ABSTRACT

This article critically examines long-term media effects in communication research. Focusing on news exposure, the purpose is to provide a review and theoretical conceptualization of long-term effects on societal beliefs. The first part presents an empirical overview of research published in leading communication journals. While longitudinal studies are not uncommon, few have an explicit and elaborated focus on long-term influences. To advance future research, the second part builds on cognitive schema theory to develop three distinct ways of conceptualizing long-term effects: in terms of (a) effect duration, (b) effect mechanisms and (c) effect dynamics. Finally, the third part condenses a comprehensive literature review into a multilevel framework model of factors contributing to long-term media effects on societal beliefs.

摘要

本文对传播研究中的长期媒体影响进行了严格审查。重点关注新闻曝光，目的是对社会信仰的长期影响进行回顾和理论上的构想。第一部分介绍了主要通讯期刊上发表的研究的实证概述。尽管纵向研究并不少见，但很少有人对长期影响进行明确而详尽的论述。为了推动未来的研究，第二部分建立在认知图式理论的基础上，开发了三种不同的概念来对长期效应进行概念化：就（a）效应持续时间，（b）效应机理和（c）效应动力学而言。最后，第三部分将全面的文献综述浓缩为影响长期媒体对社会信仰影响的因素的多层次框架模型。
