I am 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.


Current Research
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.
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 features of the socio-ecological environment 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. Currently I am working on a program of research on the relationship between culture and Mu-suppression a correlate of activation in the mirror neuron system.

Cultural Change: A number of studies have documented increases in variables conceptually linked to individualism in the US. To some extent there have been similar developments in other cultures as well. However, it remains unclear which factors may cause cultures to shift in this direction. I am currently working on a project exploring the role various social, demographic, and ecological factors in shaping cultural change.
Some of my other research interests include wise reasoning and the effect of different types of uncertainty on achievement-related behavior.

I am teaching Cultural Psychology (PSY 498) in the spring term. This course is a great opportunity for students interested in learning more about how culture affects the way we think, feel, and behave. The course will provide a broad introduction to cultural psychology as well as cover cutting edge research using new techniques (including genetics and neuroimaging) in the study of culture.
