I am an Assistant Professor at the Department of Psychology at Arizona State University. My work focuses on exploring the sources, mechanisms, and consequences of cultural differences in a variety of psychological processes.
Broadly speaking I am interested in how culture effects the way we view the self, how we experience emotions, and how we perceive and reason about the social and non-social worlds. I am also interested in the causes (both proximal and distal) of within-culture and between-culture variations in these processes. My research combines theoretical frameworks from cultural psychology, evolutionary psychology, and behavioral ecology.
Within-culture variations in Social Orientation and Cognitive Habits: In my research, I study variation in these dimensions by social class within the US and other countries. I have conducted work documenting social class differences in neural responses as well as differences in more traditional implicit and explicit social psychological measures. In addition, I study regional variation within the US in tendencies like conformity that may be linked to voluntary settlement. I am also interested in how factors like pathogen prevalence and other ecological features might underlie regional variations in a broad variety of psychological tendencies and behaviors.
Cultural Neuroscience: I am pursuing research using neuroscience techniques to explore how culture influences the brain and vice-versa. I have conducted research using fMRI and EEG and ERPs to explore the effects of culture (including both national culture and social class) on social cognitive processes including trait inference and empathy, and I have explored how manipulating views of the self (a key dimension of cultural difference) affects empathy and vicarious reward. I have shown that social class affects neural responses linked to empathy and mirroring. I am also using neuroscience to study cultural differences in emotion regulation, self-enhancement, and the process of acculturation.
Cultural Change: In this line of research I have documented cultural shifts in variables ranging from individualism/collectivism, to contempt, to gender equality. Together with my collaborators we have used an ecological framework to understand the causes of these shifts.
Some of my other research interests include wise reasoning and the effect of different types of uncertainty on achievement-related behavior.
