The role in a group that sustains cohesion by encouraging others is:

• A. The observer.
• B. The task-focused leader.
• C. The harmonizer or encourager.
• D. The challenger.

Answer: (C)

In group dynamics, keeping the group close and functioning well depends on social support and inclusive behavior. The harmonizer or encourager is the role that embodies this by actively promoting a positive, collaborative climate. They notice when someone is quiet or discouraged, invite input from all members, acknowledge and validate contributions, and help resolve small tensions before they grow. This ongoing encouragement helps people feel valued, reduces defensiveness, and builds trust, so members are more willing to participate and cooperate. When encouragement comes from this role, the group stays cohesive even through minor disagreements, because members feel supported and connected.

The observer tends to monitor rather than influence, which doesn’t directly sustain cohesion. The task-focused leader concentrates on getting things done, which can overlook the relational side that keeps the group united. The challenger pushes for critical scrutiny or debate, which can spark conflict rather than maintain harmony. The harmonizer or encourager is best suited to sustain cohesion by fostering positive interactions and a supportive environment.
