Technology use was clearly interfering with the students' daily lives, but it may be going too far to call it an addiction, says Nicki Dowling, a clinical psychologist who led the study. Ms. Dowling prefers to call it "Internet dependence."
Typically, the concern about our dependence on technology is that it detracts from our time with family and friends in the real world. But phychologists have become intrigued by a more subtle and insidious effect of our online interactions. It may be that the immediacy of the Internet, the efficiency of the IPhone and the anonymity of the chat room change the core of who we are, issue that Dr. Aboujaoude explores in a book, "Virtually You: The Internet and the Fracturing of the Self," to be released next year.
Dr. Aboujaoude also asks whether the vast storage available in e-mail and on the Internet is preventing many of us from letting go, causing us to retain many old and unnecessary memories at the expense of making new ones. Everything is saved these days, he notes, from the meaningless e-mail sent after a work lunch to the angry online exchange with a spouse.
