21 pages., via online journal., Scholars are divided over whether communicating to the public the existence
of scientific consensus on an issue influences public acceptance of the
conclusions represented by that consensus. Here, we examine the
influence of four messages on perception and acceptance of the scientific
consensus on the safety of genetically modified organisms (GMOs): two
messages supporting the idea that there is a consensus that GMOs are safe
for human consumption and two questioning that such a consensus exists.
We found that although participants concluded that the pro-consensus
messages made stronger arguments and were likely to be more
representative of the scientific community’s attitudes, those messages did
not abate participants’ concern about GMOs. In fact, people’s premanipulation attitudes toward GMOs were the strongest predictor of of our outcome variables (i.e. perceived argument strength, post-message GMO
concern, perception of what percent of scientists agree). Thus, the results
of this study do not support the hypothesis that consensus messaging
changes the public’s hearts and minds, and provide more support, instead,
for the strong role of motivated reasoning.
9 pages., Via online journal., Intergenerational environmental communication (IGEC) was examined using pre- and post-survey research after child participation in a groundwater environmental education (EE) program. The EE program increased child knowledge, but did not significantly increase parent knowledge. There was also a significant difference between perceived levels of environmental communication (EC) between child and parent, with parents indicating higher levels of EC than their children. Participants reporting low EC levels had significantly less interest in, concern for, or knowledge about environmental issues. Several key factors initiated IGEC between children and their parents, including saving household money by changing environmental behaviors, exposure to media sources that reported environmental news, and school activities such as homework related to environmental issues. Environmental educators should be cautious when implementing EE programs, as additional considerations are essential to determine what influence, if any, child participants have beyond the classroom. Continued research is needed to increase EC between children and their parents with the hope of improving intergenerational approaches to environmental issues.
12 pages., via online journal, We examined how information from multiple communication channels can inform social norms about local food purchasing. The concept of social exposure was used as a guide. Social exposure articulates how information in social, symbolic, and physical environments contributes to normative perceptions. Data was collected from a sample in Wisconsin. Results indicated that information from communication channels representing symbolic, social, and physical environments all contributed to normative perceptions. We also found that for individuals who frequent farmers’ markets, information from some communication channels was relatively less strongly associated with injunctive norms. It may be that when first-hand, experiential information is available to inform norms, individuals rely less on information available through other communication channels. Future work might further explore how farmers’ markets foster information sharing in communities, as such information may contribute to normative perceptions.
