本文提出“选择螺旋”(selective spiral)理论，以图包容、总结、调整、延伸、链接、 融合和运用实证主义传播学中的经典理论，以及心理学、社会学、消费者行为和其他涉 及信息传播的理论。本文将指出，选择螺旋最大限度地包容多种理论，因而是一个大理 论；选择螺旋包含关于理论的理论，因而是一个元理论；选择螺旋可用于预测尚未观测 到的传播行为与传播现象，因而是一个预测理论；选择螺旋可以作为一个预设的框架来 帮助解释已观察到的传播行为和传播现象，因而是一个预设理论。

This research introduces the theory of selective spiral. The theory attempts to connect, integrate, expand, and apply the classic empirical theories of communication research, therefore a mega theory. It includes a theory of communication theories, therefore a meta theory. It makes predictions about communication behavior and impact that can be tested empirically, therefore a predictive theory. Finally, it provides a framework of understanding that flls the gaps between empirical observations, connects dots, explains causes, and interprets meanings, therefore a presumptive theory.
