Does technology rewrite your brain?

While violent video games have gotten a lot of public attention, some current concerns go well beyond that. Some scientists think the wired world may be changing the way we read, learn and interact with each other.

There are no firm answers yet. But Dr. Gary Small, a psychiatrist at UCLA, argues that daily exposure to digital technologies such as the Internet and smart phones can alter how the brain works.

When the brain spends more time on technology-related tasks and less time exposed to other people, it drifts away from fundamental social skills like reading facial expressions during conversation, Small asserts.

So brain circuits involved in face-to-face contact can become weaker, he suggests. That may lead to social awkwardness, an inability to interpret nonverbal messages, isolation and less interest in traditional classroom learning.

Small says the effect is strongest in so-called digital natives — people in their teens and 20s who have been "digitally hard-wired since toddlerhood." He thinks it's important to help the digital natives improve their social skills and older people — digital immigrants — improve their technology skills.
