　　使用不健康网络可能有损心理健康

　　Internet use appears to cause a decline in psychological well-being,according to research at Carnegie Mellon University.

　　Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less frequently, the two-year study showed. And it wasn't that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feelings.

　　Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the Net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others.

　　The fact that Internet use reduces time available for family and friends may account for the drop in well-being, researchers hypothesized. Faceless, bodiless virtual communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that exposure to the wider world via the Net makes users less satisfied with their lives.

　　But it's important to remember this is not about the technology; it's about how it is used, says psychologist Christine Riley of Intel, one of the study's sponsors. It really points to the need for considering social factors in terms of how you design applications and services for technology.

　　根据卡内基麦伦大学的研究，使用因特网可能会导致心理健康程度下降。

　　两年的研究表明，上网次数多的人与较少的人相比，即使是一周仅上网几小时也会经常地感觉到沮丧和孤独。这不是说已经有不良感觉的人在网上花费了更多的时间，而是说使用因特网似乎确实诱发了人们的不良感觉。

　　研究人员对这些结果困惑不解，因为这与他们的预料截然相反。他们预测，和看电视相比，从社交角度来说，上网可能更健康一些因为网络允许使用者选择自己需要的信息并且和别人进行交流。
