Director
Tsinghua University Child Cognition Center
A native of Indonesia, Stella received her B.A. from Harvard University in 2004, and Ph.D. from Northwestern University in 2010. Prior to moving to Tsinghua, she was a tenured associate professor at Swarthmore College.
Stella researches the Relational Mind: how cognitive systems learn relations and structures of the world. Using behavioral data from young human children and great apes, Stella’s work has discovered tantalizing similarities and differences between humans’ and other animals’ relational cognition. Eventually, her aim is to chart the precise learning algorithms that any mind uses to abstract relations. Having lived in six countries on all hemispheres, Stella holds a special interests in how relational reasoning is influenced by and influences language, culture, and social interactions.
In her spare time, Stella loves to scale mountains and languages—she currently speaks 5 languages

Graduate Students

Yang Gao
She is a Ph.D. candidate in the Department of Psychological and Cognitive Sciences at Tsinghua University. Her research is dedicated to exploring the spontaneous generation of analogies in explanations. By comparing the explanations given by human parents and large language models to children’s questions, she investigates: Are analogical explanations superior to other types of explanations? What factors influence the generation of analogical explanations during the explanation process? What can promote the spontaneous generation of more analogical explanations?

Jinyun Lyu
She is a PhD candidate in the Department of Psychological and Cognitive Sciences at Tsinghua University. Her research focuses on children’s play and cognitive development. Can children learn through play? What behaviors and factors during play can enhance learning? Does the availability of play opportunities in a child’s environment directly influence their ability to learn through play? Additionally, she is actively involved in building child-friendly cities.

Qiuchen Ma
She is a Doctoral student in the Department of Psychological and Cognitive Sciences at Tsinghua University. Her current research focuses on the rule learning ability of children, adults and AI. What kind of things can people learn rules from? What kind of limitations does the learning of rules face? Are the rules and forms that people learn completely abstract? Her research is dedicated to exploring the influencing factors of rule learning ability and helping people better learn abstract rules from specific things.

Yijin Fang
She is a PhD candidate in the Department of Psychological and Cognitive Sciences at Tsinghua University. Her research focuses on individual’s exploratory behavior in the uncertain contexts. She is working on understanding: what kind of exploration strategies individuals adopt to cope with uncertainty? How do internal (e.g., knowlegde states; confidence) and environmental factors (e.g., time pressure; diversity and complexity) influence people’s exploration? and what is the developmental trajectory of these exploratory strategies?
