Research Interest

"Over evolutionary time, humans had to solve difficult information-processing problems, such as finding food and finding a mate, in an uncertain world. My primary interest is in this human cognitive evolution, specifically, the evolution of human judgment and decision-making capacities. The central questions motivating my research are these: how has the evolutionary process shaped the cognitive mechanisms underlying human decision-making behavior under risk and uncertainty? How do these mechanisms operate in domains such as risk taking, mate choice, and foraging for food and information? To answer these questions, I have adopted an interdisciplinary approach grounded firmly in the theory and methods of cognitive psychology but drawing on ideas from evolutionary biology, behavioral ecology, and anthropology. Appropriately, my training has been interdisciplinary. After completing my diploma in cognitive psychology at the Free University of Berlin, Germany, I joined the International Max Planck Research School LIFE, which emphasizes the study of systematic changes in human behavior over evolutionary and ontogenetic time. LIFE takes an interdisciplinary approach by bringing together doctoral students from such diverse disciplines as biology, psychology, sociology, anthropology, and educational science and provides them with opportunities for collaborative research and supervision at cooperating institutions in the United States, Germany, and Switzerland. In the past, I have been a postdoctoral research fellow both at the Center for Behavior, Evolution, and Culture (BEC), UCLA Department of Anthropology as well as the Konrad Lorenz Institute for Evolution and Cognition Research, Altenberg, Austria. To date, my research has investigated a variety of topics in human cognitive evolution. I have examined, for instance, the question of how risk taking differs across different domains of everyday life, how it should be defined and measured, and how an evolutionary perspective can help explain why young men in particular are very risk prone. My present research focuses on cognitive adaptations underlying decision making under uncertainty in foraging. I have investigated whether the same mechanisms animals use in foraging for patchy resources are also shared by humans and used in novel tasks such as searching for physical resources or information on the Internet. I am also currently investigating whether people bring to bear heuristics or assumptions about the patchiness of resources and whether these underlie certain well-known phenomena of human judgment, such as the “hot hand” fallacy. In this research, I have expanded my methods to include cross-cultural comparative experiments in a foraging society in Amazonian Ecuador. I am an active collaborator with researchers in adjacent disciplines and regularly interact with other fields of psychology by applying my findings, for example, to research in developmental and clinical psychology"
