If the Russian psychologist Ivan Pavlov were alive today, what would he say about smartphones? He might not think of them as phones at all, but instead as remarkable tools for understanding how technology can manipulate our brains.
Pavlov’s own findings — from experiments he did more than a century ago, involving food, buzzers and slobbering dogs — offer key insights into why our phones have become almost an extension of our bodies, modern researchers say. The findings also provide clues to how we can break our dependence.
Pavlov originally set off to study canine digestion. But one day, he noticed something peculiar while feeding his dogs. If he played a sound — like a metronome or buzzer — before mealtimes, eventually the sound started to have a special meaning for the animals.
