Whether the eyes are "the windows of the soul" is true or not, it is a fact that they are especially important in interpersonal communication. In a conversation, eye contact is important because more or less eye contact can create communication barriers (32). In relationships, eye contact serves to show intimacy, attention, and influence.
Eye contact can mean different things in different cultures. In some Spanish-speaking countries, children show respect to an older person by not looking directly into the person’s eyes during a conversation (33). In other countries, looking into a person’s eye is expected. For example, if you don’t do it in the United States, people may think that you are afraid, embarrassed, or angry (34). Too little eye contact may be viewed negative, because it may express a lack of interest, attention and even trust. "Never trust a person who doesn’t look you in the eyes." In the Middle East, direct eye contact during a conversation lasts longer than in many other parts of the world (35). Some westerners who are not used to this may feel uncomfortable for they think it rude to stare, especially at strangers.
