No Escape from Modality: Impact of Video vs. Text on Perceived Credibility and Engagement with MisinformationTran, Jacinta T 05 1900 (has links)
Misinformation remains pervasive in digital platforms, shaping how individuals receive news online. Prior work suggests that credibility perceptions of misinformation can differ based on the modality of the misinformation message. Informed by the MAIN model, this quantitative study conducted two separate 2 (Modality: video or text) x 2 (Social endorsement cues: high vs. low) between-subject experiments to assess the influence of message modality and social endorsement cues on misinformation credibility judgments. The experiments reviewed two different topics of misinformation: artificial intelligence technology malfunction (N = 296) and a cure for cancer (N = 306). Results for Study 1 on artificial intelligent technology malfunction misinformation indicated that participants who viewed the video modality judged a higher perception of source expertise and message credibility. The results of Study 2 suggested that the text presentation of health misinformation prompted higher message elaboration relative to the video conditions. Findings suggest that modality does influence how people judge misinformation messages depending on the subject matter. In addition, source credibility influences how people judge message credibility. The paper concludes with a discussion of theoretical implications and practical applications.

Social Media And Credibility Indicator: The Effects Of Bandwagon And Identity Cues Within Online Health And Risk ContextsLin, Xialing 01 January 2016 (has links)
Three studies were conducted to investigate how social media affordances influence individuals’ source credibility perceptions in risk situations. The MAIN model (Sundar, 2008), warranting theory (Walther & Parks, 2002), and signaling theory (Donath, 1999) served as the theoretical framework to examine the effects of bandwagon cues and identity cues embedded in retweets and users’ profile pages for health and risk online information processing. Study One examines whether bandwagon heuristics triggered by retweets would influence individuals’ source credibility judgments. Study Two investigates how bandwagon heuristics interact with different identity heuristics in credibility heuristics on an individual level. Study Three explores bandwagon heuristics at the organizational level. Three post-test only experiments with self-report online surveys were conducted to investigate the hypothesis and research questions. Results indicate that different online heuristic cues impact the judgments of competence, goodwill, and trustworthiness at different levels. Authority strongly influenced source credibility perceptions. A reverse-bandwagon effect was observed in influencing source credibility judgments. Theoretical and practical implications are discussed.
