<P> Therefore, higher - context cultures tend to correlate with cultures that also have a strong sense of tradition and history, and change little over time . For example, Native Americans in the United States have higher - context cultures with a strong sense of tradition and history . The focus on tradition creates opportunities for higher context messages between individuals of each new generation, and the high - context culture feeds back to the stability hence allows the tradition to be maintained . This is in contrast to lower - context cultures in which the shared experiences upon which communication is built can change drastically from one generation to the next, creating communication gaps between parents and children, as in the United States . </P> <P> Culture also affects people's facial expression, an experiment done by the University of Glasgow shows that Western Caucasians and East Asians have different understanding in the facial expression signals of the 6 basic emotions, which are the so - called "universal language of emotion"--happy, surprise, fear, disgust, anger and sadness . The results show that Western Caucasians tend to distribute their expressive features across the face, including eyebrows and mouth; while the East Asians tend to use their eyes to express most of the emotions, especially by changing the direction of gazing, which turns out to be far less exaggerating than the Westerners . </P> <P> This phenomenon can also be explained by using the high - and low - context culture theory . By mapping the performance on facial expression and the cultural backgrounds of the participants, we can tell that more exaggerating expressions of emotion tend to correlate with relatively lower - context culture (Western Caucasian culture), while subtler facial expressions belong to higher - context culture (East Asian culture). This is because, in a low - context cultural environment, people tend to express themselves as explicit as possible, thus exaggerating facial expression becomes a complementary tool for further elaboration of the speaker's meaning by conveying speaker's emotion vividly and effectively avoid misunderstanding . </P> <P> On the contrary, a high - context culture usually indicates an enormous amount of "taken for granted" shared knowledge, therefore people believe that limited amount of information should be enough for successful communication, which means the "complementary tool" function of facial expression becomes less important here . Hence people coming from high - context cultural background tend to express their emotion via facial expression more subtly, in the case of this study, the East Asians would convey most of their feeling via their eyes . </P>
