Final answer:
The term that refers to the belief that culture makes no difference is 'cultural encapsulation,' which is not included in the given options. Cultural relativism is recognizing a culture based on its own merits, while ethnocentrism is the belief in the superiority of one's own culture.
Step-by-step explanation:
The concept described by Cross and colleagues where culture is perceived as making no difference aligns most closely with cultural encapsulation. This term is not presented in the given options, so there seems to be a misunderstanding in the question provided. Nonetheless, cultural relativism is the recognition and practice of understanding a culture based on its own standards and values rather than through the lens of one's own culture. A belief in cultural relativism requires an open mind and a willingness to see cultural practices and beliefs as valid within their own contexts. This contrasts with ethnocentrism, which is the belief that one's own culture is superior to others. The correct answer to the original question, as it seems none of the options provided actually refer to the belief that culture makes no difference, would ideally be 'cultural encapsulation' if it were available as a choice. Since it is not, the provided options do not adequately answer the question.
