Editing Social exchange theory (section)

== Aging ==
The basis of social exchange theory is to explain social change and stability as a process of negotiating exchanges between parties. These changes can occur over a person's life course through the various relationships, opportunities, and means of support. An example of this is the convoy model of support, this model uses concentric circles to describe relationships around an individual with the strongest relationships in the closet circle. As a person ages, these relationships form a convoy that moves along with the person and exchanges in support and assistance through different circumstances that occur.<ref>{{cite journal |last1=Antonucci |first1=T.

Within this model, there are different types of support ([[social support]]) a person can receive, those being intangible, tangible, instrumental, and informational. Intangible support can either be social or emotional and can be love, friendship and appreciation that comes with valuable relationships. Tangible support are physical gifts given to someone such as land, gifts, money, transportation, food, and completing chores. Instrumental support are services given to someone in a relationship. Finally, informational support is the delivering of information that is helpful to an individual.<ref>{{Cite web|url=http://www.med.upenn.edu/hbhe4/part3-ch9-key-constructs-social-support.shtml|title=Health Behavior and Health Education {{!}} Part Three, Chapter Nine: Key Constructs Social Support|website=www.med.upenn.edu|language=en|access-date=2018-03-28}}</ref>
