Keywords: culture; social class; cultural change; neuroscience; ecology; evolution
We study how patterns of cultural variation may be understood as responses to changes in basic ecological features, using various methods including surveys, archival data, and EEG.
The cultures we live in shape our minds and our behavior. The Culture and Ecology Lab focuses on how patterns of cultural variation and cultural change may be understood as responses to changes in basic ecological conditions (i.e. population density, pathogen prevalence, resource scarcity). In this line of research, we use frameworks and tools from behavioral ecology, evolutionary psychology, econometrics, big data, and cultural psychology. Using these tools, we believe we may not only be able to explain current patterns of cultural variation and past patterns of cultural change but to forecast future cultural trends. We also use EEG and ERP to study how cultural factors affect neural responses involved in a host of social cognitive processes.
Sound interesting? The lab is always looking for bright, conscientious undergraduates to work as research assistants. If interested, please contact Michael Varnum.
Professor Varnum uses insights from biology to help understand sources of cultural variation and causes of cultural change. In one line of research, he uses frameworks and tools from behavioral ecology, evolutionary psychology, and econometrics to understand the causes of patterns of cultural change and to forecast future patterns of change (including changes in individualism, gender equality, contempt, and lyrical complexity). He also uses ecology as a way to understand patterns of cultural variation. In addition, he uses EEG and ERP to explore cultural variations in a range of psychological processes including empathy, emotion regulation, and mirror responses to others’ motor movements. You can find his full CV here: Curriculum Vitae.
Jung Yul Kwon, Doctoral Student, Social Psychology, Department of Psychology
Yul is a second-year PhD student in Social Psychology. He studies prosocial behavior from cultural and evolutionary perspectives. He is interested in how different ecological factors contribute to divergent beliefs and norms regarding cooperation, as well as impressions of unfamiliar others as potential cooperative partners. His current projects explore the relationship between residential mobility and cooperative strategy in social dilemmas, and whether certain cultural learning biases may be favored under some environmental contexts.
Hannah Bercovici, Doctoral Student, School of Earth and Space Exploration
Hannah is a first-year graduate student in the School of Earth and Space Exploration and Interplanetary Initiative. While her main research at SESE explores the dynamics of volcanic systems, she works with the Culture and Ecology Lab to determine how humans will react to the discovery of extraterrestrial life. Her current project explores the role of culture in the reaction of humanity to ET life.
Cari Pick, Doctoral Student, Social Psychology, Department of Psychology
Cari is a fourth-year PhD student in Social Psychology. Her main area of research takes an evolutionary approach to understanding person perception and intergroup processes. She has projects studying how stereotypes, prejudices, and discrimination relate to one another, how people "test" other potential social partners or new group members, and when/why people exclude certain others from their groups. Cari's research with the Culture and Evolution lab focuses on how certain ecological factors affect people's fundamental social motives, and, in turn, how these fundamental motives affect their subjective well-being.
