A Researcher Gathers a Sample of Individuals from Indian Families

A researcher gathers a sample of individuals from Indian families who were raised in North America (and are presumably Indian-American biculturals) to participate in her study. She randomly assigns participants to either draw a diagram showing the hierarchical relationships among their family members, or to list ways in which their family members are equal to each other. After this experimental manipulation, all participants are asked to sing "happy birthday" out loud in front of several people, and to report how embarrassed they felt during this task. The researcher is probably interested in learning:

A) whether Indian culture promotes embarrassment to a greater extent that North American culture.
B) whether power distance, as an aspect of culture, causally influences people's experience of embarrassment.
C) whether cultural priming affects people's ability to sing well.
D) whether Indian culture is more hierarchical than North American culture.
