Xi (Cici) Liu, Ph.D.

Postdoctoral Research Associate (remote)

Cici joined the lab in Spring 2023 and is currently working on two lines of research under the supervision of Dr. Albarracín. The first line of research involves using survey methods to examine drug abuse issues and community coherence in US Appalachian rural communities. The second line of research focuses on the generation, dissemination, and consumption of misinformation online. Cici utilizes a combination of conventional statistical methods and machine learning algorithms to uncover effective interventions for misinformation and improve trust within communities. Cici holds a Ph.D. in Social Psychology from the University of Illinois, Urbana-Champaign, where her research centered on the influence of culture on psychological processes. Specifically, she investigated how linguistic features that may lack concrete meaning influence speakers’ mental representation and evaluation of described objects.

Xi Shen, Ph.D.

Postdoctoral Fellow

Xi Shen studies the social learning processes involved in forming and changing impressions, evaluations, and moral judgments, with an emphasis on the role of implicit cognition. Shen received her Ph.D. in social and personality psychology from Cornell University in 2021. Shen’s work has examined the role of intuitive social cues, such as facial appearances, group memberships, and emotional responses, in shaping people’s impressions of others. She also examines the possibility of changing people’s minds by exploring the type of effective information. She has been especially interested in implicit cognitions involved in these social learning processes, their processing characteristics, and their role in influencing social behaviors. She also studies the social cognitive processes involved in goal pursuit.

Riana M. Brown, Ph.D.

Postdoctoral Fellow

Riana M. Brown is a Joan Bossert Postdoctoral Research Fellow at the Annenberg Public Policy Center (APPC), where she works with Dr. Dolores Albarracín, the Alexandra Heyman Nash University Professor and director of APPC’s Communication Science Division.

Riana completed her M.S. in Social Psychology Research at the Vrije University Amsterdam, which she attended as a Fulbright Fellow, after receiving her B.S. in Psychology and International Studies from the University of Miami. Her research broadly focuses on how people respond to evidence of social inequality, particularly given the intersectional nature of social identity. She is interested in understanding ways to address and mitigate social inequalities and injustices and hopes her work can shed light on how to create greater equity and justice. When she is not discussing or researching social inequality, she can be found biking around, drinking coffee, rock climbing, or practicing handstands in the park.

Javier Granados Samayoa, Ph.D.

Postdoctoral Fellow

Javier Granados Samayoa, the Vartan Gregorian Postdoctoral Fellow at the Annenberg Public Policy Center, earned his Ph.D. in Social Psychology from The Ohio State University. Javier has applied his interest in attitudes and social cognition to the development of several lines of research. In one line of work, he has examined the role of individual differences in attitude generalization tendencies — whether people’s positive or negative attitudes generalize more strongly — in shaping behavior as people pursue their goals. This research has led to the development of a theoretical model of self-regulation in which goal-relevant assessments afforded by the situation (e.g., “am I prepared?”) interact with people’s attitude generalization tendencies to shape judgments about goal-directed behavior. In addition, Javier has explored the consequences of believing specific conspiracy theories (e.g., conspiracy theories about COVID-19). For instance, he finds that believing Covid-19 conspiracy theories predicts increases in conspiracist ideation — the general tendency to believe conspiracy theories — over time. That is, endorsing specific conspiracy theories appears to pave the way for greater receptiveness to a variety of different conspiracy theory beliefs down the road.

His research is centered on beliefs about low-probability, high-impact (LPHI) events like hurricanes and floods: how they are formed, how they evolve over time, and what can motivate changes in protective behavior. At the policy center, Tim is focusing on how attitudes about climate change are shaped by personal exposure to extreme weather events.
