Stop letting your mind run on the auto pilot settings most of society does

Hey You,

It’s #2.

I made a mistake here on the blog the other day that the stud man Tim Birch brought to my attention.   While tinkering with my next post I clicked publish when I meant to click update, saw my mistake, clicked un-publish and then forgot to click update.

So here’s this post sitting half naked in the wind confusing the hell out of everybody.  Good thing it had a marvelous picture attached so people were entertained.  The only reason I’d even posted that part of it was because of all the pictures I was inserting.  On the page where I copy and paste them here from word and from how it shows up on the site is different, so I was trying to get that right when I clicked the wrong button.

And yet some good has come from all this mayhem.

Tim made a comment about a book called “Brain Rules – 12 Rules for Surviving and Thriving at Home, Work, and School”.  Well, just so happens I have notes for it and have decided on behalf of Tim to share them with you in this post.  Thank Tim for any value you get from them…

The author of this book, Dr. John Medina, is a developmental molecular biologist and research consultant. He is an affiliate Professor of Bioengineering at the University of Washington School of Medicine. He is also the director of the Brain Center for Applied Learning Research at Seattle Pacific University.


Rule #1: Exercise boosts brain power.

The human brain evolved under conditions of almost constant motion. From this, one might predict that the optimal environment for processing information would include motion. That is exactly what one finds. Indeed, the best business meeting would have everyone walking at about 1.8 miles per hour.

Researchers studied two elderly populations that had led different lifestyles, one sedentary and one active. Cognitive scores were profoundly influenced. Exercise positively affected executive function, spatial tasks, reaction times and quantitative skills.

So researchers asked: If the sedentary populations become active, will their cognitive scores go up? Yes, it turns out, if the exercise is aerobic. In four months, executive functions vastly improve; longer, and memory scores improve as well.

Exercise improves cognition for two reasons:

  • Exercise increases oxygen flow into the brain, which reduces brain-bound free radicals. One of the most interesting findings of the past few decades is that an increase in oxygen is always accompanied by an uptick in mental sharpness.
  • Exercise acts directly on the molecular machinery of the brain itself. It increases neurons’ creation, survival, and resistance to damage and stress.

Rule #2: The human brain evolved, too.

The brain is a survival organ. It is designed to solve problems related to surviving in an unstable outdoor environment and to do so in nearly constant motion (to keep you alive long enough to pass your genes on). We were not the strongest on the planet but we developed the strongest brains, the key to our survival.

The strongest brains survive, not the strongest bodies. Our ability to solve problems, learn from mistakes, and create alliances with other people helps us survive. We took over the world by learning to cooperate and forming teams with our neighbors.

Our ability to understand each other is our chief survival tool. Relationships helped us survive in the jungle and are critical to surviving at work and school today.

If someone does not feel safe with a teacher or boss, he or she may not perform as well. If a student feels misunderstood because the teacher cannot connect with the way the student learns, the student may become isolated.

There is no greater anti-brain environment than the classroom and cubicle.

You might not be wired for heights like this guy

Rule #3: Every brain is wired differently.

What YOU do and learn in life physically changes what your brain looks like – it literally rewires it. We used to think there were just 7 categories of intelligence. But categories of intelligence may number more than 7 billion—roughly the population of the world.

No two people have the same brain, not even twins. Every student’s brain, every employee’s brain, every customer’s brain is wired differently.

You can either accede to it or ignore it. The current system of education ignores it by having grade structures based on age. Businesses such as Amazon are catching on to mass customization (the Amazon homepage and the products you see are tailored to your recent purchases).

Regions of the brain develop at different rates in different people. The brains of school children are just as unevenly developed as their bodies. Our school system ignores the fact that every brain is wired differently. We wrongly assume every brain is the same.

Most of us have a “Jennifer Aniston” neuron (a neuron lurking in your head that is stimulated only when Jennifer Aniston is in the room).

Rule #4: We don’t pay attention to boring things.

What we pay attention to is profoundly influenced by memory. Our previous experience predicts where we should pay attention. Culture matters too. Whether in school or in business, these differences can greatly affect how an audience perceives a given presentation.

We pay attention to things like emotions, threats and sex. Regardless of who you are, the brain pays a great deal of attention to these questions: Can I eat it? Will it eat me? Can I mate with it? Will it mate with me? Have I seen it before?

The brain is not capable of multi-tasking. We can talk and breathe, but when it comes to higher level tasks, we just can’t do it.

Driving while talking on a cell phone is like driving drunk. The brain is a sequential processor and large fractions of a second are consumed every time the brain switches tasks. This is why cell-phone talkers are a half-second slower to hit the brakes and get in more wrecks.

Workplaces and schools actually encourage this type of multi-tasking. Walk into any office and you’ll see people sending e-mail, answering their phones, Instant Messaging, and on MySpace—all at the same time. Research shows your error rate goes up 50% and it takes you twice as long to do things.

When you’re always online you’re always distracted. So the always online organization is the always unproductive organization.

Rule #5: Repeat to remember.

The human brain can only hold about seven pieces of information for less than 30 seconds! Which means, your brain can only handle a 7-digit phone number. If you want to extend the 30 seconds to a few minutes or even an hour or two, you will need to consistently re-expose yourself to the information. Memories are so volatile that you have to repeat to remember.

Improve your memory by elaborately encoding it during its initial moments. Many of us have trouble remembering names. If at a party you need help remembering Mary, it helps to repeat internally more information about her. “Mary is wearing a blue dress and my favorite color is blue.” It may seem counterintuitive at first but study after study shows it improves your memory.

Brain Rules in the classroom…

In partnership with the University of Washington and Seattle Pacific University, Medina tested this Brain Rule in real classrooms of 3rd graders. They were asked to repeat their multiplication tables in the afternoons. The classrooms in the study did significantly better than the classrooms that did not have the repetition. If brain scientists get together with teachers and do research, we may be able to eliminate need for homework since learning would take place at school, instead of the home.

Rule #6: Remember to repeat.

It takes years to consolidate a memory. Not minutes, hours, or days but years. What you learn in first grade is not completely formed until your sophomore year in high school.

Medina’s dream school is one that repeats what was learned, not at home, but during the school day, 90-120 minutes after the initial learning occurred. Our schools are currently designed so that most real learning has to occur at home.

How do you remember better? Repeated exposure to information / in specifically timed intervals / provides the most powerful way to fix memory into the brain.

Forgetting allows us to prioritize events. But if you want to remember, remember to repeat.

Doesn't matter what you do for a living - you need a nap!

Rule #7: Sleep well, think well.

When we’re asleep, the brain is not resting at all. It is almost unbelievably active! It’s possible that the reason we need to sleep is so that we can learn.

Sleep must be important because we spend 1/3 of our lives doing it! Loss of sleep hurts attention, executive function, working memory, mood, quantitative skills, logical reasoning, and even motor dexterity.

We still don’t know how much we need! It changes with age, gender, pregnancy, puberty, and so much more.

Napping is normal. Ever feel tired in the afternoon? That’s because your brain really wants to take a nap. There’s a battle raging in your head between two armies. Each army is made of legions of brain cells and bio-chemicals – one desperately trying to keep you awake, the other desperately trying to force you to sleep. Around 3 p.m., 12 hours after the midpoint of your sleep, all your brain wants to do is nap.

Taking a nap might make you more productive. In one study, a 26-minute nap improved NASA pilots’ performance by 34 percent.

Don’t schedule important meetings at 3 p.m. It just doesn’t make sense.

Rule #8: Stressed brains don’t learn the same way.

You brain is built to deal with stress that lasts about 30 seconds. The brain is not designed for long term stress when you feel like you have no control. The saber-toothed tiger ate you or you ran away but it was all over in less than a minute.

If you have a bad boss, the saber-toothed tiger can be at your door for years, and you begin to deregulate. If you are in a bad marriage, the saber-toothed tiger can be in your bed for years, and the same thing occurs. You can actually watch the brain shrink.

Stress damages virtually every kind of cognition that exists. It damages memory and executive function. It can hurt your motor skills. When you are stressed out over a long period of time it disrupts your immune response. You get sicker more often. It disrupts your ability to sleep. You get depressed.

The emotional stability of the home is the single greatest predictor of academic success. If you want your kid to get into Harvard, go home and love your spouse.

You have one brain. The same brain you have at home is the same brain you have at work or school. The stress you are experiencing at home will affect your performance at work, and vice versa.

Rule #9: Stimulate more of the senses.

Our senses work together so it is important to stimulate them! Your head crackles with the perceptions of the whole world, sight, sound, taste, smell, touch, energetic as a frat party.

Smell is unusually effective at evoking memory. If you’re tested on the details of a movie while the smell of popcorn is wafted into the air, you’ll remember 10-50% more.

Smell is really important to business. When you walk into Starbucks, the first thing you smell is coffee. They have done a number of things over the years to make sure that’s the case.

The learning link. Those in multisensory environments always do better than those in uni-sensory environments. They have more recall with better resolution that lasts longer, evident even 20 years later.

Rule #10: Vision trumps all other senses.

We are incredible at remembering pictures. Hear a piece of information, and three days later you’ll remember 10% of it. Add a picture and you’ll remember 65%.

Pictures beat text as well, in part because reading is so inefficient for us. Our brain sees words as lots of tiny pictures, and we have to identify certain features in the letters to be able to read them. That takes time.

Why is vision such a big deal to us? Perhaps because it’s how we’ve always apprehended major threats, food supplies and reproductive opportunity.

Toss your PowerPoint presentations. It’s text-based (nearly 40 words per slide), with six hierarchical levels of chapters and subheads—all words. Professionals everywhere need to know about the incredible inefficiency of text-based information and the incredible effects of images. Burn your current PowerPoint presentations and make new ones.

Rule #11: Male and female brains are different.

What’s different? Mental health professionals have known for years about sex-based differences in the type and severity of psychiatric disorders. Males are more severely afflicted by schizophrenia than females.

By more than 2 to 1, women are more likely to get depressed than men, a figure that shows up just after puberty and remains stable for the next 50 years. Males exhibit more antisocial behavior. Females have more anxiety. Most alcoholics and drug addicts are male. Most anorexics are female.

Men and women handle acute stress differently. When researcher Larry Cahill showed them slasher films, men fired up the amygdale in their brain’s right hemisphere, which is responsible for the gist of an event. Their left was comparatively silent. Women lit up their left amygdale, the one responsible for details. Having a team that simultaneously understood the gist and details of a given stressful situation helped us conquer the world.

Men and women process certain emotions differently. Emotions are useful. They make the brain pay attention. These differences are a product of complex interactions between nature and nurture.

Rule #12: We are powerful and natural explorers.

The desire to explore never leaves us despite the classrooms and cubicles we are stuffed into. Babies are the model of how we learn—not by passive reaction to the environment but by active testing through observation, hypothesis, experiment, and conclusion. Babies methodically do experiments on objects, for example, to see what they will do.

Google takes to heart the power of exploration. For 20 percent of their time, employees may go where their mind asks them to go. The proof is in the bottom line: fully 50 percent of new products, including Gmail and Google News, came from “20 percent time.”

I know some of these notes are brief but I imagine you get the gist of what the rule meant.  If you want even more details make sure to go find the book, “Brain Rules – 12 Principles for surviving and Thriving at Work, Home, and School.

Once again thanks Tim for inspiring this post.
