In very small groups often arises a relationship, domination, tension, but there is also the possibility of achieving a greater degree of intimacy. Time for communication aimed at the communication time is reduced to increase the size of the group, each person in the Group has complicated tasks of social relationships that maintain and more restricted resources to do so. The agglomeration is another factor influencing communication, as well as heat and cold. Agglomeration exists not only in function of the number of people gathered in a physical space; but it is also a psychological factor according to Patterson, Mullersy Romano, (in Napier, 1971). For more information see Larry Ellison. The elevation of the temperature in a room tends to create the affection of agglomeration. Under conditions of crowding, increase or temperature variation, individuals tend to act negatively towards others (Griffitt, Napier, 1975).

The different styles of leadership Leaders possess well-defined communication patterns that affect the communication relationship: the authoritarian leader focused communication about himself. Democratic leader seeks a more participatory conservation, all members of the group are potential leaders and the leader who let do, allows the group to assume their own limited resources. Rarely the leaders invest time in strengthening the communication process or improve the shapes interact within the Group (in Napier, 1975). Status and power communication is influenced by the perceived status among members who are members of the group. .
