    Abstract: 本研究採線上問卷調查法（N=645），以美國民眾為例，探討選擇性接觸、社交媒體政治意見表達、自我審查與政治極化之關聯性。研究結果發現，選擇性接觸與社交媒體政治意見表達間具有正向關聯性，選擇性接觸與自我審查間具有正向關聯性，自我審查與社交媒體政治意見表達間具有正向關聯性，而自我審查中介選擇性接觸與社交媒體政治意見表達間之關聯性。此外，政治極化調節弱化自我審查與社交媒體政治意見表達之正向關聯性，另一方面，政治極化有條件的調節選擇性接觸與線上政治意見表達之正向關聯性，即當政治極化增加時，將增強選擇性接觸與社交媒體政治意見表達之正向關聯性。
    Employing online survey data (N=645), this study examines the relationship between selective exposure, social media political expression, self-censorship, and political polarization for Americans. The results indicate a positive association between selective exposure and social media political expression. Selective exposure is positively associated with self-censorship. Self-censorship is positively associated with social media political expression. Self-censorship is found to mediate the association between selective exposure and political expression on social media. In addition, political polarization serves as a moderator that decreases the positive association between selective exposure and social media political expression. On the other hand, the positive association between selective exposure and social media political expression is conditioned by the level of political polarization. That is, the association between selective exposure and social media political expression is stronger among those who are highly political polarized.
