experiences tied to too much time on the Web.

"There's no question that there're people who're seriously in trouble because they're overdoing their Internet involvement," said psychiatrist (精神科医生) Ivan Goldberg. Goldberg calls the problem a disorder rather than a true addiction.

Jonathan Bishop, a researcher in Wales specializing in online communities, is more skeptical. "The Internet is an environment," he said. "You can't be addicted to the environment." Bishop describes the problem as simply a matter of priorities, which can be solved by encouraging people to prioritize other life goals and plans in place of time spent online. The new CNS Spectrums study was based on results of a nationwide telephone survey of more than 2,500 adults. Like the 2005 survey, this one was conducted by Stanford University researchers. About 6% of respondents reported that "their relationships suffered because of excessive Internet use." About 9% attempted to conceal "nonessential Internet use," and nearly 4% reported feeling "preoccupied by the Internet when offline."

About 8% said they used the Internet as a way to escape problems, and almost 14% reported they "found it hard to stay away from the Internet for several days at a time."

"The Internet problem is still in its infancy," said Elias Aboujaoude, a Stanford professor. No single online activity is to blame for excessive use, he said. "They're online in chat rooms, checking e-mail, or writing blogs. [The problem is] not limited to porn (色情) or gambling" websites. Excessive Internet use should be defined not by the number of hours spent online but "in terms of losses," said Maressa Orzack, a Harvard University professor. "If it's a loss [where] you're not getting to work, and family relationships are breaking down as a result, then it's too much."

Since the early 1990s, several clinics have been established in the U. S. to treat heavy Internet users. They include the Center for Internet Addiction Recovery and the Center for Internet Behavior.

The website for Orzack's center lists the following among the psychological symptoms of computer addiction:

● Having a sense of well-being (幸福) or excitement while at the computer.

● Longing for more and more time at the computer.

● Neglect of family and friends.

● Feeling empty, depressed or irritable when not at the computer. ● Lying to employers and family about activities.

● Inability to stop the activity.

● Problems with school or job.

Physical symptoms listed include dry eyes, backaches, skipping meals, poor personal hygiene (卫生) and sleep disturbances.
