This research laboratory, directed by Professor Patrick Gaudreau, studies the interplay between motivation, self-regulation, and achievement. We are conducting empirical studies with diversified populations of students and athletes. A central goal of our research program is to understand the role of personality (i.e., perfectionism, optimism), motivational (goals, motives, needs) and self-regulation processes (i.e., goal setting, planning, coping) in facilitating the attainment of personal goals and the development of optimal functioning. Our research tries to delineate how these processes change and evolve across time using longitudinal designs with both correlational and experimental research methods. Our mandate is to generate evidence-based guidelines to promote achievement and well-being across time, situations, and contexts.
