| Abstract: | 社群媒體的普及改變了人們汲取資訊、溝通公共事務或討論社會議題的方式。近年，民眾對於爭議性社會議題各持己見，在社群網站上意見分歧導致「回音室」（echo chamber）與網路同溫層的形成，從而導向極端態度。針對社群媒體上的異質性資訊曝露之於態度明確性扮演的角色，過去研究亦有不同論點。有研究認為異質性資訊能夠提高民眾對於不同態度的理解，進而調節民眾對於議題的態度明確性。然而，有研究則指出，根據認知失諧理論（Cognitive dissonance theory），人們傾向接納態度一致的資訊已取得認知平衡。因此，暴露在異質性資訊中，反而會使人們更加確信自身對於議題的態度。本研究旨在探討異質性資訊曝露與態度明確性的關聯性。異質性討論的中介效果及選擇性迴避的調節作用也是本研究探究之重點。本研究採用台灣政經傳播研究中心2018年調查資料，結果顯示社群網路異質性資訊曝露和爭議社會議題態度明確性為正相關，而選擇性迴避在此過程中具有調解作用。然而，異質性討論對於異質資訊暴露與態度明確性的中介效果不顯著，選擇性迴避對於中介效果也無調節作用。本研究啟發了在社群媒體環境下如何理解認知失諧理論，針對未來溝通爭議性社會議題的說服訊息設計，提供一些實際建議。
The prevalence of social media has transformed the way people gather information and hold interactive debates on public affairs. Since public opinion on several social issues is quite divided in Taiwan in recent years, social networking sites (SNS) might form an echo chamber for users, resulting in the extremity of attitude. Recent studies have different discussions on how heterogeneous information exposure plays a role in individuals’ attitude certainty, which is crucial to make SNS a more tolerant field of deliberation. Thus, this study aims at investigating the association between heterogeneous information exposure and attitude certainty. Besides, scholars highlighted the indirect effect of heterogeneous discussion on affecting attitude certainty. By adopting the cognitive dissonance theory, previous research pointed out the potential effects of selective avoidance. Employing the dataset of the Taiwan Institute for Governance and Communication Research (TIGCR) in 2018, the result demonstrates a positive relationship between heterogeneous information exposure and attitude certainty on controversial social issues. Apart from the main effect, the interaction effect of selective avoidance is also identified. When individuals’ selective avoidance on SNS is low, the effect of heterogeneous information exposure on attitude certainty is stronger when it is of high-level selective avoidance. The findings contribute to the understanding of cognitive dissonance theory in the context of SNS and provide future practical suggestions for designing persuasion messages in communicating controversial social issues. |
