James E. Katz, director of the Center for Mobile Computing at Rutgers University, said the data coming from the devices was really secondary. “Look at a lot of the communication — it’s idiotic in terms of substance,” Mr. Katz said. “But it’s vital in terms of meaning.”

Mr. Katz argues that participation gives people a sense of belonging, one traceable to the atavistic desire to congregate and cooperate for safety and survival. In addition, he said, the constant checking is an exercise in optimism, like being an explorer or a gambler. Eternal hope delivered in tiny bits while you’re on the go.

“It’s random reinforcement,” Mr. Katz said. The fact that you don’t know when important news will come, he said, “means you will quickly engage in obsessive compulsive behavior.”

These social needs and yearnings may drive the use. But at some point, that use becomes an end unto itself — a physical ritual that can take on some of the qualities of actual addiction, said Dr. John Ratey, a clinical associate professor of psychiatry at Harvard, where he specializes in neuropsychiatry.

Several years ago, Mr. Ratey began using the term “acquired attention deficit disorder” to describe the condition of people who are accustomed to a constant stream of digital stimulation and feel bored in the absence of it. Regardless of whether the stimulation is from the Internet, TV or a cellphone, the brain, he said, is hijacked.
