“…For example, participants who first read a negative opinion about GM foods given by a layperson might be less interested in positive expert information that is subsequently read than those who read the same opinions in the opposite order, which could result in lower integration of one of the texts. However, the specialty of author information may provide an opportunity to overcome this perseverance (Briñol & Petty, 2009;Cialdini & Goldstein, 2004;Tormala, Briñol, & Petty, 2006). Thus, our second research question was: "Does the status of author information affect inter-text comprehension?"…”

This study investigated whether source information attached to texts influences multiple-text comprehension about genetically modified (GM) foods-a controversial science topic. Participants in the experiment read two texts from two sources: an expert and/or a layperson. When the two texts presented different attitudes toward GM foods (Experiment 1), expert information facilitated intra-text comprehension. Moreover, expert information was better integrated with other information; when expert information was presented first, later information was less integrated with participants' understanding, and when expert information was presented last, it was more integrated. When the two texts presented common attitudes (Experiment 2), a similar pattern of effects was observed, but the effects were weaker than those in Experiment 1. Thus, expert source information has the potential to affect the comprehension of scientific information, and careful planning is required for effective risk communication.

“…Source credibility is based on the idea that people judge information not only on its own merits, but also by people's impressions of the individual who provides the information. Generally speaking, sources that are considered credible are more likely to persuade people than sources that are not credible (although, see Tormala, Briñol, & Petty, 2006 for a reversal of this effect). This has been demonstrated for sources that are honest versus sources who are dishonest (Mills & Jellison, 1967;Priester & Petty, 1995), as well as sources who are experts versus sources who are not (DeBono & Harnish, 1988;Rhine & Severance, 1970).…”

Source credibility and syllogistic reasoning

Two experiments examined whether a source credibility effect would be observed for a syllogistic reasoning task. In the experiments, people were given two statements, presented as the results from a survey, followed by a conclusion that was supposedly made by one of two sources. In Experiment 1, one of the sources was described as honest and the other as dishonest, and in Experiment 2, one of the sources was described as an expert and the other as a non-expert. Because a pilot experiment showed that credibility can be overridden by people's experience with a source, all conclusions in Experiments 1 and 2 were ones that were likely to be accepted (i.e., necessary and possible strong conclusions). Both experiments showed a clear source credibility effect, particularly for the invalid conclusions. These results, along with the belief bias effect and previous research with conditional reasoning, suggest that people can be influenced by extraneous context, such as the honesty or expertise of a source, in a syllogistic reasoning task.

“…H5: Perceived knowledge quality has a positive effect on trust Perceived source credibility refers to the perception about the source of information and knowledge, namely whether the source is expert and trustworthy (Tormala et al, 2006). In the context of health knowledge, perceived source credibility sometimes may have a stronger effect on the attitude when recipients are in low level of health literacy, in particular under the pressure of health risk and limited time (Chou et al, 2015).…”

Abstract:The communication of health knowledge in social media plays an important role in public health literacy and health behavior promotion. But with the accumulation of user-generated health information in social media, more and more misleading health information, health gossip and health rumors are inhibiting the communication of health knowledge and breaking the balance of information ecology in social media. This study focuses on the information ecology in social media and contributes to the communication of health knowledge in social media ecology, highlighting the characteristics of health knowledge and the special Chinese culture. A communication explanatory framework was constructed and 319 samples were tested leveraging PLS. The results indicate that fear communication and trust communication both act as effective communication forms contributing to the communication of health knowledge; face communication acts as a barrier constraining the trust communication while no effect on fear communication.
