We’ve all experienced moments like these:
- Reminding ourselves to stop at the bakery for breakfast, but forgetting as we walk past.
- Having too many tasks at work, leading to some being left undone by the end of the day.
- Reading something that resonates deeply, but forgetting it by the time we finish the book.
- Having a great idea while walking, only to forget it by the time we get home.
This is where understanding "short-term memory" comes in. It’s a type of memory that keeps a small amount of information active in the brain for a short time. Typically, short-term memory lasts 5 to 20 seconds, but not longer than a minute. "Rehearsal" is a key way to extend its duration, helping us retain information for the next steps.
Scholars believe that when elements like numbers, words, or images enter short-term memory simultaneously, they compete with each other when we try to recall them. New information can replace old information unless the old info is kept active through rehearsal or attention.
In our work and learning, information often comes in fragments. This kind of information may be crucial, like meeting times, task essentials, or report deadlines. While the content isn’t usually complex, it’s easy to forget.
The importance of "real-time note-taking" is clear. It allows us to continuously rehearse information after receiving it, forming a theoretical framework for temporary storage and processing—what we call "working memory."
Here are a few methods to try:
- Carry a pocket notebook and pen to jot down important info and ideas. Handwriting is still seen as more serious and can enhance the importance of the content.
- Use your phone’s note-taking apps. Most people prefer digital tools for to-do lists. Just be careful; digital devices can be distracting when many notifications pop up.
- Use traditional sticky notes. Even though screens dominate the workspace, sticky notes still have their place. Placing important info, like tasks or account details, on the side of your computer is one of the most intuitive and convenient methods.
- Set reminders. After noting down information you need to remember long-term, set an alarm to remind you to rehearse it regularly. This helps you review and organize information in your brain.
Forgetting isn’t necessarily bad, but the effectiveness and prioritization of our memories can greatly impact our life efficiency.
We feel most confident when we know exactly what to do next. Adding new knowledge to our mental library brings satisfaction and joy. In these moments, we realize that we're reducing feelings of chaos, create our own rhythm, and see progress in our lives.
