本研究分析閲聽人在接受媒體不同訊息時所產生的情感狀態年互 作用，以及性別與新聞議題顯著性對上述情態變化的影響。本研究採 三因子實驗設計。獨變項爲情態（正面：負面）、性別（男：女）與 議題（高顯著：低顯者）。參與實驗的受試者爲美國密西根大學206 名學生。受試者先被隨機分派至正面或負面情態組，閲讀一組能引發 期待中情態的新聞，再閲讀一貝「丨略負面的高顯著性或低顯著性新聞。 根據研究結果，閲聽人原始的情感狀態會影響到後續的媒體訊息情感 反應，此情態交互作用應驗了情感的對立過程作用，故分派至負面情 態組的受試者當再接觸到負面屬性的議題新聞時，由於情感強度的削 弱，其後測的情感強度會低於先分派至正面情態組者。上述的情感交 互作用以女性反應得較爲強烈。新聞的議題顯著性對閲聽人則未造成 強度不同的情感反應。

This study aims to analyze how individuals’ affective reactions to various news stories interact with each other, and how sex differences and salience of the news stories play the role in influencing such interactions. The study employs a 2 x 2 x 2 experimental design. The independent variables are affective state (positive vs. negative), sex (male vs. female) and issue salience of the news story (high vs. low). Two hundred and six undergraduate students of the University of Michigan participate in the experiment. Subjects are randomly assigned to the positive or negative affect condition, as well as to the news story of high or low salience. The experimental results show that subjects1 affective reactions to the affect-laden news stories will influence how they react to the subsequent issue stories affectively. Subjects assigned to the negative affect condition do not feel as negative as those to the positive affect condition, when both of them continue to read the issue story with a slightly negative tone. The interaction between the preceding and the subsequent affective reactions reveals a function of the opponent process of affect, and the effect is more manifest in the female students than in their male counterparts. Issue salience of the news story, however, does not have a significant effect on subjects' affective reactions.
