Which group model allows for the emergence of unique roles and responsibilities among three people?

The triad is a group model that consists of three individuals, and it allows for the emergence of unique roles and responsibilities among its members. In a triad, the dynamics are more complex than in a dyad, which involves only two individuals. This complexity creates opportunities for specialization of roles, as each member can take on different responsibilities based on their strengths or preferences, leading to unique interactions and functions within the group.

For example, in a triad, one person may take on the role of a leader, another might serve as a mediator, and the third might focus on creative ideas or planning. This division of roles can enhance the group's effectiveness and can contribute to a more intricate social structure. The interdependencies and interactions in a triad can also lead to the development of alliances or coalitions within the group, further illustrating the unique dynamics that arise from having three members.
