When you start a new chapter, go on a “picture walk” through it. Scan it. Look briefly at all the pictures, captions, and diagrams, but also at the section headings, bold words, and summary, and even questions at the end of the chapter, if the book has them.
The diffuse mode helps you make imaginative connections between ideas. Creativity often seems to pop out of using the diffuse mode. It turns out that your brain has to go back and forth between focused and diffuse modes in order to learn effectively.
But it seems that the best ways to give your diffuse mode a chance to work out a difficult problem are through activities like sleeping, exercising, or going for a ride in a vehicle.
If there’s something you tend to get stuck at, start with this subject when you are studying. That way you can go back and forth to your other class work over the course of the afternoon and evening when you might find yourself getting stuck. You don’t want to leave your hardest subject to the end when you are tired and have no time for diffuse learning.
General Diffuse Mode Activators
Play a sport like soccer or basketball
Jog, walk, or swim
Dance Enjoy being a passenger in a car or bus Ride a bike
Draw or paint
Take a bath or shower
Listen to music, especially without words
Play songs you know well on a musical instrument
Meditate or pray
Sleep (the ultimate diffuse mode!)
To your brain, thinking about cleaning your room feels like the start of a stomachache. But here’s what’s interesting. Once you get started on the task you didn’t want to do, the pain goes away after about twenty minutes. The insular cortex calms down when you start the task you were avoiding. It’s happy that you’re finally getting on with the job.
When you’re looking forward to a reward, your brain helps you focus better.
I’ll admit that if I want to keep working after the time is up, I go ahead. Getting into the flow, where I’m really into doing the task, is a good thing. But when I stop, I always reward myself. It’s diffuse mode time! If I’ve been writing (like this book), I listen to a favorite song. Or I get up and make a cup of tea and look out the window. I don’t write during my break. That way, the “writing” part of my brain gets a rest.
It’s a good idea to do something during your break that’s very different from what you have been focusing on.
If you’ve been sitting while you study, breaks where you move your body around are often the best.
But the idea of multitasking is a mistake. Your focus can only be on one thing at a time. When you switch your attention, you waste mental energy, and you will perform worse. It’s like a pinball machine where two balls have been released instead of one, and you have to crazily try to manage both the balls. You inevitably fail and both balls drop.
Look away from the page and see what you can recall. What are the key ideas on the page? Play them back in your mind.
Coming up with a creative metaphor is one of the best ways to learn a new concept or share an important idea.
Leave your work to the last minute, and you have less time to repeat and fewer nights of sleep to grow new synapses—so you won’t recall the details well.
Brief practice sessions over a number of days are better for storing information in memory than one long practice session.
Imagine a place that you know well, like your house. Then take the things you need to remember and mentally “put” them in places throughout your house as you walk through it. Make sure something is shocking or silly about the way you imagine each of them. Add a little movement to them. Then picture yourself walking through the house and seeing them. Maybe even talking to them.
But just understanding a concept does not create a set of brain-links. You must practice a new concept to create the set of brain-links.
Vegetables from the onion family, which includes garlic and leeks, contain chemicals that help keep away all sorts of diseases, from diabetes to cancer. So do vegetables from the cabbage family, which includes cauliflower, broccoli, radishes, and Brussels sprouts.
Exercise does something else magical. It enables your brain to produce other chemicals, such as serotonin and dopamine.5 These chemicals help you come up with new ideas. They allow you to see how old ideas can link up to form new ones. Then you can think in new ways.
The key is to actively practice or bring to life whatever you are learning yourself. Just watching other people, or looking at a solution, or reading a page, can allow you to get started. But it won’t do much to build your own neural structures of learning.
Watching other people, looking at a solution, or reading a page can help you get started. But it won’t do much to build your own neural structures of learning. Only actively working with the materials will help you build strong brain-links.
You create and strengthen sets of brain-links through deliberate practice. That’s focused, repeated work on the more difficult parts of a concept. Don’t waste much time on the easy stuff that you already know.
It may seem strange at first, but it’s good to change the place where you study.
Move your chair sometimes to a different part of the room. Take notes with a different color pen. Move your lamp.
So whenever you’re learning anything, try to take advantage of all your senses. Don’t think of yourself as having a preferred learning style. Think of yourself as an “all-inclusive” learner. If you imagine hearing a famous person from history speaking to you, or you visualize a chemical, that counts as multisensory learning, which is the most effective kind. For everyone.
It’s best to get started on the unpleasant or difficult things first in your study session. That way, you can take a break and work on something else if you get stuck.
When you can, set a firm daily quitting time to allow you to concentrate more intently when you are working.
Action video games are great for focusing. While you’re having fun, you’re also learning to concentrate. When you play an action video game, your mental mouse runs up and down a centrally important brain path. It’s the “focus” path in your brain, and it gets wider as you use it more. Becoming a strong video gamer means that when you turn your attention to something, you can really focus.
Games like Tetris can build your spatial (“SPAY-shell”) abilities. That means you can learn to rotate things more easily in your mind’s eye. This is an important skill in math and science.
If you decide to get great at something, you tend to want to spend all your time doing it. But the fact is, everybody else who is trying to get great at it is doing the same thing. So how can you do better than they are if you’re doing exactly what they’re doing?
Ready to be surprised again? The way to get better is to strike out in a completely different direction. You learn about something else. Anything else. Whatever you learn, your brain finds a way to make those ideas useful for your main passion, often through metaphor.
Writing notes by hand is better. Even if you have lousy handwriting.* Remember, you need to make a set of brain-links out of the key ideas. Amazingly, if you just type what you are hearing, the words flow onto the page without creating a set of links. Into the ears, out of the hands, with no deep brain work in between.
A good approach to note taking is to draw a line down one side of the page, about one-third of the way from the edge. Write your first notes in the larger section. Then later, when you review them, write even briefer key points in the smaller section. Then look away and see if you can recall those key points.
When you begin your test, here’s what you should do. Start by quickly looking it over. Make a little checkmark beside what you think are the hardest problems. Then pick one of the hard problems and start working on it. Yes, that’s right—a hard problem. (Eat your frogs first!)
Just work on this problem a minute or two—however long it takes until you feel like you’re stuck.
As soon as you feel yourself getting stuck, leave it. Look for an easier problem to boost your confidence. Do that next. And then maybe another one.
Then go back to the hard problem. You may now be able to make some progress.
Just highlighting or underlining big chunks of text doesn’t put anything in your head. Make brief notes about the key concepts you are reading.
Use deliberate practice—focus on what you find most difficult.
To be more creative and get better at something you are passionate about, you should spend a little time doing something very different. This helps keep you mentally flexible and more creative.
