My interests are in the area of social psychology and health. I am currently investigating goal conflict as a barrier to regular physical activity. The question behind this research is whether goal conflict reduces performance of physical activity by various means, including the loss of enjoyment or intrinsic satisfaction from exercise, conditioning of negative emotions to exercise objects and settings, weakening of psychological structures underlying the intention to exercise, and justifying ongoing underperformance of personal exercise goals. I have also worked in the area of healthy aging and have a long-term interest in topics such as perceived control, collective self-esteem, and social comparison. I thank the Social Sciences and Humanities Research Council of Canada and Sport Canada for support of my current work.
