sijia.wu@mail.utoronto.ca | Google Scholar | ResearchGate 

Si Jia received her BA in philosophy with a minor in psychology from University of Toronto and her MA in developmental psychology and education from Ontario Institute for Studies in Education. During her undergraduate studies, she was also a Research Assistant and Lab Manager at Dr. Kang Lee's Development Lab, working on moral reasoning of children between ages 3-12. For her MA thesis, she validated the use of Transdermal Optical Imaging for assessment of stress based on Heart Rate Variability in comparison to electrocardiography. Additionally, she has explored the use of Transdermal Optical Imaging for accurate and reliable measure of physiological (e.g., heart rate, breathing rate, blood pressure, glycated hemoglobin) and psychological states (e.g., stress, emotions, lies), with a focus on stress in university students. Currently, she continues her research on stress while pursuing a new line of research on children's emotional engagement with manga stories.

PhD Candidate (Developmental Psychology and Education)

wenjin.sun@mail.utoronto.ca | Google Scholar | ResearchGate

Wenjin Sun holds a Bachelor of Science in Applied Psychology from Shandong Normal University and a Master of Education from Hangzhou Normal University. During her graduate studies, she extensively examined contextual factors—such as praise, environmental cues, and emotional states—that impact children's propensity to engage in cheating behavior. Her master's thesis focused on elucidating the influence of various cognitive factors, including intelligence, on children's ethical decision-making. Her current research pursuits encompass several dimensions:1) Investigating the multifaceted factors affecting children's cheating behavior, including but not limited to intelligence, theory of mind, executive function, personality traits, and moral judgement. 2) Exploring the intricate interplay between children's sense of power and their inclination towards cheating behavior. 3) Examining the correlation between children's prosocial behavior and their sense of power. Currently there are 5 research assistants in Wenjin’s team. Two are graduate students, from the University of Toronto and Columbia University, and three are undergraduate students, from McGill University.

Tiffany received her BSc in psychology with a minor in biology, MASc in Developmental and Communication Science, and PhD in Psychology from the University of Waterloo. Following her PhD, she was a postdoctoral fellow at the University of Toronto, Scarborough. Her research focuses on cognitive development in early childhood, specifically social cognitive development.
