Computational Approaches and Message Effects Research (CAMER)

The Computational Approaches and Message Effects Research (CAMER) group, directed by Sijia Yang, studies persuasive messages as they are produced, promulgated, and processed in the broader digital informational environment. Our group is particularly interested in exploring how computational methods (e.g., text mining, computer vision, algorithms, geospatial modeling) can help advance our understanding of how persuasive messaging works as it intersects with psychological processes, social dynamics, and technological affordances. Currently, we are focusing on the following lines of research: 1) visual persuasion and the feasibility of employing computer vision techniques to predict and explain the persuasiveness and share-worthiness of pictorial substance control messages (e.g., emerging tobacco products, recreational use of cannabis); 2) the temporal and geospatial dynamics of moral appeals and their persuasive impacts around emerging and oftentimes controvertial health issues (e.g., the COVID-19 pandemic, vaccination, CRISPR); 3) misinformation classification and correction, especially the joint impacts of messages and social dynamics on peer fact-checking; 4) just-in-time message tailoring in mhealth interventions (e.g., opioid addiction treatment, COVID-19 mitigation); and 5) the persuasiveness of positive appeals (e.g., hope, transcendence).

CAMER publishes “Twitter as research data: Tools, costs, skill sets, and lessons learned”

In the new article “Twitter as research data: Tools, costs, skill sets, and lessons learned” in the journal Politics and the Life Sciences, the Computational Approaches and Message Effects Research (CAMER) group evaluates Twitter data collection tools in terms of costs, training, and data quality as a means to introduce Twitter data as a research tool Abstract: Scholars increasingly use Twitter data to study the life sciences and politics. However, Twitter data collection tools often pose challenges for scholars who are unfamiliar with their operation. Equally important, although many tools indicate that they offer representative samples of the full Twitter … Continue reading

MCRC Faculty Leaders Win 2020 Fall Research Competition Grant

MCRC Faculty Leaders Chris Cascio, Communication, Brain and Behavior (CBB) Lab Faculty Leader, and Sijia Yang, Computational Approaches and Message Effects Research (CAMER) Group Faculty Leader, are co-PIs on a new project, “Developing and Testing the Impacts of Cannabis Prevention Messages for At-Risk Young Adults”. They have received funding for their proposal submitted to the 2020 Fall Research Competition. Abstract: The proliferation of legalizing recreational use of cannabis products, combined with shifted public perceptions and youth-appealing marketing has put young adults at high risk for cannabis use initiation and progression into disorder. Despite that early onset of regular cannabis use is … Continue reading

New Fact-Checking Projects Focus on Combating COVID-19 Misinformation

With information about COVID-19 rapidly circulating online, it can be difficult to determine what’s true and what’s not. Social media has made it even easier for misinformation and disinformation to spread unchecked. Knowing whether a claim or a source is reputable can be daunting, even for the savviest media consumers. As the UW-Madison community of students, faculty and staff begin to plan their return to campus, having a verified and reliable source for information will be crucial to maintaining everyone’s health and safety. One such source is the COVID-19 Wisconsin Connect app. Developed by a collaboration of campus groups, COVID-19 … Continue reading
