Team Members
Principal Investigator
Dr. Stephanie Denison

Stephanie is the director of the Developmental Learning Lab. She studies infant and early childhood cognition, mostly as it relates to how children learn and integrate multiple types of information in their inferences. Current topics of interest in the lab include infant probabilistic reasoning, how children attribute preferences to others, the development of heuristics and biases, how children use probability to infer others’ emotions, the cues that infants use to detect agency, and multi-modal ratio abstraction.
Post-Doctoral Researchers
Dr. Elizabeth Lapidow

Liz is a postdoctoral researcher in the lab. She is interested in how learners seek to figure out the world around them by taking actions and considering possibilities. Her research looks at learning and reasoning about causality and how learners make decisions during exploration.
Lab Coordinators
Paige Wahl

Paige recently graduated from the University of Waterloo with a Bachelor of Arts in Psychology and a research-intensive specialization, and is now the Research Coordinator with the Developmental Learning Lab. She is interested primarily in continuing her thesis work in the domain of causal reasoning. Outside the lab, she spends her time organizing the KW Kids with Cancer Charity Run/Walk!
Daniel Agostino

Daniel is currently completing his Bachelor of Science (BSc) in Honours Psychology at the University of Waterloo and is currently in his fourth year of the program. He is interested in how technology use affects children's language development. Outside the lab, Daniel enjoys reading, solving sudoku and going to the gym!
Graduate Students
Candice Rubie

Candice is a second-year PhD student in the lab, and completed her BA, MASc, and MA in Psychology at the University of Waterloo. Her research looks at how children use the Approximate Number System to estimate quantities, the development of negativity biases in learning and attitude formation, and frameworks to give more effective failure feedback. Outside of her research, Candice loves baking sourdough and reading every genre of book possible!
Ayshe Ozlu

Ayshe is a second year student in the Master of Arts program, pursuing a degree in Developmental Psychology. She completed her Bachelor's at The University of British Columbia with a double major in Psychology and Film Studies.

Leanne Schut

Leanne is a first-year MA student in Developmental Psychology. She completed her Bachelor’s degree in Honours Psychology with a Research Intensive Specialization and a minor in Communication Studies at the University of Waterloo. Her current research continues her undergraduate work on causal reasoning, focusing on how people reason when faced with inconsistencies. She is also interested in how children’s natural ways of learning and interacting with their environment can support their understanding of new math concepts.
