Best 62 quotes of John Medina on MyQuotes

Americans have been good at improvising for a long time, but in the last few decades, we have gotten very sloppy about the rote memorization of facts. That's a discipline issue. You need the rote skill in order to have something to improvise off of, otherwise you are simply playing air guitar.

Any education system that only memorizes things creates robots and will never produce Nobel laureates. Any education system that only emphasizes improvisation will get a bunch of people who may think they are creative, but they are functionally illiterate.

A third or more of the brain is devoted to visual processing, not true of any other sense. We have color vision and it is truly binocular. This sophistication is not true of other senses, such as smell, where many genes are actually mutated and no longer work.

Babies learn through a series of increasingly self-corrected ideas. They use very sophisticated hypothesis testing strategies to find out about their world.

Based on research into the Picture Superiority Effect, when we read text alone, we are likely to remember only 10 percent of the information 3 days later. If that information is presented to us as text combined with a relevant image, we are likely to remember 65 percent of the information 3 days later.

Brain scientists and education scientists don't get together very often, and we end up living in our own little silos.

Don't start with the details. Start with the key ideas, and in a hierarchical fashion, form the details around these larger notions.

Empathy works so well because it does not require a solution. It requires only understanding.

Even though we don't know squat about how the brain works, the little we do know suggests that if you wanted to design a learning environment that was directly opposed to what the brain was naturally good at doing, you would design the education system we currently have, not only in America, but all over the world!

Every brain is wired differently from every other brain, and learns in ways unique to that wiring.

Having a first child is like swallowing an intoxicating drink made of equal parts joy and terror, chased with a bucketful of transitions nobody ever tells you about.

Here's why this matters: Studies show that a person who is interrupted takes 50 percent longer to accomplish a task. Not only that, he or she makes up to 50 percent more errors.

Historically, very few discoveries were made out of thin air. Most of the greatest insights depended upon the intellectual ecology in which the scientists lived. A certain critical mass of "new findings" occurred, and bright people all over the world found out about it, and several read the tea leaves the same way.

Human learning is a very aggressive style in its native state. I am not sure why, though it is a very useful trait in an unstable, unpredictable living environment.

If managers knew how deeply their behaviors could affect brain function - whether they are piling up too much work on someone or yelling at them for "motivational purposes", they would quit doing it.

If you are curious, you won't be satisfied with the "tyranny of custom." People stuck in that rut might say "why?" and the first thing an exploratory person would say is "why not?

If you wanted to create an education environment that was directly opposed to what the brain was good at doing, you probably would design something like a classroom. If you wanted to create a business environment that was directly opposed to what the brain was good at doing, you probably would design something like a cubicle. And if you wanted to change things, you might have to tear down both and start over.

If you wanted to create an education environment that was directly opposed to what the brain was good at doing, you would probably design something like a classroom.

I have great confidence in human curiosity - even though I don't know what curiosity is from a biological point of view. One of its characteristics has got to be the willingness to explore.

I think the most incredible fact about the brain is that it is the only piece of biological real estate that can actually study itself. I can think about that for decades - I have, actually - and still be in drop dead amazement.

Most brain scientists have not taught 4th grade, and don't know very much about the classroom, even though they might study learning in some detail. Most education professionals, who often know a tremendous amount about the classroom, don't know much about the brain. That is one of the reasons why I am so skeptical about applying brain findings to the classroom.

Not even identical twins can have the exact same experiences, and their brains are not wired the same way.

One of the greatest predictors of academic success that exist is the emotional stability of the home. So if parents are interested in education reform, they should also be interested in how they conduct themselves in front of their children. If they are homeschooling their kids, they are even more exposed, so the idea is even more important.

Our ability to adapt came from our East African birthplace, a meteorologically unstable place. If you couldn't adapt, you'd be dead. But once you've found a solution, there is no need to continue the adaptive behavioral parrying, which is bioenergetically very expensive to maintain. We are built to find answers, then hang on to them as long as we can.

People try to apply directly results from the cognitive neurosciences directly to classroom practice and I have to tell you I am very skeptical about the exercise. We don't know very much about how the brain works - we don't even know how you remember to write your name.

Public speaking professionals say that you win or lose the battle to hold your audience in the first 30 seconds of a given presentation.

The ability to double our biomass - not by waiting several million years and growing to be the size of an elephant - but waiting a few hundred thousand years for neurons to sprout into our brains - ones capable of having us create emotional relationships with other members of our species. We thereby double our biomass not by getting bigger, but by creating an ally.

The brain appears to have been designed to solve problems related to surviving in an outdoor setting, in unstable meteorological conditions, and to do so in near constant motion.

The brain cannot multitask. Multitasking, when it comes to paying attention, is a myth. The brain naturally focuses on concepts sequentially, one at a time…To put it bluntly, research shows that we can’t multitask. We are biologically incapable of processing information-rich inputs simultaneously…Studies show that a person who is interrupted takes 50 percent longer to accomplish a task. Not only that, he or she makes up to 50 percent more errors.

The brain doesn't care about change. As the world's most sophisticated survival organ, the brain cares about loss.

The brain doesn't pay attention to boring things.

The brain processes meaning before detail. Providing the gist, the core concept, first was like giving a thirsty person a tall glass of water. And the brain likes hierarchy. Starting with general concepts naturally leads to explaining information in a hierarchical fashion. You have to do the general idea first. And then you will see that 40 percent improvement in understanding.

The brain remembers the emotional component of an experience better than any other aspect.

The distance between a gene and a behavior is of greatest interest to me. The relative contributions of nature and nurture, of nucleotide and nuclear family, are perpetually fascinating to me.

The problem in today’s economy is that people are typically starting a family at the very time they are also supposed to be doing their best work. They are trying to be productive at some of the most stressful times of their lives. What if companies took this unhappy collision of life events seriously? They could offer Gottman’s intervention as a benefit for every newly married, or newly pregnant, employee.

There are estimates that we daily walked for 10 - 20 kilometers for hundreds of thousands of years. The world's best problem solving machinery grew up under conditions of consistent, strenuous physical activity. It makes sense that when we don't recreate the environments in which the organ was forged, we get a loss of function. And that when we do restore those environments, we get that function back. The effects of aerobic exercise on executive function skills is a powerful empirical example of this idea.

There are nature and nurture components to virtually every behavior a human experiences. The research effort lies only in finding the relevant percentages, not on some absolute value. That's one of the reasons behavioral scientists have to be really good statisticians.

There is a neuron in your brain that will respond only to pictures of Jennifer Aniston - provided you have had prior visual exposure to the actress. That neuron does not respond to pictures of Bill Clinton or Halle Berry. Only Jennifer. I used the story to explain the almost ridiculous plasticity of the organ. There is no such thing as Jennifer Aniston in our evolutionary history - she was born in 1969, for heaven's sake - but we are flexible enough to devote an entire cell to her if we have previously encountered her in some fashion.

Though we have been stuffing them into classrooms and cubicles for decades, our brains actually were built to survive in jungles and grasslands. A lifetime of exercise can result in a sometimes astonishing elevation in cognitive performance, compared with those who are sedentary.

To improve short-term memory significantly, reduce the stress in your life. And choose your parents wisely.

To put it bluntly, research shows that we can’t multitask. We are biologically incapable of processing attention-rich inputs simultaneously.

We must do a better job of encouraging lifelong curiosity.

What you do and learn in life physically changes what your brain looks like—it literally rewires it.

Whether at work, home or school, everybody carries their brain around them, and if the organ suffers from a disorder, we carry the disorder around with us too.

Women tend to recall the details of an emotionally competent stimulus, using more of their left hemisphere to do the processing. Men tend to recall the gist aspects of an emotionally competent stimulus, using more of their right hemisphere to do the processing.

Years of research show us that the less control a person feels over an aversive stimuli coming at them, the more likely they are to disengage. Complete loss of control over a sustained period of time can actually lead to depression. It then follows that giving the person a level of control over the situation reduce the stress - and perhaps restore the disengagement.

You've got seconds to grab your audience's attention and only minutes to keep it.

Are you a lark, an owl or a hummingbird? Lark, also called early chronotype, is someone who does usually wake up very early. They are most active during morning around 6:00 am. Approximately 10% of people are larks. Owl, also called late chronotype, is someome who does usually wake up very late. They are most active in the evening around 6:00 pm. They usually drink a lot of coffee and accumulate a massive sleep debt as they go through life. Approximately 10% of people are owls. The rest, around 80% of people, are hummingbirds. Some hummingbirds are more larkish, some more owlish and some are in between.

At birth, your baby can distinguish between the sounds of every language that has ever been invented. Professor Patricia Kuhl, co-director of the Institute for Learning and Brain Sciences at the University of Washington, discovered this phenomenon. She calls kids at this age “citizens of the world”. Chomsky puts it this way: We are not born with the capacity to speak a specific language. We are born with the capacity to speak any language. Unfortunately, things don’t stay that way. By their first birthday, Kuhl found, babies can no longer distinguish between the sounds of every language on the planet. They can distinguish only between those to which they have been exposed in the past six months. A Japanese baby not exposed to “rake” and “lake” during her second six months of life cannot distinguish between those two sounds by the time she is 1 year old.

Emotions get our attention.
