Whether the eyes are the windows of the soul is debatable, that they are intensely important in interpersonal communication is a fact. During the first two months of a baby's life, the stimulus that produces a smile is a pair of eyes. The eyes need not be real a mask with two dots will produce a smile. Significantly, a real human face with no eyes will not motivate a smile, nor will the sight of only one eye when the face is presented in profile. This attraction to eyes as opposed to the nose or mouth continues as the baby matures. In one study, when American four-year-olds were asked to draw: people, 75 percent of them draw people with mouths, but 99 percent of them draw people with eyes. In Japan, however, where babies are carried on their mother is back, infants do not acquire as much attachment to eyes as they do in other cultures. As a result, Japanese adults make little use of the face either to encode or decode meaning. In fact, Argyle reveals that the proper place to focus one's gaze during a conversation in japan is on the neck of one's conversational partner. The role of eye contact in a conversational exchange between two Americans is well defined. Speakers make contact with the eyes of their listener for about one second, then glance away as they talk in a few moments they reestablish eye contact with the listener or reassure themselves that their audience is still attentive, then shift their gaze away once more. Listeners, meanwhile, keel) their eyes on the face of the speaker, allowing themselves to glance away only briefly. It is important that they be looking at the speaker at the precise moment when the speaker re-establishes eye contact. If they are not looking, the speaker assumes that they are disinterested and either will pause until eye contact is resumed or will terminate the conversation. Just how critical this eye maneuvering is to the maintenance of conversational flow becomes evident when two speakers are wearing dark glasses there may be a sort of traffic jam of words caused by interruption, false starts, and unpredictable pauses.
