Diabetes is prevalent among the Latino population in the United States. Engagement in healthy dietary behaviors, especially as a young adult, is an effective means of reducing risk for diabetes. Previous psychological theories have demonstrated that health beliefs and perceived barriers influence engagement in such behaviors. This research investigated beliefs regarding risk for diabetes among the young, educated Latino population. Study 1 of this research sought to compare health beliefs and perceived barriers to barrier change in the young, educated Latino and European American populations. Latinos reported to have a higher perceived vulnerability to diabetes, but shared the belief in diet as the most important determinant of diabetes risk with European Americans. However, Latinos saw their diet as less malleable in their lives than did European Americans. Study 2 sought to replicate these findings and verify the existence of these beliefs. Young, educated Latinos' beliefs in the importance of diet yet a perceived lack of dietary changeability were confirmed. Furthermore, Study 2 evaluated the efficacy of health messages based in the principle of social proof in motivating health behavior change. Social proof, or social validation, describes the phenomenon in which people who see others similar to them engaging in a particular behavior are more likely to engage in that behavior. Latinos who were randomly assigned to receive a health message utilizing the principle of social proof to motivate healthy dietary changes were more likely to express a willingness to change their diet than those who did not receive such a message. These findings can inform the development of health campaigns seeking to promote healthy behaviors among young, educated Latinos.

Description
Predicting when an individual will adopt a new behavior is an important problem in application domains such as marketing and public health. This thesis examines the performance of a wide variety of social network based measurements proposed in the literature - which have not been previously compared directly. This research studies the probability of an individual becoming influenced based on measurements derived from neighborhood (i.e. number of influencers, personal network exposure), structural diversity, locality, temporal measures, cascade measures, and metadata. It also examines the ability to predict influence based on choice of the classifier and how the ratio of positive to negative samples in both training and testing affect prediction results - further enabling practical use of these concepts for social influence applications.

Description
The Internet is a major source of online news content. Online news is a form of large-scale narrative text with rich, complex contents that embed deep meanings (facts, strategic communication frames, and biases) for shaping and transitioning standards, values, attitudes, and beliefs of the masses. Currently, this body of narrative text remains untapped due—in large part—to human limitations. The human ability to comprehend rich text and extract hidden meanings is far superior to known computational algorithms but remains unscalable. In this research, computational treatment is given to online news framing for exposing a deeper level of expressivity coined “double subjectivity” as characterized by its cumulative amplification effects. A visual language is offered for extracting spatial and temporal dynamics of double subjectivity that may give insight into social influence about critical issues, such as environmental, economic, or political discourse. This research offers benefits of 1) scalability for processing hidden meanings in big data and 2) visibility of the entire network dynamics over time and space to give users insight into the current status and future trends of mass communication.

Description
Emotions are an important part of persuasion. Experimental research suggests that White and male jurors can use emotion to increase their influence, while other jurors cannot. This research builds on prior research by examining the relationship between naturally occurring emotion during mock jury deliberations and the influence that jurors hold. Participants (N = 708) in 153 mock juries watched a murder trial video and deliberated on a verdict. Participants self-reported their experienced emotions and rated their perceptions of the other jurors’ emotion and influence. After data was collected, I extracted acoustic indicators of expressed emotion from each deliberation and used a speech emotion recognition model to classify each mock juror’s emotional expression. I hypothesized that there would be an overall effect of emotional expression on influence such that as mock jurors’ emotion increased, their influence would also increase. However, I hypothesized that a juror’s race and gender would moderate the relationship between emotion and influence such that White male jurors will be seen as more influential when they are more emotional, and that female jurors and jurors of color will be seen as less influential when they are more emotional. I also hypothesized that female jurors of color will be doubly penalized for being emotional, due to their “double-minority” status. Bayesian model averaging suggested that the data was most probable under models that included perceived emotion, race, and the interaction between the two, compared to models that did not. Consistent with the hypothesis, as participants were perceived as more emotional, their influence increased. In contrast to the hypotheses, being perceived as more emotional increased influence for both White and non-White mock jurors but the effect was stronger for non-White jurors. In other words, while all jurors benefited from being perceived as more emotional, non-White jurors benefited more than White jurors. Male jurors were more influential than female jurors, and gender did not interact with emotion.. Although being perceived as more emotional predicted increased influence for all participants, this research demonstrates that there are racial and gender disparities in the level of influence that someone might hold on a jury.

Description
Social curiosity, a desire to learn about others, may play an important role in socio-cognitive development in early childhood. However, we poorly understand whether and how social curiosity is elicited. In this study, we examined the malleability of social curiosity in young children by developing a “Social Uncertainty Paradigm.” Children aged 5 to 8 (30 collected, target N = 105) were randomly assigned to one of three conditions (Social Curiosity (SC), General Curiosity (GC), or No Curiosity (NC)) and introduced two learning objectives: the new person (Sam) and new object (Apple House). Participants had 10 chances to gather information about either Sam and the Apple House. In SC, participants obtained 4 times more facts about Sam than the Apple House. The reverse was true for GC. To maximize uncertainty (a lack of information), the experimenter remarked about the difference in the amount of information they gathered. In NC, participants obtained the same amount of facts about Sam the Apple House. Next, participants’ social curiosity were measured with two tasks: Choice Task measuring their preference for learning between Sam and the Apple House and Rating Task measuring the degree to which they want to learn more about both Sam and the Apple House (5-point Likert scale). Preliminary results suggest that creating uncertainty in social information elicits social curiosity and is associated with more active information seeking behaviors to fill the knowledge gap. The current study will provide practical information that could be used for creating social curiosity-promoting environments.
