Final answer:
Conducting research in cultural anthropology by joining another culture is called participant observation. This involves living within the culture, and is key in creating an in-depth study known as an ethnography. Modern cultural anthropology also prioritizes collaborative methods for ethical research practices.
Step-by-step explanation:
Conducting research in cultural anthropology by joining another culture and doing what those people do is called participant observation. This research method involves the anthropologist living within a cultural community and collecting information through observation of and participation in the culture. This immersion can encompass adopting local customs, dress, diet, language, and social practices, and is considered a key component of ethnographic research.
Through participant observation, anthropologists aim to gain an insider's perspective, allowing for a more accurate and ethical representation of the culture. They may produce an ethnography, an in-depth study of the culture, as part of their fieldwork. It should be noted that modern cultural anthropology emphasizes collaborative methods to involve community members in the research process, ensuring that findings are beneficial and respectful to the subjects studied.
