電視新聞戲劇化效果研究：由議題設定與收視動機角度來看

A Study on Effects of Dramatized Television News: From Perspectives of Agenda Setting and Motivations for TV News Viewing

本研究以議題設定及收視動機角度探討電視新聞戲劇化的效應。由電視新聞內容分析及全國民眾調查的結果顯示，電視新聞議題顯著性與公眾議題的顯著性無關，且在議題戲劇化程度與公眾議題的顯著性上，只有觀點衝突程度提高了議題在公眾心中的分量。本研究也證實觀眾電視新聞注意程度愈高，其議題多樣性，即對議題的重要性認知也愈為多元。以收視動機而言，觀眾資訊需求動機愈強者，議題多樣性則愈高。根據以上結果推論，電視新聞對於議題的戲劇化處理不見得有助於觀眾對新聞議題的認知。

This study aims to investigate the plausible relationship between dramatized issues on television news, motivation of television viewing, and their effects on issue perception of television viewers by combining agenda setting and the motivation of TV news use as a theoretical framework. A quantitative content analysis of the prime time television news and a national survey were used to obtain public's most important problems facing Taiwan, their television viewing patterns as well as the motivation of watching television news. The results indicated that, overall, there was no significant correlation between the television's agenda and viewers' agenda. However, conflict frames of issues on TV enhanced their importance among public agenda. Attention to TV news positively predicted issue divergence. The result also indicated thatpeople with information seeking motivation bear more issues than people with motivation of escape and entertainment-seeking. Based on the results, dramatized TV news does not necessarily help viewers on issue cognition.
