Research Interests
My research integrates motivation science, prejudice and intergroup relations, and social cognitive neuroscience. Broadly, I am interested in how the source of motivation (i.e., is motivation internal/autonomous or externally pressured/controlled?) underlying beliefs, attitudes, and behavior shapes the successful self-regulation of those beliefs, attitudes, and behaviors. I have examined the effects of motivation on attitudes and behavior in various domains – including intergroup dynamics, pro-environmental behavior, and education.
In one line of research, I explore the motivational factors that reduce prejudice and promote positive intergroup perceptions and interactions. My work suggests that when the social context is controlling and prescriptive regarding prejudice reduction and diversity practices, prejudice and negative intergroup attitudes ironically rise. On the other hand, social contexts that promote personal choice and autonomous motivation toward diversity appreciation tend to be effective in improving intergroup attitudes.
In a related line of work, I investigate how motivational factors influence not only outgroup perception, but ingroup perception and group identity. Some of my recent work has shown that individual differences in motivational orientation shape the manner in which people identify with their social groups (e.g, being male, being black, being German). I also assess the role of motivational orientation in the capacity to integrate conflicting aspects of one’s social identity, and its role in improving intergroup attitudes and reducing prejudice and discrimination.
In a third, more general line of research, I take a closer look at the basic mechanisms underlying the link between motivation and self-control. My work suggests that personal autonomy (as opposed to social coercion) actually improves executive control processes, such as response inhibition and error monitoring. Moreover, using a neuroscientific approach, I demonstrate that these effects are mediated by increased activity of the anterior cinglulate cortex – a neural structure that regulates bodily states of arousal in order to execute effective control and self-regulation.
Finally, I am actively involved in the design and implementation of a long-term field experiment that investigates the impact of motivation and goal-setting interventions on university students’ pro-environmental behavior, including daily energy and resource use measured using sensor technology in green student housing.
