17 pages., Lab grown meat is a new technology being developed as a potential alternative protein source. Although some research has been done about public perception of lab grown meat, no studies to date have observed the effects of message themes on public perception of lab grown meat. The study sought to better understand measures of uncertainty and risk and benefit perceptions after viewing a themed blog post about lab grown meat. Participants were randomly assigned one of three themed blog posts - against lab grown meat, neutral, or support lab grown meat. Perception questions were asked after viewing the blog post, and a total of 238 responses were collected. Results indicated the message theme had a statistically significant effect on risk perception, benefit perception, and intention to consume, but not on message evaluation or measures of uncertainty. Further discussion as well as suggestions for future research are included.

98 pages., ISBN: 9780438072190, Via ProQuest Dissertations and Theses., This study explored how preexisting values influence attitudes about GMOs and if aligning messages about GMOs with these values would lead to a greater chance of central processing, and subsequently, greater alignment with message-congruent attitudes. Utilizing the Elaboration Likelihood Model as a theoretical foundation, an online experiment was used to measure several values of participants, including altruistic, biospheric and egoistic value orientations as well as agricultural identity. Attitude accessibility and pre- and post-opinions were also measured in order to determine how much of an effect the presented stimuli had on the participants. All participants were presented with a stimulus that either aligned or didn’t align with their self-ranked GMO value-argument. It was found that attitude accessibility, agricultural identity and in some cases a biospehric value orientation were the most important predictors for a number of constructs related to GMO attitudes. In addition, agricultural identity did not correlate with any other value orientation, yet was the strongest predictor of many related attitudes. Future research should continue to explore the complexity of values within agricultural communication contexts and expand the understanding of how agricultural identity influences such outcomes.
