Framed within the O-S-R-O-R (Orientations-Stimulus-Reasoning-Orientations-Response) communication mediation framework, this study examines the bi-directional effects of personal message expression on individuals' cognitive elaboration, message learning, and attitudes when exposed to social campaign messages in blogs (anti-drunk driving). Findings from an online-based experiment, expression of personal message (yes and no), and perceived homophily to message audiences (yes and no) revealed that expressing personal messages significantly affects the amount of cognitive effort expended by individuals and message learnt, but only slightly affects their attitudes. The role of perceived homophily varies; significantly affecting cognitive effort but with no significant effects on learning and attitude. Findings show that even though influence on individual attitudes is insignificant, simultaneously receiving and expressing a message online as compared to being mere receivers of messages may impact thinking and learning of the message, at the least. 相似文献

This study investigates comparative optimism—whereby people perceive themselves as relatively invulnerable to risks as compared to others—in the evaluation of online information credibility by children and their parents. Results of a representative national survey of Internet users revealed significant antecedents of children's and parents' comparative optimism, including demographic characteristics, cognitive thinking style, and perceived self-efficacy. Parental optimism was also found to relate to the mediation strategies used to regulate children's Internet use, and comparative optimism in children was associated with tendencies to believe online information and specific evaluation behavior. Findings are considered in terms of their theoretical implications and with regard to the role of parents in children's digital information literacy development. 相似文献
