Welcome to the Social & Motivational Processes in Physical Activity Laboratory (SiMPL) website. SiMPL is directed by Dr. Alan L. Smith and involves several graduate and undergraduate students at Michigan State University. Our work targets social and motivational processes within sport, physical education, and other youth physical activity contexts. We are interested in how physical activity contributes to psychological and social development as well as how to promote physical activity motivation and behavior in young people. Our work draws heavily from developmental, social, and sport psychology perspectives and we collaborate closely with colleagues in clinical psychology, motor control, neuroscience, and physical education pedagogy. We invite you to explore the menus above to learn more about our work.
