Cartwright and Zander (1971) defines the dynamics of group as a field of research dedicated to increasing knowledge about the nature of the groups, the laws of its development and its interrelations with individuals, another group and higher institutions. (quoted in Mailhiot Bernard Dinamica de Genesis de Grupo. 4.2.-PRINCIPLES OR FUNDAMENTALS OF GROUP DYNAMICS. We find principles or theoretical foundations of this discipline scattered in the context of social sciences. In this sense, has contributed to its development, expansion and maintenance: Sociology, cultural anthropology, collective psychology, social psychology, field theory, factor analysis, formal organization, the sociometry, analysis of the reciprocal action, social work of Group, gestalt, psychoanalysis, the movement’s development of human potential, psychotherapy, family, etc., and recently the third force and humanistic psychology. In this sense, we have that such principles are: the environment, reduction of the intimation, distributed leadership, flexibility, compression of the process, consensus, the formulation of objectives and continuous evaluation. Then describe each of this principles: 1) environment: group must interact within a physical environment, how and suitable for the type of activity that has developed. Because the atmosphere directly influences the atmosphere or climate of the group, therefore, must be arranged as to contribute to the participation, the spontaneity and the cooperation of all its members.
The premises should not be too large or too large nor too small, must save the last detail, so that members of the group can see comfortably to exchange ideas, perceptions feelings fantasies, etc., face to face. (2) The reduction of bullying. Interpersonal relationships should be kind, cordial, Frank, open, open, appreciation and mutual collaboration. The fact of interacting in a group, can produce feelings of fear, inhibition, hostility and shyness, coming to produce intimidation or physical or psychological evasion of some members of the group. The reduction of tensions and conflicts, promotes the work and productivity of groups.
