Riemer (1955) has argued that gaze is an ‘expression of affect’ between individuals. Kendon (1967) writes that the direction of gaze has a regulatory and expressive function, and ‘fluctuations in the amount of eye-contact during the course of one conversation showed that it was inversely related to the amount of emotionality displayed by the participants'. Also that it has a regulatory function which governs the pattern of social interaction. Argyle and Dean (1965) made similar observations in their concept of intimacy. They postulate that there is an Intimacy Equilibrium; Intimacy is a function of eye-contact, physical proximity, intimacy of topic, amount of smiling etc. They have shown that an alteration in one variable produces a change in the others until an equilibrium is reached. Exline et al. (1965, 1966, 1967) have described other aspects of eye-contact in relation to sex, dependency, social reinforcement, affiliative needs and affective relations. These findings support those of Kendon and Argyle.
