Final answer:
The group norm in Group A, where members help others complete the project, is a task norm, which is a part of social norms that guide behavior within groups to achieve objectives.
Step-by-step explanation:
In Group A, the norm where members help others after finishing their individual tasks until the entire project is complete can be classified as a task norm. This type of norm is focused on the expectations and behaviors that ensure group members contribute to the group's objectives and goals. It's a subcategory within social norms, which are the shared expectations and rules that guide the behavior of people within social groups. These norms can include various aspects of behavior, such as how to act, what topics are appropriate to discuss, and what clothing is suitable to wear within the group setting.
The task norm specifically relates to the actions directly connected to the performance and achievement of the group's goals. In the context of a learning environment, this norm ensures that collaborative projects are completed efficiently and collectively. In such groups, the members are often influenced by the desire to contribute effectively and support the communal effort to reach a shared objective, reflecting the principles of both normative social influence and task cohesion.
