Social dynamics refers to how individual behaviors within a group influence and are influenced by the group. Groups go through developmental phases including pre-group formation, an initial phase of settling in and establishing norms/roles, a working phase focused on the group's task, and a termination phase. The initial phase involves anxiety about acceptance and conflicts around control that must be resolved. During the working phase, the group works cooperatively on its task. Termination involves evaluating accomplishments but can also be painful as relationships end.
