大众传播和人际传播有什么不同点？

答案

参考答案：

大众传播的特点和一般人际传播的不同之处是：

（1）大众传播需要借助特定的传播媒介传递信息，这些媒介的特性各不相同，统称为大众传播工具。

（2）大众传播所传递的信息是公开的、面向社会的；受众则是大量的、匿名的、各不相干的。

（3）大众传播基本上是信息的单向流动，受众是不知其名的，来自受众的信息反馈也是有限的、滞后的。（4）现代科学技术特别是电子技术的飞速发展，使大众传播的信息传递更为快捷与广泛。

（5）大众传播的内容多半是由组织（传播机构）和职业传播者所发布的，而不是由个人发出的。

（6）大众传播还具有强烈的选择性。不仅传播机构对接受对象可有一定的选择，而且受众对传播媒介、传播内容和时闻的选择也有更大的自由度
