Final answer:
The stage of group development where members are reserved and uncomfortable is known as the forming stage. This period is marked by the beginnings of socialization and conformity to new roles within the group. Eventually, the group may evolve to become an established organization or decline if its goals are met or it loses relevance.
Step-by-step explanation:
When new members join a group and feel reserved and uncomfortable, this is typically known as the forming stage of group development. This stage is characterized by members being polite and somewhat impersonal as they start to learn about one another and assess the boundaries of group behavior. People often avoid conflict and controversy to maintain a comfortable group atmosphere, and a leader may emerge to guide the group toward its goals.
A clear example of societal groups and institutions undergoing transformation can be seen in scenarios such as joining a new school, fraternity, or sorority, where individuals undergo a form of socialization. They must adapt to new cultural behaviors and expectations, leave behind old identities, and come together with others to form a cohesive unit. The acceptance of shared aims and conformity to new roles within a group or movement signifies progression from the forming stage to later stages like coalescence and institutionalization, as outlined by sociologists.
In movements or when forming community groups, this development process may lead to a sense of community and shared purpose, moving beyond initial uncertainties and forming a collective identity. As groups evolve, they may reach the institutionalization stage where the organization becomes established and formalized, or they may enter into decline if they achieve their goals or become irrelevant.
