ABSTRACT Using the theoretical framework of the Reinforcing Spirals Model, we examine over-time relationships between partisan political discussion and affective political polarization using two three-wave datasets collected during the 2016 and 2012 US Presidential Elections. Our results during both election cycles indicated that higher levels of polarization at wave 1 were associated with an increased discussion with like-minded partners at wave 2, which was associated with higher levels of polarization at wave 3. In all, these findings demonstrate support that reinforcing spirals occur through partisan political discussion on affective partisan attitudes.

加强政治讨论和情感两极分化的螺旋

摘要 利用强化螺旋模型的理论框架，我们使用 2016 年和 2012 年美国总统选举期间收集的两个三波数据集，研究了党派政治讨论与情感政治极化之间的长期关系。我们在两个选举周期中的结果表明，第 1 波的更高水平的两极分化与第 2 波与志同道合的伙伴的讨论增加有关，而这与第 3 波的更高水平的极化相关。总而言之，这些发现表明支持通过党派政治讨论关于情感党派态度的加强螺旋。
