As we gain experiences with particular type of social institution, we develop rules how to behave in those situations. when an individual travels by airplane for the first time, there is initial confusion about where to go in the airport. what to do with his/her luggage, how to act towards flight attendants and so on. with in experiences the traveler learns the “rules” for checking in, boarding the plane, stowing carry on items, ordering foods and drinks, interacting with seat-mates, and the likes. Once acquired, these rules prove to be applicable in airports and on airplane almost anywhere in the world. The set of rules we developed for airplane travel illustrates how past experience became structured knowledge for use in processing new social information. Such knowledge structure are known as Schemas. Schemas are sets of rules or features that represent what we know about categories of objects or events in general.
