We need to blinker ourselves, to better monitor our attentional focus. Enforced periods of no email or Internet to allow us to sustain concentration have been shown to be tremendously helpful. And breaks - even a 15-minute break every two or three hours - make us more productive in the long run.
If you're making a bunch of little decisions - like, do I read this email now or later? Do I file it? Do I forward it? Do I have to get more information? Do I put it in the spam folder? - that's a handful of decisions right there, and you haven't done anything meaningful. It puts us into a brain state of decision fatigue.
We get stressed out now by having somebody yell at us in the office or by making a mistake or by losing a bunch of money. These aren't problems that our hunter-gatherer ancestors had. They'd get stressed if a lion came to them or a boulder was rolling towards their living quarters. That kind of stress provoked the fight or flight response.
There are people from lots of different fields in my department. In my lab, they come from computer science, education, psychophysics, psychology, music - and we all work together, and it feels very comfortable. All the careers I've had have been interdisciplinary; working in a studio is like being an engineer and a musician and a therapist.
Across a range of inferences involving not just language but mathematics, logic problems, and spatial reasoning, sleep has been shown to enhance the formation and understanding of abstract relations, so much so that people often wake having solved a problem that was unsolvable the night before.
We're a social species, and we want to get along with the people we like and who are like us. That's just good adaptive behaviour. We're more likely to accept something if we hear it from a friend, whereas we're sceptical of people who are not like us - which is what leads to racism, nationalism, sexism and all forms of bigotry.
Every status update you read on Facebook, every tweet or text message you get from a friend, is competing for resources in your brain with important things like whether to put your savings in stocks or bonds, where you left your passport, or how best to reconcile with a close friend you just had an argument with.
The history of science and culture is filled with stories of how many of the greatest scientific and artistic discoveries occurred while the creator was not thinking about what he was working on, not consciously anyway - the daydreaming mode solved the problem for him, and the answer appeared suddenly as a stroke of insight.
Our ancient forebears who learned to synchronize the movements of dance were those with the capacity to predict what others around them were going to do and signal to others what they wanted to do next. These forms of communication may well have helped lead to the formation of larger human communities.
