CHAPTER V SOCIAL CONTACTS I. INTRODUCTION 1. Preliminary Notions of Social Contact The fundamental social process is that of interaction. This interaction is (a) of persons with persons, and (b) of groups with groups. The simplest aspect of interaction, or its primary phase, is contact. Contact may be considered as the initial stage of interaction, and preparatory to the later stages. The phenomena of social contact require analysis before proceeding to the more difficult study of the mechanism of social interaction. "With whom am I in contact?" Common sense has in stock ready answers to this question. There is, first of all, the immediate circle of contact through the senses. Touch is the most intimate kind of contact. Face-to-face relations include, in addition to touch, visual and auditory sensations. Speech and hearing by their very nature establish a bond of contact between persons.
