Your Phone vs. Your Heart
By BARBARA L. FREDRICKSON March 23, 2013
CAN you remember the last time you were in a public space in America and didn't notice that half the people around you were bent over a digital screen, thumbing a connection to somewhere else?
Most of us are well aware of the convenience that instant electronic access provides. Less has been said about the costs. Research that my colleagues and I have just completed, to be published in a forthcoming issue of Psychological Science, suggests that one measurable toll may be on our biological capacity to connect with other people.
Our ingrained habits change us. Neurons that fire together, wire together, neuroscientists like to say, reflecting the increasing evidence that experiences leave imprints on our neural pathways, a phenomenon called neuroplasticity. Any habit molds the very structure of your brain in ways that strengthen your proclivity for that habit.
Plasticity, the propensity to be shaped by experience, isn't limited to the brain. You already know that when you lead a sedentary life, your muscles atrophy to diminish your physical strength. What you may not know is that your habits of social connection also leave their own physical imprint on you.
How much time do you typically spend with others? And when you do, how connected and attuned to them do you feel? Your answers to these simple questions may well reveal your biological capacity to connect.
