Principal Investigator

Mahesh Srinivasan, Ph.D. [CV] [Research Statement]

I am an Associate Professor in the Department of Psychology and a member of the Cognitive Science Faculty at the University of California, Berkeley. Previously, I was a post-doctoral researcher in the Department of Psychology at the University of California, San Diego. Before this, I received a Ph.D. in Developmental Psychology from Harvard University in 2011, and received a B.S. in Symbolic Systems from Stanford University in 2005. Using empirical methods from developmental psychology and psycholinguistics, our lab's research explores how linguistic, cognitive, and social abilities arise and interact with one another during human development and across different cultures.

Lab Manager

Grace Horton

Hello and welcome! I’m a recent Berkeley graduate and have been working with the Language and Cognitive Development lab for many years as a research apprentice—now I'm managing it! I find language development in children fascinating and unique, and love learning about how children navigate word polysemy—when words have multiple distinct meanings—as well as how different types of speech input can affect speech development in young children. If you have any questions about the lab—whether it be working in it or participating in one of our studies—please feel free to reach out.

Post Doctoral Researchers

Ye Rang Park, Ph.D.

I’m a postdoctoral researcher supporting the Psychology and Economics of Poverty Initiative at the Center for Effective Global Action with Dr. Mahesh Srinivasan and Dr. Supreet Kaur. I completed my PhD in human development and family studies at the University of Wisconsin-Madison, focusing on resilient parenting in the context of poverty. I am interested in how parents navigate financial hardships and how we can empower parents to help their children develop important early skills for later adaptive cognitive and socio-emotional outcomes. My current research examines how financial scarcity affects family dynamics, including parent-child interactions, inter-parental relationships, and early childhood developmental outcomes.

Graduate Students

Ruthe Foushee

As a graduate student in the LCD Lab, I am interested in what language learners can tell us about the composition of meaning, what their performance on linguistic tasks reveals about their conceptions of language itself, and the implications of those developing linguistic assumptions for methodologies in the field. Many of my projects explore how we negotiate the meaning of vague or subjective language in conversation, and how children leverage their implicit social and statistical knowledge to understand these terms. I am also interested in qualitative differences in linguistic input, experimental methods in linguistic fieldwork, sociolinguistic development, and applications of cognitive science in museums. I am grateful to be funded by the NSF GRFP and the Center for Childhood Creativity.


Monica Ellwood-Lowe

As a graduate student working in the LCD Lab and the Building Blocks of Cognition Lab, I am interested in how children’s early experiences shape their linguistic and cognitive development. Why do some children seem to thrive in school, while others don't? My research integrates what we know about the structure of society with what we know about children's brain development to understand the barriers some children face to success, and how they are able to adapt and thrive in the face of these barriers. I use behavioral, psychophysiological, and neuroimaging methods to help answer these questions. My graduate research is generously supported by the NSF GRFP and the UC Berkeley Chancellor's Fellowship.


Antonia Langenhoff

I am fascinated by the development of normative and linguistic cognition, and how these cognitive abilities interact with our uniquely human social reasoning skills. As a graduate student, I explore the role that engaging in social discourse and argumentation plays for children’s developing cognitive skills. Specifically, I investigate the role of disagreement as a potential mechanism for cognitive development.


Roya Baharloo

I am interested in social cognition in childhood. I am fascinated by how children—even as early as infancy—reason and make sense of our complex social world. Further, I am curious about how this reasoning is shaped by our environment. My current research investigates how children conceptualize and make inferences about social groups. For example, when do children start to endorse common racial stereotypes? I hope my research sheds light on how we can reduce harmful intergroup phenomena, such as bias and prejudice.


Victoria Keating

As a graduate student working in the LCD Lab and the Mind and Society Lab, I am interested in how the people and cultures children are exposed to affect how they think about the world and others. My current research interests are focused on how children learn to think about those that are different from themselves. For instance, how does the way we communicate about race with children shape their concepts of their own race and others? Additionally, I am curious about the multiple ways we can think about diversity and its various impacts.



Hugh Rabagliati, Ph.D.

I am a Chancellor's Fellow in the Department of Psychology at the University of Edinburgh. I became interested in the science of child development as an undergraduate, spent many years training in developmental psychology in America, and returned to the UK to start the RabLab in 2013. I like hiking, pasta, and noodling around the ancient world with my classicist fiancée Monica. I dislike cutting my hair.


Nadya Vasilyeva, Ph.D.

I am a postdoctoral researcher working across three labs (Dr. Mahesh Srinivasan's Language and Cognitive Development Lab, Dr. Alison Gopnik's Cognitive Development Lab, and my primary advisor Dr. Tania Lombrozo's Concepts and Cognition Lab). In my research I explore connections between explanation, inductive inference, and causal reasoning. At the LCD lab, I am currently working on a project on contrast inference (exploring pragmatic inferences about unmentioned categories and attributes) and preparing a study examining structural explanations of speech injustice.


Audun Dahl, Ph.D.

I'm an Associate Professor of Psychology at the University of California, Santa Cruz. Most of my research investigates early moral development. I'm especially interested in how young children begin to help others and come to see it as wrong to harm others. Combining naturalistic and experimental methods, we are studying how these developments take place through social interactions in everyday life.


Yang Xu, Ph.D.

My research concerns the intersection of semantics, cognition and computation. I am particularly interested in how word meanings vary over time and across different languages, and a computational account of these phenomena that explains the underlying cognitive principles.


Alex Carstensen, Ph.D.

I’m a postdoctoral researcher in the Language and Cognition Lab at Stanford University. I completed my PhD in psychology at UC Berkeley and postdoctoral research at Radboud University in the Netherlands, focusing on the nature of category systems across languages: how these semantic structures vary, evolve, and influence thought. My current research examines the joint roles of language and culture in the development of abstract reasoning. I’m collaborating with the LCD lab to study contributions from language to children’s changing conceptualizations of space.


Katharine Tillman

I'm a graduate student from the Language and Development Lab at UC San Diego. I'm interested in how children acquire an adult-like concept of time, and roles that language and spatial cognition play in this process. I also study how kids learn abstract words in general, including time words, number words, and color words. Prior to starting my graduate work at UCSD, I received my BA in Psychology from NYU, where I conducted research on visual perception. Outside the lab, I enjoy creative writing, meditation, and trying to keep up with my 2-year-old daughter.


Andrew Bartnof

I studied English and Philosophy at Pitzer College, lived in Indonesia for a year as a Fulbright Scholar, and spent some time working in the maple forests in Québec. I then worked as a translator, and as a dubbing coordinator at a post-production facility. Now I am a doctoral student at Northwestern University. I love studying the processes that drive language acquisition!


Kelsey Moty

I graduated from UC Berkeley with a B.A. in Psychology and Linguistics and a minor in Polish Language and Literature, and am currently a graduate student at New York University. My research interests revolve around the following questions: 1) How does the language we speak influence how we think about and perceive the world? 2) How do children and adults learn language? and 3) How do children and adults form and revise categories? Currently, I am exploring how children use categories across different domains to make inferences, how they integrate information from multiple sources to form coherent categories, and how they make use of pragmatic information to learn language.


Rachel Jansen

I am a Ph.D. student in the Computational Cognitive Science Lab, advised by Tom Griffiths and Anna Rafferty. I am passionate about employing methods from machine learning and probabilistic modeling to the study of mathematics cognition and education. I am specifically interested in understanding more about how people learn math so that I may work towards improving both teaching practices and online educational tools. One branch of my research is centered around math learning in adults using an online algebra tutor developed by me and my advisors. I am using this tool to explore ways in which we can influence motivation and alter students' perceptions of mathematics, to ultimately remove emotional and psychological barriers so that more people may appreciate and excel at the subject. I am fortunate to be funded by the UC Berkeley Chancellor's Fellowship and NSF GRFP.


Ariel Starr, Ph.D.

I am currently an assistant professor at the University of Washington in the Department of Psychology. I was previously a postdoctoral researcher in the LCD Lab and in Dr. Silvia Bunge's Building Blocks of Cognition Lab. My research investigates how children create new knowledge from existing representations. I’m particularly interested in how language interacts with other cognitive abilities over development to give rise to uniquely human abilities. My lab uses behavioral and eye-tracking methodologies with infants and children to answer questions about the development of memory, language, numerical cognition, abstract concepts, and other topics.


Lena Luchkina

I am currently a postdoctoral researcher in Sandra Waxman's Infant and Child Development Center at Northwestern University. I was a visiting researcher in the LCD Lab and in Dr. Fei Xu’s Berkeley Early Learning Lab from fall 2018 - summer 2019. I received my PhD from Brown University in December 2018, doing my dissertation work with Drs. James Morgan and Dave Sobel. My research focuses on how children learn words and use their social knowledge to make inferences about word meanings. Aside from word learning, I study speech sound categorization in individuals with Autism Spectrum Disorders. As an undergraduate, I studied management and finance but later decided to become a cognitive scientist.


Estelle Berger

I am originally from Portland, Oregon and was previously a student in the Psychology Post-Baccalaureate Program and working in the LCD Lab as a research assistant. Currently, I am working in Ron Dahl's lab in the Institute of Human Development here at Berkeley. Before arriving at UC Berkeley, I attended Brown University and graduated with a bachelor’s degree in Urban Studies. Now, I am very interested in exploring how early life experiences and environments shape one’s sense of identity, cognitive development, and overall wellbeing. My current research focuses on how a child's home environment affects learning and attention.
