The construction of self-administered, programed, culture training manuals, called "Culture Assimilators," is described here. These programs provide an apparently effective method for assisting members of one culture to interact and adjust successfully with members of another culture. Culture assimilators have been constructed for the Arab countries, Iran, Thailand, Central America, and Greece. The paper describes the steps involved in the development of these programs, as well as briefly reviewing studies validating the Culture Assimilator programs under laboratory and field conditions.
