A study on how changes in the media environment influence the public opinion process.

这项研究探讨了由传播技术的快速发展引起的媒体环境最近的变化如何影响舆论过程的问题。更具体地说，我们讨论了如下问题：(A)我们应该如何对公众使用媒体的模式进行分类；(B)媒体使用模式的差异是否会影响人们对公共问题的感知程度；(C)媒体使用模式的多样化将如何影响大众媒体履行其议程设定功能的方式；以及(D)媒体渠道的多元化将如何影响政治异化的程度。

This study explored a question of how recent changes in the media environment, caused by the rapid developments of communication technology, are influencing the public opinion process. More specifically, we addressed such questions as (a) how we should classify patterns of media use by the public, (b) whether the difference in media use patterns would influence the extent to which people perceive public issues, (c) how the diversification of media use patterns would influence the way mass media fulfill their agenda-setting function, and (d) how the multiplication of media outlets would affect the level ofpolitical alienation.
