed practice retained information more effectively than concentrated practice. In 1978, the famous psychologists Alan Baddeley and Langmen took this topic further when they divided postmen into two groups that received focused practice and those that received dispersed practice. The results showed that while concentrated practice seemed to lead to better progress in less time, those who received dispersed practice performed better in both accuracy and speed.
The psychological mechanism of distributed practice
Several psychological functions are responsible for spreading the benefits of practice. It mainly includes program learning, head-to-tail effect and extended retrieval.
Program learning
Procedural learning refers to practicing a complex task repeatedly until the relevant nervous systems can work together to perform the task automatically. Research has found that distributed practice is the most effective way to learn a program. By spreading the amount of practice evenly over time, the efficiency of learning a skill will be significantly improved.
Head-to-tail effect
The head-to-tail effect means that the first and last memories learned are easier to recall. In distributed learning, when a piece of information is presented multiple times, the learner's first memory of the information is retrieved during the second presentation, further strengthening the memory trace.
Extended search
Extended retrieval refers to testing learning items at different intervals over a period of time. This process relies on consolidated memory to improve the retrieval success rate. Dispersed practice helps with memory consolidation, allowing people to recall information more effectively.
Theories behind different learning tasks
The effects of distributed practice vary across different learning tasks, such as free recall and cued tasks. Whether analyzing semantics or neatly researching, dispersed presentation can trigger different memory processes and provide learners with more retrieval clues.
Practical application and impact
These findings have significant application value in areas such as advertising, personal memory impairment, and long-term memory retention. For example, in the field of advertising, spaced repetition of ads can increase recall, thereby helping brands increase their visibility. And for people affected by traumatic brain injuries, dispersed practice has been shown to help them better master new skills.
Conclusion
With the development of technology and psychology, we understand more and more how human memory works. As an effective learning technique, the principles behind distributed practice are constantly being verified by new research. Can future learning designs make better use of these principles to promote the absorption and retention of knowledge?
