20･30대의 SNS 네트워크 이질성과 선택적 노출이 이견관여와 투표의도에 미치는 영향: 정향욕구의 조절적 역할을 중심으로

초록

Cross-cutting discussion, which includes responding to disagreeing opinions and expressing their own, plays a significant role in deliberative democracy. Despite its importance, little has been known about predictors of cross-cutting discussion and its effects. Drawing on a survey among the 20s and 30s, this study explores how social network service (SNS) network heterogeneity, selective exposure, and need for orientation might affect the extent of cross-cutting discussion. The effects of cross-cutting discussion on voting intentions in the South Korean presidential election are also analyzed. The results show that network heterogeneity and selective exposure are positive predictors of the level of cross-cutting discussion on SNSs. Need for orientation, a desire to seek helpful information, moderates the relationship between network heterogeneity and cross-cutting discussion. Results suggest that the need for orientation increases the level of voting intentions, while network heterogeneity and cross-cutting discussion attenuate the voting intentions. These results show that the political heterogeneity of the SNS network plays a dual role of increasing cross-cutting discussion but decreasing the voting intention.
