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.

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.

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.

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.

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.

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.

You don't have a work brain and a home brain. You have a single brain, one you carry with you wherever you go. Whatever affects you in one place is fully capable of affecting you at the other.
