1) Environmental psychology: using a general model that explains the relationship between the environment, work, and stress, and then examining specific elements, such as spatial organization or light levels in the workplace, to confirm or refute an existing model.
2) Education: first adopting a holistic theory of learning and then testing specific strategies on students or in classrooms.
3) Urban planning: developing a general model for the use of public spaces in the city, and then testing a specific park or street design before implementing the model on a larger scale.
