Group Dynamics: Formation, Types, and Cohesion Principles

Defining a Group

A group consists of a plurality of interrelated individuals, each performing a particular role, working towards common goals, and interacting to varying degrees according to a set of established guidelines.

Classifications of Groups

Groups can be classified according to various criteria:

Group Types by General Criteria

  • The Crowd: Typically more than 50 individuals with little connection between them, and often with unclear objectives.
  • The Band: Composed of a few individuals where similarity forms the basis of their relationship. Adaptation effort is minimal, and relationships tend to be superficial.
  • Grouping: A variable number of members (tens to hundreds) sharing common goals and frequent meetings, though relationships may remain shallow.
  • Primary Groups: Small groups characterized by strong emotional ties and a high degree of cohesion.
  • Secondary Groups: Larger social systems, often more formal and less personal than primary groups.

Groups Based on Individual Relationship

  • Belonging Groups: Groups to which an individual belongs, often without personal choice.
  • Reference Groups: Groups with which an individual identifies, adopting their values and behaviors, even if they are not a formal member.

Groups Based on Purpose

  • Formal Groups: Deliberately formed, often as part of an organization. Organizational goals typically prevail over individual rights, and members meet to achieve a common objective.
  • Informal Groups: Formed spontaneously based on sympathy or mutual attraction (e.g., friends).
  • Externally Designated Groups: Groups formed by classifications or labels applied by others (e.g., “the homeless”).

Groups from an Anthropological Perspective

  • Mass Group: Characterized by sentimental and emotional drivers. Often reckless, irresponsible, highly suggestive, and manageable.
  • Organizational Group: Focuses on the role an individual plays within a structure. While potentially helpful for achieving tasks, it may not prioritize individual growth and can sometimes be discriminatory.
  • Community Group: Values the individual as a whole person, respecting both their weaknesses and strengths. This type of group fosters trust, respect, and affection.

Stages of Group Formation

Groups typically progress through several stages:

  • Forming Stage: Characterized by expectation and anxiety. Members are unsure how to act and often seek security from a facilitator or leader.
  • Storming Stage (Conflict): Marked by opposition, competition, and the formation of alliances. This stage is crucial for group maturation.
  • Norming Stage (Organization): A sociological leader often emerges, and the group begins to identify as a collective, using terms like “us.”
  • Performing Stage (Interaction): The group achieves high cohesion, affection, and productivity. Leadership is often shared among members.

Indicators of Group Maturity

A mature group typically demonstrates the following:

  • Successful progression through all previous formation stages.
  • Effective resolution and overcoming of the conflict (storming) phase.

Group Cohesion

Group cohesion refers to the extent to which a group feels united and self-satisfied. Cohesion has a positive effect on groups, increasing their productivity, fostering cooperation, and strengthening the feeling of solidarity among members.

Factors Influencing Group Cohesion

Group cohesion is determined by a combination of intrinsic and external factors:

  • Intrinsic Factors:
    • Sympathy and affinity among members.
    • Shared experiences of success and failure.
    • Strong group culture.
    • Satisfaction of individual and collective needs within the group.
  • External Factors:
    • The leadership style of the formal group leader.
    • Support or influence from an external entity or unit.

Strategies for Fostering Cohesion

Formal leaders must empower and implement strategies to support group cohesion, including:

  • Cultivating a positive emotional climate that encourages consensus and compliance with group norms.
  • Providing a physical or virtual space that creates a warm and welcoming environment.
  • Establishing clear objectives for the group.
  • Ensuring the group’s ability to adapt to changing circumstances, as rigidity can hinder cohesion.
