    Shannon is a 4th year Psychology student completing her honours thesis with the EEL lab. Her research will investigate how young children’s belief revision capabilities differ relative to their age and theory of mind. Her study will begin November 2024. Contact the lab to learn more!

  • Emma Gray - Directed Lab

    Emma is a 4th year psychology major and sociology minor student. Her directed lab project involves looking at how affection from parents can impact the movement patterns of young kids. She's very interested in theory of mind and executive functioning research, and is super excited to experience some of this research first hand in the EEL.

  • Taylor Vilardo - Directed Lab

    Taylor Vilardo is a fourth year psychology major and french minor student. Her directed lab project investigates the development of theory of mind in children aged 3-6. Using EEG, her project explores how children's brain activity responds as they play an animated game about birds, helping to uncover insights into how young kids understand that others have thoughts and beliefs different from their own. Taylor is excited to delve deeper into social and cognitive development research through hands-on experience with this project.
