Final answer:
The individual in a small group who tries to limit lengthy contributions from others plays a role akin to a gatekeeper, ensuring effective communication and decision-making. This role is key in primary groups with close ties and in maintaining group cohesiveness. Such roles are essential across both small groups and larger institutions.
Step-by-step explanation:
In terms of small group relational roles, the individual trying to limit lengthy contributions of other group members is likely acting in a role that maintains group focus and ensures effective use of time. This person might be referred to as the 'gatekeeper' or 'expediter' in group dynamics literature. Their role is crucial in preventing one individual from dominating the conversation and ensuring that everyone has a chance to contribute, which, in turn, helps to maintain the cohesiveness and decision-making capacity of the group.
Primary groups, with their complex relationships and closer ties, often require each member to fulfill multiple roles to support group function. Unlike larger groups or formal institutions, where specific roles may be more rigidly defined, small groups rely on a more flexible and interpersonal approach to managing interactions and responsibilities.
It is important to note that these roles are an important component of both small groups and large institutions, ensuring that the goals of the collective are met and that the group can function efficiently despite the potential for collective action problems, which can become more pronounced as group sizes increase.
