While Gale Obcamp, an American artist, was giving a speech on the art of Japanese brush painting to an audience that included visitors from Japan, she was confused to see that many of her Japanese listeners had their eyes closed. Were they turned off because an American had the nerve to instruct Japanese in their own art form? Were they deliberately trying to signal their rejection of her? Obcamp later found out that her listeners were not being disrespectful. Japanese listeners sometimes close their eyes to enhance concentration. Her listeners were showing their respect for her by chewing on her words. Some day you may be either a speaker or a listener in a situation involving people from other countries or members of a minority group in North America. Learning how different cultures signal respect can help you avoid misunderstandings. Here are some examples. In the deaf culture of North America, many listeners show applause not by clapping their hands but by waving them in the air. In some cultures, both overseas and in some minority groups in North America, listeners are considered disrespectful if they look directly at the speaker. Respect is shown by looking in the general direction but avoiding direct eye contact. In some countries, whistling by listeners is a sign of approval while in other countries it is a form of insult.
