Researchers who use the _____ approach to studying intercultural communication are interested not only in understanding human be

Leni [432]

Answer:

Critical

Explanation:

The critical approach views reality as subjective and focuses on the importance of studying the context in

which communication occurs. Critical scholars view culture in terms of power struggles and study cultural

differences specifically as they relate to unequal distribution of power within society. They are interested not only in studying human behavior across cultures, but also in effecting change in society. They believe that by their study and analysis of the role of power in cultural encounters, they can assist people in opposing the oppressive forces in society.

Critical scholars believe that the goal of intercultural research is to identify and make explicit power

differences in order to liberate those individuals who lack power in society. In examining the role of

communication in creating group identities, critical scholars wish to deconstruct assumptions about reality in order to challenge social realities that reinforce exploitation of some groups within society. In most nations, power is not distributed equally between the majority and minority cultures.
