Frequent social network use releases dopamine in response to online interactions, setting up a potentially addictive cycle, according to Steve Daviss of the Baltimore Washington Medical Center to USA Today.”There’s good evidence the feedback we get from technology — the retweets and bings and pings that come out of the phone every time somebody sends us a text message — create a reward system in the brain that gives us a little squirt of dopamine each time,” Daviss says. “For some people, that can turn into what looks a lot like addiction. Some people have a harder time regulating their behavior in response to this reward. The ones who really can’t turn it off in their brain are the ones who start to get in trouble.”
