假定影响力假说(IPI)是一种解释说服性媒体效果产生过程的传播学理论。本研究整合了说服理论、新媒体效应研究和传统媒体效应研究的理论观点,通过实验研究了IPI的假设和解释机制。社交媒体上的浏览量直接预测了其他人的假定曝光率,间接预测了对其他人的假定影响力,这与IPI一致,但与潮流启发式不一致。假定暴露预测假定影响,与IPI一致。其他预测的假定曝光和假定的影响也被发现。自我的评价的消息(现实主义)和参与的消息(识别)预测假定曝光的其他人和假定的影响他人,支持的预期,IPI的动机机制是自我为中心的社会知觉。社交媒体信息的浏览量并不能直接预测说服力的结果,但是对信息的评价和参与度可以。最后,这些数据与大众媒体普及的假设不一致。这项研究提供了理论上的影响,检查社会媒体信息的说服力,同时提高和扩大IPI。研究的局限性和未来的研究方向进行了讨论。
The influence of presumed influence hypothesis (IPI) is a communication theory accounting for the process of persuasive media effects. The present study integrates theoretical perspectives in persuasion and new and traditional media effects research to investigate the assumptions and explanatory mechanisms of IPI in an experiment. View numbers in social media directly predicted presumed exposure by others and indirectly predicted presumed influence on others, consistent with IPI and inconsistent with the bandwagon heuristic. Presumed exposure predicted presumed influence, consistent with IPI. Other predictors of presumed exposure and presumed influence were also found. Self’s evaluation of the message (realism) and engagement in the message (identification) predicted presumed exposure by others and presumed influence on others, supporting the expectation that a motivational mechanism of IPI is self-centric social perception. Social media message view numbers did not predict persuasive outcomes directly, but the evaluation of and engagement in the message did. Finally, the data were inconsistent with the assumption of pervasive mass media reach. This study provides theoretical implications for examining persuasive effects of social media messages, while enhancing and expanding IPI. Limitations of the study and directions for future research are discussed.
