Final answer:
An authoritarian leader provides specific instructions and is suited for situations where team members require clear direction. This style ensures efficiency and quick decisions but can alienate team members if used excessively. Other leadership styles include democratic, expressive, and laissez-faire, each with its own approach to decision-making and group dynamics.
Step-by-step explanation:
A authoritarian leader gives specific instructions; this is a good choice when members are unsure of expectations. In the context of leadership styles, an authoritarian leader is typically seen as someone who is goal-oriented with a primary focus on tasks. They issue orders and assign tasks without seeking much feedback from group members. They can efficiently make quick decisions and bring expertise to situations where that is crucial. However, this leadership style may result in alienation among team members if overused.
Contrastingly, democratic leaders promote participation and consensus in decision-making, though this process can be slow. Expressive leaders focus more on the emotional well-being of the group, and laissez-faire leaders take a hands-off approach, ideal for highly motivated groups but potentially leading to a lack of progress without clear direction.
