As a researcher investigating how electric brain stimulation can improve people's powers of recollection, I'm often asked how memory works – and what we can do to use it more effectively.
which can last only milliseconds, registers raw information such as sights, sounds and smells. These are first processed by the brain's fiveholds and manipulates a small amount of information over several seconds or more. Think of this as your brain's mental workspace: the system that lets you do mental arithmetic, follow instructions and comprehend what you're reading. So it mainly involves thestores information more permanently, from minutes to a lifetime. This includes both'explicit' memories and'implicit' ones .
– located deep within the brain, around the sides of your head near your temples – contribute largely to memories involving facts or life events, while theBut you can also get your memory working more effectively. Here are five easy steps for improving both your working and long-term memory.
The reason is that part of your brain is still subtly monitoring it. Even resisting the urge to check notifications consumes mental resources – which is whya'brain drain'. The solution is simple: put your phone in another room when you need to focus. Out of sight really does free up mental capacity.
When you're worrying about something or are distracted by racing thoughts, part of your working memory is already in use.can improve both working memory and academic performance, probably by reducing stress levels. And if meditation feels intimidating, try breathing techniques such as. Inhale deeply through your nose, take a second shorter inhale, then slowly exhale through your mouth. Repeating this for five minutes can calm the nervous system and create better conditions for learning.
– grouping information into meaningful units. In fact, you probably already do it to remember some phone numbers or lists of words – breaking long sequences into bite-size chunks that your brain can recall as a mini-group. The same principles apply if you're delivering a presentation, to help your audience remember your key points more effectively. Chunking would involve grouping ten case studies, say, into three or four themes, each with a short headline and single key takeaway. Repeat this structure on each slide: one idea, a few supporting details, then move on. By organising information into meaningful patterns, you reduce cognitive load and make it more memorable.
In the 19th century, German psychologist Hermann Ebbinghaus demonstrated how quickly we forget information after learning it. Within about 30 minutes, we lose roughly half of what we have learned, with much more fading over the next day. Ebbinghaus called thisHowever, there is a way of ensuring that more sinks in when you are trying to learn a lot of information in a short period of time: When preparing to give a talk or studying for an exam, rather than simply rereading your notes, keep testing how much you remember. Use flash cards, answer practice questions, or try explaining the material out loud without notes. Memory works through associations. Each time you successfully retrieve information, you link the material to new prompts, examples and contexts. This, rather than massed together.
If you are studying for an exam, build solid blocks of downtime into your revision schedule. The dark blue line on the chart above illustrates how spacing out your practice sessions can help you remember more information over time, by adjusting Ebbinghaus's forgetting curve.until your exam or presentation. So, if your deadline is five days away and you do hours of revision a day, you should still take between a half and full day off in between sessions. In other words, don't overdo it – you probably won't see the rewards!
If you only remember one thing from this article about improving memory, make it this. Memory isn't just about intelligence, it's about strategy. Small changes in how you study or work can make a real difference in how well, and how long, you remember crucial information.
