 Graduate Students


Wouter Wolf

Wouter Profile PicWouter is a fifth year graduate student in the Tomasello Lab. He received a BSc in Criminology and a BSc in Psychology at Leiden University in the Netherlands, after which he graduated Cum Laude (with honors) from the Research Master’s (MSc) program in social psychology at the Vrije Universiteit in Amsterdam. He then conducted research for a year at the Social and Evolutionary Neuroscience Research Group, supervised by Professor Robin Dunbar at the University of Oxford, and subsequently returned to the Vrije Universiteit in Amsterdam to conduct fMRI research and teach undergraduate content and methods/statistics classes. Wouter’s current research is aimed at exploring what it is in human psychology that makes us so different from other animals (specifically apes). Specifically, he is interested in how the interplay between cognition (i.e., joint attention and shared intentionality) and motivation causes humans to engage in complex cooperation and large scale social cohesion, and, ultimately, social learning and cultural transmission. His projects are funded by Duke University and by an international Fulbright scholarship awarded in the Netherlands.

 


 

Leon Li

Leon is a fourth year graduate student in the Tomasello Lab. He received a BS cum laude in psychology from the University of Maryland, where he investigated language representation with Dr. L. Robert Slevc and moral development with Dr. Melanie Killen. Before attending Duke, Leon also conducted research on mindfulness meditation and language at the Center for Advanced Study of Language and worked as a lab manager for Dr. Susan Courtney at Johns Hopkins University. At Duke, he is excited to continue investigating topics related to language and morality, such as how the linguistic framing of a situation influences children’s actions and interpretations of events or how children engage in moral reasoning when interacting with other people. 

 

 


Jared Vasil

Jared is a third year graduate student in the Tomasello Lab. Under the mentorship of Dr. M. J. Farrar, Jared received a BS in Psychology (summa cum laude), a BA in Linguistics (cum laude), and a minor in Philosophy from the University of Florida. Broadly, Jared’s interests are in the evolution and development of human communication and cooperation. Jared’s experimental work studies the effects of ‘we’-framing on preschool children’s cooperation with a partner (i.e., the effects of describing a dyadic activity as a collaborative, joint venture on children’s social behavior). Additional work relates the active inference formulation of biological systems to human communication. In his spare time, Jared enjoys running, rock climbing, and reading.
