Final answer:
Key leadership behaviors that contribute to group procedural functions primarily include flexibility and adaptability, rather than authoritarianism, isolation, or indifference. Various leadership styles like democratic, laissez-faire, and authoritarian can impact group dynamics in different ways.
Step-by-step explanation:
Key leadership behaviors contributing to the procedural functions of a group include flexibility and adaptability. These traits are essential because they allow a leader to respond to changing circumstances within a group setting. Authoritarianism is another style, where the leader issues orders and assigns tasks, often with a strong focus on meeting goals; this can be necessary in some high-stress or fast-paced situations. In contrast, isolation and indifference are not conducive to procedural functions as they hinder communication and progress within a group.
Different styles of leadership, such as democratic leaders, who encourage group participation and consensus building, laissez-faire leaders, who adopt a hands-off approach, and authoritarian leaders, who provide clear directives and structure, can all influence group dynamics and effectiveness depending on the context and the group's needs.
