Trans-Contextual Model. Together with my colleague Nikos Chatzisarantis, I have developed an integrated model that explains the processes by which autonomous motivation and autonomy support for activities (e.g., physical activity, learning) in an educational setting relates to autonomous motivation, attitudes, and intention toward, and actual participation in, activities outside of school. The model has been applied in numerous educational contexts (e.g., physical education classes, math and science lessons) and extra-mural behaviors (e.g., physical activity, math and science homework).

Theory Integration. I am keen on the integration of theories to address shortcomings of current theory, such as redundancy across constructs and boundary conditions, and, in so doing, facilitate more comprehensive, effective prediction of behavior. In particular I am interested in integrating theories such as self-determination theory with theories of social cognition like the theory of planned behavior and reasoned action approach, and incorporating constructs that represent non-conscious processes (e.g., implicit attitudes, habit) as behavioral determinants within current social cognition models.
