The function of credibility in information processing for risk perception.

Abstract: This study examines how credibility affects the way people process information and how they subsequently perceive risk. Three conceptual areas are brought together in this analysis: the psychometric model of risk perception, Eagly and Chaiken's heuristic-systematic information processing model, and Meyer's credibility index. Data come from a study of risk communication in the circumstance of state health department investigations of suspected cancer clusters (five cases, N = 696). Credibility is assessed for three information sources: state health departments, citizen groups, and industries involved in each case. Higher credibility for industry and the state directly predicts lower risk perception, whereas high credibility for citizen groups predicts greater risk perception. A path model shows that perceiving high credibility for industry and state-and perceiving low credibility for citizen groups-promotes heuristic processing, which in turn is a strong predictor of lower risk perception. Alternately, perceiving industry and the state to have low credibility also promotes greater systematic processing, which consistently leads to perception of greater risk. Between a one-fifth and one-third of the effect of credibility on risk perception is shown to be indirectly transmitted through information processing.

The Persona Effect: How Substantial Is It?

Abstract: Personification of interface agents has been speculated to have several advantages, such as a positive effect on agent credibility and on the perception of learning experience. However, important questions less often addressed so far are what effect personification has on more objective measures, such as comprehension and recall, and furthermore, under what circumstances this effect (if any) occurs. We performed an empirical study with adult participants to examine the effect of the Ppp Persona not only on subjective but also on objective measures. In addition, we tested it both with technical and non-technical domain information. The results of the study indicate that the data from the subjective measures support the so called persona effect for the technical information but not for non-technical information. With regard to the objective measures, however, neither a positive nor a negative effect could be found. Implications for software development are discussed.

Knowledge transfer within information systems development teams: Examining the role of knowledge source attributes

Abstract: Knowledge transfer is considered to be an important topic for both researchers and practitioners. However, very little research has been pursued to understand the factors affecting knowledge transfer within teams, an important social unit within organizations. This study attempts to fill this void by examining factors that affect knowledge transfer within information systems development (ISD) teams. Taking a ''connectionistic'' epistemological perspective and drawing on the communications-based research on knowledge transfer, the theoretical model of the study proposes that the source's capability, credibility, and extent of communication will play an important role in determining the extent of knowledge transferred to recipients. Results from an empirical study involving student teams engaged in semester-long ISD projects supported the role of credibility and extent of communication. Interestingly, capability was not found to play a significant role in knowledge transfer. Possible explanations for this lack of significant effect of capability on knowledge transfer are presented.

Comparative Advertising Effectiveness: The Role of Involvement and Source Credibility

Abstract: Previous research on the persuasive impact of comparative advertising has produced inconsistent results. Consequently, researchers have suggested lack of credibility and the need for higher involvement as two problems which might impede the persuasive impact of comparative advertising. However, virtually no empirical evidence comparing the effects of comparative advertising to non-comparative advertising when different levels of involvement are activated exists. In addition, little research has examined whether source credibility enhances the persuasive impact of comparative advertising. Attribution theory provided the framework for the experiment reported in this paper. Experimental results suggest that when higher involvement is activated and a source of higher credibility is included in the advertisements, comparative advertising for a new brand has a more positive effect on purchase intentions than non-comparative advertising.

Comment: Concerns in the Analysis of Focus Group Data

Abstract: The most frequent concern in qualitative research is an inadequate description of the analysis process, and the consequent limitation on credibility and usefulness of the results. Of all the aspects of using the focus group technique—advantages and limitations, logistics, implementation, and interpreting and reporting of results—the process of analysis is the least agreed on and the least well developed. There is little guidance for researchers, journal editors and reviewers, graduate students and their advisors. A frequent question is "how to do" analysis of focus group data, especially analysis worthy of federal-level funding or acceptable at the level of an academic dissertation. Definitive, mutually agreed on technique does not exist. Decisions in analysis depend on many factors, and this article will discuss considerations in planning and implementing analyses of focus group data.
