摘要:本文运用的研究方法主要有观察法、文献研究法、个案研究法等研究方法。新浪微博作为本文的研究对象，对微博的传播效果进行分析。简要介绍了微博的概念与微博发展。微博的特点有很强的自主性和选择性、影响力有弹性、短小精悍、信息共享迅速便捷。微博与传统媒体的比较。微博与传统媒体相比的优势：发布自由、发布迅速、人性化互动、内容丰富。微博与传统媒体相比的劣势：虚假信息、缺乏权威性、缺乏深度。本文的主要内容是对微博的传播效果进行分析。微博对“议程设置”功能的影响，微博虽然和传统媒体一样具有“议程设置”功能，但是在微博上“议程设置”功能对人的影响比在传统媒体上低。微博对“沉默的螺旋”的影响，在微博上虽然同样存在“沉默的螺旋”，但是与传统相比，微博上的“沉默的螺旋”对人的影响相对较低。在使用微博的过程中，人与人之间的“知识沟”会越来越大，而不是越来越小。微博由于具有简单易操作等特点，使微博特别适合虚假信息的传播，微博上的虚假信息比传统媒体上更多。微博与传统媒体一样，对客观现实的反映不是“镜子”式的再现，而是形成一个“拟态环境”，用户根据“拟态环境”从而产生行动。微博是人体的延伸，微博扩展了人的认识能力，使人的视觉、听觉、抽象思维能力都得到延伸。

微博的使用非常方便，在任何时候任何地点都能发表微博，比传统的媒体更加及时。在新闻的报道发面，微博往往可以在新闻现场同步进行报道，使新闻在第一时间传递给受众，使新闻更加具有及时性。微博用户都是一些普通网民，没有像专业的记者或者编辑一样经过严格的训练，所以在报道新闻方面和发表一些对某些事情的看法的时候，难免会以偏慨全，脱离事实真相。另一发面，虽然微博用户没有经过专业训练，但是反而能不受规则的束缚，可以从各个角度看待问题，得出各种各样的结论。这是一些微博传播比较明显的效果，但是却不是最重要的效果。最重要的效果是对微博用户心理和思维模式的影响，在微博的影响之下，人们的心理和思考问题的方式发生了变化，甚至对人的潜意思也有影响，人在不知不觉中按照“微博思维”思考问题，这是一种“碎片化”的思维模式，把各种像碎片一样的信息融合在一起，形成自己的看法。这与传统的“推理”和“演绎”的思维模式截然不同。
