3 Brain Rules on Attention that You Need to Know

Understanding yourself and how your brain works is crucial for you to make use of it well. Because of that, it is always useful to understand how your brain focus and in what situation will it fail to pay attention. Here, I have summarized three rules on how your brain focus on doing certain things, which would be helpful for you to understand why you can’t pay attention in class.


1. Your Brain Doesn’t Pay Attention to Details

Rule #1: The brain doesn’t pay attention to the details if you don’t know the gist and meaning of the information

Rule: According to Brain Rules, the brain tends to pay more attention to the gist of the information rather than to the peripheral details. If you want to pay attention to the information, you will need to start with an organized core idea and concept before going into the detailed information.

Because of that, we tend to zone out in class when we do not understand the core idea. We find it very difficult to catch up and focus to listen to the details of the information.

Solution: Preview your materials before hand. Get an idea of all the important concepts and big ideas of your topic before going to lecture. This way, you are going to have an understanding of the core concepts. When the teacher goes into the detail, you are less likely to feel lost and more likely to pay attention because you have an organized and hierarchical framework of the information in your mind. This helps you pay attention better in class, and also helps you to learn the information effectively.

For how to prepare for classes so that you can focus better and get the most out of the class, see Why and How Should You Prepare for Lectures?.

2. Your Brain Can’t Multitask

Rule #2: The brain is a sequential processor, and it cannot pay attention to two things at the same time. 

Rule: Once you switch tasks, the brain needs to disengage from your original task before you can act on your second tasks. When you get back to your original task, another switch of attention is required. Because of that, when we multi-task, we need almost double amount of time than people who focus solely on one task. Multitask is said to reduce productivity and increase mistake.

Solution: The solution? Don’t multitask during class. By that I mean not just stop surfing the internet and online shopping, but block off all the distractions. Read the hacks below to find out how you can do so!

3. The 10-Minute Rule

Rule #3: We tend to lose focus and stop paying attention after 10 minutes.

Rule: In the book, the author John Medina has talked about how he realized that, in his lectures, students start to look at the clock when 10 minutes of the lecture time has past. It is said that we normally focus for around 10 minutes in class before we start to have a low attention rate.

The 10-minute rule, as shown in http://www.brainrules.net/attention/?scene=1

Solution: The author has proposed a way to change the structure of the presentation so to retain the audience’s focus. But as students, we of course have no way to change to format of the class. So what can we do?

Medina tells us that having a hook at every 10-minute interval is necessary. The hook has to trigger an emotion and be relevant. While we can’t make your teacher’s presentation interesting, we can, however, take the time to think about the class content and reflect on the information. By thinking about the information, we can generate our own thoughts and ideas on the topic. This gives us questions and ideas in our mind, which triggers emotion and relevancy.

Similarly, by engaging in class and raise questions, you are also triggering your emotion and extending your attention span. This helps you to focus better in class. You are also likely to be more attentive in class in order to look for questions to ask.


So How Can I Stay Focused in Class?

Having gone through the three important brain rules on attention, here is a summarized action points for you to do when you are in class so that you can better pay attention during the long (and boring) lectures and classes.


Hack #1: Do your class preparation and have an understanding of the important concepts

As I said, doing class preparation is the key to overcome the fact that your brain can’t focus on details before grasping the core concepts of the topic. Imagine your brain works like a mind map. It starts with the central core idea, and then it branches out to the details of the topic. If your central core part is missing, the brain can’t construct the mind map by just having the details. Because of that, here is what you have to do.

Steps for Class Preparation

  1. Download the Class Preparation Printable in the ST Resource Library.
  2. Find the outline of the class or topic. This is usually included in your textbook or lecture outline.
  3. After knowing the framework of the class, look into the content and find out the key ideas and information. Jot notes of things that you find important.
  4. Annotate your textbook and materials as you read. Mark and underline important content.
  5. Conduct research if you find a topic intriguing. Doing a background research can enhance your understanding and allow you to have a stronger foundation as you go to your class.
  6. Prepare questions to ask in class and note them down. Also write down things that you do not understand at the moment so that you can better pay attention in class whether the teacher talks about them.


Hack #2: Block off all the distractions and focus only on listening to the lecture

Your brain can’t multitask no matter how hard you try, as mentioned above. Here are some things you can do to remove all the distractions.

Things you can do to remove all the distractions

  • Turn off all your notifications including your email and phone. Don’t let these notifications interrupt your brain.
  • Put your note-taking application on full screen. If possible, turn off the wifi.
  • If turning off your wifi is not possible, try the application SelfControl.
  • You can also take notes using pen and notebook so that you won’t be distracted by your computer.


Hack #3: Engage in class and think actively

Because of the 10-minute rule, it is very difficult for you to just listen to the teacher for the entire time. This is not beneficial to your learning as well, since that means that you are not actively listening and analyzing the information as you sit in the lecture hall. In order to actively learn in lectures, here are what you should do.

Ways to actively learn in class

  • As you listen to your lecturer, take notes effectively.
  • Don’t just blindly copy everything, think about the content and reflect on them.
  • Generate your own ideas and questions as you listen to your teacher.
  • Raise your hands if you have a question so to engage in class.
  • Discuss the class content with your friends during breaks.

  • This would've been so helpful back when I had classes! I used to always get distracted by Facebook and I'd end up having to study all of the lecture notes on my own later haha, definitely not the best idea!
  • These are great tips, I always use to have such a hard time studying now that i am out of school I know what I could have done better.
    • I am glad you found them helpful!
  • super interesting read! I always found the more I forced myself to engage throughout class, the better understanding I had about what was actually going on. x, nicole // www.nicoleeigh.com
    • Participating in class always helps (and it's indeed one of the best ways to learn too)!
  • I took most of my Uni classes online but it's almost HARDER to concentrate when you're in your pajamas during class! These are really good tips though -- I agree going into class as organized as possible helps cut down on distraction!
    • I didn't know that! I would've thought having classes online means that I can learn at my own pace and would make it easier for me to focus. But perhaps the academic environment in the lecture hall has its advantage too!

    I definitely could've used a lot of these when I was in undergrad! It was hard to stay focused in some of my non-major classes sometimes! xoxo A www.southernbelleintraining.com
    • It's indeed difficult to stay focused in lectures, especially if it's not related to something that we are passionate about. I hope these tips help!
