Tweeting Fast Matters,But Only if I Think About It: Information Updates on Social Media

Social media have emerged as increasingly important sources through which the public seeks information concerning crises or risks. Despite this increased dependence, little is known about the psychological processes associated with perceptions of source credibility or the desire to seek additional information related to the risk. The current study investigates the role of speed of updates in credibility perceptions and information seeking using Twitter. The results do not provide evidence of a direct relationship between update speed and the outcomes under consideration. They do, however, consistently support a mediation model in which cognitive elaboration mediates the relationship between update speed and perceptions of sender competence, goodwill, trustworthiness, and reader (follower/audience/rater/target) desire for additional information. These findings are discussed in terms of their implications and applied use.
