Dr. Caren Walker, Principal Investigator
Caren Walker is an Associate Professor of Psychology at the University of California, San Diego. She received her Ph.D. in psychology from the University of California, Berkeley in 2015. Dr. Walker’s research is in the area of cognitive development, examining the various learning mechanisms that underlie knowledge acquisition and change. This work addresses basic questions about the nature of mental representations in human cognition, and she is particularly interested in the early development of abstract reasoning about causality.
Dr. Walker has been named a 2021-2023 Jacobs Foundation Research Fellow!
Alex Rett, Graduate Student
Alex is a sixth-year graduate student in the Department of Psychology at UC San Diego. She received her BSc and MASc from the University of Waterloo in Ontario, Canada where she studied children’s learning and language development. She is broadly interested in how children develop scientific reasoning skills and how cues from the learning environment impact children’s causal reasoning. Currently, her work focuses on children’s recognition of abstract information, such as causal structure, and how recognition of causal structure may facilitate learning during childhood. She is also interested in how different features of the learning environment impact learning, such as visual information and design, prompts to predict or explain, and how children’s expectations of information influences persistence.
Tiffany Wang, Graduate Student
Tiffany is a seventh-year graduate student in the Department of Psychology at UC San Diego. She received her BA and BS in Psychology and Human Biology from UCSD. After graduating, her research mainly focused on autism spectrum disorder (ASD) focused interventions and the implementation of these interventions in community settings. Her current research is focused on causal reasoning in children with ASD. Specifically, she is interested in what mechanisms children with ASD use when reasoning about causality as well as the differences in how they approach physical and social causal relationships.
Salih Özdemir, Graduate Student
Salih is a third-year graduate student in the Department of Psychology at UC San Diego. He received his BA from Bogazici University and MA from Koc University in Istanbul, Turkey. He is interested in how we come up with explanations, and in the sorts of information we seek when we are conceptualizing the causal world. His research explores how children reason, make judgments, and talk about causal relationships.
Rose Reagan, Graduate Student
Rose is a second-year graduate student in the Department of Psychology at UC San Diego. She is broadly interested in how we come to make sense of the social world and our place in it, especially integrating concepts of social identity and group membership. How does who we are influence the ways in which we learn, make decisions, and integrate information? How do we craft representations of complex social categories and hierarchies? Further topics she’s excited about include the interplay between causality and sociality, dynamics of bias, and intersecting identities. Before coming to UCSD, she was Dr. Alison Gopnik’s Lab Manager at UC Berkeley, and she’s (proudly!) from Pittsburgh, PA.
Sophie Mazor, Graduate Student
Sophie is a first-year graduate student in the Department of Psychology at UC San Diego. She received her BS in Cognitive Science from UCSD in 2024. She is broadly interested in how children form and revise their beliefs when faced with uncertainty or inconsistent information. Her research explores how young learners decide when to update their beliefs and how they make sense of uncertainty to develop complex understandings about the world around them. She is also interested in how explanation, agency, and the strength of prior beliefs guide these processes.
Ethan Hurwitz, Postdoctoral Researcher
Ethan is a postdoctoral research fellow in the UCSD Department of Psychology and Center for Psychedelic Research. His work seeks to characterize the cognitive mechanisms underlying psychedelic therapy. He is particularly interested in the role of cognitive flexibility and using cognitive development as a model to bridge the levels of analysis in psychedelic science.
Isabel Sichlau, Lab Coordinator
Isabel graduated from the University of Pittsburgh with a BPhil in Psychology and a BA in Spanish. At Pitt, she worked as an undergraduate research assistant in the Kids’ Thinking Lab examining early math skill development and wrote a thesis on the associations between maternal and paternal spatial talk and their toddlers’ spatial skills. Isabel is broadly interested in math and science learning, specifically in early educational environments.

Collaborating Graduate Students and Postdoctoral Researchers
International Lab Members
The Early Learning & Cognition Lab partners with the Junior Researcher Programme in support of their international apprenticeship for psychology students and young researchers. Our team of student researchers, supervised by Alex Carstensen, explores how language, culture, and cognitive maturation influence the development of relational reasoning. This project examines preschool-age children across five countries that are culturally and linguistically diverse to determine which features of a child’s learning environment shape the developmental trajectory of their early relational reasoning abilities.
