Is the Internet changing the way we think?

Over the past few years I’ve had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. My mind isn’t going–so far as I can tell–but it’s changing. I’m not thinking the way I used to think. I can feel it most strongly when I’m reading. Immersing myself in a book or a lengthy article used to be easy. My mind would get caught up in the narrative or the turns of the argument, and I’d spend hours strolling through long stretches of prose. That’s rarely the case anymore. Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I’m always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle.

It’s anecdotal, but I’ve noticed the same thing. I used to read many more books (and magazines, such as The Economist) than I do now. Almost all of my reading occurs on line, and I am much less able to focus than I used to be. But it’s not clear whether this is an effect of aging, or new habits. More the latter, I suspect.
