In 1995 his son was killed by a distracted driver who ran a red light. Meyer’s speciality was attention: how we focus on one thing rather than another. Attention is the golden key to the mystery of human consciousness; it might one day tell us how we make the world in our heads. Attention comes naturally to us; attending to what matters is how we survive and define ourselves. The opposite of attention is distraction, an unnatural condition and one that, as Meyer discovered in 1995, kills. Now he is convinced that chronic, long-term distraction is as dangerous as cigarette smoking. In particular, there is the great myth of multitasking. No human being, he says, can effectively write an e-mail and speak on the telephone. Both activities use language and the language channel in the brain can’t cope. Multitaskers fool themselves by rapidly switching attention and, as a result, their output deteriorates.
Meyer says there is evidence that people in chronically distracted jobs are, in early middle age, appearing with the same symptoms of burn-out as air traffic controllers. They might have stress-related diseases, even irreversible brain damage. But the damage is not caused by overwork, it’s caused by multiple distracted work.
Reading this I started to wonder: Could the demand to deliver differentiated instuction be part of why teachers burn out so quickly? Are teachers who rely more heavily on whole class instruction more productive?
