W: Dr. Smith, thank you for coming to our program.
M: My pleasure.
W. When you said that the Internet is causing a decline in psychological well-being, what do you mean by that?
M: Well, psychologically, people are getting more depression and loneliness than before, especially for those who spend long time on the Internet.
W: So if people spend just a few hours a week on the Internet, they would not have the bad feeling then?
M: Not really. (22)Actually, it’s not the long time on the Net that causes them feel bad but the state of being on the Net does.
W: But you said you had much brighter expectations at first.
M: Yes, (23) we supposed that the Net would prove to be socially healthier than television, since the Net allows users to choose their information and to communicate with others.
W: Then, why did the result turn to be completely contrary to your expectations?
M: Well, people on the Net do have more "virtual" communication, but (24)this kind of faceless and bodiless communication is less psychologically satisfying than actual conversation. And they reduce their time being with family and friends. Another possibility is that exposure to the wider world via the Net makes users less satisfied with their lives.
W: The Internet should be found guilty of this phenomenon, right?
M: I don’t think so. (25) It’s not about the technology; it’s about how it is used. It really points to the need for considering social factors in terms of how you design applications and services for technology.
