摘要

To test a possible boundary condition for the risk information seeking and processing (RISP) model, this study experimentally manipulates risk perception related to the 2014 Ebola outbreak in a nationally representative sample. Multiple-group structural equation modeling results indicate that psychological distance was negatively related to systematic processing in the high-risk condition. In the low-risk condition, psychological distance was positively related to heuristic processing; negative attitude toward media coverage dampened people's need for information, which subsequently influenced information processing. Risk perception elicited more fear, which led to greater information insufficiency and more heuristic processing in the low-risk condition. In contrast, sadness was consistently related to information processing in both conditions. Model fit statistics also show that the RISP model provides a better fit to data when risk perception is elevated. Further, this study contributes to our understanding of the role of discrete emotions in motivating information processing.
