Professional Experience

Dr. Selmeczy joined the Psychology Department in Fall of 2019. Her research program focuses on understanding 1.) how individuals introspect on their memory and how these thoughts guide decision-making, 2.) the environmental and contextual factors that influence memory decisions, and 3.) how these abilities develop throughout the lifespan, particularly during childhood. Her research has been funded by federal agencies such as the National Institutes of Health and published in leading journals such as Proceedings of the National Academy of Sciences of the United States of America and Child Development.
