Suppose you have a part-time job working with residents of an assisted-living facility. One of the people you help care for is an eighty-year-old retired kindergarten teacher, whose morale is very low following the death of her husband. You suggest that she consider going out for walks with the other residents in hopes it will lift her spirits. For sociologists, this is a good example of theory.

Activity theory

Explanation:

Activity theory is a framework of original theory rather than a predictive theory. In this theory, there are hierarchical levels for the motivation of human beings. People are linked with their cultural context through social interactions.  

This theory has five basic principles.

The human activities are directed towards the objects.

The human activities are inscribed by the social knowledge

Human activities are evolved.  

In the activity theory, aging people still motivated at their near death bed. After retirement, they even involved inactivity or any kind of job. This is a good example of activity theory.
