In my Communications class we are discussing how eye contact is important when giving an oral presentation. My teacher asked the question which countries and cultures don't use eye contact? What assumptions and rules do they have concerning lack of eye contact?

I thought I could find something online that would help me, but I haven't found anything. Can someone helop me please? Thanks.

Some cultures do find it rude when you show eye contact. Many Asian cultures do believe so. I am not sure what in particular. Read bellow if it helps. If I am not answering your questions, please tell me:

Nonverbal communication expresses meaning or feeling without words. Universal emotions, such as happiness, fear, sadness, are expressed in a similar nonverbal way throughout the world. There are, however, nonverbal differences across cultures that may be a source of confusion for foreigners. Let's look at the way people express sadness. In many cultures, such as the Arab and Iranian cultures, people express grief openly. They mourn out loud, while people from other cultures (e.g., China and Japan) are more subdued. In Asian cultures, the general belief is that is is unacceptable to show emotion openly (whether sadness, happiness, or pain).
