A social interaction is an exchange between two or more individuals and is a building block of society. This interaction can be studied between groups of two (dyads), three (triads) or larger groups. By interacting with one another, people design rules, institutions and systems within which they seek to live.
It is now time to define social interaction. As previously discussed, behavior comes in many forms–blinking, eating, reading, dancing, shooting, rioting, and warring. What then distinguishes social behavior? Behavior that is peculiarly social is oriented towards other selves. Such behavior apprehends another as a perceiving, thinking, Moral, intentional, and behaving person; considers the intentional or rational meaning of the other’s field of expression; involves expectations about the other’s acts and actions; and manifests an intention to invoke in another self certain experiences and intentions. What differentiates social from nonsocial behavior, then, is whether another self is taken into account in one’s acts, actions, or practices.
For example, dodging and weaving through a crowd is not social behavior, usually. Others are considered as mere physical objects, as human barriers with certain reflexes. Other marchers are physical objects with which to coordinate one’s movements. Neither is a surgical operation social behavior. The patient is only a biophysical object with certain associated potentialities and dispositions. However, let the actor become involved with another’s self, as a person pushing through a crowd recognizing a friend, a marcher believing another is trying to get him out of step, or a surgeon operating on his son, and the whole meaning of the situation changes.
