Welcome to the Social Psychophysiological Research & Quantitative Methods Laboratory (SPRQL; “sparkle”) at the University of Toronto. Research at SPRQL focuses on how social interactions between strangers and friends affect the way people think about and approach the world, particularly within the domain of intergroup relations. Directed by Dr. Elizabeth Page-Gould, the lab specializes in multi-person, longitudinal, psychophysiological, and behavioural data collection across both laboratory and field settings. The lab also specializes in advanced statistical analysis and quantitative innovation. Both the research conducted in SPRQL and the training environment the lab offers represent a unique combination of advanced research methods from social psychology, psychophysiology, and statistics.
